Answer:
1100
2200
Step-by-step explanation:
Since speed is constant, the distance is proportional to the time. We notice that the number in the second column is 1650/3 = 550 times the number in the first column, so the two missing numbers are ...
2 × 550 = 1100
4 × 550 = 2200

Answer:
the first one is 3
the second one is 7
the third one is -2
and the last one is -3
Step-by-step explanation:
The equation is matched with its solutions below;
1/4x + 5/3x - 4 = 2 - 1/12x; x = 33.2b - 4.7 = 3b - 3.3; b = 74.6y - y + 4 = y - 1.2; y = -27.5c - 2.5c + 8 = - 7; c = -3What is the solution to the equation?1/4x + 5/3x - 4 = 2 - 1/12x
combine like terms
1/4x + 5/3x + 1/12x = 2 + 4
(3x+20x+x) / 12 = 6
24/12x = 6
2x = 6
Divide both sides by 2
x = 6/2
x = 3
3.2b - 4.7 = 3b - 3.3
combine like terms
3.2b - 3b = -3.3 + 4.7
0.2b = 1.4
divide both sides by 0.2
b = 1.4 / 0.2
b = 7
4.6y - y + 4 = y - 1.2
combine like terms
4.6y - y - y = - 1.2 - 4
2.6y = - 5.2
divide both sides by 2.6
y = -5.2 / 2.6
y = -2
7.5c - 2.5c + 8 = - 7
5c = -7 - 8
5c = -15
divide both sides by 5
c = -15/5
c = -3

Omari and his two cousins received the same amount of money to go to the movies. Each boy spent $15. Afterward, the boys had $30.75 altogether. How much money did each boy receive?
Answers
Answer:
Each boy recieved $25.25 each
Step-by-step explanation:
First, you add up all the money the 3 boys spent.
15+15+15=45
Then you add the sum of the equation to the amount all the boys had afterward.
45+30.75=75.75
Finally, you divide that product to 3 boys.
75.75/3=25.25
Therfore the answer is $25.25 each.

Triangle ABC has the coordinates A(-3, -2), B(2, 4) and C(2,-2). What is the area of triangle ABC?
square units
Answers
Answer: The area is 15 square units
Step-by-step explanation: It is helpful to sketch the coordinates on a graph to get an idea of what the triangle looks like so you can see which side will be the base, and where to get the height. You will see that AB is the hypotenuse, it is a right triangle, so AC can be the base and BC is the height.
Use the differences in x-values of points C & A to get the length of the base: 2-(-3) is 5
Use the differences in y-values of points B & C to get the height:
4-(-2) = 6
Area = bh/2
A = 5×6/2 = 30/2
A = 15 square unts

Answer:
x = 9-8y/7
Step-by-step explanation:
8y+7x=9
Subtract 8y from both sides.

Divide both sides by 7.
7x/7 = 9 - 8y/7
Dividing by 7 undoes the multiplication by 7.
x = 9-8y/7

PLZ HELP ASAP.....Your dad is researching landscaping companies to come put new mulch out for the year. The first company charges $100 just to come out, plus $10 per bag of mulch, m, needed. The second company doesn’t charge to come out but charges $30 per bag of mulch. After how many bags of mulch will the total cost of each company be the same?
Answers
Answer: After 5 bags of mulch, the cost for both companies will be the same.
Step-by-step explanation:
The cost for Company can be represented by the equation: y= 10m+100
The cost for Company B can be represented by the equation: y= 30m
To find the amount of mulch, their cost needs to be the same, I will solve for m
10m+100=30m
-10m 10m
100=20m
Divide both side by 20
100/20=20m/20
5=m or m=5
So after 5 bags of mulch, the total cost for both companies is the same.

then, we put Sam as math variable "s"
it will be; 5-3 x S
[tex]5 - 3 \times s[/tex]
the total of their age is 28
[tex]5 - 3 \times s = 28[/tex]

it will be 5-S3=28
