3/8 of an hour.
If you change 3/4 to 6/8 and then subtract, 6/8-3/8 you would get 3/8.

Tema [17]

Answer:

For mileages higher than 80 miles Company A  will charge less than Company B

Step-by-step explanation:

Hi, to answer this question we have to write an inequality:

Company A charges $111 and allows unlimited mileage.

Company A =111

Company B has an initial fee of $55 and charges an additional $0.70 for every mile driven

Company B = 55+0.70m

Where m is the number of miles.

Company A has to charge less than Company B

a<b

111 < 55+0.70m

Solving for m

111-55 < 0.70 m

56 < 0.70m

56/0.70 < m

80 < m  

For mileages higher than 80 miles Company A will charge less than Company B

Consider the following system of equations: 10 + y = 5x + x2 5x + y = 1 The first equation is an equation of a . The second equa
aleksley [76]

Answer: The first equation is an equation of a parabola. The second equation is an equation of a line.

Explanation:

The first equation is,

10+y=5x+x^2

In this equation the degree of y is 1 and the degree of x is 2. The degree of both variables are not same. Since the coefficients of y and higher degree of x is positive, therefore it is a graph of an upward parabola.

The second equation is,

5x+y=1

In this equation the degree of x is 1 and the degree of y is 1. The degree of both variables are same. Since both variables have same degree which is 1, therefore it is linear equation and it forms a line.

Therefore, the first equation is an equation of a parabola. The second equation is an equation of a line.

Can someone please help me out

Answer:

x = 8, A = 182 units²

Step-by-step explanation:

The perimeter P of a rectangle is calculated as

P = 2l + 2b ( l is the length and b the breadth )

Given P = 66, then

2(7) + 2(3x + 2) = 66 ← distribute and simplify left side

14 + 6x + 4 = 66

6x + 18 = 66 ( subtract 18 from both sides )

6x = 48 ( divide both sides by 6 )

x = 8

Then

3x + 2 = 3(8) + 2 = 24 + 2 = 26, so

A = 7 × 26 = 182 units²
