Answer:
The x-intercept of the line is 4 minutes.
That 4 minutes gives the time when Shari will reach her home.
Step-by-step explanation:
The line 6x - 3y = 24......... (1), represents Shari's distance from home, y in blocks, on her run across town over time, x, in minutes.
So, at y = 0, from the above equation (1), we get 6x - 0 = 24, ⇒ x = 4.
Therefore, the x-intercept of the line (1) is 4 minutes.
That 4 minutes gives the time when Shari will reach her home and the distance between her and her home is zero blocks. (Answer)
0.10r + 0.20b = 24
3r = b + 20....b = 3r - 20
0.10r + 0.20(3r - 20) = 24
0.10r + 0.60r - 4 = 24
0.70r = 24 + 4
0.70r = 28
r = 28/0.70
r = 40 <=== there are 40 reds
0.10r + 0.20b = 24
0.10(40) + 0.20b = 24
4 + 0.20b = 24
0.20b = 24 - 4
0.20b = 20
b = 20/0.20
b = 100 <=== there are 100 blues
To find the expression that is equivalent to -4.5-6.2y we will rearrange all the given options to find the equivalent expression.
The expression that is equal to -4.5-6.2y is -6.2y-4.5.
Given options to us
- –6.2y – 4.5
- –6.2y + 4.5
- 6.2y – 4.5
- 6.2y + 4.5
<h3>Which expression is equivalent to –4.5 – 6.2y?</h3>
We need to find an expression that is equal to -4.5-6.2y.
Therefore, we will arrange each of the equations and then compare it our equation,
A. –6.2y – 4.5
-4.5 -6.2y
Since after arranging the expression it matches our equation this is the expression that is equivalent to our equation.
B. –6.2y + 4.5
4.5 - 6.2 y
Since even after arranging the expression it does not match our equation this is the expression is not equivalent to our equation.
C. 6.2y – 4.5
-4.5 + 6.2 y
Since even after arranging the expression it does not match our equation this is the expression is not equivalent to our equation.
D. 6.2y + 4.5
4.5 + 6.2y
Since even after arranging the expression it does not match our equation this is the expression is not equivalent to our equation.
Hence, the expression that is equal to -4.5-6.2y is -6.2y-4.5.
