160 - x = 51*2
160 -x = 102
x = 160-102
x = 58
Answer:
<em>d</em> = 24.63
Step-by-step explanation:
82.53 - (21.7 + 17.3 + 18.9) =
24.63
Answer:
Step-by-step explanation:
Let c be the number.
We are asked to write an expression for given verbal description.
7 times the number c would be 
.
Two less than seven times a number means 2 subtracted from .
Two less than seven times a number c would be .
Therefore, our required expression would be .
For the first problem, the triangle is equilateral. This means that all three sides will have the same length. So you need to find a value for x that makes all three of those statements equivalent. I believe you could find it using a system of equations... but it’s been a while so don’t quote me on that.
For the second, ce and de are equal. Set them equal to each other and solve for x. Then plug that x value back into the side lengths.
