What is 3m-8=5m+8 simplified

Answers

Answer 1

Answer:

since you have variables on both sides, you have to subtract the smallest varable from both sides that HAVE the variable. so 3m-8=5m+8

3m-8=5m+8

-3m -3m

-8=2m+8

isolate the variable by subtracting 8 from both sides

-16=2m

isolate the variable again by dividing both sides by 2

so -8=m

now you have to put -8 into the equation

(checking)

3(-8)-8=5(-8)+8

-24-8=-40+8

-32=-32

Answer 2

Answer: 3m-8= 5m+8need to have variables on one side and numbers on the othermove the smaller numbers to avoid negative numberssubtract 3m from both sides-8= 2m+8subtract 8 from both sides-16 = 2m-8 = m

A cheetah’s speed was timed over a 100- yard distance. The cheetah was clocked running 70 miles per hour. Which equation shows the relationship between the distance, y, and time, x, the cheetah runs?A y=100x C y=100x+70
B y=70x+100 D y=70x

Answers

Speed is the rate of change of distance over time.

The equation that shows the relationship is $y = 70x$

The given parameters are:

Distance = 100 yards

Speed = 70 miles per hour

Speed is calculated as:

$Speed = Distance / Time$

So, we have:

$70 = y/x$

Multiply both sides by x

$y = 70x$

Hence, the equation that shows the relationship is $y = 70x$

Answer with Step-by-step explanation:

The cheetah was clocked running 70 miles per hour.

i.e. in 1 hour cheetah covered 70 miles

in 2 hours cheetah covered 140 miles

in 3 hours cheetah covered 210 miles

in general, in n hour cheetah covered 70n miles

If y denote the distance covered

and x denotes the time cheetah runs

Then, y=70x

Hence, the equation which shows the relationship between the distance, y, and time, x, the cheetah runs is:

D y=70x
