2 and 1/2 years = 30 months

$20 \times 30 = 600$
$100\% - 75\% = 25\%$
$600 \times 25\% = 150$
The answer is A. $150

Hope this helps.

Elizabeth has a lot of jewelry. She has four times as many earrings as watches but half the number of necklaces as earrings. Eli

evablogger [386]

Given:
Total number of pieces: 117
watch = x
earrings = four times as many earring as watches = 4x
necklaces = half the number of necklaces as earrings = 1/2 * 4x = 2x
bracelets = necklaces = 2x

x + 4x + 2x + 2x = 117
9x = 117
x = 117/9
x = 13

watches: x = 13
earrings: 4x = 4(13) = 52
necklaces: 2x = 2(13) = 26
bracelets: 2x = 2(13) = 26

13 + 52 + 26 + 26 = 117

There are 13 watches, 52 earrings, 26 necklaces, and 26 bracelets.

Can someone pls help?

Sergio [31]

<h3>Answer: x = 4</h3>

==================================================

Explanation:

Use the remote interior angle theorem. This says a pair of interior angles always add to the measure of the exterior angle that is not adjacent to any of the interior angles, so basically what your diagram is showing.

(interior angle C) + (interior angle D) = exterior angle

(46) + (-1+8x) = 18x+5

8x+45 = 18x+5

8x-18x = 5-45

-10x = -40

x = -40/(-10)

x = 4

Victor is ordering pizzas for a party. He would like to have 1/4 of a pizza for each guest. He can only order whole pizzas, not

sertanlavr [38]

7 pizzas, because you would divide 27 by 4 and get 6.75 and then round it up to 7.

Hope this helped :)

Use the same coordinate plane to draw the graphs of the functions. Y=kx-2 if k=1, 0.4,-1

mario62 [17]

Graphs can be used to represent functions.

See attachment for the graphs of: <em>y =x - 2, y = 0.4x - 2, y =-x - 2</em>

The function is given as: $\mathbf{y = kx - 2}$

When k = 1,

We have:

$\mathbf{y = 1\times x - 2}$ ----- substitution property of equations

$\mathbf{y = x - 2}$

So, the equation is: $\mathbf{y = x - 2}$ when k = 1

When k = 0.4,

We have:

$\mathbf{y = 0.4\times x - 2}$ ----- substitution property of equations

$\mathbf{y = 0.4x - 2}$

So, the equation is: $\mathbf{y = 0.4x - 2}$ when k = 0.4

When k = -1,

We have:

$\mathbf{y = -1\times x - 2}$ ----- substitution property of equations

$\mathbf{y = -x - 2}$

So, the equation is: $\mathbf{y = -x - 2}$ when k = -1

See attachment for the graphs of: $\mathbf{y = x - 2}$ , $\mathbf{y = 0.4x - 2}$ and $\mathbf{y = -x - 2}$
