Answer:

Number of basketball = 9

Number of football = 15


Step-by-step explanation:

let number of basketball = x

let number of football = y


Given that cost of 1 basketball = 22

Then cost of x basketball = 22x


Given that cost of 1 football = 30

Then cost of x football = 30y


Then total expense = 22x+30y

Given total expense is $648 so we can set both equal to each other and get:

22x+30y=648...(i)


Given that they bought 6 more footballs than basketballs

so we get:

y=6+x...(ii)


Now plug (ii) into (i)

22x+30y=648

22x+30(6+x)=648

22x+180+30x=648

52x+180=648

52x=648-180

52x=468

x=9

plug x=9 into (ii)

y=6+x=6+9=15

Hence final answer is :

Number of basketball = 9

Number of football = 15

Bob and Carol are making glass dolls. On average, they break 12% of the dolls. Today, they only broke 2/3 as many dolls as usual
konstantin123 [22]
If you would like to know how many dolls did Bob and Carol break today, you can calculate this using the following steps:

On average, they break: 12% of 175 = 12/100 * 175 = 21 dolls.
Today: 2/3 as many dolls as usual = 2/3 * 21 = 14 dolls

Result: Bob and Carol broke 14 dolls today.

N
ZanzabumX [31]

Answer:

x = 4 is the solution

Step-by-step explanation:

given  = x ( square both sides )

x + 12 = x² ( rearrange into standard form )

x² - x - 12 = 0 ← in standard form

(x - 4 )(x + 3 ) = 0 ← in factored form

equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 3 = 0 ⇒ x = - 3

Insert these values into the original equation, and if both sides are equal, and those are the solutions.

x = 4 :  =  = 4 = x ← correct

x = - 3 :  =  = 3 ≠ - 3 ← false

the answer is x = 4

Make n the subject of the formula
kogti [31]

Answer:

\mathsf{ \frac{m + 21}{5} = n }

Step-by-step explanation:

To make "n" the subject of the formula, rearrange the formula so it begins with " n = "

To isolate the variable "n", you need to inverse the other terms on that side of the equation where "n" really is.

=> m = 5n - 21

  • <em>there's</em><em> </em><em>a</em><em> </em><em>"</em><em>-21</em><em>"</em><em> </em><em>next</em><em> </em><em>to</em><em> </em><em>"</em><em>5n</em><em>"</em><em>,</em><em> </em><em>inverse</em><em> </em><em>of</em><em> </em><em>subtraction</em><em> </em><em>is</em><em> </em><em>addition</em><em>,</em><em> </em><em>so</em><em> </em><em>add</em><em> </em><em>21</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>equation</em><em>.</em><em> </em>

=> m + 21 = 5n <u>-</u> <u>21</u> + <u>21</u>

=> m+ 21 = 5n

  • <em>There's</em><em> </em><em>also</em><em> </em><em>a</em><em> </em><em>5</em><em> </em><em>attached</em><em> </em><em>to</em><em> </em><em>n</em><em>,</em><em> </em><em>that</em><em> </em><em>means</em><em> </em><em>the</em><em> </em><em>multiplication</em><em> </em><em>of</em><em> </em><em>n</em><em> </em><em>with</em><em> </em><em>5</em><em>,</em><em> </em><em>the</em><em> </em><em>inverse</em><em> </em><em>of</em><em> </em><em>multiplication</em><em> </em><em>is</em><em> </em><em>division</em><em>,</em><em> </em><em>so</em><em> </em><em>dividing</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>equation</em><em> </em><em>by</em><em> </em><em>5</em>

<em>\mathsf{ \frac{m + 21}{5} = n }</em>
