16x + 9 = 9y-2x Add 2x to both sides
18x + 9 = 9y Divide both sides by 9
2x + 1 = y Switch the sides to make it easier to read
y = 2x + 1
Answer:
$ 150
Step-by-step explanation:
Given:
Cost price of a microwave = $105
Discount % = 30
Question asked:
what was the price of the microwave before sale = ?
Solution:
Let the price of the microwave before sale =
Price before sale - 30 % discount = cost price of microwave (by Javier)
Multiplying both side by 100
Dividing both side by 70
x = price of the microwave before sale = $ 150
Thus, price of the microwave before the sale = $150
Answer:79°
Step-by-step explanation:
Garden
max area is if the sides are as equal as possible
so he should try to make a square (ideal is a circle, but barn walls are normally straight)
squaer perimiter=4 times legnth of 1 side
perimiter=amount of fencing=80
80=4s
divide 4
20=s
one sides=20
area=legnth times width
in squaer, legnth=width
20=legnth
20=width
area=20 times 20=400
dimetions are 20ft by 20ft to give 400ft^2
(fun fact, if it were a circle, the area would be about 509.5ft^2)
answer is 20ft by 20ft and area=400ft^2
Answer:
mean-8.167
median -8
there is no mode
Step-by-step explanation:
mean 2+5+7+9+11+15 = 49
49÷6=8.166666667
median its the middle number which is 7 and 9
7+9=16÷2 = 2
and the mode is the most frequently repeated number ....and non is repeated ..
