Answer:
y = 3x
Step-by-step explanation:
Li is making beaded necklaces where he uses 3 beads per inch of the necklace length.
We have to write an equation to find the number of beads that Li needs for each necklace, where x is the length, in inches, of the necklace.
Hence, we can write the equation for number of beads as y = 3x ( Answer )
The length of XY is 17 units
Step-by-step explanation:
A mid-point of a line segment
- Divide it into two equal segments
- Each segment is half the length of it
∵ X is the mid-point of WY
∴ WX = XY
∴ WX =
WY and XY =
WY
∵ WX = 3x - 1
∵ WY = 10x - 26
- By using the rule WX =
WY
∴ 3x - 1 =
(10x - 26)
- Simplify the right hand side
∴ 3x - 1 = 5x - 13
- Add 1 to both sides
∴ 3x = 5x - 12
- Subtract 5x from both sides
∴ -2x = -12
- Divide both sides by -2
∴ x = 6
∵ XY = WX
∵ WX = 3x - 1
∴ XY = 3x - 1
- Substitute the value of x in the expression of XY
∴ XY = 3(6) - 1
∴ XY = 18 - 1
∴ XY = 17 units
The length of XY is 17 units

Answer:
the seventh grader because the eighth graders got 58 which is more than 50 so the 7th grader would get the pts
Step-by-step explanation:
He bought 45 bars of chocolate.
1/5 x 45 = 9
He ate 9 bars on Tuesday.
45 - 9 = 36
He had 36 bars left.
1/12 x 36 = 3
He ate 3 bars on Wednesday
36 - 3 = 33
He had 33 bars left.
