Answer:
C. 3 : 5
D. 24 : 40
Step-by-step explanation:
Select two ratios equivalent to 6 : 10
Checking all options
A. 20 : 12
20 / 12
= 10 /6
= 10 : 6
B. 32 : 50
= 32 / 50
= 16 / 25
C. 3 : 5
3 / 5
= 6 / 10
3/5 is equivalent to 6 / 10
D. 24 : 40
24 / 40 = 12 / 20
= 6 / 10
= 6 : 10
Options C and D are correct
Given that the steps are not shown, I am going to show you all the rigtht steps in detail and so you will be able to compare and tell which step from you list contains an error:
1) Traslation into algebraic language:
<span>“three less than the quotient of a number squared and nine, increased by eight”
3 - (n^2) / 9
2) Evaluate it when n = 6 (replace the value of n)
3 - (3^2) / 9
3) solve the parenthesis
3 - 9/9
4) divide 9/9
3 - 1
5) Subtract
2
</span>
Now you know all the steps and can tell which of the steps on the list is wrong.
First write the inequality: 15

4.75x +3.50
Then to solve, first subtract 3.50 from both sides to get:
11.50

4.75x
Then divide by 4.75 to get 2.42, and since you can't buy .42 of a bag of fruit, you round down. So your final answer would be 2 bags of fruit.

Answer:
1
Step-by-step explanation:
We will consider only the last digit multiplication and the pattern.
When we multiply 843,219 with 843,219, we have
9 * 9 = 81 [1 is important]
1 * 9 = 9
9 * 9 = 81 [1 is important]
So when we multiply them out with each other, we have a pattern of
9, 1, 9, 1 ... goes on
So if we multiply 100 times, what will be the last digit of the series 9, 1, 9, 1 .... it will be 1
hence, last digit is 1
