Answer:

Step-by-step explanation:

they are different because the x at the end of 'y=3.2x' means times by a different number what i mean by this is for example if you had 5x that then means x is a number that you times to 5 and in a question and example of this would be

if x = 5 work out

5x that would give an answer of 25

hope this helps :)

How to estimate 2 5/6, first one to answer will be marked brainliest
RideAnS [48]

Answer:

If your saying estimate this number in a decimal without calculators I think I might be able to help as illustrated below:

Step-by-step explanation:

2 5/6 shows that the whole number will be a 2. The 5/6 is a decimal below one as it is not one whole fraction. This means that we have to estimate the value of 5/6 and add that value to the number 2. 1/3 is a common fraction that is equal to about 0.33. This is because 0.33 + 0.33 + 0.33 is almost 1, which means 1/3 of one is indeed equal to 0.33.

<u>This means we divide 0.33 by 2, because that would be equal to (1/3)/(2), or 1/6. </u>0.33/2 seems like it would be 16.5. 16.5 * 5, as in 5/6, would be 82.5.

I would then say that the estimate of 2 5/6 is 2.83.

Which equations are true?<br>A: -x = -x + x + 0<br>B: -x = 0 + (-x)<br>C: None Of The Above ​
Leto [7]
Answer: B
Explanation: if you look at A and try to combine like terms, you will add the -x on the right side the the one on the left, cancelling out the x on the left. then you have 0=x+0, and unless x=0, it is not true.
With B, when you add x to the -x, you cancel it out, giving you 0=0, which is true. hope it helps!

A coffee mixture has beans that sell for $1.35 per pound and beans that sell for $1.05 per pound. If 120 pounds of beans create
insens350 [35]
Let e be the amount of 1.35 beans and c be the amount of 1.05 beans...

(1.35e+1.05c)/120=1.15  we know e+c=120, so e=120-c making the equation:

(1.35(120-c)+1.05c)/120=1.15

(162-1.35c+1.05c)/120=1.15

162-0.3c=138

-0.3c=-24

c=80, and since e=120-c, e=40 so:

80 lb of the $1.05 beans are mixed with 40 lb of the $1.35 beans to produce a 120 lb mixture worth $1.15 per pound.
