What is Linear Equation in 2 variables?

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c = 0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

Given data ,

The value of C = m + 1

The value of B = m + 5

To calculate the value of 2 C + 3 B , substitute the value of B and C in the expression , we get

2 C + 3 B = 2 ( m + 1 ) + 3 ( m + 5 )

               = 2 m + 2 + 3 m + 15

               = 5 m + 17

Therefore , 2 C + 5 B = 5 m + 17

Hence , the expression 2 C + 3 B equals 5 m + 17 in standard form

Answer:

936mm^2

Step-by-step explanation:

Surface area of cuboid 20 mm 8mm 11mm

Surface area of the cuboid=2(20×8+8×11+11×20)

=2(160+88+×220)

=2(468)

=936mm^2

So the answer is936mm^2

Starting with some solution of volume v and an alcohol concentration of 100c % , if you add 180 mL of 45% isopropyl to it, you get a mixture with a total volume of 180 mL + v.

Each mL of the starting solution contains c mL of alcohol. For example, if the concentration of the starting solution is 80% (so c = 0.8), then each mL contains 80% = 0.8 of one mL of alcohol.

Similarly, each mL of the added solution with 45% concentration contains 0.45 mL of alcohol.

You want the new solution to have a concentration of 70%, so that the ratio of the amount of alcohol in it to the total volume is 70%, meaning

cv + 0.45 (180 mL) = 0.7 (180 mL + v)

and you want to solve for v :

cv + 81 mL = 126 mL + 0.7v

cv - 0.7v = 126 mL - 81 mL

(c - 0.7) v = 45 mL

v = (45 mL) / (c - 0.7)

Judging by context clues, c lies somewhere between 0.7 and 1. (It can't be less than 0.7 because mixing this solution with any other solution of smaller concentration will never yield a solution of higher concentration.)

If, for example, c = 0.8, so that your starting solution is at 80% concentration, then you would need

v = (45 mL) / (0.8 - 0.7) = 450 mL

to be mixed with 180 mL of 45% solution to end up with 180 mL + 450 mL = 630 mL of 70% solution.

As another example, if you're mixing pure alcohol, so that c = 1, you would need

v = (45 mL) / (1 - 0.7) = 150 mL

to make a 180 mL + 150 mL = 330 mL batch of 70% solution. The fact that you would need less of a higher concentration solution is not surprising.

Answer: y=1, x=11

Step-by-step explanation: make x in one side in an equation and substitute it in the other and get the value of y then substitute y in one of the equations and get the value of x

x= 8+3y

8+3y+6y=17

9y=9

y=1

X=11

Answer:

1) 16

2) 35

3) 60 degrees

4) 72 degrees

5) (x+7)= 55 y= 70

Step-by-step explanation:

1) Special Triangle - All angles are 60 degrees, so that means all sides are the same length

2) You know that those two angles at the end are the same, so that means each of those side lengths are mirrored.

3) Special Triangle - Each side is the same, so all angles would be 60 degrees

4) You know that those two sides are the same, so their angles would be mirrored

5) You know that those two sides are the same, so their angles would be mirrored, to get 55 on both bottom sides. 55+55= 110 so, you'd need 70 degrees left to make it a triangle as all triangles are fully 180 degrees.

Answer:

437.90

Step-by-step explanation:

you add the negative numbers together, then the positive numbers. you take the answers from those and subtract them from each other.

The overall loss for the first four months the deli was open is $-437.90.

A firm has a profit when its income is greater than the cost. A loss is recorded when income is less than the total costs. A profit is represented with a positive sign (+) and a loss is represented with a negative sign (-).

In order to determine the overall profit or loss for the first four months add profits and subtract losses.

+ 724.37 + 3,912.26  - 1,051.51 - 4,023.02 = $-437.90.

Costs exceeds revenue so the Deli earns a loss of $437.90.

Answer:

Bruh

Step-by-step explanation:

Im so confused.... lol im not any help

What you're looking for is to simplyfy the like terms and then isolate the variable. So basically, write everything down and solve it like normal. We know that straight lines are worth 180° and right angles are 90° so that's what's gonna be on one side of the equal sign, and all the other numbers on the other side. Like this:

8.

180 = x + 1 + 3x + 9

180 = 4x + 10

170 = 4x

42.5 = x

If it's hard to see what I'm doing, just write the first part out and solve like regular algebra then check if you got the same answer.

Good luck :)
