Answer:
-1 =v
Step-by-step explanation:
3 = -2v − v
Combine like terms
3 = -3v
Divide each side by -3
3/-3 = -3v/-3
-1 =v
Answer:
In 180 days the three of them will do their laundry again on the same day.
Step-by-step explanation:
we need to find the least common factor or 9, 10 and 12:
LCM(9, 10, 12) = 180
The distance? If it is asking for the distance then its square root 313.
Answer:
y=$2.95x+$479.4
Step-by-step explanation:
Let
x----> the number of movie rentals
y ----> the cost for movie rentals
we know that
The expression that represent the monthly cost is equal to
y=$2.95x+$39.95
1 year has 12 months
so
The expression that represent the yearly cost is equal to
y=$2.95x+$39.95*(12)
y=$2.95x+$479.4
We know by definition that complementary angles add up to 90 degrees. We can set up an equation using the ration given:
17x+13x=90, with x representing the amount you need to multiply the ratio by to get 90.
17x+13x=90
30x=90
x=3
We now know that the number we multiply the ratio by is 3. The smaller number in the ratio is 13, and so therefore we multiply it by 3.
3*13=39
The answer is 39 degrees.
