2d(3*6)=48y when y=1/4

vaieri [72.5K]

Answer: d = 1/3

Step-by-step explanation: 48y = 48/4 = 12. So, 2d(18) is equal to 12. 12/18 is 2/3 so 2d has to equal 2/3. That means d = 1/3.

Can someone help me really please

Answer:

Step-by-step explanation:

Let x represent the missing number

$8\frac{11}{15} = 7\frac{x}{15}$

Convert both fractions to improper fractions

$\frac{131}{15} = \frac{105 + x}{15}$

Cross multiply

$15(105 + x) = 15(131)$

$1,575 + 15x = 1,965$

Subtract both sides by 1,575

$15x = 1,965 - 1,575$

$15x = 390$

Divide both sides by 15

$x = \frac{390}{15}$

x = 26
