Answer:
B, x=5
Step-by-step explanation:
Both triangles are similar with a ratio of 22.5/9
so using that an equation can be created like this, 
= 
If simplified, 22.9(x + 4.44) = 23.5(9)
22.5x + 99 = 211.5
22.5x = 112.5
<u><em>x = 5</em></u>
Answer:
If what I think youre saying is correct, then it should be 1/9
Step-by-step explanation:
4/15 + (-7/45)
Multiply both numerator and denominator of 4/15 by 3 so that the denominator becomes 45 to match the other fraction.
12/45 + (-7/45)
As the fraction on the right side is negative, it is taken away from the left fraction, hence:
(12 - 7)/45
Therefore, with simple subtraction,
5/45
Simplify to 1/9
The sequence is not arithmetic
Answer:24
Step by step explanation:
The area of a rectangle is base * altitude, and the perimeter is 2*base + 2*altitude,
base = 10cm and altitude = 7cm
