What is 1 6/7 -1 4/11

Answers

Answer 1

Answer: Convert both numbers to improper fractions, and to do that, multiply the denominator and whole number, and add the numerator.

If done correctly, you should get 13/7 - 15/11.

Now, we have to find the LCM of both denominators.
77 is the LCM.

77 is the LCM.

You needed to multiply 7 by 11 to get 77, so multiply 13 by 11, too.
13 x 11 = 143
We get 143/77.

Do the same with the other fraction.
You needed to multiply 11 by 7 to get 77. So multiply 15 by 7.
15 x 7 = 105
We get 105/77

Now you can subtract.

143/77 - 105/77 = 38/77

Answer 2

Answer: LCD = 77
1 66/77 - 1 28/77= 38/77

How can I solve this system of equation with substitution 2a+2x=18 and a+3x=17

Answers

first solve for one variable
solve for a in second eqatn

minus 3x both sides
a=17-3x
sub 17-3x for a in first equaiton
2(17-3x)+2x=18
34-6x+2x=18
34-4x=18
minus 34 both sides
-4x=-16
divide both sides by -4
x=4
sub back
a=17-3x
a=17-3(4)
a=17-12
a=5

a is 5
x=4

WORK SECTION (without thoughts)
2a+2x=18 to a+x=9
a+3x=17

a=17-3x
(17-3x)+x=9
17-2x=9
-2x=-8
x=4

a=17-3(4)
a=17-12
a=5

x=4
a=5

Answer:

3xpi/2 is 270 degree counter-clockwise from Ox

That time P(x,y) is (0,-1)

=> x= 0 and y = -1 as you can see in picture.

=> Cos 3pi/2 = x = 0

=> Sin 3pi/2 = y = -1
