Because you can simplify 40/100 and get 4/10
when you divide 40/100 by ten on the den. and num. you will get 4/10
Answer:
-4 and 8
Step-by-step explanation:
When looking at the number line to get the opposite of a number take your number and count that many numbers on the opposite side of the 0 (zero).
So if your number is -4 count that many on the opposite side of the zero to get 4.
Answer:
65°
Step-by-step explanation:
The sum of the angles of a triangle is always 180°. Meaning, ∠P + ∠Q + ∠R = 180.
(2x-9) + (2x+4) + x = 180
Combine like terms:
5x-5 = 180
5x = 185
x = 37
P = (2x - 9) = 2(37) - 9 = 74 - 9 = 65
Overall dimensions of the page in order to maximize the printing area is page should be 11 inches wide and 10 inches long .
<u>Step-by-step explanation:</u>
We have , A page should have perimeter of 42 inches. The printing area within the page would be determined by top and bottom margins of 1 inch from each side, and the left and right margins of 1.5 inches from each side. let's assume width of the page be x inches and its length be y inches So,
Perimeter = 42 inches
⇒ 
width of printed area = x-3 & length of printed area = y-2:
area = 
Let's find 
:
= 
, for area to be maximum = 0
⇒ 
And ,
∴ Overall dimensions of the page in order to maximize the printing area is page should be 11 inches wide and 10 inches long .
6x + 8 = 50
Our goal is to get the variable x on its own.
We can start by subtracting 8 from each side. (subtraction prop. of eq. lets us do this)
6x + 8 - 8 = 50 - 8
6x = 42
Now, we must divide each side by 6 to find the value of x.
6x ÷ 6 = 42 ÷ 6
x = 7
