How do I solve these? thanx in advance

Answers

Answer 1

Answer: 7. Subtract 5.7 from both sides to get the variable on one side. (f=2)
8. Subtract 5.52 from both sides to get the variable on one side. (f=5)
9. Add 3.77 to both sides so the variable will be on one side.
10. Add 10.58 to both sides.
11. Divide by 2.2 on both sides. 2.2b/2.2 will leave you with the variable b. 8.8/2.2=4; b=4.
12. Divide by 2.5b on both sides. 2.5b/2.5 leaves b. 10/2.5= 4; b=4.

Answer 2

Answer: 7) minus 5.7 from both sides to get
f=1

8) minus 5.52 from both sides to get
f=5

9) add 3.77 to both sides to get
f=11.1

10) add 10.58 to both sides to get
f= 21

11) divide both sides by 2.2 to get
b=4

12) divide both sides by 2.5 to get
b=4

hope this helps!

Im going to use subtraction

How can you tell when a pattern shows counting on by tens?

Answers

Answer:
The difference between successive terms is 10

Explanation:
To know the factor by which a certain pattern is increasing/decreasing, you need to subtract its successive terms.

If the subtraction gives you 10, this means that the pattern is increasing by 10

Examples:
10, 20, 30, 40, 50, .....
20 - 10 = 10
30 - 20 = 10
40 - 30 = 10
50 - 40 = 10
The difference between each two successive terms is 10. This means that each time we add 10 to the number we have in order to get the next one.
Therefore, this pattern is increasing by 10

37, 47, 57 , .....
47 - 37 = 10
57 - 47 = 10
The difference between each two successive terms is 10. This means that each time we add 10 to the number we have in order to get the next one.
Therefore, the pattern is increasing by 10

Which decimal is equal to 1/5

A. 0.2

B. 0.15

C. 0.1

D. 1.50

Answers

If you do 1 literally divided by 5, because that's basically what it's asking for, you get .2, so it's A

1/5 can also be replaced as 20/100 you just multiply the denominator and numerator by 20. I think it is easier this way because decimals are out of 100 so if you can find an equal fraction that is out of 100 for the denominator the numerator can be turned into decimal form
