Consecutive means right after each other
difference of 1
numbers are
x,x+1,x+2
their sum is 117
x+x+1+x+2=117
add
3x+3=117
subtract 3 form both sides
3x=114
divide both sides by 114
x=38
largest number is x+2
38=x
x+2=38+2=40

largest number is 40

Divide 117 by three to get the middle name number, then you subtract one and add one to 1 of the three 39's to get your numbers as 38, 39, 40. And the largest number. Is 40. Hope this helped.

Reena has 12 more dimes than she does quarters. If Reena has a total of 28 coins, how many quarters, qq, and how many dimes, dd,
erastovalidia [21]
Q = d - 12
q = 28 - d

d - 12 = 28 - d
d + d = 28 + 12
2d = 40
d = 40/2
d = 20 <== 20 dimes

q = d - 12
q = 20 - 12
q = 8 <== 8 quarters

Answer:

\huge\boxed{\sf 126\° \ OR \ 145 \°}

Step-by-step explanation:

m∠4 + m∠7 = 180    (Adjacent Angles of a parallelogram)

<u>Given that</u> m∠4 = x + 45, m∠7 = x² + 45

x + 45 + x² + 45 = 180

x² + x + 90 = 180

x² + x = 180 - 90

x² + x = 90

x² + x - 90 = 0

Using mid-term break formula

x² + 10x - 9x - 90 = 0

x(x+10) - 9(x+10) = 0

(x - 9)(x + 10) = 0

<u>Either, </u>

x-9 = 0       <u>OR</u>      x+10 = 0

x = 9          <u>OR</u>        x = -10

\rule[225]{225}{2}

Now,

m < 7 = x² + 45

<u>For x = 9</u>

m < 7 = (9)² + 45

m < 7 = 81 + 45

<h3>m < 7 = 126°</h3>

<u>For x = -10</u>

m < 7 = (-10)² + 45

m < 7 = 100 + 45

<h3>m < 7 = 145°</h3>

\rule[225]{225}{2}

Hope this helped!
