Let's first write down the equations which we will require to solve for this problem.
Equation No. 1 -
x km/h = y mph
Equation No. 2 -
8 km/h = 5 mph
First of all, we will make y the subject by calculating the km/h when mph = 1. We will accomplish this by dividing both sides by 5 as displayed below:
Equation No. 2 -
8 km/h = 5 mph
5 mph = 8 km/h
5 / 5 mph = 8 / 5 km/h
1 mph = 8 / 5 km/h
Through this, we have found out:
m = 8 / 5
We will use the y = mx formula in order to obtain our final equation. We will substitute the value given in the second equation into the formula.
y = mx
y = ( 8 / 5 ) x
Answer:
Cost increases to $330.
The percent increase here would be:
= (New price - Old price )/ Old price
= (330 - 250) / 250
= 0.32
= 32%
Cost increases to $330 and charges $50 baggage fee
= (New price - Old price )/ Old price
= (330 + 50 - 250) / 250
= 0.52
= 52%
Answer:
=12x−9
Step-by-step explanation:
−3x+ −9 +15x
=(−3x+15x) +(−9)
=12x+−9
I hope this helps ^^
I think the answer is 2x10^1
Answer:
Step-by-step explanation:
this ratio of (1/8) to (1/4) can be written as a fraction
however, since we want to find out how much salt is needed for one teaspoon of baking soda, salt is the numerator (top) of the fraction and baking soda is the denominator (bottom) of the fraction
(1/8)/(1/4)
(1/8)x(4/1) when you divide fractions the second fraction switches the top and bottom
(1/8)x4
4/8
1/2
1/2 or 0.5 teaspoons of salt are needed per teaspoon of baking soda
