Answer:
Step-by-step explanation:
P = pigs D = ducks
P + D = 17
P = 17 – D
4P + 2D = 50 because pigs have 4 feet
and ducks have 2 feet.
4(17 – D) + 2D = 50
68 – 4D + 2D = 50
.68 – 2D = 50
–2D = –18
D = 9
P = 17 – D
P = 17 – 9
9 = 17 – D
D = 8
1024 is the answer to this problem.
Step-by-step explanation:
How many mushrooms did she gather every hour, if she gathered 7 more mushrooms in the second hour than in the first hour, and 6 more in the third hour than in the first hour? = 8.
3 consecutive even integers.....x, x + 2, and x + 4
1/2(x + 2 + x + 4) = 65....multiply both sides by 2, canceling out 1/2
x + 2 + x + 4 = 65 * 2
2x + 6 = 130
2x = 130 - 6
2x = 124
x = 124/2
x = 62
x + 2 = 62 + 2 = 64
x + 4 = 62 + 4 = 66
so ur numbers are : 62,64,66 <==
