Answer: 67
Step-by-step explanation:
First You need to add 60+53 together
once you get 113 from that you need to subtract that from 180(due to the fact a triangle=180
Once you subtract 113 from 180 you get 67.
Answer:
7m
Step-by-step explanation:
product means multiplication
7×m = 7m
Answer: 
<u>Step-by-step explanation:</u>
The vertex form of a parabola is: y = a(x - h)² + k where
- (h, k) is the vertex
NOTE: p is the distance from the vertex to the focus
The vertex (h, k) is (2, -3)
Insert those values into the vertex formula to get:
79. Set up an equation to solve this problem. Suppose she needs at least a score of x points. Her current total scores is 89+65+68+88=310. Her total score will be 310+2x (since final exams counts as two tests). The average score is total points divided by number of tests, and it has be bigger or equal to 78, so (310+2x)/6>=78. We solve it and get x=79. She has to score at least 79 on her final exam in order to jhave an overall average of 78.
Answer:
A = 1/2
Step-by-step explanation:
"A+6=9-5A" is already an equation, and your task here is to solve it for A.
Adding 5A to both sides results in
A + 5A + 6 = 9, or
6A + 6 = 9.
Subtracting 6 from both sides results in
6A = 3.
Thus, A = 3/6, or, in simplest terms, A = 1/2.
