Step-by-step explanation:
4×-20=10y
4x/10-20/10=y
x/5 -2=y
x/5 +(-2)=y--------(1)
we have
y=mx+c----------(2)
comparing eq. 1 and 2,we get,
slope (m)=1/5
c= -2
Answer: Rizza got a profit of Php 67.20---B
Step-by-step explanation:
Profit = Selling Price - Cost Price
But
Selling price =Php10.00 x 24=240Php
Cost Price =Php172.80

Profit=Php240 -Php172.80
=Php 67.20
Answer=875miles 17.5miles per gallon
350miles x miles
________=_________
20gallons 50gallons
cross multiply
20x=17500
divide both sides by 20
x=875
875 miles can be traveled with 50 gallons of gas.
To find gas milage, which is essentially miles per gallon, simply divide the number of miles by the number of gallons
350miles 20gallons
350/20=17.5 miles per gallon
The number that produces a rational answer when added to 0.85 is; 193/180
<h3>How to identify rational numbers?</h3>
A rational number is an algebraic term expressed as a fraction. The fraction can also be in decimals but only if the decimal places are not repeating or not infinitely long. If they aren't, then these are called irrational numbers.
Now, let us convert 0.85 to a fraction. Thus;
0.85 = 85/100 = 17/20
From the given options, the only one that when added to 0.85 will yield a rational number is 2/9. This is because;
17/20 + 2/9 = 193/180
193/180 is a rational number.
The missing options are;
A. 2/9
B. 0.2645751311...
C. √2
D.
