Y= 17 I think ........................
(2 x 3.95) + (3 x 4.25) + (1 x 5.99) + ((2 x 3.95) + (3 x 4.25) + (1 x 5.99)) x 0.20
= 26.64 - 5.32
= 21.32
Answer:
0.5
Step-by-step explanation:
Total space in the parking lot = 10
number of cars parked = p
number of empty parking spaces = e
There are the same number of cars parked in the parking lot as there are empty parking spaces.
This means,
Number of parked cars = number of empty parking spaces
p = e
If the number of parked cars and number of empty parking spaces = 10
p + e = 10
If p = 5
Then,
p + e = 10
5 + 5 = 10
Write a decimal to show the part of the parking lot that has empty parking spaces.
Empty parking space/total parking space
= 5/10
= 1/2
= 0.5
part of the parking lot that has empty parking spaces = 0.5
Answer:
False.
Step-by-step explanation:
A complementary angle is an angle where two seperate angles add together for a 90 degree angle. They usually share a side, but not always.
Answer:
x = - 4, x = 7
Step-by-step explanation:
Given
x(x - 3) = 28 ← distribute left side
x² - 3x = 28 ← subtract 28 from both sides
x² - 3x - 28 = 0 ← in standard form
To factor the quadratic
Consider the factors of the constant term (- 28) which sum to give the coefficient of the x- term (- 3)
The factors are - 7 and + 4, since
- 7 × 4 = - 28 and - 7 + 4 = - 3, hence
(x - 7)(x + 4) = 0
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 4 = 0 ⇒ x = - 4
