Which value of x from the set {5, 6, 7, 8} makes this equation true? 3x = 24
Tju [1.3M]

Answer:

Value x = 8 make the equation true .

Step-by-step explanation:

Given  : 3x = 24.

To find : Which value of x from the set {5, 6, 7, 8} makes this equation true?

Solution : We have given 3x = 24.

The equations are true when the Left hand side and right hand side of the equation are equal.

Then,

For x = 8 .

3 ( 8) = 24

24 = 24 .

Hence,

Left hand side = Right hand side.

Therefore, Value x = 8 make the equation true .

Three fifths of the children in a school are boys. 7/8 of the girls in the school are right-handed. What fraction of the childre
Kaylis [27]

Answer:

To find the answer we only need to know,

Total no.of girls and Total no.of right handed girls.

So,

Total no.of right handed girls = 7/8

Total no.of girls                        = 8/8 (as given in question)

Total no.of left handed girls is,

(Fraction of total no.of girls) - (Fraction of total no.of left handed girls)

= 8/8 - 7/8

= 1/8

∴ 1/8 of the girls in the school are left handed.

WILL GIVE BRAINLIEST FOR CORRECT ANSWER !
lesya692 [45]

Answer:

neither

Step-by-step explanation:

The second and 3rd one can be modeled by by y = 100/x but the first one and the fourth one do not follow that, so the answer is neither. The first and fourth are y = 80/x

Put the values in and you will see the equations for yourself.

One

y = 80/2

y = 40

The 80 came from looking at this as an indirect variation. y = k/x

y = 40

x = 2

y = k/x

40 = k/2  Multiply both sides by 2

40 * 2 = k

k = 80

Two

y = k/x

20 = k/5

k = 20 * 5

k = 100
