Tripp and Rico are two dogs. Tripp weighs exactly 35 pounds more than Rico. Together, they weigh exactly 49 pounds. How much does each dog weigh? Please use Two-step equations!!!! plz, help!

Using a system of equations, it is found that Tripp weighs 42 pounds and Rico weighs 7 pounds.

What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are given as follows:

- Variable x: Tripp's weight.

- Variable y: Rico's weight.

Tripp weighs exactly 35 pounds more than Rico, hence:

x = 35 + y.

Together, they weigh exactly 49 pounds, hence:

x + y = 49

35 + y + y = 49

2y = 14 -> y = 7

x = 35 + y -> x = 42

Hence, Tripp weighs 42 pounds and Rico weighs 7 pounds.

Call the weights of the two dogs and .

We know that Tripp weights 35lbs more than Rico, or:

We also know that the total weight of both dogs is 49lbs.:

Now, by substitution:

Rico weighs 7lbs.

Then:

Tripp weighs 42lbs.

Which expression means 56? A) 5 × 5 × 5 × 5 × 5 × 5 B) 6 × 6 × 6 × 6 × 6 × 6 × 6 C) 6 × 5 D) 5 6

If u mean 5^6, it is 5 x 5 x 5 x 5 x 5 x 5

It isn't going to be anything with a 5 as a factor (if it has something multiplied by 5) because all multiples of 5 end in either 5 or 0 so it isn't A or C.

It isn't B because that expression has 7 6s and 6×6×6=216 which is already larger than 56.

That only leaves D

Hope this helps :)

Translate the verbal phrase into an inequality. Then solve the inequality. 6 less than the product of 3 and a number is no more than 15

Answer:

x≥7

Step-by-step explanation:

3x-6≥15

add 6 both sides

3x≥21

divide by 3

Just as there are simultaneous algebraic equations (where a pair of numbers have to satisfy a pair of equations) there are systems of differential equations, (where a pair of functions have to satisfy a pair of differential equations). Indicate which pairs of functions satisfy this system. It will take some time to make all of the calculations.

y_1' = y_1 -2 y_2 \qquad y_2' = 3y_1 - 4 y_2

A. y_1 = \sin(x) +\cos(x) \qquad y_2 = \cos(x) - \sin(x)

B. y_1 = \sin(x) \qquad y_2 = \cos(x)

C. y_1 = \cos(x) \qquad y_2 = -\sin(x)

D. y_1 = e^{-x} \qquad y_2=e^{-x}

E. y_1 = e^x \qquad y_2=e^x

F. y_1 = e^{4x} \qquad y_2 = e^{4x}

G. y_1 = 2e^{-2x} \qquad y_2 = 3e^{-2x}

As you can see, finding all of the solutions, particularly of a system of equations, can be complicated and time consuming. It helps greatly if we study the structure of the family of solutions to the equations. Then if we find a few solutions we will be able to predict the rest of the solutions using the structure of the family of solutions.

Answer: D and G.

Step-by-step explanation:

For options D and G we will show that both differential equations are satisfied. For the other options we will show the pairs don't solve one of the equations.

- A. and (when x=0 the left side is -1 and the right side is 1) so the equation is not satisfied.

- B. and so the equation is not satisfied.

- C. and so these pairs don't solve the equation .

- D. Since then . The first equation is satisfied, because . The second equation is also satisfied: .

- E. and so they don't satisfy the equation .

- F. and , then the equation is not satisfied.

- G. In this case, and . Computing derivatives, and . The first equation is satisfied, because . The second equation is also satisfied: .

How to find a unit rate from a table

In order to find a unit rate, the second part of the ratio must equal one. For example, let's say we want to find the ratio of 10/5. The second part of the ratio is 5. To get from 5 to 1, we must divide by 5. 5 / 5 = 1. However, what you do to the second part, you do to the first part. 10 / 5 = 2. The unit rate is 2:1.

one-gallon jugs of water are shipped in cartons containing 12 jugs. how many cartons are needed for 876 jugs to be shipped?

My best guess is that 73 cartons are needed. Here's how:

876/12 ( because the jugs are shipped in cartons containing 12) = 73

This is just a guess, I'm sorry if someone proves me wrong, but this is what I have.

876/12 ( because the jugs are shipped in cartons containing 12) = 73

Beth swam laps to raise money for a charity. Beth raised $15 plus $0.65 per lap that she swam. She raised a total of $80.00. Let x represent the number of laps Beth swam. What expression completes the equation to determine the total number of laps Beth swam? How many laps did Beth swim?

Answer

Find out the how many laps did Beth swim and write expression the total number of laps Beth swam .

To proof

As given

Beth swam laps to raise money for a charity.

Beth raised $15 plus $0.65 per lap that she swam.

She raised a total of $80.00

Let x represent the number of laps Beth swam.

Than the expression becomes

15 + 0.65× x = 80 .00

Simplify

15 + 0.65x = 80

0.65x = 80 -15

0.65x = 65

x = 100

Therefore the number of laps did Beth swim be 100 .

Hence proved

15 + .65x = 80

15 + .65x = 80

15 - 15 + .65x = 80 - 15

.65/.65x = 65/.65

x = 100

Beth swam 100 laps.

15 + .65x = 80

15 - 15 + .65x = 80 - 15

.65/.65x = 65/.65

x = 100

Beth swam 100 laps.
