Answer:
The man has 6 GHc20.00 notes and 4 GHc10.00 left
Step-by-step explanation:
Given
Amount = 3 GH¢50.00, 7 GH¢20.00 and 5 GH¢10.00
Spendings = GH¢80,00
Required
Determine how many GH¢20.00 and GH¢10.00 notes left
The amount he has can be represented as:


This can be represented as:

Represent:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
So, we have:





Subtract the spendings from the total to get amount left


Collect Like Terms


Recall that, we have represented:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
<em>This means that, the man has 6 GHc20.00 notes and 4 GHc10.00 left</em>
There are 12 inches in a foot, so divide 1590 by twelve. It equals 12.5. That is 12 feet and 5 inches!
Answer:
D. 0.77
Step-by-step explanation:
Jonas builds a snow fort. He tells his friends it is 0.8 meters tall inside, but he rounded the height to the nearest tenth. Which could be the height of the snow fort before Jonas rounded it?
Check all options by rounding to the nearest tenth
A. 0.89 m
= 0.9 m
B. 0.74 m
= 0.7 m
C. 0.85
= 0.9 m
D. 0.77
= 0.8 m
Note: Digits 0 - 4 are rounded down while digits 5 - 9 are rounded up
Rounding to the nearest tenth means having one digits after the decimal point
Answer : The incorrect step is, (A) step 1: -10 + 6x > 8
Step-by-step explanation :
The given expression is:

Now solving this expression step by step.
First -4 distributed over parentheses.

Now solving bracket term, we get:

Now taking like terms together, we get:



Now multiplying this expression by (-1), we get:

Thus, the incorrect step is, (A) step 1: -10 + 6x > 8
