Simplify the equation 815 = 3x

Answers

Answer 1

Answer:

Answer:

271.6 or 272

Step-by-step explanation:

815 is being times by 3

so we do the opposite

815/3 on both sides

3x/3=0

drop the x

then do 815/3

= x= 271.6 or 272

Answer 2

Answer:

Final answer:

To simplify the equation 815 = 3x, divide both sides of the equation by 3 to isolate the variable x. The solution to the equation is x = 271.

Explanation:

To simplify the equation 815 = 3x, we need to isolate the variable x on one side of the equation.

To do this, we divide both sides of the equation by 3 to cancel out the coefficient of x.

This gives us x = 815/3. Performing the division, we get x = 271.

Therefore, the solution to the equation is x = 271.

If m\angle CED=101 then what is m\angle CEH∠CEH

Answers

Answer:

m∠CEH = 79°

Step-by-step explanation:

From the picture attached,

∠CED and ∠CEH are the pair of linear angles.

Since, pair of linear angles are supplementary angles.

m∠CED + m∠CEH = 180°

101° + m∠CEH = 180°

m∠CEH = 180° - 101°

= 79°

Therefore, measure of angle CEH is 79°.

What values of x will make x^2 = 16 true ?

Answers

Answer:

x = 4, x = -4

Step-by-step explanation:

In order to solve this equation, we need to square-root bothsides.

$\sf{x^2=16}$

$√(x^2)=√(16)$

Simplify:

$x=4,x=-4$

Answer:

x = -4 or 4

Step-by-step explanation:

⇒ $x^2=16$

⇒ $x = √(16)$

∴ $x =$ ± 4

Therefore, x can be either 4 or -4 such that $x^2=16$ .

if julie ran 3.6 miles from home to the gym and then walked 0.7 miles to the store she then ran from the store home if her total distance covered after she returned from the store was 7.2 miles how far is it from the store to her home? write and simplify and expression that would represent the distance she covered.

Answers

So,

Home ---- gym = 3.6 mi.
gym ---- store = .7 mi.
store ----- home = x

3.6 + .7 + x = 7.2 mi.

Collect Like Terms

4.3 + x = 7.2

Subtract 4.3 from both sides
x = 2.9

The distance from the store to her home is 2.9 miles.

There are 80
students in a speech contest. Yesterday,

1

4
of them gave their speeches. Today,

2

5
of the remaining students gave their speeches. How many students still haven't given their speeches?

Answers

yesterday, 1/4 of 80 =20 gave their speeches, so there are 80-20=60 students left.
Today, 2/5 of 60=24 students gave their speeches, so there are 60-24=36 students who still haven't give their speeches
another way to think of it is 80*(1- 1/4)*(1- 2/5)=80*(3/4)*(3/5)=36

Final answer:

To find the number of students who haven't given their speeches, subtract the number of students who have given their speeches from the total number of students. Yesterday, 14 students gave their speeches and today, 25 more students gave their speeches. So, there are 41 students who still haven't given their speeches.

Explanation:

To find the number of students who haven't given their speeches, we need to subtract the number of students who have given their speeches from the total number of students.

Yesterday, 14 students gave their speeches, so there are 80 - 14 = 66 students remaining.

Today, 25 students gave their speeches, so there are 66 - 25 = 41 students who still haven't given their speeches.
