Answer:
Mary had $24
Step-by-step explanation:
So to solve this question, we first have to create an equation.
Mary's money=x
Since Sam had $25 more than Mary, $Sam+$Mary is (25+x)+x.
With this money, they can buy something worth $57 and something worth $16, so that means (25+x)+x=57+16
Now we solve the equation-->
(25+x)+x=57+16
Combine x and x to get 2x.
25+2x=57+16
Add 57 and 16 to get 73.
25+2x=73
Subtract 25 from both sides.
2x=73−25
Subtract 25 from 73 to get 48.
2x=48
Divide both sides by 2.
x= 2/48
Divide 48 by 2 to get 24.
x=24

The points H, I, J and K all lie on the same line segment, in that order, such that the
ratio of HI:IJ: JK is equal to 3: 3:4. If HK - 40, find IJ.
Answer:
IJ = 12
Step-by-step explanation:
sum the parts of the ratios, 3 + 3 + 4 = 10 parts
Divide HK by 10 to find the value of one part of the ratio.
40 ÷ 10 = 4 ← value of 1 part of ratio , then
IJ = 3 parts = 3 × 4 = 12

In the diagram, line l is parallel to line m and is cut by transversal n. The measure of angle one is equal to 3x+6 and angle two measures 6(x−2).
What is the measure of angle one?
Answer:
24
Step-by-step explanation:
Since the lines L and M are parallel:
Angle 1 and and 2 are alternate and their measurement is equal.
3x + 6 = 6x - 12 (we multiplied 6 with inside the parenthesis)
6 + 12 = 6x - 3x
18 = 3x divide both sides by 3
6 = x to find the angle measure replace x with 6
3x + 6 is 3*6 + 6 = 24

How can 7 1/5+-8 3/5 be expressed as the number of its integer and fractional parts?
A) -7+ -8+-1/5+-3/5
B) 7+ -8+1/5+-3/5
C) 7+ -8+1/5+3/5
D) -7+ -8+1/5+3/5
Answer:
-7/5
Step-by-step explanation:
7×5=35
35+1=36
7 1/5 = 36/5
8×5=40
40+3=43
8 3/5 = 43/5

5x+3y=-16
-10x-3y=11
Find the solution
Answer: x = 3.2 + 0.6y
Step-by-step explanation: Simplifying
5x + -3y = 16
Solving
5x + -3y = 16
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
5x + -3y + 3y = 16 + 3y
Combine like terms: -3y + 3y = 0
5x + 0 = 16 + 3y
5x = 16 + 3y
Divide each side by '5'.
x = 3.2 + 0.6y
Simplifying
x = 3.2 + 0.6y
You and a friend are discussing how many sections you completed so far in algebra one you tell your friend I finish three times as many sections as you your friend replies you’ve only finished four more sections and I have how many sections have you and your friend completed
Answer:
4
Step-by-step explanation:
There are a total of 6 sections that have been completed by him and his friend.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Let the section be finished by one is y, and finished by his friend be x.
According to 1st condition,
y = 3x - - - - - (1)
According to the second condition,
y = 4 + x
From equation 1
3x = 4 + x
2x = 4
x = 2
Now,
y = 3x
y = 3 * 2
y = 6
Thus, there are a total of 6 sections that have been completed by him and his friend.

The length of the subway is 113 miles. if 4.1 inches represents 677 miles, what is the length of the subway on the map? Round your answer to the nearest
hundredth if needed.
Answer:
0.68 inches (nearest hundredth)
Step-by-step explanation:
First, find the length on the map that represents 1 mile of the subway.
677 miles ----- 4.1 inches
1 mile ----- 4.1 ÷ 677= 0.0060561 inches (5 s.f.)
Multiply both sides by 113:
113 miles ----- 113(0.0060561)= 0.68 inches (nearest hundredth)
Thus, the length of the subway on the map is 0.68 inches.

What is the completely factored form of this polynomial?
18x3 – 120x2 - 42x
Write the greatest common factor (GCF) first, and write all factors in standard form.
Answer:
6x(3x + 1)(x - 7)
Step-by-step explanation:
First look for the greatest common factor of the 3 terms.
The GCF is 6x, so
18x^3 – 120x^2 – 42x
= 6x(3x^2 - 20x - 7)
Now we look to factor the quadratic expression in the parentheses:
The first and last coefficients are multiplied
3 * -7 = -21.
We look for 2 numbers whose product is -21 and whose sum is -20:
They are -21 and + 1 , so we write:
6x(3x^2 - 21x + 1x - 7)
= 6x [ (3x(x - 7) + 1(x - 7)] Note that x - 7 is common, so:
= 6x(3x + 1)(x - 7) Answer

Determine the intercepts of the line. Do not round your answers. 2 x + 5 y = − 6
The y-intercept for the line, 2x + 5y = -6, is: 1.2.
Equation of a Line in Slope-Intercept FormThe equation of a line can be represented in slope-intercept form as: y = mx + b."b" is the y-intercept.Given:
2x + 5y = -6
Rewrite in slope-intercept form
5y = -2x - 6
Divide both sides by 5y = -2/5x - 6/5
"b" = -6/5 = 1.2
Therefore, the y-intercept for the line, 2x + 5y = -6, is: 1.2.
