For clarification, I will put how Ive interpreted this equation:
![8x-2x+2= \frac{1}{3}(9x+3)+7](https://tex.z-dn.net/?f=8x-2x%2B2%3D%20%5Cfrac%7B1%7D%7B3%7D%289x%2B3%29%2B7%20)
This can be solved by simplifying and rearranging:
Answer:
Maria earns 100 dollars
E=100
Step-by-step explanation:
if E=20h and they want to know how much Maria will make in 5 hours substitute the h for 5. 20 x 5 =100
E=100
Answer:
20
Step-by-step explanation:
If lines m and n are parallel, then the labelled angles would be considered alternate exterior angles. By definition, such angles are of the same value.
Thus, we set the two expressions of 4x - 23 and 2x + 17 equal:
4x - 23 = 2x + 17
Subtract 2x from both sides and add 23 to both sides:
2x = 23 + 17 = 40
Divide by 2:
x = 40/2 = 20
The answer is thus 20.

The given data are:
70% of single-vehicle traffic fatalities that occur at night on weekends involve an intoxicated driver. If a random sample of 15 single-vehicle traffic fatalities that occur at night on a weekend is selected, the probability that 11 involve a driver who is intoxicated is:
(11/15) * 0.70 = 0.513
W^2 + 7w - 144
you need 2 numbers whose product is -144 and whose sum is +7
that is 16 * -9
so the factors are
(w + 16)(w - 9)
