Answer:
a. 33 sq.m
b.33x sq.m
Step-by-step explanation:
In a) formula of area of rectangle is:
Area= length * width
where 3m is width and 11m is length
Now area = 3 *11
area= 33 sq.m
In b) formula is same as above
area= 3x * 11
area= 33x sq.m
Good evening,
Answer:
x > 5
x ≤ 12
Step-by-step explanation:
Visualize as if the inequality symbols are equal signs and then solve it as you would for a normal equation, note if you divide by two negative numbers at all you then switch the sign.
On a number line, an inequality sign without the “equal to” is plotted with an open circe.
An inequality sign, with the “equal to” is plotted with a closed circle.
3x - 7> 8
Add seven on both sides, we do this because we want to eliminate the 7 from one side.
3x > 15
Divide both sides by 3, we do this because you want to get rid of the 3 from x.
x > 5
As for the second inequality.
Divide both sides by -3, as I mentioned earlier switch the side since we are dividing by two negative numbers.
x ≤ 12
For the greater than inequality x > 5, plot a open circle on 5 and draw the line going to the right.
For the less than or equal to inequality x ≤ 12, plot a closed cirlce on 12 and draw the line going to the left.
A unique trick is to graph the line based on the direction (right or left) the inequality symbol is pointing to.
Answer:
D
Step-by-step explanation:
Answer:
₹2835
Step-by-step explanation:
Working out discount of 10% of jeans at ₹1450:
10% of 1450 = 1450/10 = ₹145
the price would now be ₹1450 - ₹145 = ₹1305
Working out discount of 10% of a shirt at ₹850:
10% of 850 = 850/10 = ₹85
the price would now be ₹850 - ₹85 = ₹765
so the price of two shirts = ₹765 × 2 = ₹1530
the total the customer would have to pay:
₹1305 + ₹1530 = ₹2835
