Sam had $25 more than Mary, and together they had enough money to buy a video game for $57 and to pay $16 for two movie tickets. How much money did Mary have?
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
In a Physics lesson, Chantelle adds weights to a spring and carefully measures the extension. She finds that the weight, y g is related to the extension, x cm by the formula y = 0.5x + 1 for 0 ≤ x ≤ 20. a Draw the graph of y against x for 0 ≤ x ≤ 20. b Use this graph to find the (i) weight for a 17 cm extension (ii) extension produced by a 5 g weight. c What would Chantelle's formula predict for the springs extension for a 1 kg weight?

Answer:
- 14
Step-by-step explanation:
4x + 6 = - 62
4x = - 62 + 6
4x = - 56
x = - 56 / 4
x = - 14
The value of x in this equation will be; x = -14
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given that the equation 4x + 6 = - 62
Here, we need to solve for x
4x + 6 = - 62
4x = - 62 + 6
4x = - 56

used
a. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal
b. What will the value of each card be when they have equal value?
Answer:
37
Step-by-step explanation:
It will take twenty 30-day periods until the value of the gift cards will be equal. The value of each card when they have equal value is $10
What is an expression?
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Let x represent the number of 30-day periods until the value of the gift cards will be equal.
Tavon has a gift card for $90 that loses $4 for each 30-day period it is not used. This means that x 30-day periods, the amount left would be
90 - 4x
He has another gift card for $ 80 that loses $3.50 for each 30-day period it is not used. This means that x 30-day periods, the amount left would be
80 - 3.5x
For the amounts left on each card to be the same, the number of periods would be
90 - 4x = 80 - 3.5x
90 - 80 = - 3.5x + 4x
10 = 0.5x
x = 10/0.5
x = 20
The value of each card when they have equal value is
90 - 4 × 20 = 90 - 80
= $10
Therefore, It will take twenty 30-day periods until the value of the gift cards will be equal. The value of each card when they have equal value is $10

The waves will cover a circular area of 7542.96 miles.
What is the area of the circle?The circle is defined as the locus of the point traces around a fixed point called the center and is equidistant from the outer trace. The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
Given that a radio station sends out radio waves in all directions from a tower at the center of the circle of broadcast range. The circle has a diameter of 98 miles.

Graph the image of the given triangle after a rotation of 180° about the origin
Answer:
The bottom point is at (-1, 1) the right point is at (6,-2) and the left point is at (-5,4)
Step-by-step explanation:
Rotation of any polygon about the origin gives the opposite sign coordinate of the original figure thus new coordinate will be (1,-1),(2,-6), and (5,-4).
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If a coordinate of any polygon (x,y) is rotated 180 degrees about the origin either clockwise or anticlockwise then its coordinate will change sign.
(x,y) → (-x,-y)
Given triangle have coordinates as (-1,1),(-2,6), and (-5,4).
The transformation (x,y) → (-x,-y) gives ;
(-1,1) → (1,-1)
(-2,6) → (2,-6)
(-5,4) → (5,-4)
Hence "Rotation of any polygon about the origin gives the opposite sign coordinate of the original figure thus new coordinate will be (1,-1),(2,-6), and (5,-4)".

Answer:
The graph of y = a·f(x) will compress (or shrink) vertically when |a| < 1.
Step-by-step explanation:
A compression is a transformation that decreases the distance between corresponding points of a graph and a line.
A vertical compression (or shrink) by a factor of a , such that y = a·f(x), where 0 < a < 1. This means that when a is between 0 and 1, the parent graph tends to widen.
In the given problem where y = 0.1x², the a = 0.1, which made the graph wider. This represents the vertical shrink (toward the x-axis) by a factor of 0.1.

What is the slope of a line perpendicular to the line whose equation is 10x + 6у –84. Fully simplify your answer.
Answer:
The slope is 3/5.
Step-by-step explanation:
I am assuming you mean
10x + 6y = 84
6y = -10x + 84
y = -5/3 x + 14.
So the slope of this line is -5/3 and the slope of a line perpendicular to it is
-1 / -5/3 = 3/5.
