C= 8x + 5y
y-number of child tikets
C-8x= 5y
(C-8x)/5 =y
First option from up to down

The first answer should be correct if you used literal equations. You first start off with c = 8x + 5y. To make it easier, if you move the c= to the other side, you'd get 8x + 5y = c. Then, you subtract 8x on both sides leaving you with 5y = c - 8x. Last, you would divide c - 8x by 5, which leaves you with you final answer of y=(c-8x)/5

6(4.4) = 6 x 4.4 = 26.4

The one with the parenthesis would be the distributive property. I'm not 100% sure, though. Hope this helps.

What is the mass of a solid ball of iron with a radius equal to 18 cm if it is known that the density of iron is 7800 kg/m

Shtirlitz [24]

Answer:

60.6528 kg

Step-by-step explanation:

Assuming the solid ball of iron is a sphere with a radius of 18 cm (or 0.18 m), we can compute the volume of the sphere:

$V=\frac{4}{3}\pi r^3\\\\V=\frac{4}{3}\pi (\frac{18}{100})^3\\\\V=\frac{4}{3}\pi (0.005832)\\\\V=0.007776$

Therefore, the volume of the solid ball is 0.007776 m³

Since we know that density is mass/volume, then we can find the mass of the iron:

$\rho=\frac{mass}{volume}\\ \\7800\: kg/m^3=\frac{mass}{0.007776\: m^3}\\\\mass=60.6528\:kg$

Thus, the mass of the solid ball of iron is 60.6528 kg

$[Hello,BrainlyUser!\; I'm\;Lenvy]$

$Your\;Answer\;Is\;Below$

Answer:

42 feet

Step-by-step explanation:

First let know what is

Yards to Feet

Note that;

1 Yard ⇒ 3 Feet

Thus, Formula: Multiply the length value by 3

Given:

Lena bought 14 yards of ribbon. How many feet of ribbon did she buy?

Therefore, 14 * 3 = 42

Hence, Answer is Lena brough 42 feet of ribbon.
