Answer:
7) refer to d=rt triangle so answer is t= d/r
8) rearrange by dividing so it should be PV/nR = T
9) move 5r to other side which become 2p = q - 5r then divide by 2. final answer is p = q-5r/2
10) multiply both side by b/1 so b got cancel on left side
right side become c(b/1) which is same as cb
then you divide both side by c to isolate b on the right side
final answer is a/c=b
Answer:
Step-by-step explanation:Write as two points in terms of: (number of people, cost in $)
�
(15,120) and (25,200)
�
Find the equation of the line using:
�
m = (y2 – y1) / (x2 – x1) and y = mx + b
�
Equation:
�
Y = 8x
�
plug in x = 40
�
y = 8(40) = 320
�
A party of 40 people will cost $320.00.
�
Slope:
�
m = 8 $/person
�
For every person that attends the party, the caterer’s bill increases by $120.00.
�
y-intercept: 0
�
(0,0)
�
This tells us that if no one attends the party, the caterer’s bill will be $0.00. So the
�
caterer has no base cost they charge to caterer a party.
�
Answer:
(2,5)
Step-by-step explanation:
Choose values for x and substitute in to find the corresponding y values.
(2) - 2y = -8
2 = 2y - 8
10 = 2y
5 = y
(2,5)
The number of sugar cubes in the box is 180
<h3>How to determine the number of sugar cubes?</h3>
The given parameters are:
- Layers = 5
- Pieces = 2 or 3
- Cups of tea = 61 and 88
Multiply 61 and 88 by 2 and 3
61 * 2 = 122
61 * 3 = 183
88 * 2 = 176
88 * 3 = 264
The number of sugar cubes cannot be 122 and 264, because they are out of the range
So, we have:
183 and 176
There are 5 layers.
This means that the number of sugar cubes is divisible by 5.
The only number between 176 and 183 that is divisible by 5 is 180
Hence, the number of sugar cubes is 180
