This should be simple, add the Amounts of snow for the first week
4.32 + 6.86 = 11.18
-------------------------------------------------------
The subtract the amounts of snow from each week
11.18 - 7.89 = 3.29
----------------------------------------
C.) 3.29 is your answer
Answer:
<h3>
R(-1, -9)</h3>
Step-by-step explanation:
When we reflect over x-axis then the x-coordinate doesn't change and the y-coordinate changes its sign
in means if R = (x, y) then R' = (x, -y)
so we have:
x = -1 and -y = 9
y = -9
which gives R = (-1, -9)
Answer:
plain dresses = 25
dyed dresses =125
Step-by-step explanation:
number of plain dresses - x
number of dyed dresses - y
X + Y = 150 -------- (1)
50X + 70Y = 10000 ------------ (2)
(2)/50
X + 7/5 Y = 200 ---------- (3)
(3) - (1)
0 + 7/5Y - Y = 50
2Y = 250
Y = 125
; X = 25
The first equation is x+x+3x+3x. You know that the perimeter is w+w+l+l, so, you can simply substitute the width, x, and the length, 3x (Three times the width).
The second equation is 8x. This comes from the first expression. If you have three of something plus three of the same thing plus one of the same thing plus one of the same thing, you have 8 of that thing. In other words, combine like terms.
I hope this helped! :) if it didn't, comment please!!!
