Answer:
Step-by-step explanation:
slope of line through (0,0) and (4,3) =(3-0)/(4-0)=3/4
eq. of line is y-0=3/4(x-0)
y=3/4 x
put x=4
y=2
2=3/4×4
2=3
which is true if 2<3
2<3
so y<3/4 x
There are 16 girls and 20 boys....the ratio of girls to boys is 16/20 which reduces to 4/5 or 4:5 or 4 to 5.
Remark
The easy way to do this is to change 5/8 to a decimal and worr y about changing it back to a fraction if you need to.
15 5/8 = 15.625 The easy way to find 5/8 is to use your calculator. 5 ÷ 8 = on most calculators.
You want 12 of these
1 leg is 15.625 inches long.
12 legs = x
1/12 = 15.625 / x Cross multiply
x = 12 * 15.625
x = 187.5 inches
Just how many feet is that? Divide by 12 to get the number of feet 187.5 / 12 =
15.625 feet.
Usually 2 by 4s are 8 or 12 feet long. For 8 feet you will need 2 of them and for 12 feet unfortunately you will need two as well.
Answer:
y=-1.5x-4
Step-by-step explanation:
-3y=-2x+13
3y=2x-13
y=2/3x-13/3
Slope: -3/2
5=-6(-1.5)+b
5=9+b
b=-4
