What is the value of x?
What is the value of y?
Answer:
the value of x and y is 3 and -1 respectively.
Step-by-step explanation:
from the question
let
2x + 3y = 3........................ equation 1
y = 8 - 3x.............................. equation 2
put y = 8 - 3x in equation 1
2x + 3y = 3........................ equation 1
2x + 3 ( 8 - 3x) = 3
2x + 24 - 9x = 3
24 - 7x = 3
24 = 3 + 7x
24 -3 = 7x
21 = 7x
divide both sides by 7
x = 3
put x = 3 in equation 2
y = 8 - 3x.............................. equation 2
y = 8 - 3 ( 3)
y = 8 -9
y = -1
therefore the value of x and y is 3 and -1 respectively.

if f(x) = 3x - 12, what is f(2)?
-6
-18
18
6
Answer: -6
Explanation: In this problem, we're given the function f(x) = 3x - 12 and we're asked to find f(2).
To find f(2) or the value of the function when x equals 0, we simply substitute 2 in for x in our function. So we have f(x) = 3(2) - 12 or 6 - 12 which equals -6.
So f(2) or the value of the function when x equals 2 is -6.
If 3x + 8 = -4, then
evaluate x3 + 5
Answer:
-59
Step-by-step explanation:
x3 is meaningless; I assume you meant x^3.
If that's the case, then:
3x + 8 = -4 is equivalent to 3x = -12, so that x = -4.
Then (-4)^3 + 5 = -64 + 5 = -59
Answer:
-59
Step-by-step explanation:
the question can be solved by some simple mathematical steps.
If 3x + 8 = -4
then, x3 + 5 =?
from 3x + 8 = -4
collect the like terms
3x = -4 - 8
3x = -12
divide both sides by 3
3x/3 = -12/3
x = -4
if x = -4 then to find x3 + 5 will imply that we will insert the value of x = -4 into the x3 + 5
-4 ³ + 5
-64 + 5
= -59
therefore the value of x3 + 5 is solved to be -59

Bobby drives his truck at a rate of 50 to 60 miles per hour.
a. Approximately how far can Bobby drive in 2, 3, 4, and 5 hours?
b. Bobby plans to take an 8-hour trip, which will include a 1-hour stop for
lunch. What is a reasonable distance for Bobby to drive?
a. 2 hours = 100 to 120m
3 hrs = 150 to 180m
4 hrs = 200 to 240m
5 hrs = 250 to 300m
b. 400 to 480 miles
Bobby can drive between 50 times the number of hours and 60 times the number of hours depending on the drive duration. For an 8-hour trip with a 1-hour lunch stop, he drives for 7 hours, covering between 350 and 420 miles.
Explanation:a) Bobby's driving speed varies between 50 to 60 miles per hour. Therefore:
If he drives for 2 hours, at the minimum speed he can cover 50*2=100 miles, and at the maximum speed, he can cover 60*2=120 miles.If he drives for 3 hours, the range is between 50*3=150 miles and 60*3=180 miles.If he drives for 4 hours, the range is between 50*4=200 miles and 60*4=240 miles.And if he drives for 5 hours, the range is between 50*5=250 miles and 60*5=300 miles.b) For an 8-hour trip with a 1-hour stop for lunch, Bobby will effectively be driving for 7 hours. So, the minimum distance he could cover is 50*7=350 miles and the maximum distance is 60*7=420 miles.

Mai spends 7 3/5 hours in school each day. Her lunch period is 30 minutes long, and she spends a total of 42 minutes switching rooms between classes. The rest of her day is spent in 6 classes that are all the same length. How long is each class?
The each class is 64 minutes or 1 hour 4 minutes long.
Step-by-step explanation:
1 hour = 60 minutes.
Total time spent in school = 7 hours+3/5 hour = 7(60) + (3/5)(60) minutes.Total time = 420+36 = 456 minutes.Lunch period = 30 minutes.Time for switching classrooms = 42 minutes.Time spent in 6 classes :
Time spent in 6 classes = Total time - (lunch period + switching classes)
⇒ 456 - (30+42)
⇒ 456 - 72
⇒ 384 minutes.
The Time for each of 6 classes :
Time for each class = Time spent for all 6 classes / 6
⇒ 384/6
⇒ 64 minutes.
⇒ 1 hour 4 minutes.

