Solve the equation 3(x+4.5x ) = 36. Explain your reasoning THOROUGHLY.

Vesna [10]

Answer:

$x \approx 2.18$

Step-by-step explanation:

$3(x+4.5x)=36$

we can use the distributive property and get

$3(x)+3(4.5x)=36\\\\3x+13.5x=36\\\\$

and we can add like terms

$(3+13.5)x=36\\\\16.5x=36$

and know we divide both sides by 16.5

$16.5x*(\frac{1}{16.5})=36*(\frac{1}{16.5})\\\\x=\frac{36}{16.5}$

and doing the dvision we get that

$x\approx 2.18$

I WILL GIVE BRAINLIEST TO WHOEVER ANSWERS FIRST!!!

Alex Ar [27]

Step-by-step explanation:

You want to set one of the equations equal to either x or y. For this, I put x+y=-2 equal to y which would be y=-x-2. Then you plug this in to the other equation for y. This would give you 5x+2(-x-2)=2. When you factor the two into the parenthesis, combine like terms, and keep the x values on ones side and the other numbers on the other side, you get 3x=6

Find the volume of each figure

pshichka [43]

Answer:

See explanation

Step-by-step explanation:

1. The first figure shows triangular prism. The volume of the triangular prism is

$V=\text{Base area}\times \text{Height}$

The base of this triangular prism is the triangle with the base of 7 cm and height of $h$ cm (it is not seen).

The base area is

$\text{Base area}=\dfrac{1}{2}\times \text{Base}\times \text{Height}=\dfrac{1}{2}\times 7\times h=\dfrac{7h}{2}\ cm^2$

and the volume of the prism is

$V=\dfrac{7h}{2}\times 13=\dfrac{91h}{2}\ cm^3$

Just substitute the length of the height and calculate the volume.

2. The second figure shows square pyramid. The volume of the square pyramid is

$V=\dfrac{1}{3}\times \text{Base area}\times \text{Height}$

The base of this square pyramid is the square with the side length of 4 yd.

The base area is

$\text{Base area}= \text{Side Lenght}^2=4^2 =16\ yd^2$

and the volume of the pyramid is

$V=\dfrac{1}{3}\times 16\times 12=64\ yd^3$

Bobby decides to sell lemonade on a hot summer day. If Bobby sells 20 glasses of lemonade for $0.20 per cup, and his average tot

borishaifa [10]

Answer:

Bobby's economic profits for the day is $0.60.

Step-by-step explanation:

Bobby sells 20 glasses of lemonade for $0.20 per cup.

Amount earned = $20\times0.20=4$ dollars

The average total cost is $0.17.

So, difference in selling amount and average = $0.20-0.17=0.03$ dollars

Therefore, Bobby's economic profits for the day is = $20\times0.03=0.60$ dollars

Hence, the answer is $0.60.
