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

Answer:
7, 7 1/8, 7 3/8, 7 5/8, 7 3/4, 8, 8 1/4, 8 1/2, 8 7/8
Step-by-step explain:
7 is the smallest number in the given numbers. 7 1/8 is the second smallest because 1/8 is smaller than 1/4. You can also think of it like you have a pizza/pie/cake and 1/8 of that cake is 1 piece of the cake that has 8 pieces in total. 1/4 on the other hand is a bigger piece. You can use this information to figure out future problems. 1/4 is the same as 2/8. In other words, 1/4 is equal to 2 slices of pie/cake/pizza/whatever you want it to be because if you take a cake, cut it into 4 pieces, then cut the 4 pieces in half. You will get 8 pieces.

Which of those points does not lie on the line y = 3x + 5*
(1 Point)
O (1,8)
O (4, 17)
O (-2, 11)
0 (0,5)
Answer:
point (-2,11) does not lie on the given line
Step-by-step explanation:
To find : Which of the following points does not lie on the line ?
Solution :
To determine the point lie on line or not we have to put points in equation if it satisfy then it lie otherwise not.
a) Point (1,8)
Line y=3x+5
Substitute x=1 and y=8
8=3(1)+5
8=8
(1,8) point lie on the line.
b) Point (4,12)
Line y=3x+5
Substitute x=4 and y=17,
17=3(4)+5
17=12+5
17=17
(4,17) point does not lie on the line.
c) point (-2,11)
Line y=3x+5
substitute x=-2 and y=11
11=3(-2)+5
11=-6+5
11 is not equal to -1
d) Point(0.5)
Line y=3x+5
Substitute x=0 and y=5
5=3(0)+5
5=5

Which of the following functions best represents the graph?
f(x) = (x − 2)(x + 1)(x + 2)
f(x) = (x − 1)(x + 1)(x − 4)
f(x) = (x + 2)(x − 1)(x − 2)
f(x) = (x + 1)(x − 1)(x + 4)
Answer:
f(x)=(x-2)(x+2)(x-4)
A man pushes a 10 kg block on a straight horizontal road by applying a force of 5 N. As a result, he moves the block a distance of 10 meters with an acceleration of 0.2 m/s ^ 2 Calculate the work done by the man on the block during motion.
A 200
B 10
C 50
The work done by the man on the block during motion will be 50 Joule. Then the correct option is C.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The work done is given as,
W = F × D
Where F is the force and D is the displacement.
A man pushes a 10 kg block on a straight-level street by applying a power of 5 N. Thus, he moves the block at a distance of 10 meters with a speed increase of 0.2 m/s².
W = 5 × 10
W = 50 Joule
The work done by the man on the block during motion will be 50 Joule. Then the correct option is C.

Think About the Process Use the algebra tiles to help you solve the equation 4x - 8 = 20. What is the first step in solving the equation using algebra tiles? What is the solution to the equation?
Answer:
The first step would be canceling out the eight getting you 4x = 28 and the solution would be x = 7
Step-by-step explanation:
To simplify you need to add the eight to itself to cancel it out but you have to do it to the 20 too making it 28. Then you have to divide 28 by 4 getting you 7.

A)2x - 5y = 22
B)2x - 5y = - 13
C)5x - 2y = 13
D) 5x - 2y = -22
Answer:
Step-by-step explanation:
Point( -4 , 1) ; slope = m = 5
Point-slope form:
y - y1 = m(x -x1)
y - 1 = 5(x - [-4])
y - 1 = 5(x + 4)
y - 1 = 5x + 5*4
y - 1 = 5x + 20
y = 5x + 20 + 1
y= 5x + 21

Explanation:
To get the LCM (lowest common multiple) of 8 and 10, we can multiply the two values together to get 8*10 = 80, then we divide by the GCF (greatest common factor) which is 2 to get to the LCM of 80/2 = 40.
While 80 is a common multiple of 8 and 10, it is not the smallest such value. That would be 40. So that's why we divided by 2.
Another route we can take is to list out the multiples of 8 and 10 like so
multiples of 8 = {8, 16, 24, 32, 40, 48, 56, 64, 72, 80, ...}multiples of 10 = {10, 20, 30, 40, 50, 60, 70, 80, ...}as shown in bold above, the value 40 is in both lists and it is the smallest such common item.
So this tells us that the last two digits are 4 and 0 in that order.
--------------
The GCF of 30 and 75 is 15 since we can say
30 = 15*2
75 = 15*5
Note how the 2 and 5 have no other factors in common, other than 1. This helps us see how 15 is the largest shared factor. So the first two digits are 1 and 5 in that order.
Overall, the four digit code is 1540.

Plot the graph for the equation2y+6=0 , and then select the matching graph below.
Answer:
y = -3
Step-by-step explanation:
2y + 6 = 0
2y = -6
y = -3
Since it's just y = -3, there is NO SLOPE and it's just one straight line going horizontally.
So just pick the graph where it's a horizontal line that only goes through the y-axises of -3 (i.e (0, -3), (1, -3), and etc)

Aaron and two friends went to the movies and spent a
total of $33. The group bought a box of popcorn to
share that cost $ 6. What was the cost of each movie
ticket?
Answer:
6 + (t x 2) = 33
T = Ticket Cost
6 - 6 + (t x 2) = 33 - 6
t x 2 = 27
t x 2/2 = 27/2
t = 13.5
Each ticket cost 13.50$
