Answer:
2/3
Step-by-step explanation:
5 black
3 green (not black)
3 blue (not black)
4 yellow (not black)
there are 5 black and 10 not black out of a total of 15 marbles.
there are 10/15 that are not black. Reduced 2/3.
D) the total charge before applying the sales tax
It’s the amount after you apply the $5 coupon, but before you apply the sales tax, which is 8%
Answer:
3x3x3x3x3x3x3x3
Step-by-step explanation:
Or three eight times :)
The minimum and maximum values are the extreme ends of the spectrum of range for wind speed. The base wind speed must be somewhere between the 2 values. It is called the mean.
Mean = (74 + 95)/2 = 84.5
Then, you find the difference of the values to the mean:
84.5 - 74 = 10.5
95 - 84.5 = 10.5
Thus, the absolute value equation for V will be:
V = |84.5 +/- 10.5|
The solution of the system of equations is (-1 , -1)
Step-by-step explanation:
To solve the system of linear equations by substitution method
- Use one of the two equation to find one variable in terms of the other terms
- Substitute this variable in the second equation to find an equation of one variable
- Solve the equation to find the this variable
- Find the first variable using the substitution equation
∵ x + y = -2 ⇒ (1)
∵ y = 4x + 3 ⇒ (2)
- Substitute y in equation (1) by equation (2)
∴ x + (4x + 3) = -2
- Add like terms
∴ (x + 4x) + 3 = -2
∴ 5x + 3 = -2
- Subtract 3 from both sides
∴ 5x = -5
- Divide both sides by 5
∴ x = -1
- Substitute the value of x by -1 in equation (20 to find y
∴ y = 4(-1) + 3
∴ y = -4 + 3
∴ y = -1
The solution of the system of equations is (-1 , -1)
