Laura earns $2.90 more per hour than her friend, Jess. Write an equation to show how much Jess earns per hour. Use j to represent her hourly rate.How much does Jess earn if she works 20 hours
Answers
Answer:
Equations are
J=j → (1)
L=$2.90+J=$2.90+j → (2)
Jess earn $20j in 20 hours
Step-by-step explanation:
Given that Laura earns $2.90 more per hour than her friend, Jess.
we have to write an equation to show Jess earns per hour.
As j represents hourly rate of Jess i.e
Jess earns $j per hour.
∴ J=j → (1)
As Laura earns $2.90 more per hour than her friend, Jess
⇒ L=$2.90+J=$2.90+j → (2)
Eq (1) and (2) are required equation.
we have to find how much Jess earn in 20 hours
Hours=20
∴ In 1 hr Jess earn $j
In 20 hrs Jess earn $ 20j
"X" equals how much Laura Makes

Answer: y=-2x+12
Step-by-step explanation:
The slope goes down which makes it negative and the two yellow points make a line with a slope of =2. If you follow the line up, it would cross the y-intersection at 12. So the final line is y=-2x+12

Simplify √50.
Factor out 50.
√50 = √(5 x 5 x 2)
Note that there are 2 5's inside the parenthesis. Two of the same number when multiplied would become a whole number:
√(5 x 5) = 5
√50 = √(5 x 5 x 2) = 5√2
5√2 is your answer
~
The square root of a number is always going to be done like this. If 50 isn't a square root, what are the square root numbers multiplied by something else to make 50
25 is a square root because of 5 times 5 is 25
√25 x 2 = 50
Next carry out the 5 outside the square root and you would get
5√2 = √50
5√2 is your answer

Answer: Answer is x= 7 1/2
Step-by-step explanation:
This will be positive since there is no negative signs.
Answer:
x = 7 1/2
Step-by-step explanation:
12x = 90 Times both sides by 5
x = 90/12 Divide by 12 on both sides
x = 7 6/12 Find the closest multiplier
x = 7 1/2 Simplify

A regular polygon whose each interior angle equals 120° is called a Hexagon.
We know that if the interior angles of a polygon are equal, then the polygon is a regular polygon.
Also, by formula,
The sum of the interior angles of a regular polygon = (n - 2) × 180° where n = number of sides
And the interior angle of the polygon is given = 120°
So, the number of sides of the given regular polygon =
⇒ n = [(n - 2) × 180°] ÷ 120°
⇒ 120n = (n - 2) × 180°
⇒ 120n = 180n - 360°
⇒ 180n - 120n = 360°
⇒ 60n = 360°
⇒ n = 6
The number of sides of the regular polygon is 6 which means that the regular polygon is a Hexagon.
