Answer:
Option B. (0.7)n = 45.50
Step-by-step explanation:
If n represents the number of dollars she raised this year then as per question the equation will be (7/10)n = 45.50
(0.7)n = 45.50
Therefore option B. 45.50 = 0.7n is the answer.
B. -5
The two straight lines are parallel, and the angles are at the same places (below and to the right of the diagonal line). The two angles must be the same, and to get 65 from x + 70, x has to be -5.
Answer:
A
Step-by-step explanation:
Solving for x:
-3x + 8 ≥ 14
-3x ≥ 6
x ≤ -2
Notice the sign gets reversed when you divide or multiply by a negative number.
The only option less than -2 is -3, A.
Here's a tip: on multiple choice questions, sometimes it's faster to try each answer instead of solving the equation. This can save time on tests like the SAT or ACT.
Let's try it:
-3(-3) + 8 = 9 + 8 = 17
-3(-1) + 8 = 3 + 8 = 11
-3(0) + 8 = 0 + 8 = 8
-3(3) + 8 = -9 + 8 = -1
So you can see the answer is A.
