- Marcos 2
Marcos is bringing 36 cookies to his book club, but he's not sure how many people will be there. He wants to write an equation that shows how many cookies each person will get in terms of how many people (symbol n) are there. - Cuboid - sum of edges length
Calculate the cuboid's dimensions if the sum of its edges is 19 cm. The body's diagonal size is 13 cm, and its volume is 144 cm³. The total surface area is 192 cm². - Three angles
The three angles of a triangle are (3x-2)°, (4x+5)°, and (2x-3)°, then find the angles. - Line equation:
Line equation: y-3=8/9(x-5) Solve for slope - I read
I read 24 pages of a book. Three-fifth part of the book is still left for reading. How many pages does the whole book have? - Two containers 2
Two containers, one large and one small, contain a total of 4 kilograms of bath salts. One-quarter of the bath salts from the large container are transferred to the small container, so the ratio of bath salts in the large container to that in the small on - Jason 4

If p and q are the zeroes of the quadratic polynomial f(x) = 2x2 - 7x + 3, find the value of p + q - pq. - Evaluate 37
Evaluate the function K(x) = 2x²+3x-2 what is the value of K(½) - Sarah's age
64 is 4 times the difference between Sarah's age, a, and 44. Assume Sarah is older than 44. Write an equation to determine Sarah's age (a). - Sam's Sam's age is x. His sister Jo is 2 years more than 1.1 times his age. Question: What is Jo's age in terms of x? Write an equation to find x if the sum of Sam's and Jo's ages is 44.
- Multiplied and subtracted
When a number is multiplied by ⅔ and subtracted from 7, the result is 2⅓. What is the number? - Exp decay
An element with a mass of 780 grams decays by 16.3% per minute. How much of the element is remaining after 16 minutes, to the nearest 10th of a gram?
- Overdraft account Many bank accounts never go below zero. However, some banks will allow a negative balance, at least for a short time, called an overdraft. It means someone has taken out, or 'drafted', more money than was in the account, to begin with. Hannah's account we
- The sum 40 The sum of the two numbers is 75. If the smaller number is 20 more than 1/5 of the larger number, find those two numbers. The large number is x, and the small number is y.
