Each polio vaccination consist of four doses, and each measles vaccination consist of two doses. Last year, Dr. Potter gave a to

Mrac [35]

To solve this equation we need to set up a system of equations because we need to find out the value of 2 variables given 2 equations

Equation 1: Polio vaccination has 4 doses, measles vaccination has 2 doses, and he gave out 184 doses total

Equation 2: He gave 2 types of vaccinations: polio and measles, and he gave a total of 60 vaccinations.

To convert the word form of these equations, we first have assign polio and measles a variable to make them easier to keep track of

Lets just say that the number of polio shots = x and number of measles shots = y

Equation 1: 4 doses of x added with 2 doses of y equaled 184 doses total

4x+2y = 184

Equation 2: x vaccines added with y vaccines equaled 60 total vaccines

x + y = 60

We know have our system of equations

Equation 1: 4x+2y = 184

Equation 2: x + y = 60

To solve a system of equations, we can either do elimination or substitution, depending on which is easier.

In this case, substitution is pretty easy because for equation 2 we just need to have only 1 variable on a side then we can substitute it into equation 1

Equation 2: x + y = 60

Lets subtract x from both sides of the equation to "move" the x to the other side

y = -x + 60

And using y in terms of x, we can plug it into equation 1

Equation 1: 4x+2y = 184

4x+2(-x + 60) = 184

Now distribute the 2 to (-x+60)

4x-2x+120 = 184

Simplify by combining like terms

2x+120 = 184

Subtract 120 from both sides of the equation so all variables are on one side and the constants on the other

2x = 64

Divide 2 from both sides of the equation to isolate x, when we want to find

x = 32

Now we know the number of polio vaccines he gave, plug this into an equation to find y- the number of measles vaccine

Equation 2: x + y = 60

32 + y = 60

Subtract 32 from both sides to isolate y

y = 28

We know now that x, the number of polio vaccinations = 32 and y, the number of measles vaccinations = 28

Dr. Potter gave 32 polio vaccinations and 28 measles vaccinations last year.

Elsa's grandmother paid her x dollars a week to mow the lawn during the summer. Elsa decided to save some of her money and spend

Andrej [43]

Answer:

Amount of money Elsa spent= amount of money given by grandmother,x - amount of money saved.

Hence for the first four weeks, amount spent= 4(x-10) as she saved 10 per week for 4 weeks.

For the next eight weeks, amount spent= 8(x-15) as she saved 15 per week for 8 weeks.

Thus the answer would be the first option.

Misaki cut some wood for a bookcase she is building.She needs to find how many 1/3 ft boards she can make from a 5 ft board.Expl

N76 [4]

Answer: There are 15 boards that she can make from a 5 ft board.

Step-by-step explanation:

Since we have given that

Length of a board = 5 ft

Length of board she can make from the above board is given by

$\frac{1}{3}\ ft$

We need to find the number of boards she can make from a 5 ft board.

According to question,

$\text{Number of boards}=\frac{5}{\frac{1}{3}}\\\\\text{Number of boards}=5\times 3\\\\\text{Number of boards}=15$

Hence, there are 15 boards that she can make from a 5 ft board.

Hi can someone pls help me with this!!!

Eva8 [605]

the domain is the x value (first number) and the range is the y value (second number)

(if a number appears more than once in the domain or range, like in number 1 you don't have to write it again.)

to graph the domain and range you just plot the points,

and to map them you have to put the x values in the first oval and the y values in the second, usually in order from smallest to largest.

then you have to draw arrows connecting each x value to the y value that was in the same pair. just like when writing down the domain/range, if a number comes up again you don't have to write it down again. instead, you might have two or more arrows connecting to the same number.
