A school purchases calculators from a store for six dollars each. Create an equation that represents the total cost, use d for dollars, and c for the number of calculators purchased.

These both rates are not proportional because if 8 mile in 10 minutes and 20 miles in 30 minutes .. So 10 times 3 equals 30 minutes but if we multiply 8 times 3 is equal to 24. So there are not proportional.. I hope this helped

Answer:

96 degrees

Step-by-step explanation:

180 - 84 = 96    

96 + 84 = 180

We know that each large tree costs $4.50, and each small tree costs $2.25. If you buy 4 large trees, that means you will spend 4 * $4.50 = $<<4*4.5=18>>18 on large trees.

If you can spend a total of $50, then you have $50 - $18 = $<<50-18=32>>32 to spend on small trees.

The total cost of the small trees will be s * $2.25, where s is the number of small trees you buy.

To find the maximum number of small trees you can buy, we can set this expression equal to $32 and solve for s:

s * $2.25 = $32

s = $32 / $2.25

s = 14.22

Since you can't buy a fraction of a tree, the maximum number of small trees you can buy is 14.

Answer:

If each large tree costs 4.50 and you need to buy 4, then 4 x 4.50 = $18.00 leaving you with $32.00. With these 32 dollars left, you can now buy 14 small trees, still being left with a remainder of 0.50$.

Answer:

The first answer choice is the correct one.

Step-by-step explanation:

Going from (1, 4) and ending up at (-2, 2), we see that the original point is now 3 units to the left of its starting position, and 2 units down.

Clarification:  from x = 1 to x = -2 is 3 units (to the left), and

                       from y = 4 to y = 2 is 2 units (down)

The first answer choice is the correct one.

Answer:

\(a= - 3 \\ b = 6\)

Answer:

a=-3, b=6

Step-by-step explanation:

1) First, take a=1/2b-6 and plug it into 2a+3b=12

2(1/2b-6)+3b=12

2) Multiply out the 2

b-12+3b=12

3) Combine like terms

4b-12=12

4) Isolate b by adding 12 to the other side

4b=24

5) Divide by 4 so b doesn't have a variable in front

b=6

To solve for a:

You know that b=6, and a=1/2b-6 so you can plug in b to solve for a

a=1/2(6)-6

Solve the equation to get a

a=3-6

a=-3

  B:) 1 11/16 cups of strawberries and 4 lemons

Step-by-step explanation:

You want to know how many cups of strawberries and how many lemons Mandissa uses in her lemonade if she uses 2 1/4 times 3/4 cups of strawberries, and 2/3 times 6 lemons.

Mandissa's recipe has strawberries in the amount of ...

   (2 1/4) × (3/4 cup) = (9/4)(3/4) cups = 27/16 cups = 1 11/16 cups

Mandissa's recipe has lemons in the amount of ...

  (2/3) × (6 lemons) = (2/3)(6) lemons = 4 lemons

Mandissa uses 1 11/16 cups of strawberries, and 4 lemons, matching choice B.

Answer:

The solution is ([4], [19]).

Step-by-step explanation:

To solve the system of equations using the substitution method, we can follow these steps:Step 1: Start with the given equations:

y = 4x + 3 (Equation 1)

y = 7 + 3x (Equation 2)Step 2: Choose one of the equations and solve for one of the variables in terms of the other variable. Let's choose Equation 1 and solve for y in terms of x:

y = 4x + 3Step 3: Substitute the expression for y from Equation 1 into Equation 2 and solve for x:

4x + 3 = 7 + 3x (Substituting y = 4x + 3 from Equation 1)

4x - 3x = 7 - 3

x = 4Step 4: Substitute the value of x found in Step 3 back into either Equation 1 or Equation 2 to solve for y. Let's use Equation 1:

y = 4(4) + 3 (Substituting x = 4)

y = 19So the solution to the system of equations is x = 4 and y = 19. Therefore, the solution is ([4], [19]).

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

2. x + 98 + 50 = 180

3. x = 32°

Step-by-step explanation:

hey there,

< 2. We know that there are 180 degrees in every triangle, and every triangle has only 3 angles. So when you add up those 3 angles, it will ALWAYS equal 180! And since we do not know one of the angles, we will just put the value of that angle as "x" into the equation.

3. Here, you should be able to find x! x = (180-(98+50)) = 32

The final answer is 32 degrees. >

Answer:

Ribeye (ea) = $18.54

Salmon (ea) = $9.78

Step-by-step explanation:

x is the price for each ribeye steak

y is the price for each grilled salmon

15x + 28y  = $551.97 (a)

24x + 14y = $581.91 (b) -----(x2)------> 48x + 28y = 1163.82 (c)

Subtract c with a

48x + 28y = 1163.82 (c)

15x + 28y  = $551.97 (a)

===================  -

33x           = 611.85

x = 18.54

Put the value of x into a

15 · 18.54 + 28y = 551.97

278.1 +28y = 551.97

28y = 273.87

y = 9.78

In conclusion, the price of 1 ribeye is $18.54, and the price of 1 salmon is $9.78.

Step-by-step explanation:

Step-by-step explanation:

Jeff spends $2.52 per gallon and buys 14 gallons, so his total expenditure is:

Total spent by Jeff = $2.52/gallon * 14 gallons = $35.28

Anna spends $2.16 per gallon and buys 15 gallons, so her total expenditure is:

Total spent by Anna = $2.16/gallon * 15 gallons = $32.40

To find the difference in their expenditures, we subtract Anna's total from Jeff's total:

Difference = Total spent by Jeff - Total spent by Anna

Difference = $35.28 - $32.40 = $2.88

Therefore, Jeff spends $2.88 more than Anna on gas.
