{33, 39}
Answers
The set {126, 168, 189} has 21 as a common factor.
The set{154, 231} has 11 as a common factor.
Common factor:If a number m is completely divisible by number n. Then number n will be the one factor of number m.
(a). Given set of number is, {126, 168, 189}
Now check, 21 is a common factor or not.
[tex]\frac{126}{21}=6,\frac{168}{21}=8,\frac{189}{21}=9[/tex]
It is observed that all numbers are completely divisible by 21.
So that , 21 is common factor.
(b). Given set of number is, {154, 231}
[tex]\frac{154}{11}=14,\frac{231}{11}=21[/tex]
It is observed that all numbers are completely divisible by 11.

Dimitri wrote the equations y = 3x and y = x + 3.
Use the drop-down menus to make true statements about the equations and the graph.
Answers
The coordinate point of intersection on the graph will be at (1.5, 4.5)
Given the equations Dimitri wrote expressd as:
y = 3x
y = x + 3
Since they are both y-values, we can equate the right hand side to have:
3x = x + 3
3x - x = 3
2x = 3
x = 3/2
x = 1.5
Get the value of y:
y = 3x
y = 3(1.5
y = 4.5
Hence the coordinate point of intersection on the graph will be at (1.5, 4.5)

_________________________ 6Harry is planning a holiday for 4 people for 7 days. Here are the costs for the holiday for each person. Travel£150 Hotel£50 for each day Spending money£250 Work out the total cost of the holiday for 4 people for 7 days.
Answers
Answer: $3,000
Step-by-step explanation:
The cost for a single person is:
Travel £150
Hotel £50 for each day
Spending money £250
Hotel is the only one that changes per the number of days so the total cost for a single person for 7 days is:
= 150 + (50 * 7) + 250
= 150 + 350 + 250
= $750
There are 4 people so the total cost will be:
= 750 * 4 people
= $3,000

The bases of a trapezoid have lengths 10 and 18. If the height of the trapezoid is 6, what is the area of the trapezoid
Answers
Answer:
84
Step-by-step explanation:
The bases of a trapezoid have lengths 10 and 18. If the height of the trapezoid is 6, what is the area of the trapezoid
The area of a trapezoid is given as:
1/2(b1 + b) × h
Where:
b1 = Base 1 = 10
b2= Base 2 = 18
h = Height = 6
Therefore, the area of a trapezoid =
1/2 (10 + 18) × 6
= 28/2 × 6
= 84
Therefore, the area of the trapezoid = 84

A line is represented by the equation y = 3x - 6. Which is a coordinate of a
point that lies on the line?
0 (0,3)
0 (-6,3)
O (2,0)
0 (-3,1)
Answers
Answer:
(2,0)
Step-by-step explanation:
Simply plug in the coordinates. y= 3x - 6, so in this case 0= 3(2) - 6 or 0=0, making the point on the line. If the equation is not true like when using (0,3) and getting 3= -6, then the point is not on the line.
They are 20 blocks per mile in tara's city. Tara's walks 13 blocks. Her fitness tracker say he walk 0.71 mile. Show if her fitness tracker is accurate.
Answers
Answer:
Step-by-step explanation:
13 blocks × (1 mile)/(20 blocks) = 13/20 mile = 0.65 mile
Tracker is inaccurate
The fitness tracker is inaccurate.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, there are 20 blocks per mile.
20 blocks = 1 mile
1 block = (1/20) mile
13 block = (13/20) mile
13 block = 0.65 mile
Therefore, Tara walks 0.65 miles, not 0.71 miles.
Hence, the fitness tracker is inaccurate.
