Answer: x-7
Step-by-step explanation:
Answer:
6 cm² + 6 cm²
12 cm²
surface area of the cuboid=12cm²-2 cm²
=10 cm²
Answer:
f = 2 1/4
Step-by-step explanation:
f-3/4=1 1/2
Add 3/4 to each side
f-3/4+3/4=1 1/2+3/4
f = 1 1/2 +3/4
Get a common denominator
f= 1 2/4 + 3/4
= 1 5/4
= 1 + 4/4 + 1/4
= 2 1/4
<em><u>The set of equations that represent this situation is:</u></em>
<em><u>Solution:</u></em>
Let "x" represent the smaller number
Let "y" represent the larger number
Given that,
<em><u>Six times a larger number is equal to the sum of a smaller number and 18</u></em>
Here "times" represents multiplication
Six times a larger number = sum of a smaller number and 18
6 x larger number = smaller number + 18
6y = x + 18
Thus,
<em><u>Also given that difference of twice the larger number and the smaller number is 6</u></em>
twice the larger number - smaller number = 6
2y - x = 6
Thus,
2y = x + 6
Thus the set of equations that represent this situation is:
4.5 feet. Divide 108 by twelve and you find out that the board is 9 feet long. Half of 9 is 4.5. Therefore, each piece is 4.5 feet long.<span />
