Mathematics
1 answer:
n200080 [17]3 years ago
8 0

Step-by-step explanation:

\frac{x}{8}  +  \frac{5}{2}  =  \frac{3}{2}

by taking L.C.M

\frac{2x + 40}{8}  =  \frac{3}{2}

cross \: the \: values

2(2x + 40) =  8 \times 3

4x + 80 = 24

4x = 24 - 80

4x =  - 56

x =  \frac{ - 56}{4}

x = - 14

3x + y - z= -6<br> 2x - y + 2z = 8<br> 4x + y - 3z = -21
Flauer [41]

Answer:

x=-1

y=4

z=7

Step-by-step explanation:

3x + y - z= -6(1)

2x - y + 2z = 8(2)

4x + y - 3z = -21(3)

(1)+(2): 5x+z=2(4)

(2)+(3): 6x-z=-13(5)

(4)+(5): 11x=-11

x=-1

so z=2-5x=7

y=-6-3x+z=4

The value of y is directly proportional to the value of x. If y =35 when x = 140, what is the value of y when x =70?
torisob [31]
17.5 because 140 divided by 35 is 17.5 and so is 70 divided by 35.
