Answer:
24/4
Step-by-step explanation:
all you have to do is multiply 4x6=24
Answer:
infinite number of solutions
Step-by-step explanation:
Work with the second equation. Subtract 8x from both sides.
- 4y + 8x - 8x = -8x - 12 Collect like terms.
-4y = - 8x - 12 Divide by - 4
-4y/-4 = - 8x/-4 - 12/-4
y = 2x + 3
That is exactly the same line as the first given. There is an infinite number of solutions.
Answer:
Step-by-step explanation:
Solve for h, means that you have <em>to clear</em> h.
We have the expression 
We can divide both sides of the equation in (a+b):
Now divide again both sides of the equation in 12.
Observation: Distributive property: 
, then: 
The answer is:
Answer:
25.2
Step-by-step explanation:
Secant-Tangent Formula:
(whole secant) x (external part) = (tangent)^2
(41+12) * 12 = x^2
( 53) * 12 = x^2
636= x^2
Taking the square root of each side
sqrt(636) = x
25.2=x
Answer:
5 students
Step-by-step explanation:
The total no. of students in the class is 25=100%
20% of this 25 students are in a club;
Therefore, 25 = 100%
? = 20%
=(20×25)/100
=5 students.
