Answer:

4

Step-by-step explanation:

First, you have to right out the equation, which is

3n + 18 = 30

To solve the equation, subtract 18 from both sides,

3n = 12

Then, divide both sides by 3

n = 4

Hope this helps!!

A $20,000 investment earned a simple interest rate of 5.4%. How much interest was earned in one year?
ICE Princess25 [194]

Answer:

The interest earned in a year was $1080.

Step-by-step explanation:

Since the money was invested at a simple interest rate, then the amount earned in one year is given by the following formula:

M = C*r*t

Where M is the amount earned, C is the amount invested, r is the rate of interest and t is the time elapsed. Applying the data from the problem, we have?

M = 20000*(5.4/100)*1

M = 20000*0.054

M = 1080

The interest earned in a year was $1080.

How many 8s go into 293 cause i cant work it out so far?
ratelena [41]
Try multiplying it
we know that 8 times 10=80 so multiply 80 by 2, then 3 then 4 untill you get close to that number so
80 times 2=160
80 times 3=240
80 times 4=320
this is over so it is more than 30 8's but less than 40 8's
so start from 320
subtract 293 from 320
320-293=27
divide 27 by 8
27/8=3 and 3/8
add that to 30

33 and 3/8 8's will fit

the teacher probably wants how many whole 8's can fit so get rid of the 3/8 and just put 33 8's
