[tex]\frac{14}{2}[/tex] [tex]\frac{490}{x}[/tex] then cross multiply. 14*x = 14x 490*2 = 980
So 980 = 14x (divide by 14)
x = 70
So 70 adults

What is the value of x? What is the value of y?
Answer:
x = 45/2y = 10Step-by-step explanation:
Both angles that have the "x" variable are the same and both angles that the "y" are the same since they are congruent meaning they are the same angle measure.
Solve for x.
6x - 5 = 8x - 50
~Add 5 to both sides
6x = 8x - 45
~Subtract 8 to both sides
-2x = -45
~Divide -2 to both sides
x = 45/2
Solve for y.
2y + 30 = 3y + 20
~Subtract 30 to both sides
2y = 3y - 10
~Subtract 3y to both sides
-y = -10
~Divide -1 to both sides
y = 10

help on math angle question. ik its easy but I have no idea how math works :D
Answer:
71º is measure of angle A
19º is measure of angle B
Step-by-step explanation:
complementary angles are angles that equal to 90º
so let's add the terms (from angles A & B) and set them equal to 90º
3x+2 + x-4 = 90
4x -2 = 90
add 2 to both sides to get rid of the 2 on the left side and isolate our similar terms
4x = 92
divide both sides by 4
x=23
We're not done though, we must plug in our x value to Angle A terms and Angle B terms.
(3(23) + 2)º = measure of Angle A (solve for both of them)
(23-4)º = = measure of Angle B
3(23) + 2 =
3(23) = 69 (add the 2)
71º is measure of angle A
23-4 = 19º
19º is measure of angle B
double-check
71+19 = 90º
It works
Answer:
71º is measure of angle A
19º is measure of angle B

Find the slope. ( include whether positive or negative.)
Answer:
that is a negative slope
but dont know how to find the slope sorry
Step-by-step explanation:
[tex]\tt Step-by-step~explanation:[/tex]
Remember: To find the slope, we use the equation Rise/Run.
[tex]\tt Step~1:[/tex]
Let's find the rise first. Rise = How many units it goes up/down We can count down 6 units from the origin. Our rise is - 6.
[tex]\tt Step~2:[/tex]
To find the run. we count left/right. We could count 8 units. Our run is 8.
The slope is negative because it slopes downwards. If the slope is positive, then the line would be rising up.
[tex]\tt Step~3:[/tex]
To find the slope, we use the formula rise/run.
[tex]\tt \frac{-6}{8}=-\frac{3}{4}~or~ -0.75[/tex]
[tex]\large\boxed{\tt Our~final~answer:~m=-\frac{3}{4}~or~-0.75;~Negative~slope}[/tex]

===========================================
Explanation:
You have the right idea, but keep in mind that it says consecutive even integers. So we're only looking at numbers like 2,4,6,8,... and these numbers must follow one right after another. If that "even" wasn't there, then your answer and steps would be 100% correct.
If x is an even number, then x+2 is the next even number, and x+4 is the one after that.
Add them up to get
(x)+(x+2)+(x+4)
x+x+2+x+4
(x+x+x)+(2+4)
3x+6
Then divide by 3 to compute the average
(3x+6)/3
3x/3 + 6/3
x+2
Set this average equal to 48 and solve for x
x+2 = 48
x = 48-2
x = 46 is the smallest number
x+2 = 46+2 = 48 is the middle value
x+4 = 46+4 = 50 is the largest
Note how the middle value is exactly the average. This is because we have symmetry going on here.
It's similar to how the average of the set {1,2,3} is 2 since 2 is in the middle.
-------------------
Check:
add the values: 46+48+50 = 144
divide by three: 144/3 = 48
The average of the set {46,48,50} is 48
This confirms the answer

y is inversely proportional to x . When y = 3 , x = 20 Work out x when y = 12
Answer:
x = 5 when y = 12
Step-by-step explanation:
If y is inversely proportional to x, we can say that x1 : x2 = y2 : y1
The order of y2 and y1 respectively are interchanged as y is inversely proportional to x
Now let us simply substitute our known values, and solve for x2;
x1 : x2 = y2 : y1
20 : x2 = 12 : 3
20/x2 = 12/3
12(x2) = 3(20)
12(x2) = 60
x2 = 60/12 = 5
a coach bought three soccer balls on sale. they normally sell for $26 each. they were on sale for $7 off the original price. the total tax on the ball was $4 . the expression represents the total amount paid. Then explain how to use the order of operations to find the total amount the coach paid for the soccer balls.
Answer:
The coach paid $69 on the three soccer balls
Step-by-step explanation:
If the coach bought 3 soccer balls for 26$, minus the $7 on each, plus the $4 tax on each, the expression would be:
3 × (26 - 7 + 4)
We put the addition and subtraction in parentheses because of PEMDAS. PEMDAS say we must solve for whatever is in the parentheses first, then exponents (there are none in the expression), ans then multiplication. If those numbers were not in parentheses, the answer would look completely different as we would multiply before subtracting and adding. We must find the total amount each ball cost first:
26 - 7 + 4 = 23
Each ball cost $23
If the coach bought 3 balls for $23 each, we have to multiply the two numbers:
3 × $23
$69

