Answer:
x = 7.5
Step-by-step explanation:
Since we see that sides AD and DC are equal, as well as sides BE and EC, we can use this information to conclude that the value of 2x-7 is equal to double the value of DE.
2x - 7 = 4(2)
2x - 7 = 8
2x - 7 + 7 = 8 + 7
2x = 15
x = 7.5
Answer:
100 in^2
Step-by-step explanation:
Solve Area first:
5x8
= 40
Multiply by 2.5 (Enlarge)
40 x 2.5
= 100
1. Change the fraction to a decimal 0.625
2.Line up the decimals
incorrect correct
-0.615 -0.615
0.625 0.62
0.62 0.625
For this question you need to use what's called point-slope form. It's named this way because you can use it if you have both the slope and a point at which the line passes through. That said, the equation is as follows:
y - y1 = m(x - x1)
Both y1 and x1 represent the y and x coordinates you are given in the question. Also, m represents the slope of the line that you are given. Knowing this, our equation now looks like this:
y - 4 = -0.5(x - (-5))
And now simplify:
y - 4 = -0.5(x + 5)
y - 4 = -0.5x - 2.5
y = -0.5x + 1.5
Answer:
n=14
Step-by-step explanation:
-6=(n/-14)-5
-6+5 = n/-14
-1= n/-14
cross multiplication and striking of negative sign from both side.
n=14
