Answer:

-15a² -14a+16

Step-by-step explanation:

<h2>(2-3a)(8+5a)</h2>

2×8=16

2×5a=10a

-3a×8=-24a

-3a×5a=-15a²

16+10a-24a-15a² = -15a² -14a+16

In the following answer, why does 830 convert to 83000?
Mekhanik [1.2K]

Then the money borrowed insurance company is $1,000.

Money borrowed from insurance company = $1000

Let the money borrowed by her friend at 8% interest = x

Then the money borrowed by the bank at 9% interest = 2x

<h3>What is the total money?</h3>

Total money borrowed = $10,000

So, the money borrowed from the insurance company = 10,000-(2x+x)

= 10,000-3x

Total interest for the first year = $830

We have the equation,

8%(x) + 9%(2x) +5% (10,000-3x) = 830

8x+18x+50,000-15x = 83,000

11x = 83000-50000

11x = 33,000

x = $3000

Then the money borrowed insurance company = 10,000-3x

Then the money borrowed insurance company is $1,000.

Makovka662 [10]

Answer:

<h2>x = 4</h2>

Step-by-step explanation:

-7x-3x=-8x-8\\\\-10x=-8x-8\qquad\text{add}\ 8x\ \text{to both sides}\\\\-10x+8x=-8x+8x-8\\\\-2x=-8\qquad\text{divide both sides by (-2)}\\\\\dfrac{-2x}{-2}=\dfrac{-8}{-2}\\\\x=4

Find 2 sum whose sum is 4806 and difference is 1050 explanation​
arlik [135]

Answer:

The two numbers are 2928 and 1878

Step-by-step explanation:

Given this information, we can set up two equations:

x + y = 4806

x - y = 1050

We can solve these simultaneous equations by elimination, which means we can either add or subtract the two equations to solve one of the variables.

In this case, adding the equations together will eliminate y so we can solve for x (remember that y + - y is the same as y - y):

   x + y = 4806

+  x - y = 1050

____________

   2x     = 5856

This can then be simplified to x = 2928 (by dividing by 2)

Now we know x, we can substitute this value into any equation to find y:

2928 + y = 4806 so y = 4806 - 2928 which is 1878.

The two numbers are 2928 and 1878.

Hope this helps!
