Answer:  The required answer is 3x².

Step-by-step explanation:  We are given that the sum of an expression E and 7x² is 10x².

We are to find the value of the expression E.

According to the given information, we have

E+7x^2=10x^2\\\\\Rightarrow E=10x^2-7x^2\\\\\Rightarrow E=(10-7)x^2\\\\\Rightarrow E=3x^2.

Thus, the required answer is 3x².

2 3/18 - (- 48/18) + (- 4 14/18)

Then we remove parenthesis...

2 3/18 +48/18 - 4 4/18

1/18

You have already saved $55. You can earn $9 per hour at your job. You are saving for a bicycle that costs $199. What inequality
Sveta_85 [38]

y = 9x + 55 because the 9x is the amount you get paid an hour, and to get to the 199 you need to include to rate at which you get paid, and add that to how much you already have saved.

2(x+11) = -26 show all work pls
Degger [83]

Answer:

x = -24

Step-by-step explanation:

First, distribute 2 to all terms within the parenthesis:

2(x + 11) =

2 * x = 2x

2 * 11 = 22

2x + 22 = -26

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

~

First, subtract 22 from both sides of the equation:

2x + 22 (-22) = -26 (-22)

2x = -26 - 22

2x = -48

Next, divide 2 from both sides of the equation:

(2x)/2 = (-48)/2

x = -48/2

x = -24

x = -24 is your answer.
