. The student's conclusion is incorrect because the solution to the system of equations 4x + 2y = 32 and 5x + 2y = 36 is (4, 8).
B is right option
4x + 2y = 32
5x + 2y = 36 subtracting
-x=-4
x=4
4(4)+2y=32
16+2y=32
2y=16
y=8
hope this helps
Answer:
<h2>Let the common ratio b x thus the part becomes</h2><h2>=5x and 4x respectively</h2>
<h2>Thus,ATQ</h2>
<h2>5x+4x= 54</h2>
<h2>9x=54</h2>
<h2>x= 6</h2>
<h2>Sam will get is £30 (putting the value of x)</h2><h2>and Bethan will get £24</h2>
Answer:
i. 6
ii. 
iii. 7
Step-by-step explanation:
First organize the data from least to greatest. 3,3,4,5,6,7,7,7,8
To find the median, remove the extremes from the data over and over.
3,4,5,6,7,7,7
4,5,6,7,7
5,6,7
6
To find the mean, add all of the numbers and divide by 9
3+3+4+5+6+7+7+7+8=50
50/9=
To find the modal mark, simply find the number present most in the data set: 7(occurs 3 times)
Hope it helps <3
Largest integer: 57
x + x + 1 + x + 2 = 168
3x + 3 = 168
-3 -3
3x = 165
/3 /3
x = 55
x = smallest integer = 55
x + 1 = middle integer = 55 + 1 = 56
x + 2 = largest integer = 55 + 2 = 57
U first find the common denominator which is 8
Then subtract to get 7/8
