Dr. Potter provides vaccinations against polio and measles.

Mathematics
1 answer:
zaharov [31]3 years ago
4 0

Answer:

28 polio vaccinations and 32 measles vacinnacions.

Step-by-step explanation:

x= polio vaccinations

y= measles vaccinations


here we have an ecuation system:

x+y=60 (vaccinations)

2x+4y=184 (doses)

In order to solve it I will solve the x in the first ecuation:

x=60-y

And replace it on the other ecuation:

2(60-y)+4y=184 -----> 120-2y+4y=184------>2y=64------->y=32

Now I replace this result in x=60-y, so x=28.

Carmen wants to join a gym. Gym A costs $26.76 plus an additional $4 for each visit. Gym B has no initial fee but costs $12.92 f
joja [24]

Answer:

After 3 visits both plans will cost the same.

Step-by-step explanation:

Gym A costs $26.76 plus an additional $4 for each visit.

Gym B has no initial fee but costs $12.92 for each visist.

The cost for gym A can be written as

C= $26.76 + 4(x)  where x is the number of visits to the gym A

The cost for gym B can be written as

C= $12.92 (x)  where x is the number of visits to the gym B

Both costs will be equal

12.92x= 26.76 +4x

12.92x-4x= 26.76

8.92x= 26.76

x= 26.76/8.92

x= 3

after 3 visits both plans will cost the same.

Check

12.92x= 26.76 +4x

12.92*3= 26.76 +12

38.76= 38.76

ABC Corp. has outstanding accounts receivable totaling $6.5 million as of December 31 and sales on credit during the year of $24
Elden [556K]

Answer:

$378,000

Step-by-step explanation:

The computation of the bad debt expense for the year is shown below:

Bad debt expense = Outstanding account receivable × estimated percentage given - credit balance of allowance for doubtful account

= $6,500,000 × 0.06 - $12,000

= $390,000 - $12,000

= $378,000

We simply deduct the credit balance from the estimated balance so that the correct amount could arrive

Jimmy collects nickels and dimes. Right now, he has a total of 40 coins in his piggy bank. If there are seven times as many dime
Colt1911 [192]
Number of nickels plus number of dimes equals total number of coins
so
n + d = 40

then they tell us that "there are seven times as many dimes as there are nickels"
this translates to
d = 7n

we then plug that into our first equation
and get
n + 7n = 40

then we solve for n
add like terms
8n = 40

then divide both sides by 8
n = 40/8 = 5

therefore Jimmy has 5 nickels

Solve the x <br> 1/3x + 5&gt; 10
kotykmax [81]

Answer:

The solution to the inequality is:

\frac{1}{3}x+5>10\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>15\:\\ \:\mathrm{Interval\:Notation:}&\:\left(15,\:\infty \:\right)\end{bmatrix}

The solution graph is also attached below.

Step-by-step explanation:

Given

We are given the expression

\frac{1}{3}x+5>10

To determine

Solve for x

Given the expression

\frac{1}{3}x+5>10

Subtract 5 from both sides

\frac{1}{3}x+5-5>10-5

Simplify

\frac{1}{3}x>5

Multiply both sides by 3

3\cdot \frac{1}{3}x>5\cdot \:3

Simplify

x>15

Thus, we conclude that:

x>15

Therefore, the solution to the inequality is:

\frac{1}{3}x+5>10\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>15\:\\ \:\mathrm{Interval\:Notation:}&\:\left(15,\:\infty \:\right)\end{bmatrix}

The solution graph is also attached below.
