The work inside parentheses cannot be carried out as shown, so the next approach to consider is multiplying the expressions inside the parentheses by -5 and 5 respectively:
-5 + 25x - 40x - 10 = -4x - 8x (Are you sure it's really "-4x - 8x"?)
Combining the x-terms:
-5 - 15x - 10 = -12x
Combining all like terms: -15 = 3x, so that x = -5 (answer)

Answer:
40 problems in 100 minutes
Step-by-step explanation:
This is a ratio problem.
You first divide 30 minutes by three to get how many problems she can do in 10 minutes. What you do to one side you do to the other side. So then, you should have 4 problems in 10 minute. Then, you multiply 10 by 10 and 4 by 10 to get 40 problems in 100 minutes.
Answer:
The answer is 24.
Step-by-step explanation:
from 0 to 50 there are 12 numbers that are a multiple of 4 now we convert the 12 and 50 into a fraction it would look like this:
12/50
then we need to find the least common denominator of 50 and 100, it is 100 so we multiply 50 and 12 times 2 to get an answer of 24/100.
