To find the answer,we can set an equation:
Let the time he used to drive in the afternoon be y miles.
Time used in the afternoon = y
Time used in morning = y - 70
Total time used = 248
The value of y:
y + (y - 70) = 248
2y-70 = 248
2y = 248+70
2y = 318
y = 318/2
y = 159
Therefore, he droved 159 miles in the afternoon.
Hope it helps!
Hello!
We can find out our answer by plugging in the point (1,1) to see which equation works.
y=1.4(1.2)≠1
y=1.2≠1
y=0.5+0.3≠1
y=0.2+1.2≠1
As you can see, none of these answers are correct. You could make the last equation true by switching 0.2 to -0.2. It may have been a typo, so I would say the best answer is D.
I hope this helps!
Answer:
The correct answer is "50%".
Step-by-step explanation:
The given values are:
Gravel,
= 
Water,
= 
Cement,
= 1
Sand,
= 2
Now,
The total mixture will be:
= 
By substituting the values, we get
= 
= 
= 
hence,
The percentage of sand will be:
= 
= 
= 
%
4^ 2-(3.1+6.4)+4.5
16 − ( 3.1 + 6.4 ) + 4.5
16 − 9.5 + 4.5
6.5 + 4.5
= 11
