Answer:
7-16x=10. I'm sorry I'm not good at math but it never hurts try, right?
Step-by-step explanation:
Multiply the parentheses first which would give you
8-6x+10x-15.
Next add 6x+10x which would give you
8-16x-15.
Then subtract 8-15 which would give you
7-16x=20-5x2. Then work the problem from there.
7-16x=20-10.
7-16x=10.
Answer:
b. $2.50
Step-by-step explanation:
Let us take a step by step approach by simplifying each sentence:
Sentence 1: Hector works 12 hours per week at a part-time hours per week at a part-time job
Number of hours worked per week = 12hours
Sentence 2: His original pay rate was $8.00 per hour. but he recently received a raise of x dollars per hour
Pay per hour is 8hr, a raise of x gives 8 + x
Sentence 3: New total wage = 12(8+x)
Sentence 4: Amount earned last week = $126
New total wage = Amount earned last week
12(8 + x ) = 126
96 + 12x = 126
12x = 126 - 96
12x = 30
x = $2.50
Amount of raise is $2.50
Answer:
y = 2
Step-by-step explanation:
Given
y + (4 - 2y) = 2 ← remove parenthesis on left side
y + 4 - 2y = 2, that is
- y + 4 = 2 ( subtract 4 from both sides )
- y = - 2 ( multiply both sides by - 1 )
y = 2
Answer:
1. TRUE
2. False
3. TRUE
4. False
5. TRUE
6. False
Step-by-step explanation:
1. 6859^(1/3) = 19 = ∛(19^3)
__
2. 2197^(1/3) = 13 ≠ 9·2
__
3. 8000^(1/3) = 20 = 10·2
__
4. 9261^(1/3) = 21 ≠ 13
__
5. 3375^(1/3) = 15 = 5·3
__
6. 5832^(1/3) = 18 ≠ 3·7
A² + b² = c²
Where a and b are the legs and c is the hypotenuse
So, plug in 10 for one of the legs and 24 for the other leg
c will be left blank because that is what you are trying to find, the hypotenuse
10² + 24² = c²
100 + 576 = c²
676 = c²
Take the square root of both sides of the equation to isolate c
√676 = √c²
Square of c and the square root cross out on the right
Take the square root of 676
c = 26
So, the length of the hypotenuse is 26 centimeters
