Answer:

3x = 27

Step-by-step explanation:

The addition property of equality, which is used to justify this step in the proof, states that we can add the same number to both sides of an equation and maintain equality. The only number we would want to add in this equation to solve it would be 1 (adding one cancels the subtracted 1); doing so cancels it on the left and gives us 27 on the right.

In a class of 24 people, the ratio of women to men is 3 to 1. How many women are in the class?

ryzh [129]

Answer:

There are 18 women in the class

Step-by-step explanation:

First of all this is a ratio topic and to solve it one needs to know that ratios are fractions so to solve it we will find first the sum of the fractions which is 3+1 and =4. Fully recognising through the question that the fractions or relation of the women to the men in the classroom is in a 3:1 ratio, we should multiply the fraction with the total number of people in the class which bring forth the result as 18!

John is at a local bait shop; he wants to buy bait for his fishing trip. At the store, they are selling live bait for $12 a poun

Monica [59]

The system of inequalities is: $x\geq 3$ and $12x+7y\leq 63$

Explanation

Let $x$ be the amount of live bait and $y$ be the amount of natural bait.

As John would like to get at least 3 pounds of live bait, so the first inequality will be: $x\geq 3$

Given that, price of live bait is $12 per pound and natural bait is $7 per pound. Also, he only has a budget of $63. That means, he can spend maximum $63

So, the cost for buying $x$ pound of live bait $=\$12x$ and the cost for buying $y$ pound of natural bait $=\$7y$

Thus, the second inequality will be: $12x+7y\leq 63$

which of the following is a point slope equation of a line with the point (-6,2) and a slope of 1/2?

wariber [46]

Answer:

y - 2 = 1/2(x + 6)

General Formulas and Concepts:

Algebra I

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate
y₁ - y coordinate
m - slope

Step-by-step explanation:

Step 1: Define

Identify

Point (-6, 2)

Slope m = 1/2

Step 2: Find

Substitute in variables [Point-Slope Form]: y - 2 = 1/2(x - -6)
Simplify: y - 2 = 1/2(x + 6)
