Answer:

11

Step-by-step explanation:

she divides the number of pencils equally

so the number of pencils per student is 152/13

which is 11.692...

but she can't give 0.69 of a pencil so she gives only the whole part 11

and she keeps 9 pencils

A veterinarian is changing the diets of two animals, Simba and Cuddles. Simba currently consumes 1,520 Calories per day. That nu
kykrilka [37]

Answer:

6 days ; 2300 calories

Step-by-step explanation:

Given the following :

Current consumption :

Simba = 1520 calories per day

Increases by 130 calories per day : After d days ;

S(d) = 1520 + 130d

Where ; d = number of days

Cuddle = 3380 calories

Decreases by 180 calories each day; after d days ;

S(d) = 3380 - 180d

Pattern continues until they both consume same number of calories each day

S(d) = C(d)

1520 + 130d = 3380 - 180d

130d + 180d = 3380 - 1520

310d = 1860

d = 6

Number of calories they will be consuming them ;

Using : S(d) = 3380 - 180d

S(6) = 3380 - 180(6)

S = 3380 - 1080

S = 2300

They will be consuming 2300 calories by then.

Is my answer correct?
Black_prince [1.1K]

No, we do not multiply the first equation by 2 and then add it to the second equation. We have to multiply the first equation by 4.

To illustrate this point, consider system A:

\left\{ \begin{aligned}x - y &= 3 \\-2x + 4y &= -2\end{aligned}\right.

If we multiply the first equation by 2, we get

2x - 2y = 6

Now, if we replace the second equation with the sum of the second equation and 2x - 2y = 6, we get

\left\{ \begin{aligned}x - y &= 3 \\(-2x+2x) + (4y - 2y) &= -2 + 6\end{aligned}\right.

which simplifies to

\left\{ \begin{aligned}x - y &= 3 \\2y &= 4\end{aligned}\right.

This is not an equivalent system to System B. We can see that we ended up with a 2y = 4 equation.

In order to end up with a 2x = 10 second equation, we have to multiply the first equation of system A by 4 to get

4x - 4y = 12

If we replace the second equation with the sum of the second equation and 4x - 4y = 12, we get

\left\{ \begin{aligned}x - y &= 3 \\(-2x+4x) + (4y-4y) &= -2 + 12\end{aligned}\right.

which simplifies to

\left\{ \begin{aligned}x - y &= 3 \\2x &= 10\end{aligned}\right.

Otherwise, you are correct. The solution to system B is the solution to system A. Adding an equation to another does not change the system.

Isabella deposited $500 into a savings account at a local bank that earned 5% interest per year. How much interest does she earn
Marat540 [252]

Answer:

$25

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

putting time into years for simplicity,

12 months ÷ 12 months/year = 1 years,

then, solving our equation

I = 500 × 0.05 × 1 = 25

I = $ 25.00

The simple interest accumulated

on a principal of $ 500.00

at a rate of 5% per year

for 1 years (12 months) is $ 25.00.
