Answer: x=-2
Step-by-step explanation:
addition property of equality is adding the same number to both sides of an equation does not change the equation.
distributive property: a(b+c)=ab+ac
add 3 both sides of an equation.
6x-3+3=3x-9+3
simplify an equation
6x=3x-6
subtract 3x both sides of an equation
6x-3x=3x-6-3x
simplify
3x=-6
divide 3 both sides of an equation
3x/3=-6/3
simplify
-6/3=-2
the answer should be the negative sign.
x=-2
Hope this helps!
Thanks!
Answer:
18° and 72°
Step-by-step explanation:
Complimentary angles form 90°
We have an angle (x) 4 times larger than the other (y).
Well actually, a system of equations isn't required, so forget about x and y, just divide 90 by 5. This gives you 18, one of the angle's measurements is 18°. Multiply 18 by 4 and get 72. The other angle's measurement is 72°.
Answer:
