Answer:
56
Step-by-step explanation:
The angular sum of a triangle is 180 and we know 2 angles so we just add them together and subtract that from 180 for the last angle measure.
90+34 = 124
180-124=56
To simplify the expression (5x^2 - 21x - 20) / (5x^2 - 16x - 16), we can check if there are terms that are needed to be added or subtracted. In this case, there are none. We just check the factors of each polynomial above and below. The factored equation of the numerator is (x-5)*(x + 4/5) while that below is (x-4)* (x + 4/5). In this case, we cancel <span>(x + 4/5). Hence the answer is (x-5) / (x-4)</span>

Answer:
He saved $25.
Step-by-step explanation:
- If Rob saves $5 for every $16 he earns, he is saving the folowing franction of his income: .
- Then if his income equals $16, he will save .
- If his income is $80, he will save
- Another way to understand this problem would be to think that . Then, receiving $80 is the same as receiving 5 times $16. If he saves $5 for every $16 he receives, he would save 5 times $5 = $25.
Answer:(-5,-6)
Step-by-step explanation:
Solve for one variable then solve for the other. Don’t worry you will get a big fraction before you get to the whole number.
