<u>Given</u>:
Line m is parallel to line n.
The measure of ∠1 is (4x + 15)°
The measure of ∠2 is (9x + 35)°
We need to determine the measure of ∠1
<u>Value of x:</u>
From the figure, it is obvious that ∠1 and ∠2 are linear pairs.
Thus, we have;
Substituting the measures of ∠1 and ∠2, we get;
Thus, the value of x is 10.
<u>Measure of ∠1:</u>
The measure of ∠1 can be determined by substituting x = 10 in the measure of ∠1
Thus, we have;
Thus, the measure of ∠1 is 55°
To find the answer, we just simply use PEMDAS, which means:
Parentheses
Exponents
Multiplication
(and/or)
Division
Addition
(and/or)
Subtraction
Solve the problem in this order. Since no operations are in the parentheses, we can skip that. The first operation we will do is multiplication. I can't really explain multiplication here, but you hopefully already know it, so multiply -4.31 by 3.09. Although there are negatives and decimals, treat it as a normal multiplication problem while doing the math.
This will give you -13.3179, just move the decimal point down, and since a positive is being multiplied by a negative, the answer is negative. Once you have this number, just add it to -0.98. This is the same as subtracting, since it is negative, so in other words, just subtract 0.98 from -13.3179, and you have your answer.
This would be -14.2979, or roughly -14.2.
Hope this helps! :)
Answer: $65
Step-by-step explanation:
The store is having a 20% off sale.
Mai buys an item and saves $13.
This means that $13 is 20% of the price of the item that Mai bought.
Assume the original price is x. Expression is:
x * 20% = 13
x = 13/20%
x = $65
