Answer:
x = 5
Step-by-step explanation:
4x + 2y + z = 24
2x - 3y - z = 2
5x + y + 2z = 21
-----------------
Eliminate z
Add the 1st and 2nd eqn
4x + 2y + z = 24
2x - 3y - z = 2
----------------
6x - 1y = 26 eqn A
Multiply the 2nd eqn by 2, then add the 3rd.
4x - 6y -2z = 4
5x + y + 2z = 21
----------------
9x - 5y = 25 eqn B
---------------
Now you have 2 eqns in 2 unknowns, not 3.
Multiply eqn A by 5 and subtract eqn B.
30x - 5y = 130 eqn A times 5
9x - 5y = 25 eqn B
-------------
21x = 105
x = 5
Answer:
x = 5 is the answer

Step-by-step explanation:
John
65s (small)
40m (medium)
45 L (large)
Susan
x small
176m
y large
From question:
Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box =Meaning same ratio
John ratio. Susan
s : m : L s : m : L
65 : 40 : 45. 13 : 8 : 9
13 : 8 : 9. x : 176 : y
x = (176/8)*13
=286
y = (176/8) * 9
= 198
Total number of nails in Susan box
= x + 176 + y
= 286 + 176 + 198
=660

ANSWER ALL THE QUESTIONS TO GET MARKED BRAINLYEST
Answer: 7/10, 7/10 and 3/10.
Step-by-step explanation:
7/10 = Between 1 and 10, the multiples of three are 3, 6, and 9. So the amount favourable outcomes is the total minus the multiples, 10-3 = 7. So 7/10.
7/10 = Between 1 and 10, the multiples of 2 are 2, 4, 6, 8, and 10. The multiples of 3 are 3, 6 and 9. That, gives 7 favourable outcomes (6 is a multiple of both but counted once) giving the probability of 7/10.
3/10 = The favourable outcome is 8 and above, so: 8, 9 and 10. There are 3 favourable outcomes which gives the probability of 3/10.
