Valentin [98]

Julio is x years old and his father is y years old:
y = 4 x
x + y ≥ 55
x + 4 x ≥ 55
An inequality is:
5 x ≥ 55
x ≥ 55 : 5
x ≥ 11

On Friday and Saturday, there were a total of 200 cars in the parking lot of a movie theater. On Friday, 120 cars were in the pa

denpristay [2]

Answer:

(A) 40%

(B) 60%

Step-by-step explanation:

Given:

Total number of cars = 200

Cars in parking lot on Friday = 120

Total number of cars = Total cars on Friday + Total cars on Saturday.

⇒ 200 = 120 + Total cars on Saturday.

⇒ Total cars on Saturday = 200 - 120 = 80

So, 80 cars were in parking lot on Saturday.

(A)

Percentage of cars in parking lot on Friday is given as:

$=\frac{\textrm{Cars in parking lot on Friday}}{\textrm{Total cars parked}}\times 100\\\\=\frac{120}{200}\times 100\\\\=\frac{120}{2}=60\%$

Therefore, 60% of the cars were in the parking lot on Friday.

(B)

Now, since 60% of the cars were parked on Friday, the remaining percent will be on Saturday.

Therefore, percentage of cars in parking lot on Saturday = 100% - 60% = 40%. This can be verified with the same formula used in part (A).

$=\frac{\textrm{Cars in parking lot on Saturday}}{\textrm{Total cars parked}}\times 100\\\\=\frac{80}{200}\times 100\\\\=\frac{80}{2}=40\%$

If f(x) is a linear function, which statement must be true?

Harlamova29_29 [7]

The statements look all false:

A linear function can have constant terms, which is the b coefficient in the expression y=mx+b. For example, y=3x+5 has a constant term 5
A linear function has a x term. In the same example as before, 3x is the x term
The coefficients can be different from 1. In the example before, the x coefficient is 3 and the constant term is 5.
This looks like option b. Maybe there was a typo, and either b or d must be true.
