In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1. For example, if 50km is covered in 5.5 hours, the unit rate will be 50km/5.5 hours = 9.09 km/hour.

True or False: In order to solve an equation, we must isolate the variable.
Please help I'll give the brainiest to the right answer!
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
Because vertical angles are always equal, we want to solve [tex]50x+10=70x-10[/tex].
We can add 10 to both sides to get [tex]50x+20=70x[/tex].
We can subtract [tex]50x[/tex] from both sides to get [tex]20=20x[/tex].
Lastly, we divide both sides by 20 to get [tex]1=x[/tex].
So, [tex]\boxed{x=1}[/tex] and we're done!
The check is left as an exercise to the reader.
Answer:
x= 1
Step-by-step explanation:
TO solve you can use the equation 50x+10=70x-10.
First, subtract 10 from both sides:
50x= 70x-20
Then subtract 70x from both sides:
-20x=-20
Then divide by -20:
x=1
Check your work:
50(1)+10=70(1)-10
50+10=70-10
60=60

Write a real life scenario that could model the following relationship:
y=20x+60
Make sure to include what x and y represent in your description.
Answer:
You work for x hours and earn $20 for each hour. You get paid $60 before you come in each day. What is y when you work for x hours?
Step-by-step explanation:
x is the independent variable and can vary. You have to add the $60 in there, too. Adding them together gets you to y = 20x + 60 and this real life scenario works.

Find the perimeter of triangle ABC
Answer:
20 units
Step-by-step explanation:
to solve this equation you need the pythagorean theorem: a^2 + b^2 = c^2
2^2 + 7^2 = 53; square root of 53 is 7.28010989; or about 7.3 units (line AC)
2^2 + 6^2 = 40; square root of 40 is 6.32455532; or about 6.3 units (line BC)
4^2 + 5^2 = 41; square root of 41 is 6.40312424; or about 6.4 units (line AB)
7.3 + 6.3 + 6.4 = 20

Figure B is a scaled copy of Figure A
What is the scale factor from Figure A to Figure B?
Answer:
[tex]1/2[/tex]
Step-by-step explanation:
Because they are scaled copies, the ratios of the sides are equal.
Figure A has a base of 6 units by inspection.
Figure B has a base 3 units by inspection.
So, the scale factor from Figure A to Figure B is [tex]3/6=\boxed{1/2}[/tex] and we're done!
The scale factor from Figure A to Figure B is 1/2
What is the scale factor from Figure A to Figure B?Figure A:
Base = 6 units
Height = 4 units
Figure B:
Base = 3 units
Heights = 2 units
Using Base of the shape:
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape
= 3 units / 6 units
= 1/2
Using Height of the shape:
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape
= 2 units / 4 units
= 1/2
Hence, 1/2 is the scale factor from Figure A to Figure B.
