Answer:
x = 23/5 and y = 7/20
Step-by-step explanation:
2x + 8y = 12 and 3x - 8y = 11 are two given equations
Now,
<u>Step </u><u>1</u><u>:</u>
2x + 8y = 12 ...(1)
3x - 8y = 11 ...(2)
<u>Step </u><u>2</u><u>:</u>
From equation (2) we get the value of x
i.e.,
3x - 8y = 11
3x = 8y + 11
<em><u>x = 8y + 11/3</u></em>
<u>Step </u><u>3</u><u>:</u>
Now,
Put the value of <u>x = 8y + 11/3</u><u> </u>in equation (1) we get,
i.e.,
2x + 8y = 12
2(8y + 11/3) + 8y = 12
16y + 22/3 + 8y = 12
16y + 22 + 8y(3)/3 = 12
16y + 22 + 24y/3 = 12
16y + 24y + 22 = 12 * 3
40y = 36 - 22
40y = 14
y = 14/40
<em><u>y = 7/20</u></em>
<u>Step </u><u>4</u><u>:</u>
Now,
Substitute the value of <u>y = 7/20</u><u> </u>in equation (2) we get,
i.e.,
3x - 8y = 11
3x - 8(7/20) = 11
3x - 56/20 = 11
3x - 14/5 = 11
3x = 11 + 14/5
3x = 11 * 5 + 14/5
3x = 55 + 14/5
3x = 69/5
x = 69/3 * 5
<em><u>x = 23/5</u></em>
Answer:
2620
Step-by-step explanation:
The tenth place value is 2 places after the decimal so round off from there
Answer:
Option C is correct.
Step-by-step explanation:
The intercept form of the equation of plane is given by:
.....[1]
where
a is the intercept of x-axes
b is the intercept of y-axes and
c is the intercept of z-axes
From the given diagram:
a = 2
b = 5
c = 4
Substitute these in equation [1] we have;
LCM of 2, 5 and 4 is 20
Multiply equation 20 both sides we get;
Therefore, the equation of plane that contains the given triangle is,
