Answer:
b
Step-by-step explanation:
The non-fillee dots stop at the 98 row and the 0.2 column.
98 + 0.2 = 98.2
Answer:
y =
Step-by-step explanation:
Since y is inversely proportional to x the equation relating them is
y = ← k is the constant of proportionality
To find k use the condition when y = 7, x = 9
k = yx = 7 × 9 = 63
y = ← equation connecting x and y
First, write an equation system based on the problem
An equation for "the perimeter of a rectangle is 70 in" can be written as following
∴ 2l + 2w = 70 <em>(first equation)</em>
An equation for "the length is 11 in more than its width" can be written as following
∴ l = w + 11 <em>(second equation)</em>
Second, solve the equation by substitution method o find the dimension of the rectangle.
Substitute/plug l as (w+11) into the first equation
2l + 2w = 70
2(w + 11) + 2w = 70
2w + 22 + 2w = 70
4w + 22 = 70
4w = 70 - 22
4w = 48
w = 48/4
w = 12
The width of the rectangle is 12 in
Substitute w with 12 to the second equation
l = w + 11
l = 12 + 11
l = 23
The length of the rectangle is 23 in
Third, find the area of the rectangle
a = l × w
a = 23 × 12
a = 276
The area of the rectangle is 276 in²
