A car is traveling at a rate of 80 kilometers per hour. What is the car's rate in miles per hour? How many miles will the car travel in 3 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.

The car's rate is 50 miles per hour, and it will travel 150 miles in 3 hours

Step-by-step explanation:

There are about 1.6 kilometres in a mile, meaning that in 80 miles there are about 50 miles. This means that the car's rate in miles per hour is about 50. This means that in 3 hours, it will travel about 50*3=150 miles. Hope this helps!

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
