q + d = 80
.25q + .10d = 14.45
q. + d= 80
25q + 10d = 1445
-10q. - 10d = -800
25q + 10d = 1445
15q. = 645
q = 43 quarters
43 + d = 80
d= 37 dimes
Answer:
B= (-1, 7)
Step-by-step explanation:
Midpoint formula is X1 plus X2, then divided by 2. So, because the midpoint is given you work backwards. So for the x value do (-3 + x) divided by 2 equals -2 and solve for x and you do the same thing for the Y value
Answer:
The answer to your question is letter D
Step-by-step explanation:
Data
P1 (3, 10)
P2 (-1, 6)
Process
1.- Calculate the midpoints
Xm = (x1 + x2)/2
Ym = (y1 + y2)/2
x1 = 3 y1 = 10
x2 = -1 y2 = 6
Xm = (3 - 1)/2
= 2/2
= 1
Ym = (10 + 6)/2
= 16/2
= 8
2.- Write the coordinates of the center
C = (1, 8)
Answer:
(2,1)
Step-by-step explanation:
X=2 and y=1
Answer:
96
Step-by-step explanation:
12 ÷ 3 = 4 (therefore he is saving $24 four times in 12 weeks)
24 × 4 = 96
