Answer:
The values of x = y = z = 1
Step-by-step explanation:
Given three linear equation as ,
x + 2y + z = 4 .......a
4y - 3z = 1 .......b
y + 5z = 6 ........c
Now solve eq a and b first
4y - 3z = 1 × 5
y + 5z = 6 × 3
Or, 20y - 15z = 5
3 y + 15z = 18
so ,(20y - 15) + (3y +15 ) = 5 +18
or, 23 y = 23
∴ y = 1
Now put this y value in eq c
so , 1 + 5z = 6 ,
Or, 5z = 6-1 =5
∴ z = 1
Again put this y and z value in eq a
so, x + 2(1) + (1) = 4
Or, x = 4 -3
∴ x = 1
Hence from the above solutions , the value of x = y =z = 1 Answer
Answer:
I believe the answer is b=1/2(d-g)
Step-by-step explanation:
multiply to remove the variable from the denominator.
P=2L+2W
P=2*20+2*15= 40+30=70 in
A=W*L=20*15=300 in²
The answer is $2.90
Hope that helps
Answer:
$19.99
Step-by-step explanation:
There are 12 months in a year, so in 2 years, there are 24 months.
Find how much each payment will be by dividing the cost by 24:
479.76/24
= 19.99
So, each payment will be $19.99
