In a photograph, a stadium measures 7 inches across by 2 inches high. If the actual stadium measures 1000 feet across, which equation can be used to find x, the height of the stadium in feet? 1000 + 7 = x + 2
x/1000 = 2/7
1000 - x = 7 - 2
1000/x = 2/7

When a rectangle is dilated, how do the perimeter and area of the rectangle change?

If f(x) = 4x – 3 and g(x) = 8x + 2, find each function value a.f[g(3)] b.g[f(5)] c.g{f[g(-4)]}

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
