Answer:
(1) 9n = 56
<u>n = 6</u>
(2) 10 + 4y = 38
<u>y = 7</u>
(3) 3x + 8x = 55
<u>x = 5</u>
(4) 6m + 20 = 8
<u>m= -2</u>
(5) 17 - 3a = 23
<u>a = -2</u>
(6) 10x + 4 = 6x + 16
<u>x = 3</u>
(7) 4(x - 2) + x = 17
<u>x = 5</u>
(8) 2(x + 3) + 3x = x + 22
<u>x = 4</u>
(9) <u>D. 10</u>
(10) -2(3x - 2.4) = 3(3x - 2.4)
im not sure about this equation

K = 5 because according to cross multipication, which is what you need to do to get an answer for these kinds of questions, you have to times 6 by 15 then divide that answer by 18 and you have your answer: 5 (6 x 15 = 90 90 / 18 = 5)
Her box is 12 inches tall.
-Because if you multiply 13 × 5, you get 65 (this is the base) then you work backwards and divide 780 by 65 (780 ÷ 65). Therefore your answer is 12 inches
Answer:
-8b + 9 - 5k
Step-by-step explanation:
I am assuming the blue highlighted portion is your answer, and is not a part of the initial question
(-4b + 15 - 7k) - (6 + 4b - 2k)
Combine like terms
-4b - + 4b
Negative + Positive = Negative
-4b - 4b = -8b
15 - 6 = 9
-7k - - 2k
Negative + Negative = Positive
-7k + 2k = -5k
Put them all together:
0b + 9 - 5k
Simplify
-8b + 9 - 5k
I got the same answer as you (just in a different order)
Answer:
D, A, B
Step-by-step explanation:
The sign of the leading coefficient always tells you the end behavior on the right: positive = rises; negative = falls.
The degree of the polynomial tells you how the left- and right-end behaviors compare: even = they are the same; odd = they are opposites.
__
A) negative leading coefficient, even degree:
- falls to the left, falls to the right (D)
__
B) positive leading coefficient, odd degree:
- falls to the left, rises to the right (A)
__
C) negative leading coefficient, odd degree
- rises to the left, falls to the right (B)
