Answer:

The mistake is that 4x+x = 5x  not 4x

Step-by-step explanation:

4x + x = 30 –6

Combine like terms

5x = 24

Divide each side by 5

5x/5 = 24/5

x = 24/5

The mistake is that 4x+x = 5x  not 4x

There are 3 red and 9 blue counters in a box. A counter is chosen and then replaced. If you did this 144 times, how many times w
anygoal [31]
If you do it 144 times that is (3+9)*12
This means that 12 times 3 red and 9 blue counters will be chosen that means that 9 blue counters will be chosen 12 times. 9*12 is 108.
This means blue counters will be chosen 108 times.
This can be checked as 108/3 would give you the number of red counters which is 36 and 108+36 is 144

A rectangle as an area of 240 square ft the base is 15 what is the height of the rectangle
zhannawk [14.2K]

Answer:

16 ft

Step-by-step explanation:

Hi there,

The formula for the area of a rectangle is A = b*h.

So, let's start out by plugging in what we know.

240 = 15h

Now, solve for h by dividing both sides by 15

h = 16

So, the height of the rectangle is 16 ft

Hope this helps! Stay safe!

Question 10 (3 points)
Zinaida [17]

Answer:

$3,090.64

Step-by-step explanation:

We shall allocate a random letter to each value, with that I explain the formula.

Initial value of investment = $5,003.86  = P

Rate of interest = 3.7% = R

Compounding interval in a year = 365 = I

Total period = 13 years = T

Value of investment in compound interest formula shall be:

= P \times (1 + \frac{R}{(I})^{(I \times T)}

Now, putting values in the above equation:

= 5,003.86 \times (1 + \frac{0.037}{365}) ^{(365\times13)}

= $8,094.50

Thus, interest earned = Total value of investment on maturity - Initially invested amount

= $8,094.50 - $5,003.86 = $3,090.64
