e-lub [12.9K]
Since the area of a rectangle is base times height.
Combining the two areas, we get
A(total) = A1 + A2 = (20*5) + (12*3) = 136 square yard

The answer is A.

18. Find the value of x that makes the equation true.
IgorC [24]

Step-by-step explanation:

✧ \large{ \tt{ \:  \frac{1}{2} x + 2 =  \frac{3}{2} x - 6}}

We need to get rid of the fractions. Notice that there are 4 terms in the equation. Multiply both sides of the equation by 2 to get rid of the fractions. Multiply by 2 because 2 is the denominator.

⤑ \large{ \tt{2( \frac{1}{2} x + 2) = 2( \frac{3}{2} x - 6)}}

⤑ \large{ \tt{x + 4 = 3x - 12}}

Subtract 4 from both sides in order to isolate the variable on the left.

⤑ \large{ \tt{x + 4 - 4 = 3x - 12 - 4}}

⤑\large{  \tt{x = 3x - 16}}

Move 3x to left hand side and change it's sign

⤑\large {\tt{x - 3x  =  - 16}}

Subtract 3x from 1x

⤑ \large{ \tt{ - 2x =  - 16}}

Divide both sides of the equation by -2

⤑ \large{ \tt{ \frac{ - 2x}{ - 2}  =  \frac{ - 16}{ - 2}}}

⤑ \large{ \tt{x = 8}}

\boxed{ \boxed{ \underline{ \tt{Our \: Final \: Answer :  \boxed{ \underline{ \tt{x = 8}}}}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ

While doing back to school shopping on tax-free weekend, Mrs. Michaels bought 2 packs of mechanical pencils and 3 binders for a
IRISSAK [1]

Answer:

$3.00  

Step-by-step explanation:

Let p = the cost of a pack of pencils

and b = the cost of a binder

Then we have two simultaneous equations.

(1)  2p + 3b  = 21.00

(2) 5p + 2b = 25.00

1. Multiply each equation by numbers to give one of the variables the same coefficient.

Multiply (1) by 2 and (2) by 3.This gives

(3)  4p + 6b = 42.00

(4) 15p + 6b = 75.00

2. Subtract (3) from (4)

This gives

(5) 11p = 33.00

3. Solve equation (5) for p

Divide each side by 11

p = 3.00

Each pack of pencils costs $3.00.
