Please help
Answer: -8.5 or -17/2
Step-by-step explanation: you have to put the info into an equation. product of a number x and 7 is 7x. two less than mean subtracting two and 5 times the difference of x and 3 translates to 5(x-3). Once put into an equation, it'll look like 7x = 5(x-3) - 2. Now solve this equation for x and you'll end up with -8.5 in decimals or -17/2 in fractions.

−5(−x−1)+4x−1= 49 solve for x
Answer:
x = 5
Step-by-step explanation:
Solve for x:
-1 - 5 (-x - 1) + 4 x = 49
-5 (-x - 1) = 5 x + 5:
(5 x + 5) + 4 x - 1 = 49
Grouping like terms, 5 x + 4 x - 1 + 5 = (5 x + 4 x) + (-1 + 5):
((5 x + 4 x) + (-1 + 5)) = 49
5 x + 4 x = 9 x:
9 x + (-1 + 5) = 49
5 - 1 = 4:
9 x + 4 = 49
Subtract 4 from both sides:
9 x + (4 - 4) = 49 - 4
4 - 4 = 0:
9 x = 49 - 4
49 - 4 = 45:
9 x = 45
Divide both sides of 9 x = 45 by 9:
(9 x)/9 = 45/9
9/9 = 1:
x = 45/9
The gcd of 45 and 9 is 9, so 45/9 = (9×5)/(9×1) = 9/9×5 = 5:

Solve −4m + 5 + 2m = 3 – 4m.
Answer:
m= -1
Step-by-step explanation:
-4m+5+2m = 3-4m
=> -4m+2m+4m = 3-5
=> 2m = -2
=> m = -2/2 = -1
Answer:
m = -1
Step-by-step explanation:
-4m + 5 + 2m = 3 - 4m
Add up light terms
-2m + 5 = 3 - 4m
Subtract 3 from both sides.
-2m + 2 = -4m
Add 2 to both sides.
2 = -2m
Divide both by -2
Final Answer: m = -1

Answer:
[tex]\sqrt{29}[/tex]
Step-by-step explanation:
You would use the Pythagorean Theorem: [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
The a and b is the legs and the c is the hypotenuse
So when you fill it in you get [tex]2^{2}[/tex] + [tex]5^{2}[/tex] = [tex]c^{2}[/tex]
continue to solve the equation 4+25= [tex]c^{2}[/tex]
29 = [tex]c^{2}[/tex]
then you would square root it
c = [tex]\sqrt{29}[/tex]
Find the volume and surface area.
Answer: Formula used for pyramid is (V= 1/3 Bh SA: 1/2 P*l+B) Final answer is SA=110.4 V=64
Step-by-step explanation:
P= Perimeter
l= length
B= Base
To find the perimeter you add all the sides of the base. (4+4+4+4)=16
To find the length you can use Pythagorean Theorem which is a(squared) + b(squared) = c(squared) where c is the hypotenuse. [tex]2^{2}[/tex] + [tex]12^{2}[/tex]= [tex]x^{2}[/tex]
4+144=[tex]x^{2}[/tex]
164=[tex]x^{2}[/tex]
[tex]\sqrt{164}[/tex]=x
x=12.8
To find the base it will be l*w (4*4)=16
Then you plug it in the formula for SA which will be
SA=1/2 16*12.8+16
SA=110.4
For Volume, it will be
V=1/3 Bh
V= 1/3 16(12)
V= 64
8. Present age of Rahul and kiran are in the ratio
5:4. The ratio of their ages will be 6:5 after
5 years.Find kiran's present age.
20 years
25 years
30 years
15 years
Answer:
20 years
Step-by-step explanation:
Given the ratio of their ages = 5 : 4 = 5x : 4x ( x is a multiplier )
Then in 5 years
5x + 5 : 4x + 5 = 6 : 5 , that is
[tex]\frac{5x+5}{4x+5}[/tex] = [tex]\frac{6}{5}[/tex] ( cross- multiply )
5(5x + 5) = 6(4x + 5) ← distribute parenthesis on both sides
25x + 25 = 24x + 30 ( subtract 24x from both sides )
x + 25 = 30 ( subtract 25 from both sides )
x = 5
Thus
Kiran's age is 4x = 4 × 5 = 20

Answer:

Step-by-step explanation:
116-98
so sorry if its incorrect
Answer:
34 degrees
Step-by-step explanation:
ahahah okay this is fun
so what you should do here is extend the line that passes through the 116 and 98 degree angle so that it passes the other parallel line.
It makes a triangle doesn't it
One of the angles is supplementary to 98, so 180-98 = 82 degrees.
Another one of the angles is the opposite angle to the supplementary angle of 116 (remember your line-intersecting-parallel-lines angles), therefore 180-116 = 64 degrees
The last angle of that triangle is the opposite to angle 4, and you can find that using the other two angles of the triangle we made earlier, which you get 180-82-64 = 34 degrees

