Answer:
$7.2
Step-by-step explanation:
Mike paid $18 for 5 photos
= 18/5
= 3.6
His sister wants to purchase 2 of the same album
= 2 × 3.6
= 7.2
Hence she will pay $7.2 for the two albums
Answer:
4.) Choice B
&
5.) Choice A
Step-by-step explanation:
<em><u>Question 4:</u></em>
First you have to solve for y to get slope intercept form.
The slope is a fraction but you need it to convert it to a decimal so that'll be Choice B.
<em><u>Question 5:</u></em>
For this one I we will use this formula 
I will choose the easy pairs to plug it in 
The slope is a fraction again but you can convert it and that'll be Choice A.
In the above problem, you want to find the number of multiples of 7 between 30 and 300.
This is an Arithmetic progression where you have n number of terms between 30 and 300 that are multiples of 7. So it is evident that the common difference here is 7.
Arithmetic progression is a sequence of numbers where each new number in the sequence is generated by adding a constant value (in the above case, it is 7) to the preceding number, called the common difference (d)
In the above case, the first number after 30 that is a multiple of 7 is 35
So first number (a) = 35
The last number in the sequence less than 300 that is a multiple of 7 is 294
So, last number (l) = 294
Common difference (d) = 7
The formula to find the number of terms in the sequence (n) is,
n = ((l - a) ÷ d) + 1 = ((294 - 35) ÷ 7) + 1 = (259 ÷ 7) + 1 = 37 + 1 = 38
