-1-4= 5-3x+4xPlease help me! This is kind of confusing, and I don't really understand.

pleeeeeeeease help me im so confused!!! m has put $500 into a savings account that pays her 2% annual interest, how much will her $500 be worth after 2 months?

Answers

so m puts in 500 dollars
it's 2% or 2/100 in a year or 12 months
so in 2 months or 1/6 year
she will get 2/600=0.33%
so 0.33% of 500=1.6666
1.6666+500=501.666
that's great considering that after 4 years saving at wells fargo I only got 16 cents interest

first form an equation: 500+(500*0.02x)=y
2% is the annual interest so 2 months would be 1/6 (of 2%.
2% of $500 is $10. 1/6 of of $10 is $1.67.
Add that to your initial $500, and you get $501.67, so your $500 dollars will be worth $501.67 after 2 months

Can anyone help me with this one? i don't understand this worksheet at all.

12^-6/12^7

When dividing the only thing you do is subtract the exponents from each other.

-6-7

In this case, you have to subtract a number from a negative. -6-7 would actually be -6+-7.

-6+-7= -13

12^-13 is the final answer

For each of these three equations, determine whether there are any solution(s). If there are solutions, say what they are and show how you found them. If there aren't solutions, explain why not. EXPLAIN!!! I will mark as brainliest!!!(a) x/3 + x/4 + x/5 + = (2x)/3 + (2x)/4 + (2x)/5

(b) y/3 + y/4 + y/5 = y/3 + y/4 + y/5 + 1

(c) z/3 + z/4 + z/5 = z/4 + z/5 + z/6 + 1$

Answers

For (a)
The resulting equation is
47x/60 = 47x/30
and the solution is 0

For (b)
The resulting equation is
47y/60 = 47y/60 + 1
which is reduced to
47y/60 - 47y/60 = 1
0 = 1 (impossible)

For (c)
The resulting equation is
47z/60 = 37z/60 + z
and the solution is 6

A 35 meter length of cable is cut into pieces that measure 1.25 meters each.into how many pieces is the cable cut

Answers

The number of pieces that the cable is cut is 28.

What is Division?

Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number.

Total length of the wire = 35 meters

Length of each cut piece = 1.25 meters

Number of pieces can be found by dividing the total length of the wire by the length of each piece.

Number of pieces of wire = 35 / 1.25 = 28

Hence the number of pieces of cable is 28.
