Answer:
4 5/12
Step-by-step explanation:
We need a common denominator of 12
4 3/4 = 4 3/4 *3/3 = 4 9/12
1/3 *4/4 =4/12
4 9/12 - 4/12 =4 5/12

Answer:
That exterior angle is equal to 87 degrees.
Step-by-step explanation:
In order to find the measure of the exterior angle, we start by trying to find x. We can do this by adding up the 3 interior angles and setting them equal to 180. The first angle is equal to 43. The second angle is equal to x + 15. The third angle is equal to 180 - 3x (which we know because the angle and 3x is equal to 180). So we set equal to 180.
43 + (x + 15) + (180 - 3x) = 180 ----> Combine like terms.
238 - 2x = 180 -----> Subtract 238
-2x = -58 ----> Divide by -2
x = 29
Now that we have the x value, we can plug into the exterior angle measure to get the value.
3x = 3(29) = 87 degrees
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.
