Answer:
Step-by-step explanation:
Proportional relationship means,
x ∝ y
x = ky
where 'k' is the proportionality constant.
From table (1),
Therefore, relationship is not proportional.
From table (2),
True.
So the relationship will be proportional.
From table (3),
Which is constant.
Therefore, relationship will be proportional.
From table (4),
Which is constant for every term.
Therefore, relationship will be proportional.
You do like terms 4 3/12 - 3 6/12 = 3/4.
Answer: r = 3/4.
You will have 2 equations.
30x+20y=1100
and
x+y=45
by putting it into standard form
-(30/20)x+55=y
you can now solve finding the answer to be 20 for x and 25 for y.
Plug it into the original equation to find it correct and then plug it into x+y
20+25=45
30*20+25*20=1100
Answer:
<h3>So the answer is that 10 5/6 as a decimal is 10.833333333333.</h3>
Answer:
x=−12
Step-by-step explanation:
Let's solve your equation step-by-step.
7(x+3)=5x−3
Step 1: Simplify both sides of the equation.
7(x+3)=5x−3
(7)(x)+(7)(3)=5x+−3(Distribute)
7x+21=5x+−3
7x+21=5x−3
Step 2: Subtract 5x from both sides.
7x+21−5x=5x−3−5x
2x+21=−3
Step 3: Subtract 21 from both sides.
2x+21−21=−3−21
2x=−24
Step 4: Divide both sides by 2.
2x
2
=
−24

x=−12
Answer:
x=−12