write an equation of the circle with center 6.-9) and radius 10!
The equation of the given circle is [tex](x-6)^{2}+(y+9)^{2}=100.[/tex]
Step-by-step explanation:
Step 1:
The equation of a circle with its center at (h, k) and a radius of r is given by
[tex](x-h)^{2}+(y-k)^{2}=r^{2}.[/tex]
The h value is the x coordinate and the k value is the y coordinates, so (h, k) is (6, -9).
The radius is given as 10 so [tex]r =10[/tex] and [tex]r^{2} = 100.[/tex]
Step 2:
By substituting the values we know, we get
[tex](x-h)^{2}+(y-k)^{2}=r^{2} = (x-6)^{2}+(y-(-9))^{2}=10^{2}.[/tex]
So the equation of the given circle is
[tex](x-6)^{2}+(y+9)^{2}=100.[/tex]
-4 1/4 divided by 1/2
Answer:
-8.5, or -8 1/2
Step-by-step explanation:
Put it into an improper fraction: -17/4
Multiply: -17/4 * 2/1 (To divide, multiply by reciprocal)
= -34/4
Simplify: -17/2, or -8 1/2
Answer:
-34/4 or -8 1/2
Step-by-step explanation:
First we want to put -4 1/4 so its all a fraction we do this by multiplying 4 to 4 and adding it to the 1 already in the fraction (We can ignore the sign and just add it to the fraction because the entire fraction is negative not just the 4). So we have -17/4
To divide fractions we use keep change flip it is an easier way to divide fractions with out making decimals. We keep the first fraction change the division into multiplication and flip the last fraction, in this case 1/2 becomes 2/1. Now we have
-17/4 * 2/1
Our next step is to multiply the numerators together and the denominators together and then put it back in fraction form.
-17 * 2 = -34
4 * 1 = 4
Our final result is
-34/4
Or if you need it as a mixed number you just divide the 34 into 4 as many times as you can and make that the whole number. 34 doesn't completely fit into 4 but 32 does so we have
-8 2/4 or simplified further
-8 1/2

Skylar got a manicure for $28 and pedicure for $35
salon. If she plans to tip 15%, how much will she pay?
Answer:
$72.45
Step-by-step explanation:
Add the amounts of the manicure and pedicure together: 28 + 35 = 63
Then find 15% of $63. You will need to find the decimal equivalent of 15%. To do this, divide 15 by 100 or move it two decimal places to the right: 15/100 = 0.15
Now, multiply total of the manicure and pedicure, 63, by 0.15: 63 x 0.15 = 9.45
$9.45 will be her tip. To find the total amount Skylar payed, add the tip to the amount spent on the mani/pedi: 63 + 9.45 = 72.45
Skylar will pay $72.45
Hope this helps!
Final answer:
To calculate Skylar's total payment including a 15% tip for her manicure and pedicure, add the cost of both services ($63) and then calculate the tip ($9.45). The total payment is $72.45.
Explanation:
The student's question involves calculating the total cost of a service which includes both a tip and the original prices of the services purchased - in this case, a manicure and a pedicure. To find how much Skylar will pay after tipping 15%, we first need to calculate the total cost of the services before the tip.
Firstly, we add the cost of the manicure ($28) and the pedicure ($35) to get the total cost before the tip:
Manicure = $28Pedicure = $35Total cost before tip = Manicure + Pedicure = $28 + $35 = $63Next, we calculate the amount of the tip by multiplying the total cost by the tip percentage (which we convert from 15% to a decimal by dividing by 100):
Tip percentage = 15%Tip as a decimal = 15% / 100 = 0.15Tip amount = Total cost before tip × Tip as a decimal = $63 × 0.15 = $9.45Finally, we add the original total cost to the tip to find the final amount Skylar will pay:
Final total cost = Total cost before tip + Tip amount = $63 + $9.45 = $72.45So, Skylar will pay $72.45 in total for her manicure and pedicure including a 15% tip.
The mass of an empty container is 3/10kg. When the container is half filled with water, the mass becomes 1 1/10kg. What is the mass of the container when it is completely filled with water
Answer:
1.9 kg
Step-by-step explanation:
Empty container: 3/10 kg = 0.3 kg
Container half filled: 1 1/10 kg = 1.1 kg
Mass of water that fills it halfway: 1.1 kg - 0.3 kg = 0.8 kg
Mass of water that fills it completely: 2 * 0.8 kg = 1.6 kg
Mass of container completely filled with water: 0.3 kg + 1.6 kg = 1.9 kg
