Vusi makes bead bracelets in different designs. The first design uses 23 beads, the second design uses 29 beads and the third de

sergey [27]

When the remainder theorem is applied to the total number of beads, the number of beads left is 3

<h3>What is remainder theorem?</h3>

The question is an illustration of remainder theorem. Remainder theorem is used to determine the remainder when a number divides another

The number of beads used in each design are given as:

$First = 23$

$Second = 29$

$Third = 31$

Calculate the total number of beads used for all three designs

$Total =First + Second + Third$

$Total =23 + 29 + 31$

$Total =83$

The number of available beads is:

$Available = 750$

Divide 750 by 83, to get the total number of designs

$n = \frac{750}{83}$

$n =9.03$

Remove decimal (do not approximate)

$n = 9$

The number of beads remaining is calculated using:

$Remaining =Available -n \times Total$

$Remaining =750 -9 \times 83$

$Remaining =3$

Hence, there are 3 beads remaining

8+35/w=15<br>a.8<br>b.6<br>c.10<br>d.5

RoseWind [281]

Answer:

$\boxed{ \bold{ \huge{ \bold{w = 5}}}}$

Option D is the correct option

Step-by-step explanation:

$\sf{8 + \frac{35}{w} = 15}$

⇒ $\sf{ \frac{8 \times w + 35}{w} = 15}$ { w ÷ 1 = w , So, I wrote 8 × w }

⇒ $\sf{ \frac{8w + 35}{w} = 15}$

Apply cross product property

⇒ $\sf{8w + 35 = 15w}$

Move 15w to left hand side and change it's sign

Similarly, Move 35 to right hand side and change it's sign

⇒ $\sf{8w - 15w = - 35}$

Collect like terms

⇒ $\sf{ - 7 w = - 35 }$

Divide both sides of the equation by -7

⇒ $\sf{ \frac{ - 7w}{ - 7} = \frac{ - 35}{ - 7} }$

Calculate

⇒ $\sf{w = 5}$

Hope I helped!

Best regards!!
