Answer:
C. Infinite solutions
Step-by-step explanation:
I'll use the equal value method and make the second equation equal 6 instead of 18, so I have to divide the entire equation by 3
(6x+15y=18)/3 = 2x +5y = 6
The second equation is the same thing as the first one, meaning no matter what value they will equal the same thing, also meaning there are infinite solutions
180 - 18 = 162
180cm is the longest length and 18 cm is the shortest length.
No because of how the slope is
Answer:
Infinitely many solutions.
Step-by-step explanation:
2x+y=3
6x=9-3y
-------------
y=3-2x
6x=9-3(3-2x)
6x=9-9+6x
6x=6x
infinitely many solutions
Answer:
8 4/15
Step-by-step explanation:
Rewriting our equation with parts separated
= 5 + 2/3 + 2 + 3/5
Solving the whole number parts
5 + 2 = 7
Solving the fraction parts
2/3 + 3/5 = ?
Find the LCD of 2/3 and 3/5 and rewrite to solve with the equivalent fractions.
LCD = 15
10/15 + 9/15 = 19/15
Simplifying the fraction part, 19/15,
19/15 = 1 4/15
Combining the whole and fraction parts
7 + 1 + 4/15 = 8 4/15
