Answer:
B. -1
Step-by-step explanation:
STEP 1: Simplify 3x+2(x−9).
STEP 2: Add 8x and x.
STEP 3: Move all terms containing x to the left side of the equation.
STEP 3: Move all terms not containing x to the right side of the equation.
STEP 4: Divide each term by −4 and simplify.
Answer:
The first one and the second one
Step-by-step explanation:
Answer:
$208
Step-by-step explanation:
Jack has two jobs
The first one, he works at a gas station where he earns $11/hr, he works for 8 hours in a week
= 11×8
= 88
The second one he earns $120/week for walking dogs
Therefore the total money Jack earns in a week can be calculated as follows
= 120+88
= 208
Hene jack earns $208 in a week
Each girl started with 15 dollars.
4$ is the ending amount
x= the amount of money each girl received
4= 2x - 2(13)
Since there were two girls who both received x amount of money, x is multiplied by two. Since both the girls spent 13 dolars on lunch, their original amount is subtracted by 13 times two, since there are two lunches being bought. The end amount of money is four.
to solve:
4= 2x - 2(13)
4= 2x - 26 Simplify by combining like terms
30= 2x Isolate the variable by adding 26 to both sides
15=x Continue to isolate the variable by dividing both sides by two
Each girl started with 15 dolars. Each girl spent thirteen dolars on lunch and had two dolars left over. Each girls' two dolars left over adds up to four dollars.
This problem asks, as simply put, the value of the function at x=3. So, plug in three to find your answer:
2(3) + 1 = 7, so g(3) is 7
