Answer:
|x – 25| ≤ 6
Step-by-step explanation:
Given:
Car run per gallon = 25 miles per gallon
Fluctuate value = 6 miles per gallon
Find:
Equation
Computation:
x ≤ 25 ± 6
|x – 25| ≤ 6
Answer:
50
Step-by-step explanation:
Using the experimental probability, first we have to find total amount paint then to find the amount of good quality forever paint we have to subtract the amounts of other paints from total amount.
Let x represents the amount of good quality forever paint sold.
Total amount of paint
...(i)
Experimental probability of paint sold will be better quality durable paint is


It is given that experimental probability of paint sold will be better quality durable paint is 


...(ii)
From (i) and (ii), we get



Therefore, 50 gallons good quality forever paint is sold.
It takes 250 g of pasta and 240 ml of sauce to make one batch of spaghetti and it takes 600g of pasta and 700ml of sauce to make one batch of lasagna.
Case 1: Pasta
The chef wants to make spaghetti and lasagna using more than 4000 g of pasta.
S denote the number of batches of spaghetti he makes and L the number of batches of lasagna he makes.
So the equation becomes :

Case 2: Sauce
chef wants to make spaghetti and lasagna using more than 5000 ml of sauce.
S denote the number of batches of spaghetti he makes and L the number of batches of lasagna he makes.
So the equation becomes:
Answer :
The two equations are :
For pasta: 
For sauce:
Answer:
7/56
Step-by-step explanation:
This is because there are 56 people and seven out of them are on the honor roll and have perfect attendance. You have a seven out of fifty-six chance of choosing them.
