Answer:
x = 14
Step-by-step explanation:
10x-30+5x = 180
Combine like terms
* 15x-30 = 180
Add 30 from both sides
* 15x 30+-30 = 180+30
Divide 15 both sides
* 15x/15x = 210/15x
x = 14

JJ withdraws $20 from his bank account every week for lunch. Suppose he does not make any additional deposits or withdrawals. What integer represents the change in value of JJ's bank account after nine weeks?
Answer:
-118
Step-by-step explanation:
Since he is withdrawing, the value of 20 will be negative.
And if he is withdrawing $20 over nine weeks, then it is a multiplication problem.
So,
-20 x 9 = -118

What is the solution to the equation? ^5 /x+ 7= -2
Answer:
x=19/2
Step-by-step explanation:
5/x+7=-2
5=-2(x+7)
5=-2x-14
5+14=-2x
19=-2x
Therefore
2x=-19
x=19/2
Write an equation. A number is doubled, then 9 is added. The result is 23.
Answer:
2n + 9 = 23
Step-by-step explanation:
let the number be n then double the number is 2n and adding 9 gives
2n + 9 ( the result is 23 ) , so
2n + 9 = 23 ← is the equation modelling the statement

Solve 5x + 2 = 22
Solve 2x-5=7
Solve 2x+5=12
Answer:
x = 4
x = 6
x = 7/2
Step-by-step explanation:
Solve 5x + 2 = 22:
5x+2-2=22-2 (subtract 2 from both sides)
5x=20
x=4
Solve 2x-5=7
2x-5+5=7+5 (add 5 to both sides)
2x=12
x=6
Solve 2x+5=12
2x+5-5=12-5 (subtract 5 from both sides)
2x=7
x= 7/2
=> 5x + 2 = 22
=> 5x = 22 – 2
=> 5x = 20
=> x = 20/5
=> x = 4
Solve 2x-5=7=> 2x - 5 = 7
=> 2x = 7+5
=> 2x = 12
=> x = 12/2
=> x = 6
Solve 2x+5=12=> 2x + 5 = 12
=> 2x = 12-5
=> 2x = 7
=> x = 7/2

Answer:
Step-by-step explanation:
g(-4) = 4 , x < -2
g(-2) = (x - 1)² ; -2≤x< 1
= (-2-1)²
= (-3)²
g(-2) = 9
g(0) = (x -1)² ; -2 ≤ x < 1
= (0 -1)²
= (-1)²

Answer:
x = 10°
Step-by-step explanation:
m∠DCR is an exterior angle of the triangle DCE
Solving For Exterior Angles:To find the value of an exterior angle, we must sum up the two opposite (corresponding) angles inside the triangle
In this case, 2x + 7 and 26 are the corresponding angles
Solve:6x - 7 = 2x + 7 + 26
4x - 7 = 7 + 26
4x = 14 + 26
4x = 40
x = 10°
Your answer : x = 10°-Chetan K

The GCF of two numbers is 3 and the LCM is 180. If the one of the number is 45, what is the other number?
Answer:
45
Step-by-step explanation:
45 = 3*3*5
180 = 2*2*3*3*5 <---- so the other number had to contain a factor of 2*2 or 4
also, let the other number has to be of the form 3k and it must contain a factor of 4, how about 12 ?
check: lcf of 12 and 45 is 3,
the lcm of 12 and 45 is ...
12 = 2*2*3
45 = 3*3*5
so we need: 2*2*3*3*5 = 180
