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.

A 20-foot ladder is placed 12 feet from the wall. How high up the wall will the ladder reach?

valina [46]

Use the Pythagorean theorem

the hypotenuse is the ladder which is 20 ft and the base is 12 ft thus 

a^2 + b^2 = c^2 

a^2 + 144 = 400 
a^2 = 256 
a = 16 

so its 16 ft

Perform the following:-1/3 + 6/715/16 - 3/47/6x + -4/3y

Wittaler [7]

SOLUTION

$\begin{gathered} a\text{. }\frac{-1}{3}\text{ + }\frac{6}{7} \\ \\ \frac{-7+18}{21} \\ \\ \frac{11}{21} \end{gathered}$

$\begin{gathered} \frac{15}{16}-\frac{3}{4} \\ \\ \frac{15-12}{16} \\ \\ \frac{3}{16} \end{gathered}$

$\begin{gathered} \frac{7}{6x}+\frac{-4}{3y} \\ \\ \frac{7y-8x}{6xy} \end{gathered}$

So we just have to find the LCM of the denominators, then we perform the rule of addition of fraction

I need someone to explain this step by step. I have a test very soon.

Answer:

So you are going to multiply what is in the parentheses by two it will become 6x + 4.This will be for the second statement box. And the next will be 6x=18 and that will be the subtraction property or equality. For the last it would be x=3 and that would be the division property of equality.
