Determine whether the ordered pair (-5,36) is a solution to the equation 2x- y/2 = -8

Answers

Answer 1
No.
An order pair is in the format of (x,y). Therefore, in the order pair (2,4), 2 is the x and 4 is the y. When you plug these numbers into the equations you don’t get equal answers:

4(2) = 4 - (4)
8 ≠ 0

3(2) = 26 + 5(4)
6 ≠ 46

Answers

Answer:

n = 5.75

Step-by-step explanation:

4(5.75) - 18 = 5

4(5.75) = 23

23 - 18 = 5

Therefore, n = 5.75.

Hope this helps:)

I would appreciate it if you gave me brainliest. Thanks.

The answer
Is 5.75
That’s because 18+5=23 and 23 divided by 4 equals 5.75 and to make sure. 5.75*4=23 23-18=5.

3 equivalent fractions for 2/3 are:

•4/6 (multiply the numerator and denominator by 2)
•6/9 (multiply the numerator and denominator by 3)
•8/12 (multiply the numerator and denominator by 4)

Basically all you have to do is multiply the numerator and denominator by any number as long as you keep it the same.

Hope you have a wonderful day ;)

Answer:

2/3

Step-by-step explanation:

Answer:

40cm

Step-by-step explanation:

If you are converting 40cm to one inch and the conversion ratio is 2.54 : 1, you would place 40 in the numerator as the original ration has 2.54/1 as a fraction and the same will apply to 40cm.

** This applies if you are finding which number is in the numerator and not the answer to how much 40cm in inches is.

0 3 x 10°
30 x 108
0 30 x 10

Answers

Answer:

3 x 10^8

Step-by-step explanation:

300,000,000 in scientific notation is 3 x 10^8 and because it’s 8 zeros

The number 300,000,000 represented in scientific notation will be 3 × 10⁸. Then the correct option is A.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

What slope is perpendicular to:
m = 5/8

Answers

the perpendicular slope would be m=-8/5

The slope that is perpendicular to m = 5/8 is given by; m' = -8/5

When dealing with slope - intercept form of equation of a line, the general equation is;

         y = mx + c

where;

m is the slope

c is the y-intercept

Now, for a line to be perpendicular to a line above that has it's slope as m, the slope of this new line will be the negative inverse of the first slope. This is;  m' = -1/m

Applying that to our question, it means the slope that is perpendicular to m = 5/8 is; m' = -1/(5/8) = -8/5
