Solve for x:
25 x - 6 = 5 x + 24

Subtract 5 x from both sides:
(25 x - 5 x) - 6 = (5 x - 5 x) + 24

25 x - 5 x = 20 x:
20 x - 6 = (5 x - 5 x) + 24

5 x - 5 x = 0:
20 x - 6 = 24

Add 6 to both sides:
20 x + (6 - 6) = 6 + 24

6 - 6 = 0:
20 x = 24 + 6

24 + 6 = 30:
20 x = 30

Divide both sides of 20 x = 30 by 20:
(20 x)/20 = 30/20

20/20 = 1:
x = 30/20

The gcd of 30 and 20 is 10, so 30/20 = (10×3)/(10×2) = 10/10×3/2 = 3/2:

Answer: x = 3/2

25x - 6 = 24 + 5x
First we collect terms
20x = 30
Now we divide by 20
x = 30/20
x = 1.5

A student council sold 856 copies of a school yearbook, four fifths of the students at the school bought a copy , how many stude

kumpel [21]

Answer:

I am guessing about 150 - 200 students did not buy a yearbook.

Step-by-step explanation:

First let's assume that there are 1,000 or so students in the school. 856 would be a little over 4/5 of 1,000 just as 8 would be 4/5 of 10.

A cyclist travels 4 miles in 15 minutes and then a further 6 miles in 25 minutes without stopping.

Tcecarenko [31]

Total distance traveled = 4 + 6 = 10 miles

Total time = 15 + 25 = 40 minutes

Speed = 10 miles ÷ 40 minutes = 0.25 mph

Suppose the height of the pyramid is 20 yards. What is the pyramid's volume?

DedPeter [7]

Answer : The correct option is, (B) 1500 cubic yards.

Step-by-step explanation :

Formula used to calculate the volume of square pyramid is:

$V=\frac{a^2\times h}{3}$

where,

V = volume of pyramid

a = base edge of pyramid

h = height of pyramid

Given:

Base edge of pyramid = 15 yards

Height of pyramid = 20 yards

Now putting all the given values in the above formula, we get:

$V=\frac{a^2\times h}{3}$

$V=\frac{(15\text{ yrads})^2\times (20\text{ yards})}{3}$

$V=1500\text{ yards}^3$

Therefore, the volume of pyramid is 1500 cubic yards.

What is the solution to this equation?<br> x-8=15<br><br> A)x=13<br> B)x=17<br> C)x=7<br> D) x=23

Blababa [14]

Hi there! :)

<u><em>Answer:</em></u>

<u><em>x=23</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

Step-by-step explanation:

This lesson it's about addition property of equality.

First, you add by 8 from both sides of an equation.

$x-8+8=15+8$

And then, you add by the numbers. Simplify and solve.

$15+8=23$

Final answer: → $x=23$

Hope this helps!

Thanks!

Have a great day!
