2. Lamar purchases comic books at garage
Otrada [13]

<u>Answer:</u>

Lamar will charge\$7 to the comic dealer for a comic book.

<u>Solution:</u>

It is given that lamar purchases a comic book for \$4. He then marks up the price of a comic book by 75\% which means he increases the price of the book by 75\% and then sells it to the comic dealer.

We have to find out how much will he charge the comic book dealer.

New price of the book after lamar marks up the price is given by

New price =  \$4 + \frac{75}{100} \times \$4

=\$4 + \$3= \$7

Thus, lamar will charge \$7 to the comic dealer for a comic book.

What is three more than the product of a number and 7 equals 8 . use the variable x for the unknown number?
Anastaziya [24]
(7x) + 3 = 8
subtract both sides by 3.

7x = 5
divide both sides by 7 to isolate the variable, x.

x = 5/7

Triangle X Y Z is shown. The length of side X Y is (9 n + 12) feet and the length of side X Z is (15 n minus 6) feet. Angles X Y
posledela

*the figure is shown in the attachment

Answer/Step-by-step explanation:

Since <XYZ and <YZX are said to be congruent, therefore, the side opposite to each of the angle are also equal. Therefore, ∆XYZ is an isosceles ∆.

Find the value of n by creating an equation to solve for n:

XY = (9n + 12) ft

XZ = (15n - 6) ft

XY = XZ (2 equal lengths of isosceles ∆)

9n + 12 = 15n - 6 (substitution)

Combine like terms

9n - 15n = - 12 - 6

-6n = -18

Divide both sides by -6

-6n/-6 = -18/-6

n = 3

Find the length of leg XY by substituting n = 3 into XY = (9n + 12) ft.

XY = (9(3) + 12) ft

XY = (27 + 12) ft

XY = 39 ft

Find the length of leg XZ by substituting n = 3 into XZ = (15n - 6) ft.

XZ = (15(3) - 6) ft

XZ = (45 - 6) ft

XZ = 39 ft
