Simplify brackets
351 = y * 8 + 7
Regroup terms
351 = 8y + 7
Subtract 7 from both sides
351 - 7 = 8y
Simplify 351 - 7 to 344
344 = 8y
Divide both sides by 8
344/8 = y
Simplify 344/8 to 43
43 = y
Switch sides
<u>y = 43</u>
Answer:
she is wrong because 1800/9 is 200.
Answer:
If sam had x accounts, then ruby had 9x then:
X + 9X = 120
10X = 120
X = 120/10
X = 12
If ruby had 9x then she had:
9(12) = 108
And Sam:
12
108 - 12 = 96
Ruby had 96 more accounts than Sam

Answer:
he sum of the angles in all these triangles will be n x 180 degrees. The sum of the angles around the interior point is clearly 360 degrees, so the sum of the polygon’s angles will be (180n)-360 = (n-2) x 180 degrees.Here we have (n-2) x 180 = 2160, so n-2 = 12. So the polygon has 14 sides. 606 views
