Reuben has 26 new magazines to read.
Let M be the number of magazines he would have left to read after reading R of them.
Write an equation relating M to R. Then use this equation to find the number of magazines he would have left to read after reading 21 of them.
Equation:
Nomber left to read after reading 21 of them: magazines

Answers

Answer 1

Answer:

5

Step-by-step explanation:

So the total number of magazines he has to read are 26

He has read R magazines = 21 magazines

So the equation relating M to R is

m + r = 26

We also know that r = 21

Hence, m + 21 = 26

subtract 21 from both sides

m = 5

Answer 2

The equation is m + r = 26

And, the number of magazines should be 5

Calculation of the number of magazines:

Since Reuben has 26 new magazines to read

And, here  M be the number of magazines he would have left to read after reading R

So here the equation is m + r = 26

Since r = 21

So, m + 21= 26

m = 5

1. Factor x²+5x-24
2. Factor 2n²-5n-3

Answers

Given problems;

 1. Factor;  x²+5x-24

To factor this equation, we must understand that this is a quadratic equation.

A quadratic equation usually has two roots.

Equate to zero;

            x²+5x-24 = 0

Then find two numbers whose product is -24 and their sum is +5

  the numbers are  +8 and -3

 then replace 5x with the number;

        x² + 8x - 3x - 24  = 0

Now factorize;

     x(x +8) - 3(x + 8) = 0

        (x-3)(x+8)  = 0

Factoring gives (x-3)(x+8)

2. Factor 2n² - 5n -3;

Equate to zero;

   2n² - 5n -3 = 0

Find the number whose sum is -5 and the product gives -6( 2 x -3);

      the number is -6 and +1;

   2n² - 6n + n -3 = 0

   2n(n-3) + 1(n-3) = 0

     (2n + 1)(n-3) = 0

The factor of the equation is (2n + 1)(n-3).

Answers

Answer:

(-1,-1)

Step-by-step explanation:

The easiest way I know how to explain it is you put the numbers on a line for instance

-6, -5,-4,-3,-2,-1,0,1,2,3,4

and the number in the very middle of the y then for x

-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9

and then again you use the midpoint for the x

because they are trying to meet each other half way you are trying to find the midpoint.

1) The product of a number and -7 is 63

2) 10 subtracted from a number is 15

3) two-fifths of a number is -12

4) 8% of a number is 20

5) the sum of twice a number and 17 is -1

6) nine less than the product of a number and -4 is 35

Answers

Step-by-step explanation:

let the no. be x

for 1,

x× -7 = 63

or, x= 63 ÷ -7

or, x = -9

therefore -9times -7 is 63.

for 2

by question

x -10= 15

or, x = 15+10

or, x = 25

therefore 25 minus 10 equals 15.

for 3

by question

(2/5) of x = -12

or, x = -12×(5/2)

r, x= -6×5

or, x = -30

therefore 2/5 of -30 is -12

for 4

by question,

8%of x = 20

or, 8x/100=20

or, 8x = 20×100

or, x = 2000÷8

or, x= 250

therefore 8% of 250 is 20.

for 5

by question,

2x+17 = -1

or, 2x = -1 -17

or, 2x = -18

or, x = -18 ÷ 2

or, x =-9

therefore -9 times 2 plus 17 equals -1.
