A 5" * 7" image reduced by 20% in scale to 80% of the original size will be 4" * 5.6". Roughly the size of a large flash card.
Brand X costs $1.56 for 12 ounces
Brand X: cost of each ounce = $1.56 / 12 = $0.13
Brand Y costs 2 cents more per ounce, so the cost of brand Y per ounce= $0.13 + $0.02 = $0.15
The cost of 15 ounces of brand Y = $0.15 x 15 = $2.25
Answer
$2.25
Answer:
Step-by-step explanation:
<u>Problem 1:</u>
The angles 
and 
are corresponding, and thus are equal to each other. We can then set up the following equation:
.
<u>Problem 2:</u>
The angles 
and 
are supplementary, meaning they add up to 
. Therefore, we have the following equation:
.
X equals 2 and Y equals 1

<em>First evaluate the operations inside of the brackets</em>
-8 + 2[5 + (-4 + 1)2] <em>evaluate (-4 +1) because it is surrounded by parenthesis</em>
-8 + 2[2 + (-3)2]) <em>multiply (-3)2
</em>-8 + 2[2 - 6] <em>subtract 2 - 6 because it is surrounded by the brackets (parenthesis)
</em>-8 + 2(-4) <em>multiply 2(-4)</em>
<em>-8 - 8
-16</em>
