Jori has 7 boxes of books,with each box holding the same number of books.he has126 books in all how many books are there per box

bazaltina [42]

Let b be the number of books in a box. Then we can say that the total number of books is equal to the number of boxes times the number of books per box.

7b=126 divide both sides by 7

b=18

So there are 18 books per box.

Find four consecutive even integers so that the sum of the first three is 2 more than twice the fourth

scoundrel [369]

Answer:

The numbers are : -20,-18,-16,-14

Step-by-step explanation:

Let 1st even integer be $=x$

So, next consecutive even integer would be $=x+2$

3rd consecutive even integer would be $=x+4$

4th consecutive even integer would be $=x+6$

Sum of first three integers would be $=x+x+2+x+4=3x+6$

It says sum of the first three is 2 more than twice the fourth,

So we have

$3x+6=2+4(x+6)$

using distribution to simplify.

$3x+6=2+(4\times x)+(4\times6)$

$3x+6=2+4x+24$

$3x+6=4x+26$

Subtracting $4x$ from both sides

$3x+6-4x=4x+26-4x$

$-x+6=26$

Subtracting 6 from both sides

$-x+6-6=26-6$

$-x=20$

∴ $x=-20$

So first integer =-20

2nd integer $=-20+2=-18$

3rd integer $=-18+2=-16$

4th integer $=-16+2=-14$

So, the numbers are : -20,-18,-16,-14

Ali currently has $25. He is going to start saving $5 every week. Ali's Savings Function Rule: y = 5x + 25

Alenkasestr [34]

The rate of change of any given function is simply taken to be the 1st derivate of that function.We are given:y = 5 x + 25So the rate of change is simply, rate of change = dy / dxdy = 5 dxdy / dx = 5
So rate of change = 5
