Answer:

Step-by-step explanation:
The measure of angle A is ...
180° -55° -45° = 80°
From largest to smallest, the angles are ∠A, ∠C, ∠B. Then their opposite sides will be in order from longest to shortest:

Answer:
(D)Jaleel's method is correct because 2(x-2)=2x-4.
Step-by-step explanation:
Jaleel and Lisa are simplifying the expression 2(x-2)+2 as shown.


We can see that Jaleel's method is correct because:
2(x-2)=2x-4.
When you expand, you must multiply the term outside by all the terms inside the bracket.
The correct option is D.
85 divided by 17=5 so every 1% of students at the school comprise of 5 students, to find the total number of students we need to multiply 100 by 5 making 500, so there would be 500 students at park street middle school for the number of students with blue eyes to match the national statistic.
Answer:
50 nickels, 20 quarters.
Step-by-step explanation:
System of equations (q = # of quarters, n = # of nickels):
<em>q + n = 70, 0.25q + 0.05n = 7.50</em>
the first equation can be changed to q = 70 - n, so we are able to <em>substitute q with 70 - n</em>.
So, it will look like <em>0.25*70 - 0.25n + 0.05n = 7.50</em>. This can be simplified to <em>0.2n = 10</em>, which means that n = 50.
Knowing that we can solve <em>q + 50 = 70</em>, which means that q = 20.
