Answer:
2x=4
Step-by-step explanation:
3(2x-5)-4x+8=-2x+1
6x-15-4x+8=-2x+1
2x-15+8=-2x+1
2x-7=-2x+1
4x=8
2x=4
This means that x is equal to -3 and y is equal to 8. For example, if you had f(x)=-3x-1 and plugged -3 into x, you would get the y-value of 8.
Answer: 233.92
Step-by-step explanation:
6.80 times 3 = 20.4
138.52 plus 75.00 plus 20.4 = 233.92
A rhombus diagonals form right angles. The diagonals also cut in half the angles
use cosine: cos38 =
a = 20cos38
a=15.8
Here is the equation you need:
3(x + 9) = 2x - 7
You finish.
