The sum of an equation is 45/100

One addend is 4/10
What is the missing addend?

The missing addend is 1/20

Step-by-step explanation:

Variable x: missing addend

4/10 + x = 45/100

When adding or subtracting fractions, the denominators must be the same number.

To convert 10 to 100, we must multiply 10 by 10.

If we multiply 10 to the denominator, we must do the same to the numerator (multiply by 10).

4 × 10 / 10 × 10

40/100

Use this fraction in the equation now

40/100 + x = 45/100

Now isolate the variable, x, by subtracting 40/100 from both sides

40/100 - 40/100 + x = 45/100 - 40/100

When subtracting fractions, only subtract the numerators. The denominators remain the same

x = 5/100

Simplify 5/100

Both numbers can be divided by 5

5 ÷ 5 / 100 ÷ 5

1/20

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

multiple all that