Evaluate the expression below using the properties of operations. Show your steps to receive full credit. −36 ÷ 14 ⋅ (−18) ⋅ (−3) ÷ 6
Answer:
(-162)/7 or -23 1/7 as a mixed fraction
Step-by-step explanation:
Simplify the following:
(-36)/14 (-18) (-3)/6
Hint: | Express (-36)/14 (-18) (-3)/6 as a single fraction.
(-36)/14 (-18) (-3)/6 = (-36 (-18) (-3))/(14×6):
(-36 (-18) (-3))/(14×6)
Hint: | In (-36 (-18) (-3))/(14×6), divide -18 in the numerator by 6 in the denominator.
(-18)/6 = (6 (-3))/6 = -3:
(-36-3 (-3))/14
Hint: | In (-36 (-3) (-3))/14, the numbers -36 in the numerator and 14 in the denominator have gcd greater than one.
The gcd of -36 and 14 is 2, so (-36 (-3) (-3))/14 = ((2 (-18)) (-3) (-3))/(2×7) = 2/2×(-18 (-3) (-3))/7 = (-18 (-3) (-3))/7:
(-18 (-3) (-3))/7
Hint: | Multiply -18 and -3 together.
-18 (-3) = 54:
(54 (-3))/7
Hint: | Multiply 54 and -3 together.
54 (-3) = -162:
Answer: (-162)/7
Sharon has a cake she wants to share with her friends. If she gave 2/5 to Sam and 1/5 to mary. How much does she have left for herself?
Answer:
2/5 of the cake
Step-by-step explanation:
First, find how much she gave away:
2/5 + 1/5
= 3/5
Then, to find how much she has left, subtract 3/5 from 1
1 - 3/5
= 2/5
So, she has 2/5 of the cake left for herself
Why does the range of this function include negative values? What is the significance of the point where the graph crosses the horizontal axis
Answer:
Because the graph does not include any negative values for the range, the range is only nonnegative real numbers. Cubic function f(x)- x^3.
Suppose y varies directly as x, and y = 21 when x = 3. Find x when y = 42.
Answer:
x = 24
Step-by-step explanation:
y₂ - y₁
42 - 21 = 21
x + 21
3 + 21 = 24
So when y increases by 21, so does x.
x = 24
Ian bought a package of gummy bears that contains 4 cups. if he eats 2/3 cup everyday, how many days of candy does he have?
Answer:
6 days
Step-by-step explanation
2/3 cups x 3 days = 2 cups
2 cups x 2 cups = 4 cups
4 cups = 6 days
Answer:
6
Step-by-step explanation:
1) Get 4 and divide it by 2/3
2) To do this you put the inverse which is 4/1 x 3/2
3) Cross divide, then multiply.
4) (4/1 x 3/2) so 4/2 = 2 which is 2 (and whatever you do to one side, you have to do to the other side) so 2/2 is 1. Then 3/1 = 3 and 1/1 = 1 so it stays same. So now the equation becomes 2/1 x 3/1
5) This means the ones cancel out since in math ones don't have to be seen even though they are there.
6) 2 x 3 = 6
So you get 6

Identify the odd function.
A) f(x) = 5
B) f(x) = 8x
C) f(x) = |x3|
D) f(x) = x2 + 7
Answer:
Step-by-step explanation:
odd functions are those function in which
-f(x) = f(−x)
if the function is odd , the graph of function is symmetrical about origin.
_________________________________________________
In the given problem
option B is correct answer
B) f(x) = 8x
replacing x with -x to satisfy the above described condition
f(-x) = 8(-x) = -8x
as we know 8x is equal to f(x)
f(-x) = -8x = -f(x)
hence,
f(-x) = -f(x)
hence, option B is correct answer.

8n + 8 =-56 its a two step equating help please
Answer:
n = -8
Step-by-step explanation:
Original Equation:
8n + 8 = -56
Subtract 8 from boths sides.
8n = -64
Divide both sides by 8
n = -8
Hope this helped :)
Please consider Brainliest :)
Step-by-step explanation:
its -8
8n + 8 = 56
8n + 8 - 8 = 56 - 8
8=−64
8n/ 8 -= -64
8n / 8 = -64 / 8
simplified = n = - 8
n equals -8
