Answer:
The correct unit rate would be 13 minutes/6 problems (written like a fraction)
or it could be 1 problem/2.17 minutes
Step-by-step explanation:
Unit rates are just a time frame over a measurable occurrence, like math problems or distances. The most common example of a unit rate would be speed limits, like 15 miles/1 hour. So to make a unit rate out of the word problem you simply write out the numbers and units like a fraction, and simplify it if necessary.
Answer:
B is the answer
Step-by-step explanation:
because if you multiply 8 times 17 you will get the answer! hope this helped!!!!
The first line equation: y = -2/7x - 5; m1 = -7/2
The second line passes through (2,4) and is perpendicular to the first line.
Therefore,
The gradient of first line = -1/m1 = -1/(-2/7) = 7/2
Then, the equation of the second line is;
y = 7/2x+b
Substituting for the coordinates given;
4 = 7/2(2)+b
4 = 7+b
b = 4-7 = -3
Therefore, the equation of the second line is;
y = 7/2x - 3
In standard form, the equation this equation can be written as:
y(2) = 7x - 3(2)
2y = 7x - 6
7x -2y - 6 = 0 -----> standard form.
X+(x+1)+(x+2)=72
3x=72-3
3x=69
X=23
23+24+25= 72
