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
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

Answer:
3). -5. 4).7.
Step-by-step explanation:
3).CB + BA = CA
(x+15) + (x+13) = 18
2x + 28 = 18
2x = 18 - 28
2x = -10
x = -5.
4). ED + DC = EC
(2x - 7) + (x - 6) = 8
3x - 13 = 8
3x = 8 + 13
3x = 21
x = 7.
PART 1!! There’s more to it so please help me!! lesson 3.3.4 Practice: modeling: graphs of functions!
Answer:
the first cell next to 3 (time hours x) is 300
the point is (3, 300)
the second cell is 1000
the point is (10,1000)
the values for the second table should be the same if they have the same unit rate which is 100 watts per hour
Step-by-step explanation:
If there is 100 watts perhour just multiply the number of hours by this unit
Write your own math poem. The content of your poem should reflect what you know about the properties of integer exponents or scientific notation. Challenge yourself by playing with the poem’s form—use a fun rhythm, use a pattern of syllables, or make it rhyme!
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!

Step-by-step explanation:
1/5 (x + 3/5)- 4/5 = 5
Answer:
1/5 (x + 3/5)- 4/5 = 5
1/5x + 3/25 - 4/5 = 5
(5x + 3 -20)/25 = 5
5x - 17 = 125
x = 142/5

Solve for r:
[tex]v = \frac{4}{3}{r}^{3} [/tex]
Solve for v2
[tex]a \: ave = \frac{v2 - v1}{t2 - t1} [/tex]
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]

x − 2y = 15
2x + 4y = -18
Answer:
y=-6 ; x=3
Step-by-step explanation:
x − 2y = 15
2x + 4y = -18
x − 2y = 15
+2y . +2y
x=2y+15
2(2y+15) + 4y = -18
4y+30+4y=-18
8y+30=-18
-30 . -30
8y=-48
y=-6
x=2(-6)+15
x=-12+15

It costs $95 to rent the gym for a banquet hall. It costs $4 for each student that attends the dance. The student council has a budget of $311. If the student council pays for the dance from its budget, how many students can go to the dance? **GIVE EXPLANATION**
Answer: 43 max
Step-by-step explanation:
Base cost: 95
311-95 = $216 to pay for students who attend
216/5 = 43.2, but 0.2 of a student can't go. So at most 43 students can go to the dance.

What is the slope of the line?
Answer:
3/1
Step-by-step explanation:
Answer:
[tex]\frac{3}{1}[/tex]
Step-by-step explanation:
If you start at (2,0) you go up 3 and to the right 1. The reason for this is because you need to find points that intersect perfectly to find the slope. I really hope this makes sense. Im not sure how else to explain it. Have a good day :)
