5a+5b=25 and -5a+5b=35

Mathematics
1 answer:
Alex_Xolod [135]3 years ago
3 0

add the two equations together

5a+5b=25

-5a+5b=35

------------------

 0  + 10b =60

divide by 10

b=6

5a + 5b = 25

5a +5(6) = 25

5a +30 =25

subtract 30 from each side

5a =-5

divide by 5

a = -1

Answer (-1,6)

or a=-1 b=6

Answer:

<u>29/48</u>

Step-by-step explanation:

3 5/8  Divided By 6= 29/48

Dividing fractions is simple if you know what to do, and how to multiply.

Here's how:

-----------------------------

<u><em>1. convert any whole number or mixed number into a fraction.</em></u>

<em>6 = 6/1.</em>

Whole number <u><em>x</em></u> denominator <u><em>+ </em></u>numerator = <em><u>29/8</u></em>

 (3)                              (8)                       (5)         (answer/original denominator)

-----------------------------

<u><em>2. Keep, Change, Flip (KCF)</em></u>

29             1

__      x     __

8                6

With KCF, we keep the first fraction, change the division to multiplication, and flip the second fraction.

---------------------------------------

<em><u>3. Multiply numerators and denominators</u></em>

29 x 1 =      29

                  __

8 x 6   =     48

29/48 is in it's simplest form.

Hence, your answer.

Klio2033 [76]

Explanation:

We can find the slope by solving for y.

  3x +2y +7 = 5x +3y +10

  -2x -3 = y . . . . . . . . . . . . . add -5x-10-2y to both sides of the equation

In this form, the slope (m) is the coefficient of x, -2. Hence m = -2.

__

<em>Alternate solution</em>

A graph of the equation shows it has an x-intercept of -1.5 and a y-intercept of -3. The slope (m) is then "rise" divided by "run", or ...

  m = rise/run = -3/1.5

  m = -2
