16 + 32y

(-2-4y)(-8)
Use distributive property:
(-2*-8)+(-4y-8)
(remember that when 2 negative numbers are multiplied together it becomes positive.

16+32y

Hope this helps :)

What is 66 2/3 as a fraction
beks73 [17]
66 x 3 = 198
198 + 2 = 200
200 / 3

As an improper fraction, anyway. 66 2/3 is already *technically* a fraction.

Katherine has $140 in the bank and is saving $6 per week. Abbie has $462 in the bank, but is spending at a rate of $10 per week.
AveGali [126]
Let x be the number of weeks for this financial situation. The amount that Katherine will have at the end of x weeks is 140 + 6x. On the other hand, with the spending that she is doing, Abbie will have 462 - 10x after x weeks. Equating the two,
                                     140 + 6x = 462 - 10x
Thus, the answer is letter B.

Triangle VDG- triangle VNQ <br> What is the value of x? <br> Enter your answer in the box.
AleksAgata [21]

Question:

The image of the question is attached below.

Answer:

x = 40

Solution:

Given ΔVDG \sim ΔVNG.

DG = 207, NQ = 138, GQ = 60, QV = x

In two triangles are similar, then the measures of the corresponding sides are in proportional to each other.

$\Rightarrow\frac{DG}{NQ}=\frac{GQ}{QV}

$ \Rightarrow\frac{207}{138}=\frac{60}{x}

Do cross multiplication, we get

$ \Rightarrow{207\times x}=138\times60

$ \Rightarrow{207\times x}=8280

$ \Rightarrow{207x}=8280

Divide by 207 on both sides of the equation, we get

$ \Rightarrow\frac{{207x}}{207} =\frac{8280}{207}

$ \Rightarrow x =\frac{8280}{207}

⇒ x = 40

⇒ QV = 40

Hence the value of x is 40.
