12x + 4 divided by 4 plus 20x + 5 divided by 5

Mathematics
1 answer:
Rasek [7]2 years ago

12x + 4 ➗ 4 + 20x + 5 ➗ 5

1. PEMDAS (order of operations) solve the division problems

(4 divided by 4 & 5 divided by 5)
12x + 1 + 20x + 1

2. Swap around the order of operations as commutative property states that you can swap the order of an addition problem and get the same answer.

12x + 20x + 1 + 1

3. Add like terms

32x + 2

This is the most simplified answer you could get as you can not add 32x and 2 as they are not like terms.

What’s the inverse of y= 100 - x^2
Marianna [84]

Answer:

The inverse is ±sqrt(100-x)

Step-by-step explanation:

y= 100 - x^2

Exchange x and y

x = 100 -y^2

Solve for y

Subtract 100 from each side

x-100 = 100-100-y^2

x-100 = - y^2

Multiply by -1

-x+100 = y^2

100 -x = y^2

Take the square root of each side

±sqrt(100-x) = sqrt(y^2)

±sqrt(100-x) = y

The inverse is ±sqrt(100-x)

BRAINLIEST PLUS 38 POINTS
dlinn [17]

Answer:

8b is 220

Step-by-step explanation:

it might be 220 because we already know that from o to b is 140 degrees. We know that a full circle is 360, so take 140 away from 360, and you get 220.

360-140=220 degrees

Im not sure about the other questions but i hope this helps :)

frank has two same size rectangles divided into the same number of equal parts. one rectangle has 3/4 of the parts shaded, and t
nata0808 [166]

This question basically asks for the LCM of 3 and 5, which is 3 x 5 =15

This is the answer: 15

Check : The first rectangle had 1/3 shaded; ( one in every three parts)

So for 15 parts  altogether, 5 would be shaded ( 1/3 = 5/15)

The second rectangle had 2/5 shaded ( two for every five parts)

So for 15 parts altogether, 6 would be shaded (2/5 = 6/15)
