Answer:

w = -4

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Equality Properties

Step-by-step explanation:

Step 1: Define equation

-5 - 3w = 7

Step 2: Solve for w

Add 5 to both sides: -3w = 12
Divide -3 on both sides: w = -4

Step 3: Check

Plug in w to verify it's a solution.

Substitute: -5 - 3(-4) = 7
Multiply: -5 + 12 = 7
Add: 7 = 7

And we have our final answer!

Morgan is working two summer jobs, making $19 per hour lifeguarding and making $6 per hour walking dogs. In a given week, she ca

Alexxx [7]

Answer:

w+d≥14

Step-by-step explanation:

Here is the full question

Morgan is working two summer jobs, washing cars and walking dogs. She must work no less than 14 hours altogether between both jobs in a given week. Write an inequality that would represent the possible values for the number of hours washing cars, w, and the number of hours walking dogs, d, that Morgan can work in a given week.

Morgan must not work less than 14 hours. This means that the least amount of hours she can work would be 14 hours. This would be represented by the greater to or equal to sign (≥)

So the time she would spend working = w+d≥14

9. Simran had some ₹2 and ₹ 5 coins.She exchanged them for ₹ 10 coins. If the number of ₹ 5 coins is one less than the number of

sertanlavr [38]

Answer:

Step-by-step explanation:

Let x be the number of 2 coins and y be the number of 5 coins. Let z be the number of 10 coins she exchanged. Then, we have the first equation

$2x+5y = 10z$

Since she has one 5 coin less than 2 coins, then y=x-1. So we get the equation

$2x+5(x-1) = 10z$

which is equivalent to

$7x-5 = 10z$

If we add 5 on both sides and factor out on the right by 5 we get

$7x = 5(2z+1)$

We can solve for x and get

$x = \frac{5(2z+1)}{7}$

Since x represents the number of 2 coins, we must have that x is an integer. That is, we cannot have, for example 1.5 2 coins. Since 7 doesn't divide 5, we must have that 7 divides 2z+1. That is, the value of z is such that the number 2z+1 is multiple of 7. That is 2z+1 = 7p where p is an integer.

If that is the case, then

x = 5p, then y = 5p-1. By having 2z+1 = 7p, we are forcing that p is an odd integer, so we have infinite solutions. For each value of p that is an odd integer, then x=5p and y=5p-1 is a solution to the problem
