Answer:
x= 28 and y=21
Step-by-step explanation:
x - y = 7
x + y = 49
add the two equation and the y's will cancel out
2x = 56 divide by 2
x = 28
replace 28 for x in the first equation and solve for y
28 - y = 7
y = 21

There are approximately, 18 men for 2 women in the armed forces. In a group of 90 military personnel, how many would you expect to be women?
Answer: 10 women
Step-by-step explanation:
From the question, we are informed that there are 18 men for 2 women in the armed forces. This gives us a fraction of: 2/18 = 1/9
In a group of 90 military personnel, the number that'll be expected to be women will be:
= 1/9 × 90
= 10 women
Solve 10 ax + 11 ax = 12ax +45 for x. Assume a ≠0.
A. x= 5a
B. X= 5/a
c. x = 1/9a
D. x = 9a
Answer:
Pretty sure it's B.
Step-by-step explanation:
The solution of given equation 10 ax + 11 ax = 12ax +45 is x = 5/a.
The correct answer is an option (B)
What is an equation?"It is a statement which consists of equal symbol between two mathematical expressions."
For given example,
We have been given an equation 10 ax + 11 ax = 12ax + 45
We need to solve given equation for x.
Assuming a ≠ 0,
⇒ 10 ax + 11 ax = 12ax +45
⇒ (10 + 11) ax = 12 ax + 45 ...............(Separate out common terms)
⇒ 21 ax = 12 ax + 45
⇒ 21 ax - 12 ax = 12ax + 45 -12 ax ...........(Subtract 12 ax from each side)
⇒ (21 - 12) ax = 45 ...............(Separate out common terms)
⇒ 9 ax = 45
⇒ 9ax/9a = 45/9a ..............(Divide both the sides by 9a)
⇒ x = 5/a
Therefore, the solution of given equation 10 ax + 11 ax = 12ax +45 is x = 5/a.
The correct answer is an option (B)

infinitely many solutions? 8(3x - 6) = 6(4x + 8) *
One solution
No solution
Infinitely many solutions
Answer:
no solution
Step-by-step explanation:
Given
8(3x - 6) = 6(4x + 8) ← distribute both sides
24x - 48 = 24x + 48 ( add 48 to both sides )
24x = 24x + 96 ( subtract 24x from both sides )
0 = 96 ← not possible
This indicates the equation has no solution
