Answer:
X = 6°
Step-by-step explanation:
In a set of parallel lines, the opposite angles and corresponding angles are similar. Since the opposite angle of 110° is the corresponding angle of 19x - 4, you can conclude that 19x - 4 = 110° ⇒ 19x = 114° ⇒ x = 6°.
Answer:
option D. Neither
Step-by-step explanation:
y-4=7(x-6)
using (5,4):
4-4=7(5-6)
0=7(-1)
0=-7
using (6,5):
5-4=7(6-6)
1=7(0)
1=0
so option D is the answer
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
<span> x^2-14*x+31-(63)=0 </span><span>x = 16
</span>
The first thing we are going to do for this case is define variables.
We have then:
x = Number of boys
y = Number of girls
We now write the system of equations:
x / y = 11/9
x = y + 124
Solving the system we have:
x = 682
y = 558
The number of students is:
x + y = 682 + 558 = 1240
Answer:
the total students in the school is:
1240 students
