if we write the ratio 15 cookies to 40 cookies we will get the following ratio
15:40
to write in simplest form we have to find the highest common factor for both 15 and 40
the factors for both 15 and 40 are as follows
15 - 1,3,5,15
40 - 1,2,4,5,8,10,20,40
the highest common factor is 5
so we have to divide both ny 5 to get the simplest form
ratio in the simplest form is 3:8
Answer:
162 mL
Step-by-step explanation:
1.Convert all volumes to millilitres
(a) Chlorpheniramine
V = 100 mL
(b) Lidocaine
(c) Banana flavouring
2.Calculate the total volume
Chlorpheniramine = 100 mL
Lidocaine = 59
Banana flavouring = 2.5
TOTAL = 162 mL
2x+4y=0
substitute y with 0
2x+4(0)=0
solve the equation
2x+0=0
2x=0
divide by 2 on both sides
x=0
4x+8y=7
substitute y with 0
4x+8(0)=7
solve the equation
4x+0=7
4x=7
divide by 4 on both sides
x=7/4 or x=1 3/4 or x=1.75
3x-7y=-29
2x+2y=6
solve the bottom equation
3x-7y=-29
x=3-y
substitute for x
3(3-y)-7y=-29
solve the equation
y=19/5
now substitute for y
x=3-
solve for x
x=-4/5
the possible solution of the system is the ordered pair
(x,y)=()
Answer:
Step-by-step explanation:
we know that
To find the rate of text messages per hour, first divide the total messages by the total time in minutes
so
Convert to messages per hour
Remember that
