Answer:

126

Step-by-step explanation:

21 + 4 = 25 (blue plus white marbles)

150/25 = 6 (all the marbles divided by how many we know are white and blue)

21 x 6 = 126

Whatis the value of y?

Romashka [77]

Answer is A, y = 65

The top angle is 50 because 180 - 130 = 50
Since the top angle is 50, the two bottom angles have to add up to 130. Since the bottom angles are the same, you can do 130 / 2 to find the angles which equals 65.

To divide fractions, you multiply by the reciprocal of the second fraction.

kicyunya [14]

This is true.

Example:

= 8/9 ÷ 7/3
to divide fractions, multiply by the reciprocal/inverse of 7/3

= 8/9 * 3/7

= (8*3)/(9*7)
multiply numerators; multiply denominators

= 24/63
simplify

= 8/21

ANSWER: This is (A) true

Hope this helps! :)

What is 2/9 = 4/x+8 i dont get this fraction solving

Dmitriy789 [7]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$\frac{2}{9} = \frac{4}{x + 8} \\$

$\frac{4}{x + 8} = \frac{2}{9} \\$

Inverse both sides

$\frac{x + 8}{4} = \frac{9}{2} \\$

Multiply sides by 4

$4 \times \frac{x + 8}{4} = 4 \times \frac{9}{2} \\$

$x + 8 = 2 \times 9$

$x + 8 = 18$

Subtract sides 8

$x + 8 - 8 = 18 - 8$

$x = 10$

Done...