Find the average rate of change for f(x)= x² + 3x - 6 for x₁
: 1 to 2 = 3
The average rate of change for f(x)=3x²-3 from x =1 to x=2 is 6.
What is the average rate of change?
The average rate of change is the rate at which the value of function changed per unit of independent variable over a given interval. Let f(x) be a function and value of x changes from x₁ to x₂ then rate of change of f(x) over the interval (x₁, x₂ ) is
[f(x₂)-f(x₁)]/[x₂-x₁]
Average rate of change = [f(x₂)-f(x₁)]/[x₂-x₁]
Given function is
f(x)=3x²+3x-6
x changes from 1 to 2
Then average rate of change for f(x) is [tex]\frac{f(2)-f(1))}{2-1}[/tex]
[tex]f(2)=2^{2} +3(2)-6=4+6-6\\\\f(2)=4\\f(1)=1^{2}+3(1)-6 =1+3-6\\f(1)=-2[/tex]
Average rate of change for f(x) is
[tex]\frac{f(2)-f(1))}{2-1}=\frac{4-(-2)}{2-1}\\ =\frac{6}{1}[/tex]

Answer:
B = 2
Step-by-step explanation:
I used Desmos to get a visual representation to help.
The equation y = 4x + 6 has a y - intercept at (6,0).
The equation y = 4x + 2 has a y - intercept at (2,0) and passes through (1,6).

The value of B = 2 when a line, y=mx+b, passes through the point (1, 6) and is parallel to y=4x+6.
What is an equation?
The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.
The equation y = 4x + 6 has a y - intercept at (6,0).
The equation y = 4x + 2 has a y - intercept at (2,0) and passes through (1,6).

A ∠A and ∠ B ∠B are supplementary angles. If m ∠ A = ( 8 x + 6 ) ∘ ∠A=(8x+6) ∘ and m ∠ B = ( 7 x + 24 ) ∘ ∠B=(7x+24) ∘ , then find the measure of ∠ B ∠B.
Answer:
< B = 94
Step-by-step explanation:
Remark
You should edit the question. The way you wrote it, , it looks like you have to square two binomials. That isn't the way it is given I don't think. You are told that A and B are supplementary. That means
A+B = 180
Equation
(8x + 6) + (7x + 24) = 180 Remove the brackets
Solution
8x + 6 + 7x + 24 = 180 Collect like terms
15x + 30 = 180 Subtract 30 from both sides
15x = 180 - 30
15x = 150 Divide by 15
x = 150 / 15
x = 10
Answer
What you need is <B
<B = 7x + 24
<B = 7*10 + 24
<B = 70 + 24
<B = 94
state whether each expression is meaningful. if not, explain why. if so, state whether it is a vector or a scalar.
The dot product of two vectors gives scalar quantity and between scalar quantity, we can not apply any product so options (b), (d), and (e) are not meaningful.
What is a vector?An item with both magnitude and direction is referred to be a vector.
A vector can be visualized geometrically as a straight spline, with a pointing in the orientation and a length equal to the value of the vector.
A line with an arrow in its direction can also be used to represent a vector, and the length of the line relates to the vector's amplitude.
The dot product of two vectors gives scalar quantity while the cross product gives a vector quantity.
Now,
In option (B) ;
a Х (b . c) now here b . c is a scalar quantity and we can not cross multiply a scalar with a vector.
In option (D) ;
(a.b) Χ (c.d) where we cannot multiply two scalars by cross product.
In option (E);
a.(b.c) we can not multiply two scalars by the dot product.
Hence "The dot product of two vectors gives scalar quantity and between scalar quantity, we can not apply any product".

Probability:
Probability refers the possibility of occurring a particular event.
Binomial Probability:
Binomial probability refers the probability of a SUCCESS or FAILURE outcome in an experiment or survey that is repeated multiple times. The binomial is a type of distribution that has two possible outcomes.
The formula for the binomial probability is,
Pₓ = ⁿCₓ pˣ qⁿ⁻ˣ
Where,
n = the number of experiments
x = 0, 1, 2, 3, 4, …
p = Probability of success in a single experiment
q = Probability of failure in a single experiment
Given,
Robert likes chocolate milk, so he decides to visit the milk bottling plant every day for a week to get the free samples.
Unfortunately for him, the bottling plant sometimes bottles regular milk instead of chocolate milk, so each day the plant has a 2/3 chance of bottling chocolate milk.
Here we need to find the probability that the bottling plant bottles chocolate milk exactly 4 of the 5 days he visits.
Apply the values on the formula,
Then we get,
=> Pₓ=⁵C₄ x (2/3)⁴ x (1/3)
=> Pₓ = 5 x (16/81) x (1/3)
=> Pₓ = 80 / 243
