7 0

Answer:

x>  -7/3y -7

Step-by-step explanation: -7y-3x<21

Step 1: Add 7y to both sides.

−3x−7y+7y<21+7y

−3x<7y+21

Step 2: Divide both sides by -3.

-3x/-3 < 7y+21/-3

x>-7/3y -7

slamgirl [31]

Answer:

That is true. More information below.

Step-by-step explanation:

The perimeter of a rectangle is 86cm. Its shortest side has a length of 16cm. State the length of the longest side.
Artyom0805 [142]

Answer: length = 27 cm

Perimeter = 2(l + w)

86 = 2l + 32

86 - 32 = 2l

l = 54/2 = 27 cm.

Michelle borrows a total of $2500 in student loans from two lenders. One charges 4.4% simple interest and the other charges
Inessa [10]

The amount borrowed from the  the lender that charges 4.4% interest is $1000.

The amount borrowed from the  the lender that charges 5.7% interest is $1500.

<h3>What are the linear equations that can be derived from the question?</h3>

a + b = $2500 equation 1

0.088a + 0.114b = $246 equation 2

Where:

a = amount borrowed from the lender that charges 4.4% interest

b =  amount borrowed from the lender that charges 5.7% interest

<h3>How much was borrowed from the lender that charges 5.7% interest?</h3>

Multiply equation 1 by 0.114

0.114a + 0.114b = 285 equation 3

Subtract equation 2 from equation 3

39 = 0.026b

b = $1500

<h3>How much was borrowed from the lender that charges 4.4% interest?</h3>

Substitute for b in equation 1

a + $1500 = $2500

a = $2500 - $1500

a = $1000
