1(x + 3) + 3(x - 1) = 20
1(x) + 1(3) + 3(x) - 3(1) = 20
x + 3 + 3x - 3 = 20
x + 3x + 3 - 3 = 20
4x = 20
4 4
x = 5
Area of a parallelogram= base*height
A=14*8
A=112m²
The area of this figure is 112m²
Reflected over the x axis and rotated 180° is your answer
First, note that the horizontal line is the x- axis, and that the figure is reflected over the x- axis.
Next, note that the placement of each point is not exactly identical. Instead, it is flipped. This means that the side is rotated 180°
hope this helps
Answer:
A - 220
B - 205
Step-by-step explanation:
29% of 759 is 220.11, round down so it stays 220.
27% of 759 is 204.93 round up so it becomes 205.
bonus:
44% of 759 is 333.96 round up and it becomes 334.
to check your work, add 220, 205, and 334 and its 759. thats how you can be sure its correct.
hope this helps :)
Given:
total of 224 visitors
older than 18 paid $12
18 and below paid $8
total collection 2,520
Let l be visitors older than 18 and m be visitors 18 and below.
l + m = 224
12l + 8m = 2,520
l = 224 - m
12(224 - m) + 8m = 2520
2688 - 12m + 8m = 2520
-4m = 2520 - 2688
-4m = -168
m = -168/-4
m = 42 number of visitors 18 and below.
l = 224 - m
l = 224 - 42
l = 182 number of visitors older than 18.
12(182) + 8(42) = 2520
2184 + 336 = 2520
2520 = 2520
