Answer:
x=1
Step-by-step explanation:
14=12x+2
subtract 2 from both sides
12=12x
divide both sides by 12 and you get x=1
Answer:
D
Step-by-step explanation:
the percentage increase is found using
percent increase = 
× 100%
increase = 166 - 135 = 31, hence
percent increase = 
× 100% = 22.96 ≈ 23% → D
Answer:
She earned 11 after completing 5 chores
Step-by-step explanation:
<em>We are shown a scatter plot and the equation of best fit line. The eqaution explains the general trend of the scatterplot. Using the equation we can find the money earned for 5 chores</em>
Amount of money earned, y = 2x + 1 ---(1)
Chores Completed, x = 5
put x = 5 in eq(1)
y = 2(5) + 1
y = 11
Hello there! Provided the information, we know that the nearest multiple of 8 and 9 has to be greater than 50. 8 and 9 do not go into 50.
$9 • 6 hours = $54
$8 • 7 hours = $56
There are 60 minutes in an hour, so we can multiply accordingly:
60 minutes • 6 hours = 360 minutes
60 minutes • 7 hours = 420 minutes
Your final answers are:
It will take John 360 minutes to earn $50.
It will take Amber 420 minutes to earn $50.
(P.S. It takes Amber one more hour to earn $50 than it does for John to earn $50.)
Hope this helps!
Answer:
a. y = -x
b. Area = xy
c. x = -y
Step-by-step explanation:
a. The perimeter of the garden is the distance all the way around, in this would be x+y+x+y, or 2x + 2y. To solve for y, we’re trying to isolate it on one side. We need to subtract 2x to get 2y = -2x. Divide by 2 to get y = -x.
b. Area is length times width, so x • y, or xy.
c. To express in terms of x, we can take the equation y = -x and multiply it by -1 to get x = -y
