Answer:
r=3
Step-by-step explanation:
The diameter is double the radius. So, divide by 2.
The formula of the line is
y=mx + b
The likes goes through the point (0,0)
that means that y-int = 0, b=0
y=mx
So we need to find only slope.
Answer:
1/12
Step-by-step explanation:
There are 4 clothing choices and 3 colors.
4x3=12
This means you have a 1 in 12 chance of getting an orange hat.
This presupposes that there are EQUAL numbers of pieces and colors. (111 of each).
No values of z make the equations true.
Let m and s be the number of math and sociology books sold respectively.
m=s+88 we are also told that:
m+s=426, using m found above in this equation gives you:
s+88+s=426 combine like terms on left side
2s+88=426 subtract 88 from both sides
2s=338 divide both sides by 2
s=169, since m=s+88
m=169+88=257
So 257 math and 169 sociology textbooks were sold.
