68+32=100 he used a $100 bill
Step-by-step explanation:
Each person's donation ratio is:
Donation 1 is 4/15 of 75
Donation 2 is 4/15 of 75
Donation 3 is 7/15 of 75
4/15(75) = 5 * 4 = 20
7/15(75) = 5 * 7 = 35
Each person's donation amount is:
$20
$20
$35
Check out work:
20 + 20 + 35 = 75!
Answer:
5x⁷ is a monomial of degree 7
Answer:
y = 2x
Step-by-step explanation:
Note the relationship between x and y, that is
x = - 42 → y = - 84 ← that is y = 2x
x = - 14 → y = - 28 ← that is y = 2x
x = 14 → y = 28 ← that is y = 2x
x = 42 → y = 84 ← that is y = 2x
Thus the linear equation is y = 2x
