Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Two classmates, Brittany and Quinn, plan to meet in the computer lab to type up their research papers. Brittany can type at a speed of 3 pages per hour, whereas Quinn can type 1 page per hour. So far, Brittany already has 4 pages typed up, compared to Quinn's 14 pages. Once they sit down and start typing together, the two students will reach the same page count before too long. How long will that take? What will the page count be?

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
