Hey, Please help!!

Mathematics
1 answer:
Mazyrski [523]3 years ago
5 0

Step-by-step explanation:

1. d = rt

Divide t from both sides.

\frac{d}{t} = r

2. PV = nRT

Divide P from both sides.

V = \frac{nRT}{P}

3. \frac{x}{2} -g=a\\

Add g to both sides.

\frac{x}{2} = g + a

Now multiply by 2 on both sides.

x = 2(g + a)

(or, x = 2g + 2a)

4. g(h+\frac{3}{2} ) = 11

Divide g from both sides.

h + 1.5 = \frac{11}{g}

Now subtract 1.5 from both sides.

h = \frac{11}{g} -1.5

5. a(n-2)+5=bn\\

n = \frac{2a-5}{a - b}

SW=2x+y, WC= x-2y, W is the midpoint of SC, and SC=20, find the values of x and y.
zysi [14]

Answer:

x= 6

y = -2

Step-by-step explanation:

Given

SW = 2x + y

WC = x - 2y

SC = 20

Required

Determine x and y

Since W is the midpoint;

SW = WC = \frac{1}{2} * SC

SW = WC = \frac{1}{2} * 20

SW = WC = 10

Substitute 10 for SW and WC

2x + y = 10 --- (1)

x - 2y = 10 ---- (2)

Make x the subject in (2)

x = 10 + 2y

Substitute x = 10 + 2y in (1)

2(10 + 2y) + y = 10

20 + 4y + y = 10

20 + 5y = 10

Solve for 5y

5y = 10 - 20

5y = -10

Solve for y

y = -10/5

y = -2

Recall that x = 10 + 2y

x = 10 + 2(-2)

x = 10 -4

x= 6
