For get the solution of this task, we must make the system of equations.First it: "The quotient between the sum of two numbers and one of them is equal to 3" Let's take two values: a and b.(a+b)/b=3 --- it's will be first equation in our system.
and "The inverse of double the sum of them and equal to 1/6"1/2(a+b)=1/6 it's will be second equation in our system.
Attention at parenthesis.
System(a+b)/b=31/2(a+b)=1/6
by the first equation:(a+b)/b=3a+b=3ba=2b --- we will use this equation for second equation in system
1/2(2b+b)=1/61/3b)=1/63b=6b=2 and a=2b, that's mean a=1.The answer is pair (1;2)
A
Sq rt each side you get
X+3= +-8
X+3=8
-3. -3
X=5
X+3=-8
-3. -3
X=-11
You have to simplify the expression. Evaluate the power which would be your square root (2). So 5×5=25 then add 3 to 25 and the answer will be 28.
Answer:
x = 54°
y = 144°
Step-by-step explanation:
x° + 36° = 90° (complementary angles)
Subtract 36° from each side of the equation
x° = 90 - 36°
x = 54°
y° + 36° = 180° (angles on a straight line/supplementary angles)
Subtract 36° from each side
y° = 180° - 36°
y = 144°
