Answer:
0.47/94=200?
Step-by-step explanation:
<span>All the angles of a triangle add up to 180 degrees.
Since two of the angles are the same, we can write:
2A+B=180
Where 2A accounts for the two angles that are the same.
We are given the relation:
B=A+30
We can plug this into our first equation:
2A+A+30=180
</span><span>
Combine like terms and move the 30 to the other side:
3A=150
Divide both sides by 3:
A=50
We can solve for B by plugging A back into our relation:
B=50+30
B=80
To check: 80+50+50 so we are correct.</span>
Answer: a conditional statement.
Step-by-step explanation:
We can write an algebra formula so let the number be Y
Y x 75% = 15
Y = 15/75% (aka 15/0.75)
therefore Y = 20
Answer:
-3 is the other solution.
Step-by-step explanation:
As, is One of the solutions of the equations , So, it should satisfy the equation.
Putting in equation 5 + bx + 12 = 0 ,
We get,
5×× + b× + 12 = 0.
5× + + 12 = 0.
After solving , 16 - 4b + 60 = 0.
4b = 76
b = 19.
So, the equation is 5 + 19x + 12 = 0.
After factorizing , 5 + 15x + 4x + 12 = 0.
5x(x+3) + 4(x+3) = 0
(5x+4)(x+3) = 0
Clearly the roots of the equation are -3 and .
So, the other solution is -3.
