<span>Using whole numbers, fractions, and decimals, these are the eight addition equations that have the sum of 10
</span>1. 5+5=10
2. 1 1/2 + 8 1/2 =10
3. 2.9+7.1=10
4. 6 1/3 + 3 2/3 =10
5. 4 3/5 + 5 2/5=10
6. 9.01+.99=10
7. 3.72+6.28 = 10
8. 8 8/9+ 1 1/9=10
For this case, the first thing we must do is define variables.
We have then:
x: number of checks.
y: total cost.
We now write the linear function that represents the problem.
We have then:

Then, Jerome issues 10 checks in a month.
Therefore, we evaluate the function for x = 10.
We have then:
Answer:
a monthly checking account will cost him about:
y = 12.5 $
Answer:
A = 8π cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 8 , then r = 8 ÷ 2 = 4
The area of half a circle is then
A =
π × 4² =
× π × 16 = 8π cm²
The area is 1. Hope this helps.:)
