-3.25, because if you work backwards and do the math you’d divide 7 and 4 which equals 1.75 then subtract that by 5

Let's make an equation. T will be the number.
(T+5)/4=7
Let's multiply both sides by 4 to get T by itself.
T+5=28
Subtract 5 from both sides.
T=23
Your number is 23.

When 5 is subtracted from the square of a number, the result is 4 times the number. Find the negative solution.

wariber [46]

Answer:

-1

Step-by-step explanation:

You can write it as...

$x^{2} -5=4x$

Carry the 4x

$x^{2} -4x-5=0$

Then use the quadratic formula to solve, since you want to find the negative solution, you don't need to find the positive solution, so we will have

$(4-\sqrt{16+20}) /2=\frac{4-6}{2}=\frac{-2}{2} =-1$

Therefore our answer is -1

field biologist collects 220 butterflies and moths. He collects 4 butterflies for every moth. How many butterflies and how many

ki77a [65]

Answer:

The number of butterflies he collects = 176

The number of moth he collects = 44

Step-by-step explanation:

This question has to do with ratio.

We are told in the question that:He collects 4 butterflies for every moth.

Hence, the ratio of

Butterflies : Moth

4 : 1

Sum of the proportion = 4 + 1 = 5

We are also told he has a total of 220 butterflies and moths.

Hence:

The number of butterflies he collects is calculated as

4/5 × 220 = 176 butterflies

The number of moth that he collects =

1/5 × 220 = 44 moth

You plan to borrow $36,500 at a 7.7% annual interest rate. The terms require you to amortize the loan with 7 equal end-of-year p

erma4kov [3.2K]

The amount of interest you would be paying in Year 2 is: $2,492.62.

<h3>Interest</h3>

First step is to calculate the Equal Monthly Payment

Equal Monthly Payment=P×r×(1+r)^t/(1+r)^t-1

Where:

P=Principal=$36,500

r=Rate=7.7%

t=Time=7 years

Equal Monthly Payment=36,500×0.077×(1+0.077)^7÷(1+0.077)^7-1

Equal Monthly Payment=36,500×0.077×(1.077)^7÷(1.077)^7-1

Equal Monthly Payment=36,500×0.077×1.6807763÷1.6807763-1

Equal Monthly Payment=4,723.82/0.6807763

Equal Monthly Payment=$6,938.875

Second step is to calculate Year 1 Closing balance

Year 1 Closing balance = Beginning balance + Interest - EMI Payment

Year 1 Closing balance= $36,500 +($36,500×7.7%) - $6,938.875

Year 1 Closing balance= $36,500 + $2,810.5 -$6,938.875

Year 1 Closing balance = $32,371.625

Third step is to calculate year 2 interest

Year 2 Interest= $32,371.625×7.7%

Year 2 Interest=$2,492.62

Therefore the amount of interest you would be paying in Year 2 is: $2,492.62.
