Answer:
25 and29
Step-by-step explanation:
let x be one number
then according to questions another number will be x+4
we can write
x+x+4=54
2x=54_4
2x=50
x=50/2
x=25
one number is 25 and another number is 25+4=29

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

70+2y=180
2y=110
y=55
Checking: 55+40+(55+30) = 55+40+55+30 = 180
Which of the following is true about a linear pair?
The two angles must be supplementary and adjacent to form a linear pair.
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.

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)

Your class is going on a field trip to the Miami Science Museum.
It costs $20 for each adult (a) and $13 for each student (s).
Write an expression for the cost of adults and students to enter
the museum. Then, find the total cost for 4 adults and 24
students.
Answer:
Total is 392
Step-by-step explanation:
$20 - Adult (x)
$13 - Student (y)
20(x) + 13(y) = Total
20(4) + 13(24) =
80 + 312 = 392

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

Step-by-step explanation:
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

The steps to convert 18 over 8 to a decimal are shown below: Division is shown with divisor 8 and quotient 2.35 and dividend 18. The numbers below 18 in sequence are subtract 16 labeled as Step 1, 20, subtract 16 labeled as Step 2, 40 labeled as Step 3, subtract 40, and 0 labeled as Step 4. In what step is the first error?
Answer:
Step 2
18 over 8 to a decimal is 2.25
Step-by-step explanation:
Step 1, 20, subtract 16 labeled as
Step 2, 40 labeled as
Step 3, subtract 40, and 0 labeled as Step 4.
Divisor = 8
Divided = 18
Quotient = 2.25
2.25
8 √18

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
