Answer:
66 square inches
Step-by-step explanation:
First we have to find out the area of the original piece of metal. Since it is 9 by 9, we can multiply to find that it is 81 square inches. If we remove a 5 by 3 piece, which is equal to 15 square inches, we can subtract 15 from 81 to get the answer - the remaining metal is 66 square inches
Answer:
x = 36
Step-by-step explanation:
To obtain the value of x, we must first obtain the value of y and z as shown in the attached photo.
i. Determination of y
2x + y = 180 (angle on a straight line)
Rearrange
y = 180 – 2x
ii. Determination of z.
z + 4x = 180 (angle on a straight line)
Rearrange
z = 180 – 4x
iii. Determination of x
x + y + z = 180 (sum of angles in a triangle)
But:
y = 180 – 2x
z = 180 – 4x
Therefore,
x + y + z = 180
x + 180 – 2x + 180 – 4x = 180
Collect like terms
x – 2x – 4x = 180 – 180 –180
– 5x = – 180
Divide both side by – 5
x = – 180 / – 5
x = 36
Therefore, the value of x is 36.

The total sales of Kenneth is $ 12968.75
<h3><u>Solution:</u></h3>
Given that Kenneth got a pay check for $415 this week
He made 3.2% commission on total sales
To find: total sales of Kenneth
Let "t" be the total sales of Kenneth
Kenneth got a pay check for $415 this week and made 3.2% commission on total sales. Which means that 3.2 % of total sales has yielded $ 415
$ 415 = 3.2% of total sales
415 = 3.2% of t
Thus the total sales is $ 12968.75
