Answer:
18
Step-by-step explanation:
(5/6)x – 4 = 11
(5/6)x = 11 + 4
(5/6)x = 15
5x = 15×6 = 90
x = 90/5 = 18
Answer:
(b) distance, y=20x, 480 mi
Step-by-step explanation:
As is often the case, the only self-consistent answer choice is the correct one.
__
The dependent variable is plotted on the y-axis, so is distance.
(x, y) = (2, 40) tells you y = 20x is an appropriate choice of equation.
In 24 hours, the dragonfly will fly y = 20(24) = 480 miles.
Answer: -6 = x
Step-by-step explanation: Start by distributing through the parentheses
on each side of the equation to get 5x - 40 = 7x - 28.
Now move your x's to the right and
numbers to the right and you get -12 = 2x.
Divide both sides by 2 and -6 = x
Answer:
2>x
Step-by-step explanation:
-6>10 - 8x.
Simplify it to get
-16>-8x
Simplify it again to get rid of the negatives. (Divide everything by -1)
16>8x
Simplify again
2>x
Answer:
m = 5.1
Step-by-step explanation:
