Solve the equation 2(x-4)=-22
Tcecarenko [31]

Hello Lexi!

<u><em>Answer:  ⇒⇒⇒⇒⇒⇒ x=-7</em></u>

__________________________________________________________

Step-by-step explanation:

First you had to divide by 2 from both sides of equation.

\frac{2(x-4)}{2}=\frac{-22}{2}

Simplify.

\frac{2(x-4)}{2}=x-4

\frac{2(x-4)}{2}

Divide by the numbers.

\frac{2}{2}=1

=x-4

\frac{-22}{2}=-11

Apply the fraction rule.

\frac{-22}{2}

=-\frac{22}{2}

Then you divide by the number.

\frac{22}{2}=11

=-11

x-4=-11

Add by 4 from both sides of equation.

x-4+4=-11+4

Simplify it should be the correct answer.

x=-7

Dennis_Churaev [7]

Answer: 17/7

Step-by-step explanation: Step 1: Simplify both sides of the equation. y+4/15 + 2y−5/5 = 2/5 1/15 y+ 4/15 + 2/5 y+−1= 2/5 (Distribute) ( 1/15 y+ 2/5 y)+( 4/15 +−1)= 2/5 (Combine Like Terms) 7/15 y+ −11/15 = 2/5 7/15 y+ −11/15 = 2/5 Step 2: Add 11/15 to both sides. 7/15 y+ −11/15 + 11/15 = 2/5 + 11/15 7 15 y= 17/15

Solve the equation and check your answer. 0.95 t plus 0.05 left parenthesis 100 minus t right parenthesis equals 0.49 left paren
Triss [41]
<h2>Answer:</h2>

The value of t is:

                     t=48.8889

<h2>Step-by-step explanation:</h2>

We are asked to solve the linear equation in terms of variable t.

The equation is given by:

0.95t+0.05(100-t)=0.49(100)

Firstly we will solve the parentheses term in the left and right hand side of the equality as follows:

0.95t+0.05\times 100-0.05t=49

Now we combine the like terms on the left side of equality by:

0.95t-0.05t+5=49\\\\i.e.\\\\0.90t+5=49

Now we subtract both side of the equation by 5 to get:

0.90t=44

Now on dividing both side of the equation by 0.90 we get:

t=\dfrac{44}{0.90}\\\\i.e.\\\\t=48.8889

Hence, the value of t is:   48.8889

2x - y2<br> Z-5<br> Evaluate when x = 2, y = 4<br> z=3
kolezko [41]

Answer:

Putting the value in x = 2 , y =4 in 2x - 2y we get,

2 × 2 - 4× 2= 4-8 = -4

Putting the value in z = 3 in z - 5 we get,

z - 5 = 3 - 5 = -2
