Answer: yes, she can
Step-by-step explanation:
10:13 (ratio) = 0.769
3 (pounds) x 0.769 (ratio) = 2.307 (dollars)
5 (hours) x 2.307 (dollars) = 11.35
Answer:
$75.25
Step-by-step explanation:
x will be how much money chris needs to raise. set up the problem like this:
= 
cross multiply: 100x = 7525
divide each side by 100: x = 75.25
Answer:
- Define your variable and write your equation: 36 + b + (3b-28) = 180°.
- measure of the second angle: 43°.
- measure of the third angle: 101°
Step-by-step explanation:
a = 36
c = 3b - 28
a + b + c = 180°
a = measure of the first angle
b = measure of the second angle
c = measure of the third angle
then:
1) 36 + b + (3b-28) = 180 ⇒ )Define your variable. Write your equation and solve)
b + 3b + 36 - 28 = 180
4b + 8 = 180
4b = 180 - 8
4b = 172
b = 172/4
2) b = 43° ⇒ measure of the second angle
c = 3b - 28
c = 3*43 - 28
c = 129 - 28
3) c = 101° ⇒ measure of the third angle
Check:
36° + 43° + 101° = 180°
Answer: x ≤ 5
Step-by-step explanation:
1.5(x-5) ≤ 15
x-5 ≤ 15/1.5 15/1.5 = 150/15 = 10
Therefore:
x-5 ≤ 10
x ≤ 10 - 5
x ≤ 5
