Answer:

if you are being asked what the values of the x and y variables are, x=5/2 and y=4

Step-by-step explanation:

In order to solve this problem you will want to isolate one of the two variables in both equations.

I isolated the y variable in both equations so you have:

4x+y=14, when you isolate the y variable, you will get: y=-4x+14

6x-3y=3, same procedure isolate y: 6x-3=3y, now simplify so you only have y: 2x-1=y.

Now that you have the two equations which a common variable, solve them by making the two equations equal to each other like so:

-4x+14=2x-1, now you want to have all the x variable terms on one side and all the constants on the other, you will add "4x" to each side of the equal sign and then add "1" to each side to leave you with: 15=6x

now divide both sides by 6 to obtain your x value: x=15/6 simplifies to 5/2

then plug your x-value into one of the two equations we made earlier:

y=2x-1

y=2(5/2)-1

y=5-1

y=4

now you have calculated the values of your x and y values

Complete the table for the given rule. hi guys this is question is Rule: y is 1/3 times as large as x x y 0 6 12 y need to know
kari74 [83]

Answer:

The completed table is

x | 0 | 6 | 12

y | 0 | 2 | 4

Step-by-step explanation:

It is given that y is (1/3) as large as x. That is,

y = (x/3)

x | 0 | 6 | 12

y | ? | ? | ?

y = (x/3)

When x = 0,

y = (0/3) = 0

when x = 6,

y = (6/3) = 2

when x = 12,

y = (12/3) = 4

The completed table is thus

x | 0 | 6 | 12

y | 0 | 2 | 4

Hope this Helps!!!

Im kinda confused ;-;​
Ivan

Answer:

42-38

42 + (-38)

-38+42

Step-by-step explanation:

In all of these expressions, the 38 has to be negative because that is what you're taking away from the 48. When you have -(- it turns into a +.

In -42 + 38 the 42 is negative, but that is Emma's total amount so it's positive

With -42 -(-38) they did the just added those two together which would make the 42 still negative and the 38 positive.

THen with 42 + 38 the 38 is being subtracted from what she has so you would not add 38 to her total.

Please help with 9 & 10
aev [14]

9. You can easily get rid of the decimal fraction by multiplying by 10. This will move the decimal point one place to the right in each number.

However, since all the decimal fractions are even numbers of tenths, you can also turn them to integers by multiplying by 5:

... 3x +24 = 36

_____

10. If you can't describe what the parts of your equation represent, you have no business writing it. Saying you can't describe your equation is the same as saying you don't understand the problem.

It is important to be able to describe the parts of the equation just as it is important to be able to say what the problem is telling you, what it is asking, and what your strategy is for solving it. The parts of the equation are intimately tied with those things: they embody the given information and the strategy of your solution.
