Answer:
21 windows
Step-by-step explanation:
colleen's family plans to paint the windows of their house. her father will paint twice as many windows as her mother, and Colleen 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 Colleen father would paint be x while that of her mother be y. Since her father will paint twice as many window as her mother, therefore the number of windows painted by the father x = 2y
Let the number of windows each painted by Colleen and her 2 brothers be z since they would paint the same number of windows. The total number of windows to be painted = 2y + y + z + z + z = 3y + 3z = 3(y + z).
Then number of windows needed to be painted by Colleen and her mother is given as z + y. Since Colleen painted 7 windows as her share and her mother share i.e. y + z = 7
Therefore the total number of windows = 3(y + z) = 3(7) = 21 windows
Answer :- Just try area/2 or half the area of the triangle
Nothing to "solve" here. Just graph this absolute value function.
Note that if x=2 we get y = -4. Thus, (2,-4) is the vertex. Plot this point.
Now, starting from (2, -4), draw a line at a 45 degree angle to the horizontal.
Then draw a corresponding line on the other side of the y-axis. You're done!
Answer:
-4y-7 i think
Step-by-step explanation:
sorry if im wrong but im pretty sure you combine -4 and -3, and -4 plus -3 is just -4 -3 so -7
Assuming the pyramid is numbered 1 to 4 and there are 3 colors on the spinner, the probability of landing on 3 and blue is 1/12.
To find the combined probability, we just multiply the 2 individual probabilities.
P(3) = 1/4
P(blue) = 1/3
1/4 x 1/3 = 1/12
