There are 4 equal slices because 25 to 25 to 25 to 25 =100
Simple...
you have: If this cable installer charges $42.50 per hour plus a fixed $45 service charge..then set your equation..using-->>
y=mx+b
How much would the cable installer charge for 5 hours?
y=42.50(5)+45
y=212.50+45
y=$257.50
Thus, your answer.
Suppose robbie buys x scones then according to the question.....cameron will have x+y
..lou's will have (x+y)+y=x+2y ...
Tom=x+3y....
Charlie=x+4y.....
now as we know that the combines scones of robbie and Cameron is 3/7 times of total of louis.....
x+(x+y)=3/7 (x+3y+x+2y+x+4y)....solve this ...and this will be your 1st equation...and second equation will be x+x+2y+x+3y+x+4y=60.......And solve both equation simultaneously and then you will have the answers of x and y the put the values of x and y in each of the equation that i have written above for each person
Answer:
= 22.5°
= 67.5°
Step-by-step explanation:
Let’s create a system of equations for
and
.
Complementary angles are two angles that add up to 90°, so ![f+g=90](https://tex.z-dn.net/?f=f%2Bg%3D90)
Also,
is thrice of g: ![f=3g](https://tex.z-dn.net/?f=f%3D3g)
We can now substitute
in
for
.
![3g + g = 90\\\\4g = 90\\\\g=22.5](https://tex.z-dn.net/?f=3g%20%2B%20g%20%3D%2090%5C%5C%5C%5C4g%20%3D%2090%5C%5C%5C%5Cg%3D22.5)
Now, we can find
by substituting
into either equation.
![f + 22.5 = 90\\\\f = 90-22.5\\\\f = 67.5](https://tex.z-dn.net/?f=f%20%2B%2022.5%20%3D%2090%5C%5C%5C%5Cf%20%3D%2090-22.5%5C%5C%5C%5Cf%20%3D%2067.5)
Hope this helped!
