Answer: 42 - 8x
Step-by-step explanation:
Here is the complete question:
Jessica had $15. She bought 3 apples for x dollars each. Levi had $27 and bought 5 apples for x dollars each. Which expression represents how much money both Jessica and Levi have left altogether?
Select one:
27 – 5x
42 – 8x
12 – 2x
39 – 3x
From the question, Jessica had $15. She bought 3 apples for x dollars each. This means she had:
15 - (3 × x) = 15 - 3x
Levi had $27 and bought 5 apples for x dollars each. Levi will have:
27 - (5 × x) = 27 - 5x
The amount they'll have altogether will be the addition of their amount left. This will be:
15 - 3x + 27 - 5x
= 15 + 27 - 3x - 5x
= 42 - 8x
All you have to do is divide 3.5 by 5 and you should get 0.7. So she used 0.7 yards on one dress. Hope this helped :)
Because the discriminant is less than zero, there are no real solutions in the equation.
Answer: The y-intercept should be the $20. The equation would be y=10x+20. Not sure if that’s what you’re asking.

Answer:
The measure of angle JKP is 
Step-by-step explanation:
step 1
we know that
The measure of the arc is equal to the measure of its central angle
so
and
step 2
Find the measure of the angle JKP
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.
substitute the values
