Answer: B

Step-by-step explanation: it is the 5 that is being multiplied so the 5 would have the x (leaving A and B) but he wants at least 500 not at most 500. So this makes B the correct answer.

PLEASE HELP IT’S DUE TMR!!
zepelin [54]

Answer:

(a) 1.0792 x 10³

(b) 3.769 x 10³

(c) 9.985 x 10³

This should be the answer to the problems, the rounding part got me confused for a second.

Significant digits are numbers after the decimal that aren't 0. So the 1.0792, the 0 isn't a significant digit.

I went to the grocery store the other day and there were no price tags on anything! I bought 3 loaves of bread and 1 milk jug an
Lostsunrise [7]
To solve this problem, set up and solve a system of equations.  The variables b and m will represent a bread loaf and milk jug, respectively:

\left \{ {{3b + m = 9} \atop {b + 2m =5.5}} \right.

I would solve using substitution.  Take one of the equations and set it equal to one of the variables, for example:

3b + m =9 \\ m = 9 -3b

Now, plug this into the other equation for m and solve for b:

b + 2m =5.5 \\ b + 2(9-3b)= 5.5 \\ b + 18 - 6b = 5.5 \\ -5b + 18 = 5.5 \\ -5b = -12.5 \\ b = 2.5

We now know that a loaf of bread costs $2.50.  Plug this value in for b in the first equation and solve for m:

3b + m = 9 \\ 3(2.5) + m = 9 \\ 7.5+m = 9 \\ m = 1.5

One jug of milk costs $1.50 and one loaf of bread costs $2.50.
