Answer:
13 units
Step-by-step explanation:
absolute value helps but
itd just be 7-(-6) = 13
Answer:
5, 85
Step-by-step explanation:
Complementary angles add to 90 degrees
Let x = 1st angle
17x is the 2nd angle
x+17x = 90
18x = 90
Divide each side by 18
18x/18 = 90/18
x = 5
The first angle is 5
second angle is 18*5= 85
Answer:
y=21 when x =15
Step-by-step explanation:
Since you multiply 5 by 3 to get 15, you also multiply 7 by 3. Therefore y=21
Answer:
x = 6, y =3
Step-by-step explanation:
4x-7y=3
x-7y=-15
Multiply the first equation by -1
-4x+7y=-3
Then add this to the second equation to eliminate y
-4x+7y=-3
x-7y=-15
------------------
-3x +0y = -18
-3x = -18
Divide by -3
-3x/-3 = -18/-3
x = 6
Now find y
x -7y = -15
6 -7y = -15
Subtract 6 from each side
6-7y-6 = -15-6
-7y = -21
Divide by -7
-7y/-7 = -21/-7
y =3
Yea it is..................
