Answer:
C.
Step-by-step explanation:
In total, Sophie needs $230.40.
Let's form an equation. 230.40 = 12.80x
You'll need to divide both sides by 12.80 to get the variable, x, by itself.
18 = x
Therefore the answer is C.

Macy has bought 812 bananas. Jake has bought 83% of Macy's bananas. Karl bought three times the amount of Jake's amount at a local grocery store. Gary then proceeded to buy 29% of Karl's bananas. How much bananas does Gary have in total?
Answers
Answer:
586 bananas
Step-by-step explanation:
Macy - 812 bananas
Jake - (812 x 0.83) = 673.96 bananas
Karl - (673.96 x 3) = 2021.88 bananas
Gary - (2021.88 x 0.29) = 586.3452 bananas. The answer gets rounded down to 586 bananas because he can't have part of a banana

A drill is used to dig down into the earth. After 2 hours, the drill is 12 meters below the surface. After 5 hours, the drill is 30 meters below the surface. Which equation represents the depth of the drill in meters, y, after x hours of drilling?A line passes through the origin and (4, 5). Which point is also on the line?
Answers
6y = x
Step-by-step explanation:
All that equation is saying is that for every 1 hour drilled (x), 6 meters (y) are drilled.
y = distance in meters
x = time
12y = 2x
12y/2 = 2x/2
6y = x
30y = 5x
30y/5 = 5x/5
6y = x

Yolanda is filling her bathtub. The table shows the number of gallons of water in the bathtub at different times since she started filling it. Time (minutes) 1, 1.5, 2 Water (gallons) 16.50, 24.75,33. Now find the constant of proportionality (in gallons per minute) for the second and third rows of the table. Show your work.
Answers
Answer:
K= 16.5 gallons per minute
Step-by-step explanation:
Time t (minutes) Water g (gallons)
For t= 1, g= 16.50,
for t= 1.5 ,g= 24.75
For t= 2,g= 33
Let the function be
Gallons g= k(time t)
Where k is the constant of proportionality
16.5= k(1)for when t= 1
24.75= k(1.5) ..for when t= 1.5
Solving gives
8.25=k(0.5)
8.25/0.5= k.
16.5 = k
K= 16.5 gallons per minute

X+Y+W=180
(3x-5)+90+2x=180
5x+85=180
5x=95
x=19
Answer:
Angle Y is a right angle, it’s 90 degrees. Angle W is 2x, because it’s opposite angles on a single line with intersecting parallel lines. Triangles have 180 degrees, so adding up all sides creates the equation to solve:
X+Y+W=180
(3x-5)+90+2x=180
5x+85=180
5x=95
x=19
