Answer:
The variable Y represents the number of meters of string in the third yoyo
Step-by-step explanation:
In this equation y stands for the unknown variable. The equation tell you that hope made 3 different yo-yos so the number of yo-yos hope made isn't unknown, meaning, it cant be the first answer. The problem also tells you that hope used a total of 4 meters of string which means that the total number of string used isn't the unknown variable. The number of meters of string in the third yo-yo is the only number that isn't. This makes the number of sting used in the third yo-yo the unknown variable, making it y.
Total cost= (24 times 4)+(10 times 2)
96 + 20 = 116
cost: $116
Answer:
x = 1.25
Step-by-step explanation:
<1 and <2 are corresponding angles and if the lines are parallel, corresponding angles are equal
<1 = <2
20-8x = 30-16x
Add 16x to each side
20-8x+16x = 30-16x+16x
20 +8x = 30
Subtract 20 from each side
20+8x-20 = 30-20
8x= 10
Divide by 8
8x/8 = 10/8
x = 5/4
x = 1.25
