The first thing you would do is square 17,000, which is 298,000,000. Then you would multiply 298,000,000 by 0.10. (or divide the number by 10)
This would get you 28,900,000.
Each student should make at least $25 to reach their goal.
The base of the middle triangle is 3 and the base of the larger one is 6, so the larger triangle is twice the size of the middle one.
Multiply the height of the middle one by 2 to get the height of the larger one, which is labeled n.
n = 5 x 2 = 10
I will assume a + sign between the x and 5.3:
x+5.3 = -1.2
To get the x alone we need to subtract 5.3 on both sides, like this:
x+5.3-5.3 = -1.2 - 5.3
x = - 6.5
a is the correct answer.
