Answer:
Step-by-step explanation:
Remark
2 angles are complementary means that 2 angles add up to 90°. That is the guiding princeple behind the problem.
Givens
Let the smallest angle = x
Let the largest angle = 4x + 30
Equation
4x + 30° + x = 90° Combine like terms on the left
Solution
5x + 30 = 90 Subtract 30 from both sides.
5x + 30 - 30 = 90 - 30 Combine
5x = 60 Divide both sides by 5
5x/5 = 60/5
x = 12
Answer
- smallest angle = 12
- Larger angle = 4*12 + 30 = 78
Answer:
Step-by-step explanation:
I will use substitution
We will substitute the answer for y into the bottom equation
x+(4x+3)=-2
5x+3=-2
5x=-5
x=-1
Now solve for y
(-1)+y=-2
y=-1
Write as an ordered pair
(-1.-1)
The answer to the problem is -25
Answer:
1.02*103= 13.06 and 2x10-4=16
Step-by-step explanation:
times the normal like a normal three digit by three digit but move the decimal to digits to the left due to the hundredths place and the second one is like pemdas
Answer:
(-1, -5)
it is a absolute value equation :)
