We can simplify it by combining like terms
We get -7x -3x = -10x and -10x+8x = -2x
then we get -2x + 2 = -8
-2x = -10
x = 5

(2) Clare said that 4/3:5/2 is 10/3. She reasoned: 4/3.5=20/3 and 20/3:2=10/3.
MissTica

Answer:

The answer is 8/15

Step-by-step explanation:

4/3 divided by 5/2 is the same as 4/3 times 2/5

4/3 times 2/5= 8/15

8/15 is the answer

She is wrong because if you want to do it you have to multiply the fraction with 5 and then MULTIPLY it by 2 not divide it by 2.

Hope this helps :)

Write 19/25 as a terminating decimal
mariarad [96]
Terminating decimals firstly are decimals that finish... 
To transfer 19/25 to a decimal we have to get it out of 100. 
To do this, multiply 19 by 4, and 25 by 4. 
This gives you 76/100.
From here you can easily see the decimal is 0.76. 

= 0.76

Determine if (-1,9) and (-2,6) are solutions to the system of equations: x + y = 8 x2 + y = 10 A) Both are solutions B) Neither
Dahasolnce [82]

Answer:

D) Only (-1,9) is a solution.

Step-by-step explanation:

x+y =8

x^2 + y = 10

Lets check the first point (-1,9)

Put in x =-1 y =9

x+y =8

-1+9 = 8

8 =8

This works

x^2 + y = 10

(-1)^2 +9 =10

1+9 = 10

10 = 10

This works

Lets check the second point (-2,6)

Put in x =-2 y =6

x+y =8

-2+6 = 8

4=8

This  does not work

We can stop now.  (-2,6) cannot be a solution
