Answer:

A 20.8 cm

Step-by-step explanation:

The perimeter of a rectangle is

P = 2(l+w)

We know the length is 8cm and the width is 24mm

The need to be the same units to add them together

Change 24 mm * 1cm/10 mm = 2.4 cm

Substitute 8 cm for l and 2.4 cm for w

P = 2(8+2.4)

P = 2 (10.4)

P = 20.8 cm

Marina CMI [18]

Answer:

ABC = 35

Step-by-step explanation:

x and 3x-70 are corresponding angle and corresponding angle are equal when the lines  are parallel

x-3x = 3x-70-3x

-2x= -70

Divide by -2

-2x/-2 = -70/-2

x = 3x-70 = 35

A bracelet that normally sells for $30.00 is on sale for $25.50. What is the percent discount?
vekshin1

Answer:

15% off

Step-by-step explanation:

We know we paid $25.50 of the original $30. We can divide these two numbers \frac{25.5}{30}=0.85. This is means we paid 85% of the original price. The discount percentage is the remaining percentage from 85 to 100 which is 15. The pants were 15% off.
