Answer:
Point Q = (3.6, 1.4)
Step-by-step explanation:
The 4:1 ratio should first be changed to 4/5.
y2-y1= 2+1 = 3 which as a fraction is 3/1, now multiply that which the earlier fraction 4/5 to get 12/5 = 2.4
x2-x1= 4-2= 2 which as a fraction is 2/1, do the same as earlier, multiply by 4/5 to get 8/5 = 1.6
now add these to A to get point Q
2+1.6= 3.6
-1+2.4=1.4
Point Q = (3.6, 1.4)
Answer:
Better deal at Store B.
Step-by-step explanation:
The key to understanding this problem lies in recognizing that 16 ox = 1 lb, which leads to 64 oz = 4 lb.
Find and compare the two unit costs:
Store A:
$11.99
---------- = $0.20/oz
60 oz
Store B:
$11.99
------------ = $0.19/oz
64 oz
The 4-lb bag available at Store B has the lower unit cost and is a better deal there.
Answer:
x = 31
Step-by-step explanation:
x + x + 28 = 90
2x + 28 = 90
2x = 62
x = 31
Answer:
In your equation, put 3 where x is, and -1 where y is. If you get a true statement, like -8 = -8, or 69 = 69, then (3, -1) is a solution. If you get a false statement, like 9 = 21 or 10 = 420, then (3, -1) is not a solution.
