Answer:
(- 1, 1 )
Step-by-step explanation:
Given the 2 equations
y = 3x + 4 → (1)
y = x + 2 → (2)
Substitute y = 3x + 4 into (2)
3x + 4 = x + 2 ( subtract x from both sides )
2x + 4 = 2 ( subtract 4 from both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
Substitute x = - 1 into either of the 2 equations and evaluate for y
Substituting x = - 1 into (2)
y = - 1 + 2 = 1
Solution is (- 1, 1 )
You have to turn 65 into a decimal. That would be .65
They do 39/.65
You should get 60 as your final answer.
Square root of 11, 5, 6, square root of 40
Your starting equation is:
x/6 + 4 = 15
The first step would be to subtract 4 from both sides, to move all of the constants to the right side of the equation.
x/6 = 11
The final step is to multiply both sides by 6, to get rid of the fraction on the left side of the equation.
x = 66
Hope this helps!
It would take him 11 minutes
He is currently eating 4 a minute because 24 divided by 6 is 4 and if you divide 44 by 4 you get eleven.
