Step-by-step explanation:
15x3/4=45/4=11.25pounds
So you basically add the amount it grew each week. So week one is 2 and 1/2, week two is 2 and 3/4 and week three is 3 and 1/4. to make things simpler, add week two and three which gets you 6inches, then add week one, to get 8 and a half inches.
Answer:
<h3>y = 35x</h3>
Step-by-step explanation:
If you notice, point 4 on the x-axis (horizontal) coincides with 140 on the y-axis.
If you multiply x * 35 = 140
x is four.
Answer:
x = 150 miles
Cost = $100
Step-by-step explanation:
Company A = 50 + 20 + 0.20x
= 70 + 0.20x
Company B = 55 + 0.30x
Where,
x =number of miles
find the number of miles for which the companies charge will be the same
Equate the charges of both companies
70 + 0.20x = 55 + 0.30x
70 - 55 = 0.30x - 0.20x
15 = 0.10x
Divide both sides by 0.10
x = 15 / 0.10
= 150
x = 150 miles
The number of miles for which the companies charge will be the same is 150 miles
Substitute 150 miles into any of the companies charges to find the charge
Company B = 55 + 0.30x
= 55 + 0.30(150)
= 55 + 45
= $100
