Answer:
64
Step-by-step explanation:
Your welcome
18 you multiply the 6 to the 3 so if it took her 3 minutes for 2 it will take her 18 minutes for 12
If you simplified a two-equation system and all variables were eliminated, two outcomes are possible.
If the final equation is a true equation, like 3=3, then the system has an <em>infinite number of solutions </em> (the equations graph the same line, and all points appear on both graphs)
If the final solution is a mathematically false equation, like 0=-8, the system has no solution. The lines are parallel and never intersect (have a solution)
You're going to want to solve the equations then mark them onto the lines. Number four would turn into -6 *Is greater than* 5n + 9 and number six would turn into -2p *is less than or equal to* -2.
Answer:
x = 9
Step-by-step explanation:
The big triangle is similar to smaller one so we can use the side lengths' proportion to find x:
7/4 = (x-3)+8/8
7/4 = (x+5)/8 cross multiply expressions
56 = 4x + 20 subtract 20 from both sides
36 = 4x divide both sides by 4
9 = x
