1. 50 + 20x = 240
2. 85% so more than 75%
3. 25.9% so about 26%

We can find the value of x through a proportion. Since these two triangles are similar, their sides are in proportion.
4 is to 12 as 5 is to x
Remember to say 12, not 8! 8 is only part of the whole side. We can also simplify 4 is to 12 to 1 is to 3.
1/3 = 5/x
Cross multiply
x = 15
Hope this helps!
12. The inverse relation has the x- and y-values swapped.
The appropriate choice is ...
D. (13, 5)
She will make 9 rows because 27 + 27 = 54 and divided by 6 =9
Answer:
Step-by-step explanation:
Here we need to find the x for the given equation so we can use the concept of the quadratic formula to solve .
comparing the given equation with an standard quadratic equation we get
a=1
b=6
c=3
so applying the quadratic formula we get


which can be further simplified to get
x=-5.45 or x=-0.55
so correct option is <em>A</em>
