Answer:
x=1.818minutes
Step-by-step explanation:
3/60 miles per minute for walk
8/60 miles per minute for run
0.05x + 0.1333y=1
x+y=10
x=y-10
0.05(y-10) + 0.133333y = 1
0.05y-0.5+0.133333y=1
0.18333y=1.5
y=8.18minutes
x=10-8.18
x=1.818minutes
Answer: 54
Step-by-step explanation:
Answer:
You should buy from the first store
Step-by-step explanation:
Since there are 4 quarts in a gallon, we will need to multiply .80 by 8 to figure out how much it costs for 2 gallons. This will be $6.40 for the second store, and in order to find out how many the first store offers, we multiply 3 by two, which is six.
So, the first store charges $6.00 for two gallons, and the second store does $6.40 for two gallons of milk
Complementary angles add up to 90 degrees. Therefore, the answer is c. 18 + 72 = 90
Hi there!
Begin by distributing the 5:
5(2x) + 5(-12) = -90
Simplify:
10x - 60 = -90
Add 60 to both sides:
10x = -90 + 60
10x = -30
Divide both sides by 10:
x = -3
