both angles would equal the same so you have:

6x-57 = 2x+15

add 57 to each side:

6x = 2x+72

subtract 2x from each side:

4x = 72

divide:

x = 72/4 = 18

now replace x with 18:

6(18) - 57 = 51

2(18) +15 = 51

51 +51 = 102

Angle QNR = 102 degrees

Addies has 7 grades on her report card. The overall average is 77%. One grade was incorrectly recorded as 18% instead of the act

inessss [21]

77(7) = 539, the total points of all her tests

539 - 18 + 81 = correct total points = 602

602/7 = 86 which is the new average

Round 10.09 To The Nearest Whole Number

ziro4ka [17]

Answer=10

When rounding to the nearest whole number, we need to look to the number in the tenths place

10.09

If the number is 5 or greater, we round up. If the number is 4 or less, we round down.

The number is 0, so we would round down.

10.09 becomes 10

Simplify 3 - b (7b + 2) + 3b - (11 - b)

nirvana33 [79]

Answer: -7b² + 2b - 8

Step-by-step explanation:

Given expression

3 - b (7b + 2) + 3b - (11 - b)

Expand parentheses and apply the distributive property if necessary

=3 - b · 7b - b · 2 + 3b - 11 + b

=3 - 7b² - 2b + 3b - 11 + b

Combine like terms

=-7b² + (3b - 2b + b) + (3 - 11)

= $\boxed{-7b^2+2b-8}$

Hope this helps!! :)
