Hello!

Find the cost of each individual item.

Each roll of tape costs $0.64.

0.87 / 3 = 0.29

Each notebook costs $0.29.

Each highlighter costs $1.59.

1.98 / 2 = 0.99

Each pen costs $0.99.

One roll of tape is $0.64, two notepads are $0.58 two highlighters cost $3.18, two pens are 1.98.

We have to determine what it costs for one single item and then divide or multiply by the quantity needed.

1 roll Tape= $1.28÷2= $0.64

2 rolls Notepads= 0.87÷3= 0.29x2= $0.58

2 Highlighters= $1.59x2= $3.18

2 Pens= $1.98

Add these totals:
+0.64
+0.58
+3.18
+1.98
=$6.38

ANSWER: B) $6.38

Hope this helps! :)

Two siblings' ages have a sum of 64 years. The older sibling was born 6 years before their young sibling.
Elina [12.6K]

Hi!

So we have to make a system of equations here.

Let sibling 1 be O and sibling 2 be Y (for older and younger)

So:

O + Y = 64

O = 64 - Y

(Either one works)

The older sibling is 6 years older.

O = Y + 6

Make everything in terms of Y.

64 - Y = Y + 6

Same to both:

58 = 2y

2y = 58

Divide by 2 on both sides:

y = 29

Since the older sibling is 6 years older:

29 + 6 = 35

Y = 29

O = 35

Let me know if you have any questions.

Vikentia [17]
Use the communicative property of addition to switch to order and you get
13 - 5, so the answer is 8, or k = 8

OR

-5 + 13 = k
Combine like terms
8 = k
or
k = 8<span />
