What is a linear equation?
A linear equation has one or two variables. No variable in a linear equation is raised to a power greater than 1.No variable is used as the denominator of a fraction. A linear equation is defined as an equation that is written in the form of ax+by=c. When solving the system of linear equations, we will get the values of the variable, which is called the solution of a linear equation.
solving this we will get the valve of Y is x is given.
calculation:-
today distance = 9904 km.
total time is taken = 8 hours.
∴total distance covered in one hour = 9904/8
= 1238 km.

Answer:
Rs 19 1/8
Step-by-step explanation:
Fromm the above question, we are told that:
The cost of 2/3 meters of rope = Rs 12 3/4
We are asked to calculate the cost per meter of rope.
Hence:
2/3 meters of rope = Rs 12 3/4
1 meter of rope = Rs x
Cross Multiply
2/3x = 1 × 12 3/4
x = 12 3/4 ÷ 2/3
x = 51/4 ÷ 2/3
x = 51/4 × 3/2
x = 153/8
x = Rs 19 1/8
Therefore, the Cost per meter of rope = Rs 19 1/8

The population of a city has increased by 38% since it was last measured. If the current population is 89,700, what was the previous population.
Answer:
65000
Step-by-step explanation:
Given data
Let the previous population be x
the increase was by 38%
The expression below describes the current population
38/100*x+ x=89700
0.38x+x= 89700
1.38x= 89700
x= 89700/1.38
x= 65000
Hence the previous population is 65000

Answer:
[tex]y=-\frac{1}{5}x+\frac{6}{5}[/tex]
Step-by-step explanation:
Let's solve for x.
[tex]x+5y=6[/tex]
Step 1: Add -5y to both sides.
[tex]x+5y+-5y=6+-5y[/tex]
[tex]x=-5y+6[/tex]

[tex]x=-5y+6[/tex]
Let's solve for y.
[tex]x+5y=6[/tex]
Step 1: Add -x to both sides.
[tex]x+5y+-x=6+-x[/tex]
[tex]5y=-x+6[/tex]
Step 2: Divide both sides by 5.
[tex]\frac{5y}{5}=\frac{-x+6}{5}[/tex]
[tex]y=\frac{-1}{5} x+\frac{6}{5}[/tex]

Use a unit multiplier to convert 0.37 liters to milliliters.
Answer:
370
Step-by-step explanation:
Multiply the number of liters (L) by 1,000 to find the number of milliliters (mL). There are 1,000 times as many milliliters as there are liters. For instance, say you have 3 liters. Simply multiply 3 liters by 1,000 to get 3,000 milliliters.

B) The y-intercept is located at (0, 70).
C) There is an asymptote at x = 0.
D) The x-intercept is located at (70, 0).
Answer: b the y-intercept is located at (0,70)

Answer:

Step-by-step explanation:
Factor out 1/4.
1/4 - 3/4 x = (1/4)(1 - 3x)
Answer: B
How do we solve this?
Answer:
B is (3, 10)
Step-by-step explanation:
The midpoint of coordinates of the 2 points (x1, y1( and (x2, y2) is
(x1 + x^2) / 2 , (y1 + y2)/2.
So if (x, y) are the coordinates of B we have:
(7 + x)/2 + (2 + y)/2 = 5 + 6
So 7 + x = 2*5 so x = 3
AND 2 + Y = 12 SO y = 10.

Solve for y: LaTeX: \frac{y}{11} = 8
GIVING BRAINLIST!!!
Answer:
y = 88
Step-by-step explanation:
(I'm assuming that by \frac{y}{11} you mean y/11)
You can solve this by multiplying by 11 on both sides. y/11 = 8, so if you multiply by 11 on both sides, you get that y = 8 * 11, so y = 88

12 parents volunteered to
chaperone the dance. If 15% of all
parents polled volunteered, how
many parents were asked to
volunteer?
Answer:
80
Step-by-step explanation:
15/100x=12
3/20x=12
x=12*20/3=80
if my answer helped please mark as brainliest.
Answer:
if 15% of all parents polled volunteered, then 80 parents were asked to volunteer.
Step-by-step explanation:
Okay so basically 12 is 15% of a number therefore 12/? = 15%/100?
So we multiply 12 x 100= 1200
Then divide 1200 ÷ 15 to get your answer.
1200 ÷ 15 = 80
2) Solve the System of Equations using Substitution.
-3x+2y=12
x=2y-8
Answer:
x=-2. y=3
Step-by-step explanation:
So, it tells us that x=2y-8.
Now substitute x into the equation.
-3(2y-8)+2y=12
- 6y+24+2y=12
-4y+24=12
-4y=-12
y=-12/-4
y=3
Now that we know that y=3 substitute y into the second equation equation.
x=2(3)-8
x=6-8
x=-2
So in the end x=-2 and y=3
Hope this helps
Answer:
y=3, and x= -2
Step-by-step explanation:
-3x= -2y+12
x=2y-8
3x=2y-12
3x=6y-24
2y-12=6y-24
-4y=-12
y=3
x= -2
If it costs $300 to tile a 420 square foot room, how much will it cost to tile a
room with 1,050 square feet?
Answer:
750$
Step-by-step explanation:
[tex]Amount= 300*\frac{1050}{420} =750[/tex]
It will cost approximately $750.01 to tile a room with an area of 1,050 square feet.
To find out how much it will cost to tile a room with 1,050 square feet, we can set up a proportion using the given information.
Cost₁: The cost to tile the first room with an area of 420 square feet, which is $300.
Area₁: The area of the first room, which is 420 square feet.
Cost₂: The cost to tile the second room with an unknown area, which we want to find.
Area₂: The area of the second room, which is 1,050 square feet.
We can set up the proportion:
Cost₁ / Area₁ = Cost₂ / Area₂
Substituting the known values:
$300 / 420 sq ft = Cost₂ / 1,050 sq ft
Now we can solve for Cost₂:
Cost₂ = ($300 / 420 sq ft) * 1,050 sq ft
Calculating:
Cost₂ = $0.7143 * 1,050 sq ft
Cost₂ ≈ $750.01
Therefore, it will cost approximately $750.01 to tile a room with an area of 1,050 square feet.
