Answer:

The cost of each apple is $0.39

The cost of each orange is $1

Step-by-step explanation:

Lisa buys a dozen apples and two oranges.

Let 'x' be the cost of each apple

and 'y' be the cost of each orange

Lisa buys a dozen apples and two oranges.

12x+2y

Oranges cost $1 each, so y=1

12x+2

Jeremy buys six apples.  So 6x

Total amount spent is $9

12x+2+6x=9

18x+2=9

Subtract 2 from both sides

18x=7

Divide both sides by 18

x=0.39

The cost of each apple is $0.39

The cost of each orange is $1

Find the value of X in the following rectangle if the area is 180 square inches
andrezito [222]
Hello!

You find the area of a rectangle by the equation A = lw

A is area
l is length
w is width

Put in the values you know

180 = 3x * 6

Now you solve it algebraically

Divide both sides by 6

30 = 3x

Divide both sides by 3

10 = x

The answer is 10in

Hope this helps!

Answer:

150 miles

Step-by-step explanation:

let m represent miles

$70 + .70m = $40 + .90m

subtract 40 from each side

$30 + .70m = .90m

subtract .70m from each side

$30 = .20m

divide both sides by .20

150 = m

jason runs 440 yards in 75 seconds. At this rate, how many minutes does it take him to run a mile? (1 mile = 1,760 yards).​
mamaluj [8]

Answer:

5 minutes

Step-by-step explanation:

we know that

Jason runs 440 yards in 75 seconds

using proportion

Find out how many minutes does it take him to run a 1.760 yards (one mile)

\frac{440}{75}=\frac{1,760}{x}\\\\x=1,760(75)/440\\\\x= 300\ sec

Convert seconds to  minutes

Divide by 60

300\ sec=300/60=5\  min
