Kerris reasoning that 4.2/5 is about 8 tenths because 4.2/5 is close to 40 tenths/5 is correct
<h3>How to interpret Kerris reasoning?</h3>
The quotient is given as:
4.2/5
Kerris reasoning is that
4.2/5 is approximately 0.8
We start by calculating the actual value of the quotient 4.2/5
Using a calculator, we have:
4.2/5 = 0.84
Approximate to the nearest tenth
4.2/5 = 0.8
This means that Kerris reasoning that 4.2/5 is about 8 tenths because 4.2/5 is close to 40 tenths/5 is correct

Answer:
C. –2x – 10 = –2(x + 5)
Step-by-step explanation:
Clearer choices:
2x + 10 = –2(x – 5)
–2(x + 5) = 2x – 10
–2x – 10 = –2(x + 5)
–2(x – 5) = –2x – 10
All choices have either:
–2(x – 5) for A and D
or –2(x + 5) for B and C
Simplify these expressions by <u>expanding</u> with the distributive property. Multiply the outside term "–2" with each term inside the brackets.
–2(x – 5)
= (–2*x) – (–2*5) Multiply each term by the coefficient
= –2x – (–10) Simplify the double negative to a positive
= –2x + 10 Expanded expression
This is not the same answer in A and D. They are not correct.
–2(x + 5)
= (–2*x) + (–2*5) Multiply each term by the coefficient
= –2x + (–10) Adding a negative is the same as subtraction
= –2x – 10 Expanded expression
This is the same answer for <u>option C</u>.
Therefore "C" is the answer.
The number is -3 because -3 minus 16 equals -19.
Answer: 7/12 of the beads are blue and green
Step-by-step explanation: To make both denominators of fraction 3/12 and 1/3 equal, you have to change both denominators to the lowest common denominator. Since the LCD (lowest common denominator) is 12 you have to multiply 1/3 by 4 to make the two denominators match.
1/3 x 4/4= 4/12
Then to find the total fraction of both green and blue beads on the necklace, you simply have to add the two fractions together.
4/12+3/12= 7/12
hope this helps :)
