Answer:
a = 18
Step-by-step explanation:
2(a-7)=a+4
Distribute 2 into left side: 2a -14 = a + 4
subtract a from both sides 2a-a-14 = a+4-a
Simplify: a - 14 = 4
Add 14 to both sides: a - 14 + 14 = 4 +14
Simplify: a = 18
If wanted, plug a into original to double check work:
plug in: 2 (18-7) = 18+4
do parenthesis first: 2 (11) = 18+4
do multiplication : 22 = 18+4
additions: 22 =22
a = 18 is correct.
Step-by-step explanation:
Given
( 6x² - x + 8 ) - ( x² + 2)
= 6x² - x + 8 - x² - 2
= 5x² - x + 6
It would be 56 mph. you need to divide 224 from 4 to get the unit rate
Answer:
5.907km
Step-by-step explanation:
- In the morning, Jax walked 2.783 km while taking care of the livestock.
- In the evening, Jax walked 3.124 km while taking care of the livestock.
The total distance Jax walked while taking care of the livestock today is the sum(or addition) of the distance which he walked in the morning and in the evening.
Total distance = 2.783+3.124
=5.907km
The total distance Jax walked today while taking care of the livestock is 5.907km
