Answer:
Step-by-step explanation:
The answers are:
A) {[(-15+5)×2+8]-32÷8}-(-7)
Calculate within parentheses: -16 - (-7)
Add and subtract (left to right): -16 - (-7) = -9
B) (5-2)³×2+[-4+(-7)]÷(-2+4)²
To solve this problem, you need to follow the steps of order of operations.
Calculate within parentheses:
* 2 + [-4 + (-7)] ÷ (-2+4)²
Calculate within parentheses:
*2 -11 ÷ (-2+4)²
Calculate within parentheses: 27 × 2 - 11 ÷ (-2+4)²
Calculate exponents: 27 × 2 -11 ÷ 4
Multiply and divide: 54 - 11 ÷ 4
Multiply and divide: 54 -
Add and Subtract: 
Convert improper fractions to mixed numbers:
= 
C) {-10-[12+(-3)²] + 3³}+3³}÷(-3)
Calculate within parentheses: -4 ÷ (-3)
Multiply and divide:
Simplify and convert improper fraction to a mixed number:
=

Answer:
x = 3
Step-by-step explanation:
MQ : MN = 5:6
MP : MO = 5:6
MQ/MN = 5/6
Hence, MP/MO = 5/6
(5+x)/(6+(18/5)) = 5/6
5+x = (5/6)(48/5)
5+x = 8
x = 3
These are problems like your answer to one problem = the number in the side of the thing
Answer:
42x^2 - 7x - 6x + 1
42x^2 - 13x + 1 for FOIL method
To solve for x
7x - 1 = 0
7x = 1
x = 1/7
6x - 1 = 0
6x = 1
x = 1/6
