Answer:
A linear equation has the greatest x power at 1.
If you see an equation with only x (no x^2 or x^3 or stuff like that), you will know that it is linear.
Answer:
10y=27+7
10y=34
y=34/10
y=3.4
Step-by-step explanation:
Firstly 7 is added to 27
Then adding 7 and 27
Dividing 34 by 10
it's very simple, 694-72= 622
so in order for you to check you answer you do the opposite
694-72 would equal 622
622+72 would equal 694
Answer:
4.62%
Step-by-Step Explanation:
Ask yourself: "3 is what percent of 65?" and solve.
Percentage solution with steps:
Step 1: We make the assumption that 65 is 100% since it is our output value.
Step 2: We next represent the value we seek with <em>x</em>.
Step 3: From step 1, it follows that 100%=65.
Step 4: In the same vein, x%=3.
Step 5: This gives us a pair of simple equations:
100%=65(1)
x%=3(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100% / x% =65 / 3
Step 7: Taking the inverse (or reciprocal) of both sides yields
x% / 100% =3 / 65
---> x = 4.62%
Therefore, 3 is 4.62% of 65.
The answer is x=5. I've included the work in the picture attached.
