The answer is B. It is a result of the survey.
Simplify 2:4
you get 1:2
this means the larger is two times the smaller.
well, we have to use a system of equations.
we know two supplementary angles add up to be 180°.we can create our first equaition, using
smaller angle + larger angle = 180
s + l = 180
we can create our second equation using
two times the smaller = larger
2s = l
our two equations are:
2s = l
s + l = 180
now that we have the two equations, we can solve using subsitution to isolate the variable.
s + l = 180
s + (2s) = 180
simpify.
3s = 180
s = 60
the smaller angle has a value of 60.
now, remember that the larger angle is two times the smaller.
60 x 2 = 120
smaller angle: 60
larger angle: 120
we know this is correct because we know the smaller is 1/2 or 1:2 or 2:4 times the bigger, and the two angles add up to be 180 (60 + 120)
hope this helps and have a great day!
Answer:
4.8%
Step-by-step explanation:
21% of 18
following the BODMAS rule, OF means multiplication
and also this sign% always means 100
so,it will be 21/100 * 18/1
this a laptop so i cant put it in a fraction way.....okay
this is how it shows...21/100 * 18/1
lets divide....
21/100 * 18/1
we will use 2 to divide
2 in 100=50
2 in 18=9
so it will be 21/50 * 9/1
nothing can divide so we will multiply
21*9/50*1
189/50=3.78≈4.8%
The answer is 12
working backwards, 6×2 is 12
Answer:
B (-9,−57/8)
Step-by-step explanation:
we know that
If a ordered pair is a solution of the linear equation, then the ordered pair must satisfy the linear equation
we have
<u><em>Verify each case</em></u>
Substitute the value of x and the value of y in the linear equation and then compare the results
case A) (6,17/2)
For x=6, y=17/2
Substitute
-----> is not true
therefore
The ordered pair not satisfy the equation
case B) (-9,-57/8)
For x=-9, y=-57/8
Substitute
-----> is true
therefore
The ordered pair satisfy the equation
case C) (6,-39/8)
For x=6, y=-39/8
Substitute
-----> is not true
therefore
The ordered pair not satisfy the equation
case D) (6,-8)
For x=6, y=-8
Substitute
-----> is not true
therefore
The ordered pair not satisfy the equation
