B. 5:10 because 15-5=10 which is the number of pencils with erasers and the 5 left are the amount of pencils which are missing an eraser
Answer:
12
Step-by-step explanation:
Let's put the equations in standard form. For the first equation, we have:
−11y=6(z+1)-13y
2y−6z=6
y−3z=3
The second equation is:
4y−24=c(z−1)
4y−cz=24−c
If we multiply the first equation by 4, we get:
4y-12z=12
Comparing the two equations, we see that if c=12, both equations will be the same and there will be infinitely many solutions.
The correct value of c is 12.
Answer:
C is greatest to fraction
You want an estimate, not an actual answer. But just in case you think that way, the actual answer is 34/8 - 16/3 - 14/9 = -2 23/36
34/8 = about 4 3/4
16/3 = about 5 1/3
14/9 i= about 1 5/9
So the answer is about 5 - 5 - 1 1/2 which is about (- 1 1/2) That's your answer. Remember you are estimating. I don't know that you can get it much closer without using a calculator.
