Answer:
Equation: 1.50x + 10 
34
Amount of rides Dan can go on: 16 rides
Step-by-step explanation:
We can represent this situation using this equation:
1.50x + 10 34
The $10 Dan has to pay as admission is the fixed number because it doesn't vary and always remains the same, so no x goes next to 10.
Each ride costs $1.50 so this is the variable number as it changes with how many rides Dan goes on, therefore an x will go next to 1.50 to represent the amount of rides Dan goes on.
Lastly, Dan has $34 to spare, so the amount spent has to be less than or equal 34.
Solve the equation for x to find the greatest amount of rides Dan can go on:
1.50x + 10 34 Subtract 10 from 34
1.50x 24 Divide 24 by 1.50
x 16
So, Dan has enough money to go on 16 rides or less.
Let's check this answer:
1.50(16) + 10 34 Multiply 1.50 by 16
24 + 10 34 Add 24 and 10
34 34

Answer:-3
Step-by-step explanation:
you take the 3x to the right side of the equal sign
you then change the sign of 3x to -3x
A perfect situation to use a proportion:
(3.9 x 10³³) / 1 = X / (2.45 x 10⁵) .
Solve that proportion for ' X ' in the usual way.
If you can't remember how to solve a proportion, then
THAT's what you have to go look up. It's much more
important to you right now than how much energy the
sun is putting out.
7.4 x 10⁴ mm is the same size as about 243 feet !
If the tracks on a DVD were that far apart, there would not be
room for very many tracks on a DVD. That's not reasonable.
If the tracks are 7.4 x 10⁻⁴ mm apart, then there are about
34,000 tracks in a stripe that's 1-inch wide. I have no idea
how they do this, but it's certainly more reasonable than the
other choice.
Answer is c. -2 (cannot be in the solution set of w/-2)
because.
a) -1/-2 = 1/2 and 1/2 < 1
b) 1/-2 = -1/2 and -1/2 <1
d) 2/-2 = -1 and -1 <1
but
c) -2/-2 = 1 and 1 = 1
