Answer: Yes
Step-by-step explanation:
2x+8y=6
-8y -8y
2x = -2y
Divide by two so x will be by itself, so the answer will be -1y.
5x+20y=2
-20y -20y
5x = -18y
Divide by 5 so x will be by itself, so the answer will be -3y.
Answer:
1056
Step-by-step explanation:
Find the area of each square and add them to find the area of the rectangle
The area of a square = side * side
The areas are:
1*1= 1
4*4 = 16
7*7 = 49
8*8 = 64
9*9 = 81
10*10 = 100
14*14 = 196
15*15 = 225
18*18 = 324
The sum of the areas =
324+225+196+100+81+64+49+16+1
= 1056 units ^2
Answer:
D
Step-by-step explanation:
We can safely assume we are dealing with an arithmetic scale because the type of scale isn't mentioned anywhere. The more right a point is on the scale, the higher its value is. We are given two points of the scale: 3 and 4. Because the scale is arithmetic, we know that 3.8 must lie on 4/5s of the length between 3 and 4 to the right of 3, which is exactly where point D is.
4 x 2 over 2
8/2 + 1/2 = 9/2
3 x 4 over 4
12/4 +1/4 = 13/4
Top times top over bottom times bottom.
9 x 13 over 2 x 4
117 / 8
14 and 5/8
