Hey there!

-7u - 7 = 7

ADD 7 to BOTH SIDES

-7u - 7 + 7 = 7 + 7

CANCEL out: -7 + 7 because it give you 0

KEEPs 7 + 7 because it help solve for the u-value

NEW EQUATION: -7u = 7 + 7

SIMPLIFY IT!

-7u = 14

DIVIDE -7 to BOTH SIDES

-7u/-7 = 14/-7

CANCEL out: -7/-7 because it give you 0

KEEP: 14/-7 because it give you the

u-value

NEW EQUATION: u = 14/-7

SIMPLIFY IT!

u = -2


SOLVING FOR : 9u - 2

9u - 2

= 9(-2) - 2

= -18 - 2

= -20


Therefore, your answer is: -20

Good luck on your assignment & enjoy your day!

Degger [83]

Answer:

a = 16 and b = 13

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, so

CD = AB , that is

3a - 10 = 2a + 6 ( subtract 2a from both sides )

a - 10 = 6 ( add 10 to both sides )

a = 16

The diagonals of a parallelogram bisect each other, so

AO = CO , that is

2b = 26 ( divide both sides by 2 )

b = 13

Leah claims that these figures are not similar. When she compared the heights, she wrote 27. Then she compared the bases and got
Flauer [41]

Answer:

<h2>Leah is actually wrong, because those rectangles are similar.</h2>

Step-by-step explanation:

Remember that similarity is about having proportional sides and congruent angles. When we have congruent sides, then those rectangles are congruent not similar.

In this case, to find the similarity, Leah should compare bases and heights thorugh division, because the ratio between heights and the ratio between bases must be equal. So, let's divide.

\frac{21}{6}=3.5

\frac{7}{2}=3.5

As you can observe, both ratios are equal.

Therefore, those rectangles are congruent.

disa [49]

Answer:

the  revenue recognized is $1,275

Step-by-step explanation:

The computation of the revenue recognized is shown below:

= Number of boxes of strawberries sold to customers × price per box

= 85 boxes × $15

= $1,275

Hence, the  revenue recognized is $1,275

We simply applied the above formula and the same should be considered

Also

= 130 - 85

= 45 boxes would not be recognized as sale is not made
