Answer:

x = 10

Step-by-step explanation:

Same side interior angles are supplementary (SSIA theorem).

Set the equation equal to 180 then solve for x.

4x + 28 = 68

Solve

68 - 28 = 40

40/4 = 10

x = 10

Answer:

Step-by-step explanation:

112 + 4x + 28 = 180°

140 + 4x = 180°

4x = 180 - 140

x = 10

Laura has already baked 9 pies, and she canbake 2 pies with each additional cup ofsugar she buys. With 14 additional cups ofsuga

qaws [65]

let x represent the number of cups of additional cups of sugar and y represents the total number of pies she can bake.

Given that;

"Laura has already baked 9 pies, and she can bake 2 pies with each additional cup of sugar she buys"

$y=9+2x$

With 14 additional cups of sugar;

$x=14$

substituting the value of x;

$\begin{gathered} y=9+2(14) \\ y=9+28 \\ y=37 \end{gathered}$

Therefore, the total number of pies Laura can Bake with 14 additional cups of sugar is;

$undefined$
