Answer:
10c ≥ 150
At least 15 cars (or c ≥ 15)
Step-by-step explanation:
If she gets $10 for every car she washes a car then 10c is the rate of her gaining money and she needs at least (greater than or equal to) $150.
This equation can be used to express the situation:
10c ≥ 150
<em>To solve you divide the 10 from both sides of the inequality to get.</em>
c ≥ 15

Answer:
The ratios are equivalent.
Step-by-step explanation:
If you multiply both 5 and 6, the ratio stays the same.
5:6 = 10:12 = 15:18 = 20:24 etc.
You can try this by dividing the larger number by the smaller number. You'll always get 1.2 as the "relationship", or ratio, is preserved.
24/20 = 1.2
15/18 = 1.2
10/12 = 1.2
6/5 = 1.2
Answer:
C & D
Step-by-step explanation:
x² + 3x - 3 = 0
a = co efficient of x² = 1
b= co efficient of x = 3
c = constant = -3
roots = (-b ± 
)/2a
= (-3±![\sqrt{3^{2}-4*1*[-3]}](https://tex.z-dn.net/?f=%5Csqrt%7B3%5E%7B2%7D-4%2A1%2A%5B-3%5D%7D)
)/2*1
= (-3±
)/2
= (-3±√21)/2
