Answer:
1/2x+7
Step-by-step explanation:
8160 dived by 85 equals 96, 2880 divided by 30 equals 96, therefore she can make 96 necklaces
Answer: x = -2
<u>Step-by-step explanation:</u>
vertical line means it will be x = ___
Set the x-values equal to each other and solve for x.
3 - 2x = x + 9
<u> +2x</u> <u>+2x </u>
3 = 3x + 9
<u>-9 </u> <u> -9 </u>
-6 =3x

-2 = x
Hi there!

The two trapezoids are similar, so we can determine a common scale factor:
OL/UR = NM/TS
9/3 = 6/2
3 = 3
Trapezoid ONML is 3x larger than UTSR, so:
RS = 4, LM = y
3RS = LM
3 · 4 = y = 12.
Find x using the same method:
3UT = ON
3(2x+1) = 4x + 9
6x + 3 = 4x + 9
2x = 6
x = 3.
Your answer would definitely be the 3rd answer choice.
