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:
The answer to your question is below
Step-by-step explanation:
23.- According to the picture I can conclude that is an isosceles triangle,
then, 45° = 2 so
45° = x + 60
x = 45 - 60
x = -15
24.- This is also an isosceles triangle, then, 2 = 74
3x - 4 = 32 2x 74 = 148
3x = 32 + 4 180 - 148 = 32 = 3x - 4
3x = 36
x = 12
25.- This is an equilateral triangle, then,
60 = 7x - 10
60 + 10 = 7x
70 = 7x
x = 70/7
x = 10

Note the property for square roots in exponential form:
_____________________________________
→ ![\sqrt[a]{(b)^ c}](https://tex.z-dn.net/?f=%5Csqrt%5Ba%5D%7B%28b%29%5E%20c%7D)

; 
.}.
_____________________________________
As such, given:
→ ![\sqrt[4]{(15^7)}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%2815%5E7%29%7D)
