Marta made 4 stacks of wooden blocks. the first stack was 4 blocks tall. the second stack was 7 blocks taller than the first. the third stack was 2 blocks shorter than the second stack, and the last stack was 7 blocks taller than the third stack. how many blocks did marta use in all?

7(x - 2) = 3(x + 4) solve the following equation. then enter your answer in the space provided using mixed number format.

Solve the following simultaneous equation by using an algebraic method (either substitution or elimination) 2x + 3y=-4 4x-y=11

Iwill give brainliest. suppose tommy walks from his home at (0, 0) to the mall at (0, 5), and then walks to a movie theater at (6, 5). after leaving the theater tommy walks to the store at (6, 0) before returning home. if each grid square represents one block, how many blocks does he walk?
