Hello!
3 + 2 = 5
125 divided by 5 = 25
25 x 3:2 = 2
25 x 2 = 50
Answer: All Real Number
Step-by-step explanation:
This is a system of equation, and generally, there are three ways to solve:
- elimination
- substitution
- augmented matrix
Here, we are going to use elimination

Given
-2x-y=1
-6x=3y+3
Put them in the same order
-2x-y=1
-6x-3y=3
Multiply 3 on both sides for the first equation
-6x-3y=3
-6x-3y=3
We subtract the first equation from the second equation
0=0
The answer will be All Real Numbers, which means any real number will fit this equation. In the graphing method, these two equations will overlap each other.
Hope this helps!! :)

Answer:
<em>The correct option is: B</em>
Step-by-step explanation:
The x-axis is labeled Time driving, and the y-axis is labeled Distance driven.
Segment B is a <u>horizontal line</u> from x equals 0.5 until 1.75.
So, the value of 
is constant in the interval 
to 
is 0.
Thus, the distance traveled in the time interval 0.5 to 1.75 will be 0, which means the car was in the same position in that time interval.
So, the interval B on the graph indicates she is stuck in a traffic jam.
Answer: Josie has 25 nickels and 9 quarters.
Step-by-step explanation:
Let x = Number of Nickels , y =Number of Quarters.
Then x+y = 34
⇒ y=34-x (i)
$3.50 = 350 cents [ $1 = 100 cents ]
Then, 5x+25y= 350 (ii) [Since 1 nickel = 5 cents , 1 quarter = 25 cents]
Substitute value of y from (i)
5x+25 (34-x)=350
⇒ 5x + 850 - 25x =350
⇒ -20x= 350-850
⇒ -20x= -500
⇒ x = 25 [divide both sides by -20]
Put this in (i) , we get y= 34-25=9
Therefore, Josie has 25 nickels and 9 quarters.
