Answer:
$ 260.25
Step-by-step explanation:
$ 347 multiply by 25% or 0.25
You get $ 86.75
Take $347 - $86.75 = $ 260.25
Answer:
The solution of a system of linear equations is:
D. The values of the variables that satisfy both equations.
Answer: 1: 34 units 2: 24.5
Step-by-step explanation:
For figure 1, just split the area into squares and triangles and find the area of each. If you split figure 1 into 1 square and 3 triangles you get...
4x4= 16
(4x3)/2= 6
(4x4)/2= 8
(4x2)/2= 3
16+6+8+3 = 34
You do the same for figure 2, but use 4 triangles and 1 tiny square
1x1= 1
(4x3)/2= 6
(3x3)/2= 4.5
(4x4)/2= 8
(5x5)/2= 5
1+6+4.5+8+5= 24.5
You shouldn't need to worry about negative numbers because you are looking at the area
The answer would be -81t^2+16
