Answer:
11.50
Step-by-step explanation:
The new wage is equal to the old wage plus her raise, so:
x + 0.75 = 12.25
or
x= 12.25-0.75
Meaning x is her original wage, being $11.50

g(x) = 4x -9, what is g^-1(x)
Answer:
g^-1(x)= 1/4x-9
1 is above 4x-9
Step-by-step explanation:
g(x)= 4x-9
and g^-1 = 1/g(x)
so:
1/gx=1/4x-9
What is the value of y? O A. 10° O B. 55 O C. 110° O D. 85°
Answer:
55
Step-by-step explanation:
40+y+30+y=180
40+2y+30=180
70+2y=180
2y=110
y=55
Checking: 55+40+(55+30) = 55+40+55+30 = 180

The perimeter of a rectangle is 42 cm. The length is 3 cm greater than the width. Find the width and length
Answer:
width:9
length: 12
Step-by-step explanation:
width: substitute for x
length: since the length is 3 cm greater than the width, we substitute it for x+3.
we know that you need to add all the lengths to find the perimeter, and we know that the perimeter of the rectangle is 42 cm, so our equation is formed.
x+x+x+3+x+3=42
4x+6=42
4x=36
x=9
width:9
length:9+3=12
Carla traveled 320 miles in 5 hours. At this rate, how far will Carla travel in 7 hours?
Answer:
448 miles
Step-by-step explanation:
If 5 hours = 320 miles
then 7 hours = ?
7 hours will give more so if more less divide
7hours ÷5hours × 320 miles
hours will cancel out
= 7÷5×320 miles
= 448 miles
Hence,Carla will travel 448 miles in 7 hours
Manuel wants to go snowboarding with his friends. The closest ski and snowboard resort is approximately 20 miles west and 50 miles north from his house. Manuel picks up his friend who lives 15 miles south and 10 miles east of Manuel's house. How far are the two boys from the resort
Answer:
Step-by-step explanation:
First we need to calculate the displacement of the resort from Manuel's house using Pythagoras theorem.
S1 = √50²+20²
S1 = √2500+400
S1 = √2900
S1 = 53.85m
Next is to calculate the displacement of Manuel's friend house to Manuel's house.
S2 = √15²+10²
S2 = √225+100
S2 = √325
S2 = 18.03m
The displacement of the two boys from the resort will be ∆S = S2-S1
∆S = 53.84-18.03
∆S = 35.81m

At a sale, dresses were sold for $144 each. If the dresses originally cost $200, what percentage of its original price was a dress sold for?
Answer:
72%
80% of 200 is 160.
75% of 200 is 150.
74% of 200 is 148.
72% of 200 is 144
Just to make sure ask google or siri "What is 72% of 200?".
Hope this helps!
Answer:
28% (because it was marked down by $56 dollars)
Step-by-step explanation:
144/200 = 72%
100% (200) - 72% (144) = 28% (56)
56/200 = 28%
28% (56) + 72% (144) = 100% (200)

The two angles must be supplementary and adjacent to form a linear pair.
Any two adjacent angles form a linear pair.
Any two adjacent angles form a linear pair.
Any two supplementary angles are a linear pair.
Any two supplementary angles are a linear pair.
Vertical angles can form a linear pair.
Answer:
2
Step-by-step explanation:
;\
Answer: Choice A
The two angles must be supplementary and adjacent to form a linear pair.
Adjacent angles are angles that touch and share a common line segment, line, or ray. Think of two rooms that share the same wall and how they are considered adjacent rooms.
Supplementary angles form a straight angle. They add to 180 degrees.

Greatest to least 1/2 0.12 2/3 0.6
Answer:
2/3, 0.6, 1/2, 0.12
Step-by-step explanation:
1/2, 0.12, 2/3, 0.6
im going to switch each to decimal if it isn't already
1/2 = 0.5
2/3 = 0.666 repeated
so now we have
0.5 , 0.12, 0.666 repeated, 0.6
now im going to put them in order
0.666 repeated, 0.6, 0.5, 0.12
now im going to change them back
2/3, 0.6, 1/2, 0.12
Answer: 2/3, 0.6, 1/2, 0.12
Step-by-step explanation:
First I'm going to convert the fractions to decimals:
1/2 = 0.5 and 2/3 = 0.7 (rounded). Now the problem looks like: 0.5, 0.7, 0.12, 0.6. Organizing from greatest to least: 0.7, 0.6, 0.5, 0.12
