Isolate the a. Note the equal sign. What you do to one side, you do to the other.

Add 5 to both sides

-5 (+5) + 1/5a = 4 (+5)

1/5a = 9

Isolate the a. Multiply 5 to both sides

(5)(1/5)a = 9(5)

a = 9 x 5

a = 45

45 is your answer for a.

hope this helps

Four squares are joined together to form one large square if the perimeter of one of the original squares of 8X units what is th

allsm [11]

Answer:

16 x units

Step-by-step explanation:

Perimeter of a original square= 8 x units

Perimeter of a square= 4× side

Side of a square = $\frac{perimeter}{4}$

Side of a square = $\frac{8x}{4}$

Side of a square= 2 x units

since four square are joined together to form a single square

So each side of a bigger square= 4 x units

Perimeter of a new bigger square= 4 × 4 x units

Perimeter of a new bigger square= 16 x units

Hence, the correct answer is 16 x units

algol13

Answer:

$x$

Step-by-step explanation:

$\frac{7-2x}{-4} +2$

Subtract 2 from both sides

$\frac{7-2x}{-4}$

mutliply both sides by -4, flip the inequality

Add 2x on both sideds

$7>6x+8$

Subtract 8 from both sides

$-1>6x$

Divide both sides by 6

$x$

Mark walks 1/2 miles in 3/4 of an hour what is the unit rate per hours

lana [24]

Answer:

$unit \: rate = \frac{distance}{time} \\$

substitute:

$unit \: rate = \frac{( \frac{1}{2} )}{ ( \frac{3}{4}) } \\ \\ = \frac{1}{2} \div \frac{3}{4} \\ \\ = \frac{1}{2} \times \frac{4}{3} \\ \\ = \frac{4}{6} \\ \\ = { \underline{ \: \: \frac{2}{3} \: \: miles \: per \: hour \: \: }}$
