Answer: 5+3 times 4+2 is 48
Step-by-step explanation:
<span> For example, <span>x </span>> 6 or <span>x < </span>2. The solution to this compound inequality is all the values of <span>x </span>in which <span>x </span>is either greater than 6 or x is less than 2. You can show this graphically by putting the graphs of each inequality together on the same number line.</span>
The graph has an open circle on 6 and a blue arrow to the right and another open circle at 2 and a red arrow to the left. In fact, the only parts that are not a solution to this compound inequality are the points 2 and 6 and all the points in between these values on the number line. Everything else on the graph is a solution to this compound inequality.
<span>Let’s look at another example of an or compound inequality, x > 3 or x</span> <span>≤ </span>4. <span>The graph of </span>x<span> > 3 has an open circle on 3 and a blue arrow drawn to the right to contain all the numbers greater than 3.</span>

Answer:
Step-by-step explanation:
On the day of the canteen, 800 coupons were sold, the price of each coupon was RM 30 and RM 50 respectively. The amount of money earned from the sale of coupons was RM30000. How many copies of RM30 and RM50 coupons were sold?
Let:
RM 30 = x
RM 50 = y
x + y = 800 - - - (1)
30x + 50y = 30000 - - - (2)
From (1)
x = 800 - y
Put x = 800 - y in (2)
30(800 - y) + 50y = 30000
24000 - 30y + 50y = 30000
24000 + 20y = 30000
20y = 30000 - 24000
20y = 6000
y =
