Mathematics

Answer:

x = 21/4

Step-by-step explanation:

re-arrange the equation

-4+5x-7-3x = 10-2x (move 3x to the other side)

-4+5x-7-3x+2x = 10 (move 2x to the other side)

5x-7-3x+2x = 10+4 (move 4 to the other side)

5x-3x+2x = 10+4+7 (move 7 to the other side)

4x = 21 (add up both sides)

x = 21/4 (divide both sides by 4

Ket [755]
Hi there,

No, it isn't

5x - 3 = 12
5x = 12 + 3
5x =15

Hence, X = 3

3 is the solution

the ratio of students at a school is 3 boys for every 4 girls. If there are 52 girls how many boys are in the school
vova2212 [387]
There are 39 boys. 
First you divide 4 into 52 because there are 3 boys for 4 girls. 
Then you take the quotient, 13, and multiply by 3.

Step by step explanation please. i want to try to understand it.
zhenek [66]

Answer:

V_{composite\: figure} =678.24\: in^3

Step-by-step explanation:

  • For a single cylinder:

  • radius (r) = 3 in (Given)

  • height (h) = 8 in (Given)

  • It is given that: all the three cylinders are identical, means their radii and heights are equal.

  • Thus, the volume of composite figure will be equal to three times the volume of single cylinder.

  • \implies V_{composite\: figure} =3(\pi r^2 h)

  • \implies V_{composite\: figure} =3(3.14\times  (3)^2 \times 8)

  • \implies V_{composite\: figure} =3(226.08)

  • \implies V_{composite\: figure} =678.24\: in^3
