Add up all the numbers the divide by the amount of numbers in the set.
1199/11 = 109
B. 109 answer
Answer:
8 one-dollar bills
3 five-dollar bills
2 ten-dollar bills
Step-by-step explanation:
Let x = # of one-dollar bills, y = # of five-dollar bills, and z = # of ten-dollar bills. Total amount in the wallet is $43, so the first equation would be 1x + 5y + 10z = 43. Next, there are 4 times as many one-dollar bills as ten-dollar bills, so x = 4z. There are 13 bills in total, so x + y + z = 13
x + 5y + 10z = 43
x = 4z
x + y + z = 13
x + 5y + 10z = 43
x + 0y - 4z = 0
x + y + z = 13
5y + 14z = 43
-y - 5z = -13
5y + 14z = 43
-5y - 25z = -65
-11z = -22
z = 2
x = 4z
x = 4*2 = 8
x + y + z = 13
8 + y + 2 = 13
10 + y = 13
y = 3
Answer:
y = x
Step-by-step explanation:
We can use slope-point form.
(y-y1) = m(x-x1)
m is a slope. If the line is parallel than slopes are the same.
y = x + 4, for this line slope = 1, so for line we have to find slope is also 1.
(y-y1) = m(x-x1)
m=1, x1 = 2, y1 = 2
(y - 2) = 1(x-2)
y - 2 = x - 2
y = x
[(21 + 6) - 32] : 9.2 = (27 - 32) : 9.2 = -5 : 9.2 = -46
