The cost of 2 tables and 3 chairs is $705. If the table costs $40 more than the chair, how much does a table cost?
Answers
Answer:
Step-by-step explanation:
2 tables and 3 chairs is $705
Let t stand for table and c stand for chair
3c + 2t = 705
We are told that the table costs $40 more than the chair, so t = c + 40
Now we can insert this into the equation
3c + 2(c + 40) = 705
The next step is to distribute the 2
3c + 2c + 80 = 705
Then combine like terms
5c + 80 = 705
To get the variable by itself, you have to subtract the 80 from both sides.
5c = 705 - 80
5c = 625
This means that 5 chairs costs $625.
Divided both sides by 5 to isolate the variable
c = 625/5
c = 125
Great, now you know the cost of one chair, $125!
The question is asking how much a table costs, and we know that a table costs $40 more than a chair.
A table costs $125 + $40
A table costs $165

a journey by bus takes 45 mins at 40km/h how fast must a car go to undertake the same journey in 25 mins
Answers
Answer:
72km/h
Step-by-step explanation:
Bus - 45 mins at 40km/h
Car - 25 mins at ?
First, find the distance travelled by the bus (since, the journey of the two vehicles are the same, the distance would be the same as well)
distance = speed × timedistance = 40 × 3/4 (45 mins = 3/4 of an hour (45 ÷ 60))distance = 30kmNow we can find the speed of the car using the equation
speed = distance ÷ timespeed = 30 ÷ 5/12 (25 mins = 5/12 of an hour (25 ÷ 60))speed = 72km/hHow to find the slope
(In general)
Answers
Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: Slope =riserun Slope = rise run .

12. The function t = 19m + 65 represents the temperature t (in degrees Fahrenheit)
of an oven after preheating for m minutes.
Answers
The temperature in Fahrenheit after preheating for 2 minutes is 103⁰F
The question looks incomplete but we can as well find the temperature in Fahrenheit after preheating for 2 minutes
Give the function t = 19m + 65 that represents the temperature t (in degrees Fahrenheit) of an oven after preheating for m minutes.
If t = 2,
t = 19(2) + 65
t = 38 + 65
t = 103⁰F
Hence the temperature in Fahrenheit after preheating for 2 minutes is 103⁰F

en una reunión de 162 alumnos había 15 hombres mas que 6 veces las mujeres ¿cuantos hombres y cuantas mujeres habra?
Answers
This shows that there are 141 men and 21 women in the meeting
Let the number of men present be x
Let the number of women present be y
If the total number of students present in the meeting is 162, hence;
x + y = 162 ............ 1
If there were 15 men more than 6 times the women, then;
x = 6y + 15 ...................2
Substitute equation 2 into 1:
6y + 15 + y = 162
7y + 15 = 162
7y = 162 - 15
7y = 147
y = 21
Recall that x = 6y + 15
x = 6(21) + 15
x = 126 + 15
x = 141
This shows that there are 141 men and 21 women in the meeting
