Answer:
Left
50 feet
Right
16 inches
10 inches
Step-by-step explanation:
Here, we want to make a conversion and fill in the empty spaces
The scale is 1 foot is 1/8 inch
To convert from foot to inch, we multiply by 1/8
To convert from inch to foot, we multiply by 8
Thus, we have ;
Let’s fill in the left spaces first;
6.25 * 8 = 50 feet
Right spaces, top to bottom;
128 * 1/8 = 16 inches
80 * 1/8 = 10 inches
7 is the number increased by 5 = 12
<h3>Given Equation:</h3>
x = 7 + 3y
or, x - 3y - 7 = 0 ........ (i)
5x + 6y = 14
or, 5x + 6y - 14 = 0 .........(ii)
<h3>To Find:</h3>
The value of x and y.
<h3>Solution:</h3>
By dividing eq. ii by 2, we get
5/2x + 3y - 7 = 0 ........ (iii)
By adding eq. i and eq. iii, we get
15/2x = 0
or, <u>x = 0</u> ........(iv)
By putting eq.(iv) in eq. (i), we get
0 - 3y - 7 = 0
or, -3y = 7
or, <u>y = </u><u>-</u><u>7/</u><u>3</u>
<h2>Answer: ( 0, -7/3 )</h2>
The value of x and y is 0 and -7/3 respectively.
