Answer:
72.25
Step-by-step explanation:
y = 1/7x + 4
1/7 * a2 = -1
a2 = -7
y = -7x + b
A = (-1, 5)
-7 * (-1) + b = 5
7 + b = 5
b = -2
<em><u>y </u></em><em><u>=</u></em><em><u> </u></em><em><u>-7x </u></em><em><u>-</u></em><em><u> </u></em><em><u>2</u></em>
Answer:
For problem 17a) your answer is: x=11.5 degrees
Step-by-step explanation:
1. Measure of angle BCA will be 180°-124°=46°
2. In triangle BCA, you now have two angles. 46 degrees, and 2x.
3. Measure of angle ABE is an exterior angle of triangle BCA
4. Using the exterior angle theorem, angle ABE=angle BCA+angle BAC
5. substitute!! 2x+46=6x
6. move 2x over and then divide by 4, you get x=11.5°
7. You can plug the answer back in to check if it correct!! have a nice day :>
<span>So we want to know the number of teachers the university should have if the ratio of students to teachers is 14:1 and the number of students is 896. If x is the number of teachers: 14/1=896/x. Now we solve for x: Lets multiply both sides with x: x*(14/1)=896 and divide both sides by 14 and we get: x=896/14 and x=64. So the university should have 64 teachers.</span>
