Answer:
C
Step-by-step explanation:
5.1 + 2y + 1.2 = -2 + 2y + 8.3 ( subtract 2y on each side)
5.1 + 1.2 = -2 + 8.3 ( collect like terms)
6.3 = 6.3
If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.
Answer:
C. 5.1 + 2y + 1.2 = -2 + 2y + 8.3
Step-by-step explanation:
-6.8 + 3y + 2.4 = 4.3 - 3y **SOLVE FOR y
-4.4 + 3y = 4.3 - 3y
3y +3y = 4.3 + 4.4
6y = 8.7
8.7 DIVIDED BY 6
y = 1.45 THEREFORE, only one solution
1/3y + 2.5 - 2/3y = 1.2 ** TRANSFORM DECIMALS TO FRACTIONS!
1/3y + 5/2 - 2/3y = 6/5 --> multiply both sides by 30
10y + 75 - 20y = 36 --> collect like terms
-10y = 36 - 75
-10y = -39
y = 3.9 or 39/10 one solution
5.1 + 2y + 1.2 = -2 + 2y + 8.3
5.1 +1.2 = -2 + 8.3 ***2y crosses out as their the same!!
6.3 = 6.3 a REAL solution; infinity many
2/5y = 2.3 + 3/2y
2/5y = 23/10 + 3/2y
4y = 23 + 15y
4y - 15y = 23
-11y = 23
y = -2.09 or -23/11 one solution
Hope I helped!!!

Runner 3 does not get a head start. He runs 750 meters every 3 minutes. Write an equation to represent Runner 3’s distance y for x minutes.
A. y=3x+250
B. 750x+3
C. 250x+3
D. 250x
Answer:
I think it is D!
Step-by-step explanation:
I'm not exactly for sure so if I'm wrong I'm sorry! But when writing an equation they don't have + or - and my conclusion is if you divide 750 by 3 it equal out to be 250 per minute. But I'm not for sure:(
Simplify the expression.
x+3+5x

What is the cost of making one burrito?
Answer:
$4.27
Step-by-step explanation:
Answer:
The cost of making one burrito is $2.50
By selling 100 burritos the restaurant would have profits of $550
Step-by-step explanation:
Since the cost of meat is $1.50 and the cost of other ingredients is $1 you add both of these together to get the total cost of making a burrito which is $2.50
In order to calculate profits you subtract 2.5 from 8 (which is 5.5) because it takes $2.5 to make a burrito
To find the total profits of selling 100 burritos you do 5.5 x 100= 550

Please help asap i need help and explain how do u count this without a ruler
Answer:
you would take your index finger and your thumb and put them toward the eraser and move your fingers and the answer is 9 or 13 if you needed help with that
Step-by-step explanation:
Answer:
13 cm
Step-by-step explanation:
The good news is that you don't need a ruler!
First, you see that the eraser is approximately 5 cm in length, so you must your mind to mentally picture the eraser beside it. You end up with 10 cm. Then, you see that there is more space left on the stick. You know that another complete eraser will not fill up that space. So, you must ask yourself: What is larger than 9 cm, but smaller than 15 cm? The answer is 13 cm!

Answer: these are in "slope-intercept form" y = mx + b
m is the slope. b is the y-intercept
Start with the y- intercept, the "constant" on the right side of the equation. Plot a point there on the y-axis. Then use the slope to plot another point or two to find our where to draw the line. If there is no number for m, it is an implied 1. That means from your first point, go up 1 then 1 to the right to plot the next point
Step-by-step explanation:
When the slope is a fraction, use the denominator to find out how far to go to the right.
If the slope is negative, move down first then to the right to plot the next point.
