RSB [31]

Answer:

Jarrett has 75 comics

Step-by-step explanation:

T = Number of comic books Toby has.

M = Number of comic books Mitch has.

J = Number of comic books Jarrett has.

Toby has 75% as many comic books as Mitch.

T = 3/4 * M

This is because 75% = 75/100 = 3/4

Jarrett has 25% more comic books than Mitch.

J = 5/4 * M

This is because 125% = 125/100 = 5/4

If Toby has 45 comic books, how many comic books does Jarrett have.

1) Substitute T = 45 and Solve for M

T = 3/4 * M

45 = 3/4 * M

45 ÷ 3/4 = M

45 * 4/3 = M

180/3 = M

M = 60

2) Substitute M = 60 and Solve for J

J = 5/4 * M

J = 5/4 * 60

J = 300/4

J = 75

Jarrett has 75 comics

Question

Zinaida [17]

Answer:

$\frac{x}{5}-6=15$

(addition property of equality)

$\frac{x}{5}=21$

(multiplication property of equality)

$x=105$

Step-by-step explanation:

Given:

$\frac{x}{5}-6=15\\\frac{x}{5}=21\\x=105$

To find: appropriate properties to justify each step

Solution:

According to division property of equality, if both sides of an equation are divided by the same nonzero number, the sides remain equal.

According to multiplication property of equality, if both sides of an equation are multiplied by the same nonzero number, the sides remain equal.

According to addition property of equality, if same number is added to both sides of an equation, the sides remain equal.

According to subtraction property of equality, if same number is from both both sides of an equation, the sides remain equal.

$\frac{x}{5}-6=15$

Add 6 to both sides ( addition property of equality )

$\frac{x}{5}-6+6=15+6\\\\\frac{x}{5}=21$

Multiply both sides by 5 (multiplication property of equality)

$\frac{x}{5}=21\\\frac{x}{5}(5)=21(5)\\ x=105$
