it is 90 is the answer i think
You answer is B you times both the top and the bottom by 3
20-23 red marbles makes the most sense
Answer: x ≥ -1
<u>Step-by-step explanation:</u>
4(2x - 3) ≥ 4(x - 4)
8x - 12 ≥ 4x - 16 <em>distributed 4 into 2x - 3</em>
4x - 12 ≥ -16 <em>subtracted 4x from both sides</em>
4x ≥ -4 <em>added 12 to both sides</em>
x ≥ -1 <em>divided both sides by 4</em>

Answer:
small number = -3
large number = 12
Step-by-step explanation:
Suppose two numbers are x and y
smaller number = x
larger number = y
Given that,
The difference of two numbers is 15
<h2>Equation 1</h2><h3>y - x = 15</h3>
Five times the smaller is the same as 9 less than twice the larger.
<h2>Equation 2</h2><h3>5x = 9 - 2y</h3>
Solve them
-x = 15 - y
x = y -15
put value of x in equation 2
5(y - 15) = 9 - 2y
-75 + 5y = 9 - 2y
-75 - 9 = -2y - 5y
-84 = -7y
y = 84/7
y = 12
x = 12 - 15
x = -3
