Sam and Tim ordered food for their colleagues at a local restaurant. Sam ordered 3 personal
pan pizzas and 6 burgers for a total of $43.41. Tim ordered 2 personal pan pizzas and 7
burgers for a total of $40.91.
The cost of each pizza was. And the cost of each burger was
Answers
Answer:
burger =$3.99
pan pizza =$6.49
Step-by-step explanation:
3p+6b=43.41⇒eqn 1
2p+7b=40.91⇒eqn 2
eqn 1 * 2
6p+12b=86.82⇒eqn 3
eqn 2 * 3
6p+21b=122.73⇒eqn 4
eqn 4- eqn 3
9b=35.91
b=3.99
sub b=3.99 in eqn 1
3p=43.41-23.94
p=19.47/3
p=6.49
3p + 6b = 43.41
2p + 7b = 40.91
Take twice the first and subtract from three times the second.
9b = 35.91
b = 3.99
Substitute b back in either equation, to get p = 6.49.

Answers
Answer:
Exponents
By Vicki Young
I open up my textbook when I first get out of bed,
Start studying those rules, just like my teacher said!
Recognizing bases, exponents, too.
Exponents must be positive, negatives won't do.
I've got to work these problems, I've got to find a way.
Oh, I feel frantic today!
I start to see a pattern to how these things are done.
I raise to zero power and the answer's always one.
The base just can't be zero - I must remember that.
Just three more rules to learn now and then I can relax.
I'll put it all together, I'll know it pretty soon.
Oh, I feel better at noon!
To multiply same bases, exponents I combine.
Dividing's just the opposite, but then I must decide
To subtract the smaller power, the base correctly place.
The power rule says multiply, parentheses erase.
I know I've got these rules now, I know I've got them right.
Oh, I feel lucky tonight!

Solve for r:
[tex]v = \frac{4}{3}{r}^{3} [/tex]
Solve for v2
[tex]a \: ave = \frac{v2 - v1}{t2 - t1} [/tex]
Answers
Answer:
Solving [tex]v = \frac{4}{3}\pi r^3[/tex] for r gives us: [tex]r=\sqrt[3]{\frac{3v}{4\pi}}[/tex]
Solving [tex]a_{ave} = \frac{v_2-v_1}{t_2-t_1}[/tex] for v2 gives us: [tex]v_2 = (t_2-t_1)a_{ave}+v_1[/tex]
Step-by-step explanation:
Solving an equation for a variable or constant means that we have to isolate the value on one side of the equation or write the whole equation in terms of that variable or constant.
Now,
Solving [tex]v = \frac{4}{3}\pi r^3[/tex] for r
[tex]v = \frac{4}{3}\pi r^3[/tex]
Multiplying whole equation by 3/4
[tex]\frac{3}{4}.v = \frac{3}{4}.\frac{4}{3} \pi r^3[/tex]
[tex]\frac{3}{4}v = \pi r^3[/tex]
Dividing by Pi on both sides
[tex]\frac{3v}{4\pi} = \frac{\pi r^3}{\pi}\\\frac{3v}{4\pi} = r^3[/tex]
Taking cube root on both sides
[tex]\sqrt[3]{r^3} = \sqrt[3]{\frac{3v}{4\pi}} \\r = \sqrt[3]{\frac{3v}{4\pi}}[/tex]
Now
Solving [tex]a_{ave} = \frac{v_2-v_1}{t_2-t_1}[/tex] for v2
Multiplying both sides by (t2-t1)
[tex](t_2-t_1)a_{ave} = \frac{v_2-v_1}{t_2-t_1}(t_2-t_1)\\(t_2-t_1)a_{ave} = v_2-v_1[/tex]
Adding v1 on both sides
[tex](t_2-t_1)a_{ave}+v_1 = v_2-v_1+v_1\\(t_2-t_1)a_{ave}+v_1 = v_2[/tex]
Hence,
Solving [tex]v = \frac{4}{3}\pi r^3[/tex] for r gives us: [tex]r=\sqrt[3]{\frac{3v}{4\pi}}[/tex]
Solving [tex]a_{ave} = \frac{v_2-v_1}{t_2-t_1}[/tex] for v2 gives us: [tex]v_2 = (t_2-t_1)a_{ave}+v_1[/tex]
