Answer:
a)3
Step-by-step explanation:
given the triangle abc,if the side ac is 6
the side ac=6
if it is dilated by 50%,then the resulting pre-image is exressed as;
a'c=0.5(6)
a'c=3
hence the side after dilation is 3
Answer:
6 unit cubes
<u>Skills needed: Dimensioning</u>
Step-by-step explanation:
1) Layers are the length x width
The height determines the number of layers. There are 5 layers in this figure as the height is 5.
2) The length x width = 3 x 2 = 6
6 is the answer in this case.
To solve by substitution, you need to fill in the value for either x or y. Since y = x + 5, you already have the y value. It's x + 5. Now you need to find x before you can go any further. So let's take 5x + y = 3 and fill x + 5 in for y.
5x + y = 5
5x + x + 5 = 3
Now solve for x.
5x + x + 5 = 3
6x + 5 = 3
6x = 3 - 5
6x = -2
x = -2/6 or -0.33
Now solve x + 5 for y.
y = x + 5
y = -0.33 + 5
y = 4.67
So x = -0.33 and y = 4.67
