Camille buys a cake for $\$24.99$ . She also buys $12$ brownies. Each brownie costs the same amount. She spends $\$39.99$ on the cake and the brownies.
Camille finds the cost of each brownie by calculating $(39.99\ -\ 24.99)\ \div\ 12$ . Tanya finds the cost of each brownie by solving the equation $39.99\ +\ 12b\ =\ 24.99$ , where $b$ is the cost of each brownie.
Which approach uses the sequence of operations necessary to find the cost of each brownie: Camille’s, Tanya’s, both, or neither? Explain why.
Respond in the space provided.
Answers
Answer:
Camille's approach
Step-by-step explanation:
Each brownie costs $1.25. Tanya's equation is wrong because the end result is the cost of the cake and in order to get that you would need to subtract instead of adding.

The formula for finding the volume of a rectangular prism is V = Bh. A rectangular prism with dimensions _________ will have a volume of 150 cubic units.
Answers
Answer: 10 * 5 * 3
Step-by-step explanation:
We want to find a base and a height that will multiply together to equal 150 [tex]units^{3}[/tex].
One solution is a [tex]B = 50 units^{3}[/tex] and [tex]h = 3 units^{3}[/tex].
Thus we need a length and width of the base that will multiply together to equal 50 [tex]units^{2}[/tex]. One solution is 10 units * 5 units.
Putting this all together, we have a solution of 10 units * 5 units * 3 units, which will have volume of 150 cubic units.

Pls help me ASAP!!! Tickets for a concert cost $7.50 for students and $15 for adults. 150 ticket are sold, and $1612.50 is collected. How many student tickets were sold? How many adult tickets?
Answers
Let's say the # of students is x and the # of adults is y. The two equations we get are 7.50x + 15y = 1612.50 and x + y = 150
x = 150 - y
7.5(150-y) + 15y = 1612.5
1125-7.5y+15y=1612.5
7.5y=487.5
y=65
x=150-65
x=85

Can someone please help me find the area of the figure.
Answers
Answer:
45.4
Step-by-step explanation:
→ Area of the polygon = Area of Square + Area of semi-circle
Area of square :
→ Area of square = Side × Side
→ Area of square = 6 m × 6 m
→ Area of square = 36 m [tex] \sf ^2[/tex]
Area of semi-circle :
→ Area of semi-circle = [tex] \sf \dfrac{Area \: of \: circle}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{\pi r^2}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{\pi r^2}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{3.14 \times (3)^2}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{3.14 \times 3 \times 3}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{28.26}{2} [/tex]
→ Area of semi-circle = 14.13 m[tex] \sf ^2[/tex]
⇒ Area of shape = ( 36 + 14.13 ) m[tex] \sf ^2[/tex]
⇒ Area of shape = 50.13 m[tex] \sf ^2[/tex]

Area of the shape is 50.13 m[tex] \sf ^2[/tex].Can sum1 answer pls really need help

Answer:
(47xy)/(6√3)
Step-by-step explanation:
A variable term is one that contains one or more variables, possibly with a coefficient. We can use 47xy as our variable term.
A constant is some number, or a representative of a particular number. π and e and Ф are representative of irrational constants. Of course, any number is also a constant. We can use 6√3 as our constant.
A quotient is formed when a first value is divided by a second value.
Here is the quotient of our variable term and our constant:

Lily and Mackenzie collected some stamps. If Lily gave 4 stamps to Mackenzie, Mackenzie would have twice as many stamps as Lily. If Mackenzie gave 4 stamps to Lily, they would have the same number of stamps. How many stamps did each girl have?
GIVING BRAINLIEST. PLS HELP. SHOW UR WORK TOO
Answers
Answer: hope this helps ♡
Lily had 16 stamps and Mackenzie had 20 stamps.
Step-by-step explanation:
Lily gives 4 stamps to Mackenzie
(Mackenzie) m + 4 = 2(L - 4) (Lily)
Solve for Lily:
m + 4 = 2L - 8
m + 4 + 8 = 2L
(m + 12) ÷ 2 = 2L ÷ 2
(m + 12) ÷ 2 = L
L = (m + 12) ÷ 2 (we will substitute this value for L in the second equation)
Mackenzie gives 4 stamps to Lily
(Mackenzie) m - 4 = L + 4 (Lily)
m - 4 = ((m + 12) ÷ 2) + 4
m × 2 - 4 = ((m + 12) ÷ 2 × 2) + 4
2m - 4 + 4 = (m + 12) + 4 + 4
2m - m = (m - m + 12) + 8
m = 12 + 8
m = 20 (we will substitute this value of m in the next equation)
L = (m + 12) ÷ 2
L = (20 + 12) ÷ 2
L = 32 ÷ 2
L = 16
