  • Answer:

<em>40</em>

  • Step-by-step explanation:

<em>2 + 10 = 24</em>

<em>2(2 + 10) = 2×12 = 24</em>

<em>3 + 6 = 27</em>

<em>3(3 + 6) = 3×9 = 27</em>

<em>7 + 2 = 63</em>

<em>7(7 + 2) = 7×9 = 63</em>

<em>5 + 3 = 40</em>

<em>5(5 + 3) = 5×8 = 40</em>

Answer:

y= -x+5

Step-by-step explanation:

<em>The</em><em> </em><em>slop</em><em>e</em><em> </em><em>of</em><em> </em><em>th</em><em>e</em><em> </em><em>two</em><em> </em><em>paral</em><em>lel</em><em> </em><em>lin</em><em>es</em><em> </em><em>is</em><em> </em><em>equ</em><em>al</em>

<em>so</em><em>,</em><em> the</em><em> slope</em><em> of</em><em> </em>

<em>y</em><em>=</em><em>-x-3</em><em> </em><em>is</em><em> </em><em>-</em><em>1</em><em> </em>

<em>slo</em><em>pe</em><em>=</em><em>y2-y1</em><em>/</em><em>x2-x1</em><em>=</em><em>-</em><em>3</em><em>-</em><em>1</em><em>5</em><em>/</em><em>8</em><em>-</em><em>-</em><em>1</em><em>0</em><em>=</em><em>-</em><em>1</em>

Solve 5c 4 = -26 <br> a. 6 <br> b. -6 <br> c. -4.4 <br> d. 3
lakkis [162]
Simplifying 5C + -4 + -2C + 1 = 8C + 2 Reorder the terms: -4 + 1 + 5C + -2C = 8C + 2 Combine like terms: -4 + 1 = -3 -3 + 5C + -2C = 8C + 2 Combine like terms: 5C + -2C = 3C -3 + 3C = 8C + 2 Reorder the terms: -3 + 3C = 2 + 8C Solving -3 + 3C = 2 + 8C Solving for variable 'C'. Move all terms containing C to the left, all other terms to the right. Add '-8C' to each side of the equation. -3 + 3C + -8C = 2 + 8C + -8C Combine like terms: 3C + -8C = -5C<span>-3 + -5C = 2 + 8C + -8C Combine like terms: 8C + -8C = 0 -3 + -5C = 2 + 0 -3 + -5C = 2 Add '3' to each side of the equation. -3 + 3 + -5C = 2 + 3 Combine like terms: -3 + 3 = 0 0 + -5C = 2 + 3 -5C = 2 + 3 Combine like terms: 2 + 3 = 5 -5C = 5 Divide each side by '-5'. C = -1 Simplifying C = -1</span>
