Bobby has 24 pizza slices
he divided them among his friends and each friend got 3 pieces
how many friends did he have
so
24 divided by number of friends=3
24/y=3
multiply both sides by y
24y/y=3y
24 times y/y=3y
24 times 1=3y
24=3y
divide both sides by 3
24/3=3y/3
8=3/3y
8=1y
y=8
8 friends
Answer:
a) x = 260
b) g = 218
c) z = 30
d) h = 5
Step-by-step explanation:
a) 
Predict a number; let's say x = 225

Too low; try with a higher number; let's say x = 270

Too high, we're closer.
x = 260

--------------------------------------------------------------------------------------
b) 
let's say g = 230

Too high. Try g = 221

We're almost there. Let's try with g = 218

----------------------------------------------------------------------------------------
c) 
Let's try with z = 15

Too low; try a higher number. z = 30

--------------------------------------------------------------------------------------------
d) 
Let's try with h = 6

Too high; let's try with h = 5

Answer:
58
Step-by-step explanation:
Add up the angles inside the triangle that are given. All triangles = 180 degrees.
So the missing angle inside the triangle is 122 degrees.
The line is 180 degrees as well, so the angle we are looking for, DFG should be 58 degrees because 180-122 = 58
Answer:

Step-by-step explanation:
we know that
The length of a circle is equal to the circumference

where
r is the radius of the circle
In this problem we have

The length of semicircle is equal to
