When you multiply a number by 5 and then by 2 it is the same as multiplying by 10. multiplying by 10 means you add a zero to the end of the number so the digit in the ones column will be always be zero
Answer:
5x + 10y = 125
Step-by-step explanation:
Let :
Number of nickel = x
Number of dime = y
Nickel = 5 cent
Dime = 10 cent
Total value = $1.25
Total value should be converted to cent since both dime and nickel are both in cent
= $1.25 * 100 = 125 cents
Therefore,
5x + 10y = 125 cents
Answer:
98 = 2w + 2L,
L = 3w
Step-by-step explanation:
Use the perimeter formula:
2) Perimeter = 2w + 2L (where w is the width and L is the length)
Since the length is three times the width we can write:
L = 3w
We can substitue L with 3w:
Perimeter is equal to 98 so,
98 = 2w + 6w = 8w
W = 98/8
Therefore w is 12.25, and L is 36.75
Answer:
3
Step-by-step explanation:
to find the slope you do the formula
y2-y1 divided by x2-x1. (keep it in fraction form). it doesnt really matter what order you put the points as but keep it consistent
