In August, a giant panda named Lucky was born at the Silver City Zoo. In September, Lucky
weighed 3.07 pounds. Today, Lucky is weighed again and he is heavier than before. Now
Lucky weighs 10.81 pounds.
Use an equation to find the amount of weight Lucky gained between September and today.
Using linear equations, the amount of weight Lucky gained between September and today is 7.74 pounds.
What is a Linear equation?An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. The standard form of a linear equation in one variable is the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.So, in September, Lucky weighed = 3.07 pounds
Today's Lucky weighed = 10.81 poundsThe equation form is:
Let x = weight to find Lucky3.07 + x = 10.81This is a linear equationSo, now solve this linear equation and find 'x' as follows:
3.07 + x = 10.81=> x = 10.81 - 3.07=> x = 7.74Therefore, using linear equations, the amount of weight Lucky gained between September and today is 7.74 pounds.

Kaj needs to order some new supplies for the restaurant where she works. The restaurant needs at least 736 knives. There are currently 155 knives. If each set on sale contains 12 knives, what is the minimum number of sets of knives Kaj should buy?
Hence, the minimum number of sets of knives kaj should buy is 48 sets.
Given this, a restaurant must have at least 736 knives.
At the moment, it possesses 155 knives.
Every set includes 12 knives.
Let the number of knife sets be.
Reason: Minimum number of sets indicates ≥
This means ≤ the maximum amount of sets

Kali earns a 15.75 plus a flat fee of 50 from her job.
She wants to earn between 200 and 400.
Let 'x' denote her earning potential.
Then the inequality for her earning potential is given by,
200 ≤ 15.75x + 50 ≤ 400
We solve this inequality for x.
Subtract 50 from the inequality,
⇒ 200 -15 ≤ 15.75x ≤ 400 -15
⇒ 185 ≤ 15.75x ≤ 385
Divide by 15.75,
⇒ 11.746 ≤ x ≤ 24.44

Althea needs 134 ounces of cold cuts for a party. How many pounds and ounces does she need?
The number of pounds and ounces that we have in 134 ounces is; 8 pounds 6 ounces
How to carry out units conversion?
We know that in units conversion, there are different units and their conversion rates. For example;
1 meters = 100 cm
1000 meters = 1 kilometer
1000 grams = 1 kilograms
100 cents = 1 dollar
Now, we want to convert ounces to pounds.
The conversion rate for ounces to pounds is;
1 ounce = 0.0625 pounds
We are given 134 ounces of cold cuts for a party. Converting that to pounds gives us;
134 * 0.0625/1 = 8.375 pounds
Now, we want it in pounds and ounces and so we convert the decimal part to ounces
1 pound = 16 ounces
0.375 pounds = 0.375 * 16/1 = 6 ounces

At least 26 bags of cat chow is required for a period of one year to fulfil the demand at the wildlife shelter in North Carolina
Quantity of cat chow sold in each bag = 20 lb
Consumption in lb of cat chow per week in the wildlife shelter = 10 lb
Number of weeks in a year = 52 weeks
The total quantity of cat chow required for 52 weeks = Weekly consumption of cat chow*Number of weeks
= 10*52
= 520 lb
Number of bags required = Toal quantity of cat chow required for 52 weeks/ Quantity of cat chow sold in each bag

lan spent = 2x - 20
Total money spent = $130
⇒ 2x - 20 + x = 130
⇒ 3x - 20 = 130

I need help with 3x-2y=24 find the y and x intercept and the slope
3x-2y=24
3x - 2y + 2y = 24 +2y Adding 2y to both sides of the equation
3x - 24 = 2y + 24 - 24 Subtracting 24 from both sides of the equation
(3x - 24)/2= 2/2y Dividing by 2 on both sides of the equation
3/2x - 12 = y
From this form of the equation we deduce the slope (coefficient of x) is 3/2 and the y-intercept is equal to -12.
To find the x-intercept, we replace y= 0 in the equation and isolate x
3/2x - 12 = 0
3/2x - 12+12 = 0+12 Adding 12 to both sides of the equation
x= 12/(3/2) Isolating x
x= 8
The x-intercept is 8
