Answer:
B) 1.75 + 0.45m = 13.90
Step-by-step explanation:
To calculate the Taxi fare, we need to sum the fixed charge and the additional charge. Fixed charge ever is $1.75. The additional charge changes with the miles traveled (one mile costs $0.45, two miles $0.90, and so on), so we need multiply the charge ($0.45) by the miles m traveled.
1.75 + 0.45 m
The problem says that the fare was equals to $13.90 so the final equation is
1.75 + 0.45m = 13.90
20 boxes because 6 times 5 equals 30 so 4 times 5 is 20
"The quotient of the sum of 2 and number b, and 3" can be displayed as:
(2 + b)/3
If 1 ml of volume contains 1 mg of epinephrine, then 0.1 ml of volume contains 0.1 mg of epinephrine.
Let x be the number of ml you need.
Ratio: 1 ml is to 1 mg as x ml is to 0.1 mg
(1 ml)/(1 mg) = (x ml)/(0.1 mg)
Cross multiply.
1 * x = 1 * 0.1
x = 0.1
Answer: 0.1 ml
Answer:
x=5
y=7
Step-by-step explanation:
y = x+2 so plug that in the next equation as y
so it be --> 5x+(-4)(x+2)= -3 now use distributive property
(-4 times x)+(-4 times 2)= -4x+-8 replug that back in
5x-4x+-8 = -3 subtract your x
1x = x so ---> x+-8 = -3 now to get rid of -8 we have to add 8 to it
x= -3 but whatever you do to one side u do to the other so u have to add 8 to -3---> so it be x=5
now take that x=5 and plug it in to your first eqaiuton to get y
y=5+2 ---> y =7
