Namely, how many times does 3¾ go into 78?  well, is just their quotient.

let's firstly convert the mixed fraction to "improper", and then divide,

so, if we nevermind the 4/5 part, only 20 whole of those then.

Question
Which of the following is not an appropriate unit for acceleration? A.kg/s2 B.mi/hr2 C.m/min/sec D.cm/sec2
Solution 1

Which of the following is not an appropriate unit for acceleration?

kg/s2mi/hr2m/min/seccm/sec2

answer- kg/s2
Solution 2

Answer:

A.kg/s²

Step-by-step explanation:

A kilogram, or kg, is a measure of mass.  This would not be a good unit for acceleration; acceleration is a measure of how far something goes in a given amount of time.  It is a measure of distance over time, not mass over time.

Question
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!
Solution 1

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.

Solution 2
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.
