Answer:
x= -10
Step-by-step explanation:
-8x+10x+20=0
2x+20=0
2x=0-20
2x=-20
x=-20/2
x= -10
Answer:
x = -10
Step-by-step explanation:
8x (-10x)= 10x +20 (-10x)
subtract 10x from both sides of the equation
-2x/-2 = 20/-2
divide both sides by -2
x = -10

A journalist is assigned to write a story that is 1,200 words long. To fit in the publications available space, the story's length can vary by no more than 75 words.
which word counts would be accepted by the journalist's publication?
1,100 1,125 1,290 1,260 1,300
The word count that can be accepted by the journalist's publication is 1,260.
Given,
A journalist is assigned to write a story that is 1,200 words long.
To fit in the publication's available space, the story's length can vary by no more than 75 words.
We need to find which word counts would be accepted by the journalist's publication.
1,100, 1,125, 1,290, 1,260, 1,300
Find the number of words the publication accepts.
We have,
1,200 words long.
The story's length can vary by no more than 75 words.
So,
1,200 + 75 = 1,275 words
The words can vary from 1,200 to 1,275 words.
Find the option which can be accepted.
1,100 - can not be accepted
1,125 - can not be accepted
1,290 - can not be accepted
1,260 - can be accepted
1,300 - can not be accepted
Thus the word count that can be accepted by the journalist's publication is 1,260.

A weather balloon is launched in Texas from an altitude of 240 feet above sea level. If the balloon rises at a constant rate of 65 feet per
minute, which of the following equations could be used to find t, the time in minutes it will take the balloon to reach an altitude of 11,000
feet?
O A. 11,000 = 240t + 65

-11x - 7y = -56, solve for y (must be in form y = mx + b)
Answer:
y= -11/7x+8
move variables to the right hand side and change its sign
-7y=-56+11x
change the signs on both sides of the equation
7y=56-11x
divide both sides by 7
y=8-11/7 x
reorder the terms and get y= -11/7x+8

Step-by-step explanation:
Monarch butterflies migrate from Canada to Mexico every fall. It is estimated that the butterfly travels about 82 km each day. Suppose the butterfly travels from Edmonton to El Rosario. This is a distance of about 3936 km. How many days does it take? How did you decide which operation to use?
Given:
Butterfly can travels = 82 km each day.
Total distance = 3936 km.
To find:
The number of day it takes to travel the given distance.
Solution:
Let the number of days it takes to travel be d.
Butterfly can travels about 82 km each day.
So, distance traveled by it in d days = (82d) km
Total distance is about 3936 km.
[tex]82d=3936[/tex]
To isolate d , we need to divide both sides by 82.
[tex]\dfrac{82d}{82}=\dfrac{3936}{82}[/tex]
[tex]d=48[/tex]
Therefore, the required number of days is 48.

1). [tex]8\frac{1}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]
= [tex]\frac{33}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]
= [tex]\frac{33}{4}\times \frac{4}{3}[/tex]
= 11
2). [tex]3\frac{1}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]
= [tex]\frac{10}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]

= 1
3). [tex]\frac{5}{4}[/tex] ÷ [tex]\frac{1}{4}[/tex]
= [tex]\frac{5}{4}\times \frac{4}{1}[/tex]

= 1
5). [tex]11\frac{1}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]
