Solve the equations 2x + 2 = x + 9
Answer:
x=7
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
Given
2x + 2 = x + 9 ( subtract x from both sides )
x + 2 = 9 ( subtract 2 from both sides )
x = 7

Number 4!!What is the cost of 80cm of copper pipe at €2 a metre?
Answer:
$1.6
Step-by-step explanation:
We need to find the cost of 80 cm of copper pipe at $2 a metre.
Cost of 1 metre = $2
80 cm = 0.8 m
It means,
0.8 m = $2 × 0.8
= $1.6
So, the cost of 80 cm of copper pipe is equal to $1.6.
Find the value of each variable round your answer to the nearest 10th
Answer:
10 for x and y
Step-by-step explanation:
Because the triangle adds up to 30 deggrees
So... you want to take 4 out.
30- 4 = 24
Than...You want to divided 24 by 2.
And that equals 12
Than round 12's by tenth
Which equals 10

Solve each problem. Round to the nearest tenth if necessary. Use 3.14 for π. What is the radius of a circle with a circumference of 15 cm? Show your work! I will be giving out brainliest!
Answer:
2.3
Step-by-step explanation:
First off, you start with the circumference formula which is 2(pi)r. Since we know our circumference, we can create the equation solving for r. so we have 15=2(pi)r. Now in order to solve for r, we need to transfer everything to the other side, meaning dividing by 2(pi). So 15/2(pi)=2(pi)r/2(pi). Since we are using 3.14 for pi, 3.14*2 is 6.28. 15/6.28 which is about 2.388 So the radius of the circle is 2.3 (rounded to the nearest tenth)

each of equal sides of an isosceles triangle is 4cm greater than its height .If the base of triangle is 24 cm ,calculate the perimeter and the area of the triangle
192 cm²
Step by step explanation :-Let us take the height be x , then its side = x + 4. Now half of base will be 12 cm .
According to Pythagoras Theorem :-
=> base² + perpendicular ² = hypontenuse ²
=> 12² + x² = (x+4)²
=> 144 + x² = x² + 16 + 8x
=> 8x = 144-16
=> 8x = 128
=> x = 128/8
=> x = 16 cm .
Hence the height of ∆ is 16 cm .So the area will be half the product of base and altitude.
= 1/2 * 16 cm * 24cm .
= 192 cm²
★ Hence the area of the triangle is 192 cm² .Explain Combined Mean.
Answer:
A combined mean is simply a weighted mean, where the weights are the size of each group. For more than two groups: Add the means of each group—each weighted by the number of individuals or data points, Divide the sum from Step 1 by the sum total of all individuals (or data points).

EFGH is translated 5 unite to the left and 2 units up.
What the coordinates of E'?
A. E' (6,-6)
B. E'(-1,1)
C. E'(-1,-3)
D. E' (9,-3)
Answer:
B. E'(-1,1)
Step-by-step explanation:
Change the X value of each of the points by -5, as this represents 5 units left.
Change the Y value of each of the points by +2, as this represents 2 units up.
For E:
X: 4 - 5 = -1
Y: -1 + 2 = 1
Coordinate: (-1,1)
8th grade math, please help.
Answer:
x=72 degrees
Step-by-step explanation:
180-108=72
it is 180 because a straight angle is 180 degrees.
then you subtract 108, which is an alternate interior angle, to get 72, which is an alternate exterior angle.
Answer:
x=72
Step-by-step explanation:
Since the whole angle is 180 you have to do 180-108 which you get 72.
Then since x and 72 are vertical angles they have to be the same so x=72

f(x) = x2 – x + 11
g(x) = -x – 4
Find: (gof)(x)
Answer:
g(f(x)) = -x^2 + x - 15
Step-by-step explanation:
g(f(x^2 - x + 11) = -1 * (x^2 - x + 11) - 4 = -x^2 + x - 11 - 4 = -x^2 + x - 15
