Hello there.

Question: <span>Rory bought seven 3-packs of golf balls and five 20-pack of golf tees. How many golf items did he buy in all? 

Answer: First you multiply the number of items in the pack by the number of packs bought.
7 x 3 = 21
5 x 20 = 100.
Add together the amount of items.
100 + 21 = 121.

In short, Your answer is Rory bought 121 golf items in total.

Hope This Helps You!

The length and width of a rectangle are ( 2x -5) and ( 3 x +4) What is the Perimeter?
Stella [2.4K]

Answer:

\fbox{ \sf{Perimeter \: of \: a \: rectangle = 10x - 2}}

Step-by-step explanation:

\star{ \sf{ \:  \: Length \: of \: a \: rectangle ( l )  = (2x - 5) }}

\star{ \sf{ \: Width \: of \:  a \: rectangle ( w ) = (3x + 4)}}

\star{ \sf{ \:  \: Perimeter \: of \: a \: rectangle =  ?}}

\boxed{ \bold{  \sf{Perimeter \: of \: a \: rectangle = 2(l + w)}}}

\hookrightarrow{ \sf{Perimeter \: of \: a \: rectangle = 2(2x - 5 + 3x + 4)}}

\text{Step \: 1 : \: Collect \: like \: term}

\text{Like \: terms \: are \: those \: which \: have \: the \: same \: base}

\hookrightarrow{ \sf{2(2x  + 3x - 5 + 4)}}

\hookrightarrow{ \sf{2(5x - 5 + 4)}}

\text{Step \: 2  \: :  \: Subtract \: 4 \: from \: 5}

\text{Remember !\:  : the \: negative \: and \: positive \: integers \: are \: always \: subtracted \: but \: posses \: the \: sign \: of \: the \: bigger \: integer}

\hookrightarrow{ \sf{2(5x - 1)}}

\text{Step \: 3 \:  :  \: Distribute \: 2 \: through \: the \: parentheses}

\hookrightarrow{ \sf{2 \times 5x - 2 \times 1}}

\hookrightarrow{ \sf{10x - 2}}

\sf{∴ \: The \: perimeter \: of \: a \: rectangle = 10x - 2}

\text{Hope \: I \: helped !}

\text{Best \: regards ! }

HELP PLEASEE!!! ASAP
Slav-nsk [51]

Answer:

Hollow-circle rightward-facing arrow with start point number 1.

Step-by-step explanation:

x/8 > 2/(3 + 2^2 + 1) * 2

Multiply both sides by 2:

x/4 > 2/(3 + 2^2 + 1)

Resolve bracket:

x/4 > 2/(3 + 4 + 1)

x/4 > 2/8

x/4 > 1/4

Multiply both sides by 4:

x > 1

To graph this on the number line, you must draw an arrow facing to the right starting from the number 1. It is important that the circle with the arrow is hollow - this is because a hollow circles means more/less than, whereas a filled circled means more/less than or equal to, and this inequality is only more than, not more than or equal to.
