3. First, turn the fractions into improper fractions
11/8 + 11/4
Since we can't divide 11 by 2 to make the denominator of the first fraction 2, let's multiply both sides of the second fraction by 2 instead.
11/8 + 11*2/4*2 = 11/8 + 22/8
<u>33/8, or 4 1/8</u>
(I already answered numbers 4 and 6 in a previous question you asked)
5. 1 1/2 + 2 3/4
Obviously, we'll start by converting the fraction into improper fractions.
3/2 + 11/4
Multiply both sides of the first fraction by 2
3*2/2*2 + 11/4 = 6/4 + 11/4 = 17/4
<u>17/4, or 4 1/4</u>
Answer: 25 and 33
Step-by-step explanation:
17+8= 25
25+8= 33
33+8= 41

Explanation:
Given function: f(x) = -2x² - 3x + 20
To find the x-intercepts of a function, f(x) = 0
=================
-2x² - 3x + 20 = f(x)
-2x² - 3x + 20 = 0
-2x² - 8x + 5x + 20 = 0
-2x(x + 4) + 5(x + 4) = 0
(-2x + 5) (x + 4) = 0
-2x + 5 = 0, x + 4 = 0
-2x = -5, x = -4
x = -5/-2,x = -4
x = 5/2, x= -4
Coordinates: (-4, 0), (5/2, 0)
Answer:
Given: TN=22.4 inches
So MP is half that amount
22.4/2= 11.2
Step-by-step explanation:
That blank is a plus sign
ok so rememmber you can do anythiing to an equation as long as you do it to both sides
-0.3x+2=0.4x-0.1
add 0.3x to both sides
2=0.7x-0.1
add 0.1 to both sides
2.1=0.7x
times 7 both sides
21=7x
divide both sides by 7
3=x
