Answer:

Melody added 12 to both sides when she should've subtracted 12 from both sides.

X = 19

Step-by-step explanation:

When solving equations, you have to do the opposite operation given on both sides of the equation. In this case, the operation that's happening is addition, so we have to <u>subtract</u> 12 from both sides.

Step 1: Subtract 12 from both sides.

$x+12-12=31-12$
$x = 19$

Mickey and Donald earn $53 weekend after taxes Mickeys share is seven dollars greater than Donald's how much does Donald earn ea

igor_vitrenko [27]

Donald earns $23 each weekend and Mickey earns $30.

Step-by-step explanation:

Given,

Money earned by Mickey and Donald = $53

Let,

Share of Mickey = x

Share of Donald = y

According to given statement;

x+y=53 Eqn 1

x = y+7 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$(y+7)+y=53\\y+7+y=53\\2y=53-7\\2y=46$

Dividing both sides by 2

$\frac{2y}{2}=\frac{46}{2}\\y=23$

Putting y=23 in Eqn 2

$x=23+7\\x=30$

Donald earns $23 each weekend and Mickey earns $30.

Mark said he can decompose the fraction 5/6 into three numerator.Is this possible? Explain.

OlgaM077 [116]

Ni because if you divide or mulriply the denominator you have to multiply or divide the numerator by the same amount. It is not possible dince you can divide the denominator by 2 to get 3 but you cant divude 5 by 2 and get an evn number

$\bf \cfrac{8m^7}{n}\implies 8m^7n^{-1}\implies 2^3m^{3+3+1}n^{-1}\implies 2^3m^3m^3m^1n^{-1}
\\\\\\
2^3(m^2)^3mn^{-1}\implies (2m^2)^3mn^{-1}$
