D. (xy2 + 3z14)(x2y4 – 3xy2z14 + 9z28
Hello!
7 out of 11 people brought an umbrella to the beach
this is a fraction of 7/11
We multiply this by 99 to get how many people brought an umbrella out of 99
7/11 * 99 = 63
You subtract this from 99 to see how many did not have an umbrella
99 - 63 = 36
The answer is 36 people
Hope this helps!
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.
