Answer:
n = 3.5
Step-by-step explanation:
basically it's saying that 2.8 is proportional to 4.8 as n is proportional to 6. therefore:
2.8/4.8 = n/6
0.583 = n/6
3.5 = n
Four boys weighed themselves in different pairs and alone. The weights of the pairs were 110 kg, 112 kg, 113 kg, 118 kg, 121 kg, and the weight of one pair was lost. The total weight of the four boys was 230 kg. What was the lost weight?
The lost pair of weight can be found by subtracting the a known pair from
the total weight leaving the value of the lost pair.
The lost weight of a pair of boys is 120 kg
Reasons:
Let a, b, c, and d represent the weights of the four boys, we have;
The number of ways of selecting pairs (two boys) of boys from a group of
four is given using combination formula as follows;
[tex]_nC_r = \dfrac{n!}{r! \cdot (n - r)!}[/tex]
Which gives;
[tex]_4C_2 = \dfrac{4!}{2! \cdot (4 - 2)!} = 6[/tex]
₄C₂ = 6
Therefore, the weights of the pairs are;
a + b = 110
a + c = 112
a + d = 113
b + c = 118
b + d = 121
c + d = Lost weight
c + d = Lost weighta + b + c + d = 230 (given)
Therefore;
The lost weight, c + d = 230 - (a + b)
Which gives;
c + d = 230 - (110) = 120
The lost weight = c + d = 120
The lost weight = 120 kgLearn more here:

Answer:
116
Step-by-step explanation:
you can use variables
a+b=110
a+c=112
a+d=113
b+c=118
b+d=121
add up the weights and you get 574 kg (you need to find c+d)
3a+3b+2c+2d=574
a+b+c+d = 230 as given then you multiply by 3 so you can cancel out 3a and 3b and subtract 690-574 because we multiplied by 3
you are left with c+d=116

= 0.1 * 0.1
= 0.01
“ 0.01 > 0.0001 > 0.00001 > 0”
Therefore, your answer should be: 0.1^2 (option D)

We can find out if the angles are the same by adding them
180 = 6x + 4x + 10 + 10x + 70
180 = 20x + 80
100 = 20x
x = 5
6x = 30
4x + 10 = 30
10x + 70 = 120
From this information, we can conclude that this is an obtuse triangle (iv.) and that this is and isosceles (ii.).
The answer is ii. and iv. which is B

{4z=8}
{3x-2z=11}
{x-4y+z=11}
Step-by-step explanation:
4z = 8
z = 8/4
z = 2
3x - 2z = 11
3x - 2.2 = 11
3x - 4 = 11
3x = 11 + 4
3x = 15
x = 15/3
x = 5
x - 4y + z = 11
5 - 4y + 2 = 11
-4y = 11 - 5 - 2
-4y = 4
y = 4/-4
y = -1
Solution → {x,y,z} = {5,-1,2}
Determine whether the ordered pair (6, 5) is a solution to the equation –2x +y = –7.
Yes, (6, 5) is a solution.
No, (6, 5) is not a solution.
Answer:
Yes, (6, 5) is a solution.
Step-by-step explanation:
We can answer this by using the ordered pair point (6,5) in the equation to see if it works:
–2x +y = –7
–2(6) +(5) = –7 ????
-12 + 5 = -7 ???
-7 = -7 YES

x = - 25/21
Step-by-step explanation:

(Hope this helps can I pls have brainlist (crown)☺️)
The solution to the equation 2/3 - 4x + 7/2 = -9x * 5/6 is x = 25/21.
To solve the equation: 2/3 - 4x + 7/2 = -9x * 5/6
Let's first combine like terms on the left side:
2/3 + 7/2 - 4x = -9x * 5/6
To add the fractions, we need a common denominator:
The common denominator for 3 and 2 is 6. So, we rewrite 2/3 as 4/6:
4/6 + 7/2 - 4x = -9x * 5/6
Now, we can add the fractions:
(4/6) + (7/2) = (8/12) + (42/12) = 50/12 = 25/6
The equation becomes:
25/6 - 4x = -9x * 5/6
Now, let's simplify further:
25/6 - 4x = -45x/6
To eliminate the fractions, we can multiply both sides by 6:
6 * (25/6 - 4x) = 6 * (-45x/6)
This simplifies to:
25 - 24x = -45x
Next, let's gather the x terms on one side of the equation:
-24x + 45x = 25
Combining the x terms:
21x = 25
Finally, solve for x by dividing both sides by 21:
x = 25/21
Therefore, the solution to the equation is x = 25/21.
