Answer:

$\huge{ \fbox{ \sf{ - 2y - 30}}}$

Step-by-step explanation:

$\star{ \sf{ \: (4y - 10) - (6y + 20)}}$

$\text{Step \: 1 }\: : \sf{While \: subtracting \: sign \: of \: each \: term \: of \: the \: second \: expression \: changes}$

$\hookrightarrow{ \sf{4y - 10 - 6y - 20}}$

$\text{Step \: 2 \: : \sf Collect \: like \: terms}$

$\sf{Like \: terms \: are \: those \: which \: have \: the \: same \: base.}$

$\hookrightarrow{ \sf{4y - 6y - 10 - 20}}$

$\hookrightarrow{ \sf{ - 2y - 10 - 20}}$

$\text{Step \: 3 \: : \sf{Calculate}}$

$\underline{ \text{Remember!}} : \sf{The \: negative \: integers \: are \:always \: added \: but \: posses \: the \: negative \: ( - ) \: sign.}$

$\hookrightarrow{ \sf{ - 2y - 30}}$

Hope I helped!

Best regards! :D

Jill and Marcy go to an ice cream store where they have the option of getting a smoothie in either a cylindrical or rectangular

k0ka [10]

Answer: Jill got the larger smoothie and its volume is 1609.14 cubic cm.

Step-by-step explanation:

Since we have given that

Jill purchased the cylindrical container.

Height of container = 8 cm

Radius = 8 cm

So, volume of cylindrical container would be

$\pi r^2h\\\\=\dfrac{22}{7}\times 8\times 8\times 8\\\\=1609.14\ cm^3$

Marcy purchased the rectangular container.

Height of container = 8 cm

Width = 8 cm

Length = 8 cm

so, volume of rectangular container would be

$l\times b\times h\\\\=8\times 8\times 8\\\\=512\ cm^3$

Hence, Jill got the larger smoothie and its volume is 1609.14 cubic cm.
