Answer:
to the first one the answer is 0. To the number 2 the answer is 2
I don’t know and i understand that the other one didn’t do it but did you already try searching it?
Multiply first equaton by 2 and add to the other equation
6x+6y=12
<u>5x-6y=15 +</u>
11x+0y=27
11x=27
divide both sides by 11
x=27/11
sub back
3x+3y=6
divide both sides by 3
x+y=2
(27/11)+y=2
2 and 5/11+y=2
minus 2 and 5/11 both sides
y=-5/11
x=27/11
y=-5/11
(27/11,-5/11)
Answer:
96 inches
Step-by-step explanation:
We can write a proportion to solve
60 inches x inches
--------------- = -------------
5 ft 8 ft
Using cross products
60 *8 = 5x
480 = 5x
Divide by 5
480/5 = 5x/5
96 = x
96 inches
Answer:
x= 13 degrees
Step-by-step explanation:
This is a 90 degree angle. We can create an equation to find x
68+x+9= 90
77+x= 90
-77 -77
x= 13 degrees
Hope this helps!
