3x + 7y = 2 6x-5y=4 solve this by elimination method
Answer:
x=2/3, y=0
Step-by-step explanation:
3x + 7y = 2,
6x - 5y = 4
Make the x coefficient the same in both equations.
3x + 7y = 2
(whole thing multiplied by 2)
6x + 14y = 4
Now subtract the equations to eliminate the x variable.
6x + 14y = 4
-(6x - 5y = 4)
19y = 0
y = 0
Substitute 0 for y in one of the equations.
3x + 7(0) = 2
3x = 2
x = 2/3

Answer:
x = 30
y = 7
Step-by-step explanation:
The triangle given is an equilateral triangle.
Equilateral Triangle
A triangle that has same length of all sides of triangle. They have same congruent internal angles as well.
So, If length of one side = 7
Length of other two sides will also be same i,e 7
Length of 2nd side = 7
Length of 3rd side = 7
Now, finding angles and value of x
The one angle is 2x, so the other two angles will be also 2x (because all angles of equilateral triangle are same)
We know that sum of all sides of angles of triagle = 180
We can write: [tex]2x+2x+2x=180[/tex]
Solving the equation to find x
[tex]2x+2x+2x=180\\6x=180\\x=180/6\\x=30[/tex]
So, x = 30
Since y is not given in picture, I think it is length of other sides i.e y = 7
simplify
[tex] \sqrt{ - 3} \sqrt{ - 12} [/tex]
please help me I've been stuck on this for ever

Step-by-step explanation:
the square root of any negative value results in an imaginary number, 'i'
so, [tex]\sqrt{-3}[/tex] = 3i and [tex]\sqrt{-12}[/tex] is 12i
'i' is equal to -1
3(-1) x 12(-1) = 36

if the cost of a book is RS.480, find the cost of 4 books
Step-by-step explanation:
for 1 book=480
for 4 books= 480×4
=1920
Answer:
If one book costs 480, then four books will cost the quadruplee. To calculate it, we can multiply by 4 the price of one book:
480 * 4 = 1920
So we know it wouldd cost 1920 rp to buy four.
Cindy works in a cake shop and earns $42 per day. She earns an extra $4 for each cake she sells. If Cindy wants to earn at least $50 per day, which inequality shows the minimum number of cakes, n, that she should sell?
42 + 4n ≤ 50, so n ≤ 2
42 + 4n ≥ 50, so n ≥ 4
42 + 4n ≥ 50, so n ≥ 2
42 + 4n ≤ 50, so n ≤ 4
Answer:
Step-by-step explanation:
42+4n<50, so n<4
Answer:
42+4n ≥ 50, so n ≥ 2

A slow boat to china travels at a constant speed of 17.25 miles per hour for 200 hours. how far was the voyage?
Answer:
3450 miles
Step-by-step explanation:
Multiply the number 17.25 by 200 since the boat is traveling for 200 hours and each hour is 17.25 miles to get 3450 miles which is your answer.
Answer:
[tex]\boxed {\boxed {\sf 3,450 \ miles}}[/tex]
Step-by-step explanation:
Distance can be found by multiply the speed by the time.
[tex]d=st[/tex]
Where d is the distance, s is the speed, and t is the time.
1. Define Variables
The speed is 17.25 miles per hour and the time is 200 hours.
[tex]s= 17.25 \ mi/hr[/tex]
[tex]t= 200 \ hr[/tex]
2. Calculate Speed
Substitute the values into the formula.
[tex]d=17.25 \ mi/hr * 200 \ hr[/tex]
Multiply. The hours (hr) will cancel each other out and leave miles as the units.
[tex]d=17.25 \ mi *200\\[/tex]
[tex]d=3450 \ mi[/tex]
The voyage was 3,450 miles

If r/s = 22 and the value of r is 242, what is the value of s
Answer:
s = 11
Step-by-step explanation:
Given
[tex]\frac{r}{s}[/tex] = 22 ← substitute r = 242
[tex]\frac{242}{s}[/tex] = 22 ( multiply both sides by s )
242 = 22s ( divide both sides by 22 )
11 = s

Answer:
Solution is invalid
Step-by-step explanation:
Let the time when they will have the same water content be x hours
At x hours;
For the first tank, the content will be;
50 + 10x
For the second;
29 + 3x
Equating both, will give us x
29 + 3x = 50 + 10x
We will get x as a negative number here
Since number of hours can not be negative, the solution is invalid

So when finding a number in a percent you wanna see how much that percent will go into that number. So like if I said how many times does 60% go into 200 you would have to see how many times the number 200 would go into 60%. does this make sense? If so this is how you can find your answer.

Please, Its due soon! WILL GIVE BRAINLIEST IF CORRECT
Answer:
Haven't done this in years, but I think that's correct.
Step-by-step explanation:
63.7 x 10^1 = 637
94.6 x 10^3 = 94600
0.365 x 10^4 = 3650
Answer:
The answer to the first question is 637
The answer to the second question is 94600
The answer to the third question is 3650
Step-by-step explanation:
63.7 x 10 = 637
94.6 x 10^3 = 94.6 x 1000 = 94600
0.365 x 10^4 = 0.365 x 10000 = 3650

Determine whether the inverse of f(x)=2x2−5
is a function. Then find the inverse.
Answer:
Not a function. The inverse is
[tex]y = \sqrt{ \frac{x + 5}{2} } [/tex]
and
[tex]y = - \sqrt{ \frac{x + 5}{2} } [/tex]
Step-by-step explanation:
Any even-degree polynomial functions that are inverted will not be a function.
[tex]f(x) = 2 {x}^{2} - 5[/tex]
Let y = f(x)
[tex] y = 2 {x}^{2} - 5[/tex]
To proceed the inverse, swap the x-term and y-term.
[tex]x = 2 {y}^{2} - 5[/tex]
Convert into function form.
[tex]x + 5 = 2 {y}^{2} \\ 2 {y}^{2} = x + 5 \\ {y}^{2} = \frac{x +5 }{2} [/tex]
The reason why inverted even-degree polynomial function cannot be a function because the inverse graph doesn't pass line test.
Thus the answer is
[tex]y = \sqrt{ \frac{x + 5}{2} } \\ y = - \sqrt{ \frac{x + 5}{2} } [/tex]

Please help me I’m so confused
Answer:
60
Step-by-step explanation
Okay, uh... this is gonna be confusing to explain.
So a hexagon's angles add up to 720. This means, we can find each angle's supplementary angle by subtracting each value we know away from the total.
So, we know the inside angle of angle 6 is 90.
So: 720-90=630
Now, typically, you would divide by the remaining angles, but we have basically 2 angles of different values since 1, 2, and 3 are equal, and 4 and 5 are equal.
However, we know that 1, 2, and 3 are 10 degrees less than 4 and 5. So if we "add" 10 degrees to each of those angles we get:
10*3=30
630-30=600
Now we made it as though each angle (1-5) is equal. So now we divide by 5.
600/5=120
This means the supplementary of angles 4 and 5 is 120, so we subtract that value from 180 since a straight angle is 180.
180-120=60
Now, to check this we reverse it.
(120*2)+(120*3)+(10*3)+(90)=
240+360+30+90=
600+30+90=
600+120=
720.
Um... I think this is it?? Your school is scary :o
