Answer:
n=7 d=8
Step-by-step explanation:
n+d=15 d=15-n
0.05n+0.1(15-n)=1.15
0.05n-0.1n+1.5=1.15
-0.05n=-0.35
n=7 d=8
Answer:
<u>-5 ± √5² - 4 · 1 · 4</u>
2 · 1
Step-by-step explanation:
ax²+bx+c=0 (quadratic equation)
x=<u> -b ± √b² - 4ac</u>
2a
a= 1
b= 5
c= 4
-<u>5 ± √5² - 4 · 1 · 4</u>
2 · 1
Answer:
A
Step-by-step explanation:
Vertical angles are angles that are formed by 2 lines and are directly accross from each other. They do not share a ray, however they are always the same number of degrees.
so then the answer would be A, ∠ERT and ∠MRC since they are directly across from each other.
If you would like to solve the equation 10 * x - 12 = 48 - 2 * x, you can calculate this using the following steps:
10 * x - 12 = 48 - 2 * x
10 * x + 2 * x = 48 + 12
12 * x = 60 /12
x = 60 / 12
x = 5
The correct result is 5.
