Tom’s first mistake was made in step___

1 answer:

lapo4ka [179]3 years ago

4 0

Answer:

OPTION F

OPTION D

Step-by-step explanation:

Tom made his first mistake in Step 4, by subtracting 2.

After Step 3, he should have added 2 on both sides i.e.,

x = 4y - 2 should have become x + 2 = 4y - 2 + 2

⇒ x + 2 = 4y

So, in order to correct his mistake, he should add 2 on both the sides of the equation.

Denise bought a box of 560 pieces of candy.4/5 of the pieces of the candy were fruity and 1/4 of the remaining pieces of candy w

Liula [17]

Answer:

<em>Number of Other flavor candy is 84.</em>

Step-by-step explanation:

Given that

A total of 560 pieces of candy are there in the box.

$\frac{4}{5}$ of the pieces are fruity.

Number of Fruity pieces:

$\dfrac{4}{5} \times 560\\\Rightarrow 4 \times 112 =448$

Now, remaining pieces = Total pieces - Fruity pieces

remaining pieces = 560 - 448 = 112

Also given that $\frac{1}4$ of the remaining pieces are mind.

Number of mint pieces:

$\dfrac{1}{4}\times 112 = 28$

Other flavors remaining = Total pieces - Fruity pieces - Mint pieces

Other flavors remaining = 560 - 448 - 28

Other flavors remaining = 112 - 28 = <em>84</em>

<em>Number of Other flavor candy is 84.</em>
