We need to set the 1st number as x. Since the integers are consecutive we just add 1 more for each integer, so the 2nd number is x + 1, then x + 2, x + 3, and x + 4. When we add them all together we get 130 so...

x+(x+1)+(x+2)+(x+3)+(x+4)= 130

Since it is only addition we don't have to keep the parentheses because of the associative property.

x+x+1+x+2+x+3+x+4=130
5x + 10 = 130
5x = 120
x = 24

So the first number is 24.
2nd number is x+1 or 25. 3rd number is x+2 or 26 and so on...

Your consecutive numbers are 24, 25, 26, 27, and 28.

We can check by adding them up and see if they equal 130.

24+25+26+27+28= 130

It checks!

Translate the verbal statements into a system of linear equations: Fatima invested a total of $1000 in two simple-interest bank

Answer:

Step-by-step explanation:

Translate the verbal statements into a system of linear equations: Fatima invested a total of $1000 in two simple-interest bank accounts. One account paid 5% annual interest; the other paid 6% annual interest. The total amount of interest she earned after 1 year was $56

Simple interest formula =

I = PRT

We are to find the Amount = Principal invested

For Account 1

I1 = P × 5% × 1

= 0.05P

Account 2

I2 = P × 6% × 1

= 0.06P

Therefore:

0.05P + 0.06P = $56

The polynomial 2x3 − 5x2 + 4x − 10 is split into two groups, 2x3 + 4x and −5x2 − 10. The GCFs of each group is then factored out

Ugo [173]

$Answer: \\ 2 {x}^{3} - 5 {x}^{2} + 4x - 10 \\ = (2 {x}^{3} + 4x) - (5 {x}^{2} + 10) \\ = 2x( {x}^{2} + 2) - 5( {x}^{2} + 2) \\ = ( {x}^{2} + 2)(2x - 5) \\ Common \: binomial \: factor:2x - 5$
