Answer:
he will have 40 kg
Step-by-step explanation:
10:5=2
20 x 2 = 40
Answer:
4600
Step-by-step explanation:
STEP 1: Determine type of progression
Since d1 = d2, it is Arithmetic progression, with a common difference of 4
STEP 2: Evaluate the sum
Answer: Obviously you pay 20% if they pay 80%. You would pay $2019.60
Step-by-step explanation:
If they pay 80% take that a subtract it from $10908.00 and 20% should be $2019.60
(a) Answer: One solution.
Explanation: two lines that have same slope with opposite sign will necessarily cross each other at a single point, as one is "pointing uphill" and the other "downhill."
(b) Answer: Infinitely many solutions.
Explanation:
2x + 3y = 5.5
4x + 6y = 11 | divide by 2
-->
2x + 3y = 5.5
2x + 3y = 5.5
--> equations are identical.
2x + 3y = 2x + 3y
so any (x,y) will satisfy this equation. This means infinitely many solutions.
(c) Answer: One solution
Explanation:
Continuing the two lines it becomes obvious they will cross at one point (the solution)
(d) Answer: No solution
Explanation: If the two lines are parallel, they will never cross (by definition of "parallel"). Therefore there will be no solution to the corresponding linear system.
