The given diagram is a trapezium. We know that the consective sides of a trapezium are equal. so,

Putting the values of consecutive sides equal:

So, KI will be equal to LI

3x-7 = x+3

$3x-7-x=x+3-x\\2x-7=3\\2x-7+7=3+7\\2x=10\\x=5$

Putting the value of x in the equation of KI

3x-7

=3(5)-7

=15-7

Hence, the correct answer is D. 8 ..

Natalie had 64 beads. She used 24 beads to make a bracelet. She used 7/8 of the remaining beads to make a necklace. How many bea

Eddi Din [679]

Answer:

Natalie have left with 5 beads.

Step-by-step explanation:

Given:

Natalie had 64 beads. She used 24 beads to make a bracelet. She used 7/8 of the remaining beads to make a necklace.

Now, to find the beads does Natalie have left.

Total beads Natalie had = 64 beads.

And beads she used to make a bracelet = 24 beads.

So, the remaining beads are = $64-24=40\ beads.$

Now, the beads she used to make a necklace = $40 of \frac{7}{8}$

= $40\times \frac{7}{8}$

= $\frac{280}{8}$

= $35\ beads$

Hence, the beads Natalie have left = remaining beads - beads used to make necklace.

$The\ beads\ Natalie\ have\ left\ =\ 40-35$

$The\ beads\ Natalie\ have\ left\ =\ 5\ beads.$

Therefore, Natalie have left with 5 beads.
