Answer:
3
Step-by-step explanation:
25=4x+3x
25=7x
25/7=3.5
25=4(3.5)+3(3.5)
25=14+10.5
10.5/3=3.5

Answer:
No solution
Step-by-step explanation:
There are no values of x that make the equation true; hence making it have no solution.

Answer:
Im on the same question so dont copy word for word
Step-by-step explanation:
The first error he made is that he didn't do the right steps in order to find the area of the two triangles. Instead he should have done 0.5 X 16 X 15 X 2= 240
Then the area for the three rectangles should be 16 X 8 + 17 x 8 + 17 X 8 = 400
If you add it all together, the surface area is actually 640 square meters.
Let x = 1. Substitute x = 1 into the equation:
y = -9X(1)+3
y = -9+3
y = -6
-> Ordered pairs are written in the form (x,y). Thus in this case, your ordered pair is (1,-6).
