Answer:
x = 6
Step-by-step explanation:
2x + 7 = 19
-7 -7
2x = 12
*divide both sides by 2*
x = 6
Value of x is x=32
Step-by-step explanation:
We need to find the value of x of the equation 
Solving the equation and finding value of x

Adding 4 on both sides

Divide both sides by 0.5

So, value of x is x=32

2. 2

or 17 since it is less than 17.2
Answer:
a cone with a base circumference of about 126 mm
Step-by-step explanation:
Rotating a triangle about a line results in a cone created by the rotation. This is because the segment at the bottom forms a circle, and the point at the top stays there; the three-dimensional figure with a circular base and a point at the top is a cone.
Since we rotate the segments about a line, this makes the length of the base the radius of the circle. This means the circumference would be
C = 2πr = 2(3.14)(20) = 125.6 ≈ 126 mm
1) Set up an equation for the total, with T representing Trevor and M representing Marissa:
T + M = 26
2) Use the provided information related Marissa's t-shirts to Trevor's to solve for one variable at a time (in this case, T):
M = T-6
3) Substitute M with this equation into the initial, first equation:
T + (T-6) = 26
4) Combine like terms and isolate T:
T+T = 26 + 6
2T = 32
T = 16
5) Therefore, you now know that Trevor has 16 t-shirts. To find the number of t-shirts that Marissa has, simply plug in this amount for T into the equation that was already set up for M:
M = T - 6
M = 16 - 6
M = 10
Therefore, Trevor has 16 t-shirts and Marissa has 10 t-shirts.
