Answer:
43.75 miles
Step-by-step explanation:
You divide the 35 by 4 and then just add it to the original distance of 35 miles. 35/4=8.75
8.75+35=43.75
Answer:
-20/3
Step-by-step explanation:
First simplify the left side of the equation
243^(1/5x)= (243^1/5)^x
=( )^x
= 3^x
Now that the left side is simplified, let's move to the right side
81^(x+5)=( )^(x+5) simplify 81 to base 3^4
= use the product of powers property to multiply the exponents together
=
With both sides simplified, let's rewrite the equation, this time in simplified terms
=
x=4x+20 because both the bases are same, their exponential value must also be equal
-3x=20 solve the algebraic equation for x
x=
A and B because if you look on a meter stick
So we want to know when the cost of each is the same:
2.5m=7.5+m subtract m from both sides
1.5m=7.5 divide both sides by 1.5
m=5
So renting 5 movies costs the same from either store. ($12.50)
Answer:
(0, -4)
Step-by-step explanation:
We can just substitute the y's like this: 2x - 4 = -2x - 4
Move like terms to one side by adding 2x to both sides
2x - 4 = -2x - 4
+ 2x + 2x
4x - 4 = - 4
Add 4 to both sides
4x - 4 = - 4
+ 4 + 4
4x = 0
Divide both sides by 4
4x/4 = 0/4
x = 0
Plug in the new x into one of the original equations
y = 2(0) - 4
y = 0 - 4
y = - 4
