Solve each equation and show your work for all thema. n-3.4=2312.2

b. 1× =5.12
--
2

c. m + 2 = 7.8

d. 1.2 d = 6

Answers

a. n - 3.4 = 2312.2

Show Work: 2312.2
+ 3.4
----------
n = 2315.6

b. 1x = 5.12

Show Work: 5.12 divided by 1 would equal to 5.12 (Note: Anything times or divided by 1 would give you the same factor that you multiplied.)
x = 5.12

c. m + 2 = 7.8

Show Work: 7.8
- 2
-------
m = 7.6

d. 1.2 d = 6

Show Work: 1.2 divided by 6 would equal to 5.
d = 5

If 50 is 20% of a value what is that value

The answer would be 200 because it takes 20% 4x to get to 100% so 50x4=200

The value would be 250.

A number increases by 10%, and then decreases by 10%. Will the result be greater than, less than, or equal to the original number?

Answers

one way it so try

100
increase by 10%
10% of 100=10 so 100+10=110

then decrease by 10%
10% of 110=11 so 110-11=99

original number=100
is 99 greater than or less or equal the original?
99<100
it is less

Hey there! The answer would be less than because 10% of the first number would be more than 10% of the second number. If you don't know what I mean then look at this as a example. 100*0.10=10, of you subtract 100 by 10 you get 90, 90*0.10=9, you add 90 by 9 you get 99, 99 is less than 100 (99<100). Do you see what I mean. If not feel free to message me. :)

Ba^4•(2ba^4)^-3
The answer key says 1/8b^2a^8 but I don't understand how they got that.

Answers

$a^(4)b(2ab^(4))^(-3)$

$a^(4)b( (1)/((2a^(4)b)^(3)))$

$a^(4)b( (1)/((2a^(4)b)(2a^(4)b)(2a^(4)b)))$

$a^(4)b( (1)/(8a^(12)b^(3)))$

$(1)/(8a^(8)b^(2))$

$ba^4\cdot(2ba^4)^(-3)=(ba^4)/((2ba^4)^3)=(ba^4)/(8b^3a^(12))=(1)/(8b^2a^8)$

How would you solve -7x-4y=16

Answers

so one easy way is to make the equation equal to only one place holder so
-7x-4y=16
add 7x to both sdies
-4y=16+7x
multiply both sides by -1
4y=-16-7x
divide both sides by 4
y=-4-7/4x
subsitute values for x and get values for y
exg
if x=0 then y=-4
if x=1 then y=-5 3/7
etc
