Can someone pls explain to me how to do this (^｡^)

Answer:

Area: $\frac{8}{15}$ feet²

Perimeter: $\frac{44}{15} =2 \frac{14}{15}$ feet

Step-by-step explanation:

The formula of finding the area of a rectangle or square is width multiplied by length.

The formula of find the perimeter of a rectangle or square is width+width+length+length

Area: $\frac{4}{5} *\frac{2}{3} = \frac{8}{15}$ feet²

Perimeter:

$\frac{4}{5} +\frac{4}{5} +\frac{2}{3} +\frac{2}{3} =$

$\\\\\frac{12}{15} +\frac{12}{15} +\frac{10}{15} +\frac{10}{15} =\\\\\frac{24}{15} +\frac{20}{15} =\\$

$\frac{44}{15} =2 \frac{14}{15}$

Two cars are traveling on two different routes, one 43 miles longer than the other. The car traveling on the longer route travel

Anestetic [448]

Answer:

x1 = 275 miles (shorter)

x2 = 318 miles (longer)

Step-by-step explanation:

Let

x1 = be the shorter route

v1 = speed of the car in the shorter route

t1 = time it took to cover shorter route

x2 = the longer route

v2 = speed of the car in the longer route

t2 = time it took to cover longer route

x1 + 43 = x2 (1)

v2 = v1 -2 (2)

v2 = x2/t2 = x2/6

v1 = x1/t1 = x1/5

This means that

v2 = v1 -2 =>

x2/6 = x1/5 -2

The system of equations results

a. x1 -x2 = -43

b. x1/5 - x2/6 = 2

Solving this system of equations, we find that

x1 = 275 miles

x2 = 318 miles

3(x+10)=2(2x+16) help please & thank you

andrew-mc [135]

In this question, you have to isolate x.

First, use the distributive property.

$3x+30=4x+32$

Now that you have distributed, subtract the constants.
