Mathematics
1 answer:
Ainat [17]3 years ago
4 0

Answer:

- True

- True

- False

- True

Step-by-step explanation:

- Subtracting the equation will get rid of y variable therefore it's a correct and logical first step to solve the system

- The solution is indeed (-3, -3) as if we substitute these values in both equation, the equation will be correct and valid.

-2(-3)+(-3)=3 (Correct)

3(-3)+2(-3)=-15 (Correct)

- We have already determined the logical first step. Multiply by -2 will not get rid of any of the variables. Therefore, this is false.

- The solution can be written as one value since x = y = -3. Therefore, this statement is true.

A right triangle ABC with height AB labeled 3 units and base BC labeled 5 units is shown. The area of the triangle above will eq
zhenek [66]

Answer:

Step-by-step explanation:

Answer:

w=3

Step-by-step explanation:

The area of the triangle is given by

A = 1/2 bh

the base is 5 and the height is 3

A = 1/2 (3) * 5 = 15/2  units ^2

The area of a rectangle is

A = l*w

A = 5w

The area of the triangle = 1/2 the area of the rectangle

15/2 = 1/2 *5w

15/2 = 5/2 w

Multiply each side by 2/5 to isolate w

2/5 * 15/2 = 2/5 *5/2 w

3 =w

I need help on this..... can anyone help me?
galben [10]

Answer and step-by-step explanation:

Tim Carter money made:

First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)

Because he works for 50 hours so next 10 hours (50-40) = 10 * (1.5*5.15)

= 10* 7.725 = $77.25

Total money he made:

= 206 + 77.25 = $283.25

Jeese Jones money amde:

First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)

Because he works for 47.5 hours so next 7.5 hours (47.5-40) = 7.5 * (1.5*5.15)

= 7.5 *7.725 = $57.9375

Total money Jeese Jones made:

= 206 + 57.9375 = $263.9375

Barbara Burns money made:

First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)

Because Barbara Burns works for 44 hours so next 4 hours (44-40) = 4 * (1.5*5.15)

= 4* 7.725 = $30.9

Total money Barbara Burns made:

= 206 + 30.9 = $236.9

Hope this help you :3
