9 7/8 written as a decimal is 9.88
Work: So, The first thing I did was 9 (Whole Number) times the Denominator. After the Multiplication, I had gotten 72. I added 72 by the numerator which is 79. Then, I divided 79 by the denominator, and I had gotten 9.875, and I rounded it up to 9.88
I hope this helps, and you get this question correct. :)
Answer:
21 windows
Step-by-step explanation:
collen family plans to paint the windows of their house. her father will paint twice as many windows as her mother, and collen and her 2 brothers will paint an equal number of the rest of the windows. Colleen decided to do her own share and her mother's share and paints 7 window, which is one less than her father's share. how many windows are in their house?
Answer: Let the number of window Collen father would paint be a while that of her mother be b. Since her father will paint twice as many window as her mother, therefore the number of windows painted by the father a = 2b
Let the number of windows that would be needed to be painted each by Colleen and her 2 brothers be c because they would paint the equal number of windows.
The total number of windows to be painted = 2b + b + c + c + c = 3b + 3c = 3(b + c).
Collen painted 7 windows as her mother and her own share which is one less than the fathers share. Therefore b + c = 7.
Also the fathers share a = 2b = 7 + 1 = 8 windows. Therefore b = 4 which is the mother share
Therefore the total number of windows = 3(b + c) = 3(7) = 21 windows
3b + 3c = 21
3(4) + 3c = 21
12 + 3c = 21
3c = 21 - 12
3c = 9
c = 3 which is collen and her brothers share
Answer:
y = 
x
Step-by-step explanation:
slope-intercept form: y = mx + b
Given: slope(m) = , point (4, -3)
We already have the value of m, but we need to find the value of b. To do this, input the given values of the slope and the point into the equation:
-3 = (4) + b
Solve for b:
-3 = (4) + b
-3 = -3 + b
0 = b
The value of b is zero. We can now write the equation:
y = x + 0
y = x
The equation written in slope-intercept form is: y = x
Answer:
Range
Step-by-step explanation:
The range of a graph tells you <u>all of the possible y-values</u> for it.
There is also the domain, which tells you all of the possible x-values.
For example, if you have this relation, that only has these points:
(1, 2) (2, 4) (3, 6)
Then the range is {2, 4, 6}. This means the "y" can ONLY be the numbers stated here.
The domain would be {1, 2, 3}.
