Answer:
infinite solutions
Step-by-step explanation:
The coefficient of x in the first equation is 3 times the coefficient of x in the second equation. This means we can eliminate x by subtracting 3 times the second equation from the first:
(15x +12y) -3(5x +4y) = (18) -3(6)
0 = 0 . . . . . simplify (true for all values of x or y)
The system of equations has an infinite number of solutions.
Answer:
1a. 1.5
1b. 0.38
Step-by-step explanation:
a.
one full grid is full (1) and half a grid is full (0.5)
b.
there are 100 squares and 38 of them are filled in,so you divide 38 by 100 which is 0.38
Answer: 25
Step-by-step explanation:
(4x-12)+(3x+17)=180
Answer:
D
Step-by-step explanation:
Put n as 48 and solve.
-11 + (48 - 1)(-3)
- 11 + (47)(-3) = -152
Divide second term by first term u will get common ration here 1/2 is the common ration
