So the width should be 21 cm, to have a length of 99 cm and a perimeter of 240 cm in linear equations.
What are instances of linear equations?
- Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5. When an equation is given in this format, finding both intercepts is rather simple (x and y).
- Because (0,y) is the location where the line crosses the y-axis, the value of y when x is 0 is referred to as the y-intercept.
- The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.
240 = 2(99) + 2x
240 = 198 + 2x
42 = 2x
21 = x

45/9 or 45 divided by 9 is equal to 5 because
9 times 5 is equal to 45.
Answer:
= -1/4x +3/7y+10
Step-by-step explanation:
3/7y=x/4+10=-1/4x+3/7y+10
Answer:
f(x)=0.5x+4
Step-by-step explanation:
- the y intercept is 4 (that's the point where the line is crossing the y-axis)
- the slope of the line is one half (rise over run shows that the slope of the line is 1/2)
- if you plug in the numbers in y = mx+b you get y = 0.5x + 4
(m=slope, and b=y intercept)

<h3>Answer:</h3>
13 years old
<h3>Explanation:</h3>
Let g and m represent grandfather's age now and my age now. The relation 5 years ago was ...
... g -5 = 5(m -5)
The relation in 3 years will be ...
... g +3 = 3(m +3)
Subtracting the first equation from the second, we get ...
... 8 = -2m +34
... 2m = 26 . . . . . add 2m-8
... m = 13
My age now is 13.
