Show the product -2• (-5) on the number line. Explain how you found your answer
Answers
Answer:
it would be difficult (or at least somewhat confusing) to try to diagram out this question with a drawing on a number line....
the concept here is that the -5, and -2 are NOT "subtracting" but "opposites"
so on a number line you can start at "-5" and draw an arrow to 5 and do the same for "-2"
then show the multiplication as a series of additions (5 2's added together)

A store advertises “buy one, get one half-off" for a new pair of figure skates. If the skates originally cost
$88, how much would you pay for 10 pairs
Answers
A store advertises,
"Buy one and get one half off"
Which means if we buy one, half the price of one will be discounted.
In other words "50% discount on each item we buy"
We will $440 for 10 skates.
Original cost of skates = $88
After 50% discount price of one skate = $88 - $44 = $44
Cost of 10 pairs of skates = 44 × 10
= $440
Therefore, we will pay $440 for 10 skates.

Find the number of pens they need to sell to break even (when R = C).
Answers
Answer:
R=10x
C=2x+7000
P=R-C
a)
Substitute R and C into the equation for P:
P=10x - (2x+7000)
Now substitute 1000 for x and solve for P which is the company's profit if they sell 1000 pens.
b)
Set R equal to C
R=C
Plug in R=10x and C=2x+7000
10x=2x+7000
Solve for x which will be the amount of pens required to be sold to break even.

Answers
9514 1404 393
Answer:
2 : 5
Step-by-step explanation:
You know an hour is 60 minutes, so 1 hour 40 minutes is 60+40 = 100 minutes. Then the ratio is ...
40 min : 1 h 40 min = 40 min : 100 min = 40 : 100 = 2 : 5
(a common factor of 20 can be removed from 40 and 100)
Answer:
2 : 5
Step-by-step explanation:
We require the time to be in the same units
1 hour 40 minutes = 60 + 40 = 100 minutes , then
40 min : 100 min ( divide both parts by 20 min )
= 2 : 5

The cost of 10 pencils is Rs.15 more than the cost of such 7 pencils. What is the cost of a pencil ?
Answers
Let the cost of 7 pencils be 'x' & the cost of 10 pencils be (7x + 15)/10
According to the Question,
⇒(7x + 15)/10 = x
⇒7x + 15 = x × 10
⇒7x + 15 = 10x
⇒7x - 10x = 15
⇒3x = 15
⇒x = 15/3
⇒x = 5

if 9th term ofap is 99 and 99th term is 9 which term is zero
]
Answers
Answer:
108 th term is zero
Step-by-step explanation:
The nth term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₉ = 99 and a₉₉ = 9 then
a₁ + 8d = 99 → (1)
a₁ + 98d = 9 → (2)
Subtract (1) from (2) term by term to eliminate a₁
0 + 90d = - 90
90d = - 90 ( divide both sides by 90 )
d = - 1
Substitute d = - 1 into (1) for value of a₁
a₁ + 8(- 1) = 99
a₁ - 8 = 99 ( add 8 to both sides )
a₁ = 107
Then
107 - (n - 1) = 0
107 - n + 1 = 0
- n + 108 = 0 ( subtract 108 from both sides )
- n = - 108 ( multiply both sides by - 1 )
n = 108
The 108th term is zero
