Answer:
A. 18 sit-ups in one minute
B. 30 doors per hour
D. 18 words per minute
F. $30 per night
C. 3.5 miles per hour
E. $10.50 per pair of pants
Step-by-step explanation:
A. 36/2 = 18
B. 15 * 2 = 30
D. 72/4 = 18
F. 150/5 = 30
C. 10.5/3 = 3.5
E. 31.50/3 = 10.50
Answer:
its either 2/9 or 2/3
Step-by-step explanation:
I solved the top part and got 2/3 and i solved the bottom part and got 1/3 and you can multiply 2/3 and 1/3 and got 2/9
Since the values are the same on both sides the matrix value is a=1
Substitute y=4x to the second equation:
x^2 + (4x)^2 = 17
x^2 + 16x^2 = 17
17x^2 = 17
x^2 = 17/17
x^2 = 1
x = 1 and -1
When x=1, y=4(1) = 4
When x=-1, y=4(-1) = -4
Thus the solutions would be (1,4) and (-1,-4). That would correspond to D. and A.
