Answer:

x = 0.5

Step-by-step explanation:

2.2X + 2.2 = 1.1

subtract both sides by 2.2

2.2X = -1.1

divide both sides by 2.2

we get x = 0.5 or 1/2

Answer:

-\frac{1}{2}

Step-by-step explanation:

Here we are given an equation and we are required to solve it for x .

Subtract 2.2 from both sides we get

2.2x + 2.2 - 2.2 = 1.1 - 2.2\\2.2x=-1.1

Now dividing both sides by 2.2 we get

\frac{2.2}{2.2}\times x=-\frac{1.1}{2.2}\\x=-\frac{1}{2}

If b=p+5 and a=p^2+10p+1 find an expression that equals 2b+3a in standard form
olya-2409 [2.1K]

Answer:

3p² + 32p + 13

Step-by-step explanation:

Okay, so lets first solve for 2b. 2b = 2(p + 5), which is equal to 2p + 10. Now, let's solve for 3a. 3a = 3(p² + 10p +1), simplifying to 3p² + 30p +3. After adding 2b and 3a, we are able to get 2p + 10 + 3p² + 30p + 3 = 3p² + 32p + 13

Solve for W.<br><br> 4w-4+2(5w+8)=-2(w+3)<br><br> Simplify your answer as much as possible.
gayaneshka [121]

Answer:

w = -\frac{9}{8}

Step-by-step explanation:

The question is  4w-4+2(5w+8)=-2(w+3)

We can first use distributive property to simplify, the distributive property is  a(b+c)=ab+ac

Thus we have:

4w-4+2(5w+8)=-2(w+3)\\4w-4+10w+16=-2w-6

<em>Now we combine like terms and simplify to get the final answer for w</em><em>.</em>

4w-4+10w+16=-2w-6\\14w+12=-2w-6\\14w+2w=-6-12\\16w=-18\\w=\frac{-18}{16}\\w=-\frac{9}{8}

Thus, w = -\frac{9}{8}

Solve the system of equations using substitution<br> 4x + 2y = 16<br> =−12+5
mario62 [17]

Answer:

x=\frac{70}{11},\:y=\frac{20}{11}

Step-by-step explanation:

\begin{bmatrix}4x+2y=16y\\ y=-\frac{1}{2}x+5\end{bmatrix}

\mathrm{Substitute\:}y=-\frac{1}{2}x+5

\begin{bmatrix}4x+2\left(-\frac{1}{2}x+5\right)=16\left(-\frac{1}{2}x+5\right)\end{bmatrix}

Simplify

\begin{bmatrix}3x+10=16\left(-\frac{1}{2}x+5\right)\end{bmatrix}

Isolate x for 3x+10=16(-1/2x+5): x=\frac{70}{11}

\mathrm{For\:}y=-\frac{1}{2}x+5

\mathrm{Substitute\:}x=\frac{70}{11}

y=-\frac{1}{2}\cdot \frac{70}{11}+5

-\frac{1}{2}*\frac{70}{11}+5=\frac{20}{11}

y=\frac{20}{11}

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}

x=\frac{70}{11},\:y=\frac{20}{11}
