4x + -1y = 10
Solving
4x + -1y = 10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
4x + -1y + y = 10 + y
Combine like terms: -1y + y = 0
4x + 0 = 10 + y
4x = 10 + y
Divide each side by '4'.
x = 2.5 + 0.25y
Simplifying
x = 2.5 + 0.25y</span>
Answer:
the second one is Irrational
Step-by-step explanation:
it's just simple math.
Answer:
Yes, they are equivalent
Step-by-step explanation:
Tell whether the rates are equivalent.
Rate formula = Speed(miles)/Time(hour)
1)7 1/2 miles for every 3/4 hour
Hence
Rate = 7 1/2 miles ÷ 3/4 hour
= 15/2 ÷ 3/4
= 15/2 × 4/3
= 5 × 2
= 10 miles per hour
2) 1/2 mile for every 3 minutes
Time = 60 minutes = 1 hour
3 minutes = x
x = 3/60
x = 0.05 hour
Hence
Rate = 1/2 mile ÷ 0.05 hour
= 0.5 mile ÷ 0.05 hour
= 10 mile per hour
Therefore, both rates are equivalent
gcf = 3
the factors of 12 are 1, 2, 3, 4, 6 and 12
the factors of 45 are 1, 3, 5, 9, 15 and 45
the greatest common factor of 12 and 45 is 3
18, 6, 13
because if you add 2 sides should be > other side
18+6>13
18+13>6
