1.5
Explanation: 3 is total. You have two stars. 1.5+1.5=3
A. The amount of money she must earn in the summer must be
x ≥ 2450
B. The inequality that describes the situation is
30x ≤ 2000
C. Solving the inequality
x ≤ 66.67 ~ 66 weeks
D. The answer is Part C means that she can only make use of the $2000 money for food for 66 weeks before it's not enough.
Answer:
(x-1) is factor of our function.
Step-by-step explanation:
We are given a function 
and we are asked to find the correct factor from the given options.
Let us factor out our polynomial.
Therefore, (x-1) is correct choice for factor of our polynomial.
ITS IS 8x-7y-5z=15 I THINK'

Answer: x = 140 (choice C)</h3>
========================================================
Explanation:
Focus on the upper semicircle. It's composed of the arc pieces that are 30 degrees, x degrees, and y degrees. The y is the missing unmarked portion of the upper semicircle.
Subtract the 30 and y degree angles, divide by 2, and set that result equal to 10. This will help us solve for y
(30-y)/2 = 10
30-y = 10*2
30-y = 20
-y = 20-30
-y = -10
y = 10
Because the 30, x and y arcs form a semicircle, this must mean the three arcs add to 180 degrees
30+x+y = 180
30+x+10 = 180
x+40 = 180
x = 180-40
x = 140
