Answer:

b = $423.25

Step-by-step explanation:

cost of car rent per day = $25

Cost of GPS rent per day = $12.95

Cost of gas per gallon= $4.30

A car has 19 gallons and a GPS

The cost of gas for 19 gallons = 4.30 * 19

= $81.70

Total bill = b

Number of days = d

b = (25 + 12.95)d + 4.30*19

b = 37.95d + 81.70

When d = 9 days,

b = 37.95(9) + 81.70

b = 341.55 + 81.70

b = $423.25

Seeds planted in one garden = y vegetable seeds

Seeds planted in another garden =  4y + 7 vegetable seeds

To Find:

The number of seeds Val is going to plant = ?

Solution:

Let the total number of seeds that Val is going to plant be x.

Then

x =  number of seeds planted in garden one +  number of seeds planted in the other garden

Now substitute the values, we get

x = y + (4y+7)

x = 5y + 7

Answer:

square root of 2

Step-by-step explanation:

Sides are 1 and 1 and the hypotenuse is the longest side (opposite the right angle)

We can use pythagerouses theorem : a^2+b^2=c^2

this means that 1^2+1^2=c^2

1+1=c^2

2=c^2

c=2/sqrt

c is the square root of 2

the hypotenuse is the square root of 2
