Morty spent $54 on tulips and roses and bought a total of 14 flowers. If tulips cost $5 and roses $3
Tom [10]

Answer:

a) Let's define the variables:

t = number of tulips bought

r = number of roses bought

We know that each tulip costs $5, and each rose costs $3.

Then the total cost will be:

$5*t + $3*r

We know that Morty spent a total of $54, then we have the equation:

$5*t + $3*r = $54

We also know that he bought a total of 14 flowers, then:

r + t = 14

Then the system of equations is:

$5*t + $3*r = $54

r + t = 14

b) To solve the system, first, we need to isolate one of the variables in one of the equations. I will isolate r in the second one:

r = 14 - t

Now we can replace this into the other equation:

$5*t + $3*r = $54

$5*t + $3*(14 - t) = $54

Now we can solve this for t.

$5*t + $3*14 - $3*t = $54

$2*t + $42 = $54

$2*t = $54 - $42 = $12

t = $12/$2 = 6

t = 6

He bought 6 tulips.

Now we can use the equation r = 14 - t

r = 14 - 6 = 8

r = 8

He bought 8 roses.

12. The circumference of a quarter is about 76 mm. What is
77julia77 [94]

Answer: A= 460 mm2

Step-by-step explanation:

Hi, since the circumference formula is :

C = 2 π r

Where r is the radius, we can solve the formula for the radius replacing with the value given:

76 =2 π r

76 / (2 π) = r

r = 12.1 mm

Now , we have to apply the formula for the area of a circle.

A = π r^2

A = π (12.1)^2

A= 459.96 mm2= 460 mm2 (rounded to the nearest tenth, since .9 is higher than .5)

Feel free to ask for more if needed or if you did not understand something.
