Well you multiply the -4 to the 9 using and you will get -36 then you divide by -6 and you will get 6 simple as that
Albert´s ftather age=x
Albert age=y
We suggest this system of equations:
y=x-24
x+8=2(y+8)
we solve this system of equation by substitution method.
x+8=2[(x-24)+8]
x+8=2(x-16)
x+8=2x-32
x-2x=-32-8
-x=-40
x=40
y=x-24
y=40-24
y=16
Answer: Albert´s father is 40 years old, and Albert is 16 years old.
What is the question that you are wanting answered.
Answer:
y = 95° and x = 21°
Step-by-step explanation:
y + 85° = 180° { being co-interior angles }
y = 180° - 85°
y = 95°
y = 4x + 11°[ being vertically opposite angles ]
95° = 4x + 11°
4x = 95° - 11°
4x = 84°
x = 84° / 4
x = 21°
Hi!
<h3>Divide by -10 on both sides. </h3>
-10x/-10 < -100/-10
<h3>The inequality sign flips because we are dividing by a negative number. </h3>
<u>x > 10</u>
<h2>The answer is A x > 10</h2>
Hope this helps! :)
