Okay. So 90 yds was cut from the 230 yd yarn. 230 - 90 = 140. 1/2 of 140 is 70. 230 - 70 = 160. The yellow yarn was 160 yds longer than the blue yarn at first.
2(3x +x)=30
8x = 30
x =3.75 = width
3x = 11.25 = length
Answer:
1) y=6
Step-by-step explanation:
The equation y=mx+b is called slope-intercept because it tells us the slope,m, and y-intercept ,b.
The equation y=a is a horizontal line and goes through a on the y-axis. Horizontal lines have a slope of zero.
The equation x=b is a vertical line and goes through b on the x-axis.
Vertical lines have an undefined slope.
1) y=6 is horizontal so it's slope is 0
2) x=6 is vertical so it's slope is undefined
3) y=2x has slope 2
4) x+y=1 can be put into the form y=mx+b to determine the slope.
Subtract x on both sides:
y=-x+1
The slope is -1.
Step 1. Divide by the numbers 0.25 (1 divided by 4):
0.25 x +2=5 divided by 8x-5
Step 2. Divide the by the numbers 0.625 (5 divided by 8):
0.25 x +2=0.625x-5
Answer: 0.25 + 2= 2.25
Please correct me if I'm wrong, hope I could help! :)
