Answer:
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees. This means that
Angle A + Angle B + Angle C = 180 degrees
Looking at the triangle,
Angle A = (15x + 10) degrees
Angle B = (15x - 10) degrees
Angle C = (3x + 15) degrees
Therefore,
15x + 10 + 15x - 10 + 3x + 15 = 180
15x + 15x + 3x + 10 - 10 + 15 = 180
33x + 15 = 180
Subtracting 15 from the left hand side and the right hand side of the equation, it becomes
33x + 15 - 15 = 180 - 15
33x = 165
Dividing the left hand side and the right hand side of the equation by 33, it becomes
33x/33 = 165/33
x = 5
Angle A = 15 × 5 + 10 = 85 degrees
Answer:
1
Step-by-step explanation:
The coefficient is the number in front of the variable. Since there is not a number written, there is an implied 1
x+4
1x+4
The coefficient is 1
Answer:
8x+64≥150
Step-by-step explanation:
$8 an hour is your variable, and 64 is added already. She needs at least $150, so that's greater than or equal to 150.
Answer:
Option C is correct.
Step-by-step explanation:
The third one is right because the null hypothesis implies with all therapies, identical percent of kids suffer, and that simply means that there really is no distinction in drug therapies.
So, it defines the probabilities among both treated groups unless there was really no variation among drug therapies.
Due to the following reasons it describes that the following option is correct according to the statement.
