6th grade math help me plzzzz

Answer:

a) x = -2/3    y = -26/3 or -8 2/3

b) x = 12      y = 5

Step-by-step explanation:

a) since both equations begin with 'y =' you can set them equal to each other

4x - 6 = x - 8

3x = -2

x = -2/3

sub x value to find y:

y = 4(-2/3) - 6

   = -8/3 + (-18/3)

   = -26/3  

Answer:

no because you can put 2 into 5/2 2 times so it would be 2 and 1/2 and 9 is bigger then that

Answer: 3a - 7

Step-by-step explanation:

(-4a - 3) + (7a - 4)

Combine like terms

-4a + 7a - 3 - 4

3a - 7

Hope this helped!

7 a -4 =30

Move all terms not containing  

a

to the right side of the equation.

Tap for more steps...

7

a = 34

Divide each term by  

7

and simplify.

Tap for more steps...

a = 34 7

The result can be shown in multiple forms.

Exact Form:

a = 34 7

Decimal Form:

a = 4. 857142

Mixed Number Form:

a

=

4  6/ 7

In this case, we need to substitute n with 10.

So, it is like this: f(10) = 3(10) + 4

f(10) = 3(10) + 4

f(10) = 30 + 4

f(10) = 34

Answer: {(0, 1), (2, 3), (4, 5), (7, 8)}

Step-by-step explanation:

For the function:  y = x - 1    (y is one less than x)

If x =1 , y= 0

if x= 3 . y= 2

If x = 5 , y= 4

If x= 8 , y= 7

So it is same as

x y

1 0

3 2

5 4

8 7

But different from {(0, 1), (2, 3), (4, 5), (7, 8)} [here x is 1 less than y]

So,  the complete statement would be : All of the following represent the same function except {(0, 1), (2, 3), (4, 5), (7, 8)} .

Step-by-step explanation:

ok so its basically like addition the top + the bottom.

3x + 3y = 12

6x + 11y = 14

9x + 15y = 26

now u wat to cancel out

9x + 15y = 26

9                

15y = 26     y = 1.7

9x = 26      x = 2.8

i think this is right i hopw this helps

Answer:

y= -2

x= 6

there you go

Answer:

5/3a+2b is the answer you need to use an the ab/c on your calculator

Answer:

[tex] \frac{4}{3} a - \frac{1}{2} b + \frac{1}{3} a + \frac{5}{2} b \\ = ( \frac{4}{3} + \frac{1}{3} )a + ( \frac{5}{2} - \frac{1}{2} )b \\ = \frac{5}{3} a + \frac{4}{2} b \\ = \frac{5}{3} a + 2b \\ = \frac{5}{3}a + 2b[/tex]

Answer:

Option C

Step-by-step explanation:

[tex] \sqrt{144 {a}^{2} {b}^{4} } [/tex]can be written as[tex] \sqrt{144 \times {a}^{2} \times {b}^{4} } [/tex]

[tex] = > \sqrt{144} \times \sqrt{( {a}^{2}) } \times \sqrt{( {b}^{4}) } [/tex]

[tex] = > 12 \times {a}^{ \frac{2}{2} } \times {b}^{ \frac{4}{2} } [/tex]

[tex] = > 12a {b}^{2} [/tex]

Answer:

0. 42

Step-by-step explanation:

any number greater than 0 is significant if it's exactly 0 or less than 0 is not significant. since it's two significant figures you count the first two numbers greater than 0 which is 0.41 and we have 8 will is greater than 5 which will be rounded to 1 then rounded to 0.41 which makes it 0.42

Answer:

m || n only when the corresponding angles will be equal.

Step-by-step explanation:

Here its only given that vertical angles are equal. But it doesn't prove m || n . If the corresponding angles wouls have been equal , then only we can prove that m || n.

Answer:

18y-6x

Step-by-step explanation:

Multiply what is inside the brackets by what is outside, in this case 3.

Answer:

I'm sure you mean miles, but the car will travel 135 mites.

Step-by-step explanation:

(180/4)3 = 135 miles. The car will be traveling at 45 miles per hour since 180 miles divided by four hours is 45, then you can multiply that by three to get the distance the car will travel in the next three hours. A function that models this equation is f(x)=45x.

Answer:

8 teams each team will have 4 girls and 4 boys

Step-by-step explanation:

We use GCD to solve this

the GCD of 32 and 24 = 8

8 is the greatest number of teams.

each team must have equal number of boys and girls so divided by two

8/2 = 4

4 girls and 4 boys

I have attached how to do GCD.

Answer:

                                                           Solution:

Check batteries=20

Battreies do not have charge=14

Out of the next batteries that you check=70

Expect to not have charge=30

Answer is 30.

Step-by-step explanation:

Number of batteries do not have charge from 20 batteries is 49 batteries

What information do we have?

Number of batteries do not have charge from 20 batteries = 14 batteries

Using ration of total batteries to do not have charge batteries

Number of batteries do not have charge from 70 batteries = 70[14/20]

Number of batteries do not have charge from 70 batteries = 7[7]

Number of batteries do not have charge from 20 batteries = 49 batteries
