Answer:
x={-13,-2}
Step-by-step explanation:
(x+13)(x+2)=0
x+13=0
x=-13
x+2=0
x=-2
x={-13,-2}
He can use addition by adding 0.44 and 1.224 together to see how much Vitamin B-12 (so far he has 1.664 in all.) he has right now. then he needs to subtract that amount (1.664) of B-12 he has from the amount of vitamin B-12 (2.4) he needs. That'll be 0.736 of vitamin B-12 he needs to reach the amount of B-12 he needs.
Answer:
$ 850
Step-by-step explanation:
Martha and her brother started their own car-washing business.
We need to use front-end estimation to find out about how much their business will earn in 5 weeks.
Amount charged per car = $8.50
Number of cars washed per weekend = 22
Therefore, amount earned per weekend = Amount charged per car × Number of cars washed per weekend = 8.50 × 22 = $ 187
Amount earned in 5 weeks = amount earned per weekend × 5 = 187 × 5 = $ 935
Therefore, their business will earn $ 935 in 5 weeks.
The equations has the form:
c=mt, where m is the constant of proportionality
If we isolate m in the equation above:
c=mt
c/t=mt/t
c/t=m
m=c/t
m is c divided by t
If we take the values of the table, and divide c by its correspondent t, we get:
m=c/t=25.50/3=34.00/4=42.50/5=51.00/6=59.50/7→m=8.5
Then: c=8.5t
Answer: The equation that represents the proportional relationship in the table is: Second option
