Answer:
y = 40
Step-by-step explanation:
For #7, we are told that y = 10 when x = 2
We are also told that 'y varies directly as x'. That means there is some constant number, k, so that
Formula --> y = kx
Since y=10 and x= 2, we substitute those numbers into the formula.
We get 10 = k × 2.
So k has to be 5, right?
k = 5
So what is y when x = 8?
Use the formula.
y=kx ---> That gives us y = k × 8. But we know k is 5.
So y = 5 × 8 = 40
y = 40
Mia's balance is at -85, which means she had $0,
and has spent $85.
This means that she needs to pay BACK $85, (+85)
and there might be an extra charge since she overspent on her account.
Answer:
5 yards = 15 feet = 180 inches
Step-by-step explanation:
180 inches plus 18 inches = 198 inches
198 x 3 = 594 inches
594 inches = 49 feet 6 inches = 16 yards 1 foot 6 inches, or 16 yards 18 inches
X=32 because both equations are equal to 180 degrees (3x+22°+x+30°=180) just solve that equation and you’ll get your answer
