Answer: B. 1.85 + x = 5.30
Explanation:
The starting height of the tree was 1.85 meters. To find the number of meters the tree grew, you would subtract the current height from the previous height.
5.30-1.85=x. This equation is the same as 1.85 + x = 5.30 if you switch the 5.30 and x.
Given that triangle <span>STU
is reflected once to map onto
triangle S'T'U'.
Given that triangle STU has
vertices S(8, 6), T(2, 2), U(5, 1).
If vertex T' is at
(2, −2), this means that triangle STU is refrected across the x-axis.
A refrection across the x-axis results in an image that has the same x-value as the pre-image but a y-value that has the opposite sign of the y-value of the pre image.
Thus, a point, say (x, y), refrected over the x-axis will result in an image with coordinate (x, -y)
Therefore, given that the coordinate of S is (8, 6), then the coordinates of vertex S'</span> is (8, -6).

Answer:
For the first one, it is 1150. For the second one, it is 2460.
Step-by-step explanation:
Think of 23 x 50 as (20 x 50) + (3 x 50).
20 x 50 is 1000. 3 x 50 is 150. 1000 + 150 is 1150.
Think of 30 x 82 as (30 x 80) + (30 x 2)
30 x 80 is 2400. 30 x 2 is 60. 2400+60 is 2460.
