Answer:

Surface area = 90 cm²

Step-by-step explanation:

Given net of the rectangular prism shows the dimensions as,

Length = 5 cm

Width = 5 cm

Height = 2 cm

`Expression for the surface area of a rectangular prism = 2(lb + bh + hl)

Here, l = length

w = width

h = height

By substituting the values in the expression,

Surface area = 2(5×2 + 5×2 + 5×5)

= 2(10 + 10 + 25)

= 90 cm²

11 x minus 3 y = negative 17. Negative 4 x + 3 y = negative 18. Negative 7 x = negative 35 Negative 7 x = 35 7 x = negative 35 7

posledela

Answer:

7 x = -35

Step-by-step explanation:

Which equation results from adding the equations in this system? 11 x minus 3 y = -17. Negative 4 x + 3 y = - 18.

- 7 x = negative 35

- 7 x = 35

7 x = negative 35

7 x = 35

In this problem we need to add the equations below i.e.

11x-3y = -17 and -4x+3y=-18

Adding both equations,

11x-3y+(-4x)+3y = -17+(-18)

7x= -35

7 x = negative 35

Hence, the correct option is (c).

Monica has 4 boxes to place in an empty carton the mass of each box is 4.5 kilograms the mass of the carton is 500 grams what is

Anastaziya [24]

Total mass in grams of the carton and the 4 boxes is 18.5 kg .

<u>Step-by-step explanation:</u>

Here we have , Monica has 4 boxes to place in an empty carton the mass of each box is 4.5 kilograms the mass of the carton is 500 grams.

We need to find the total mass in grams of the carton and the 4 boxes . Let's find out:

Total mass = Mass of 4 boxes + Mass of empty carton

Mass of 1 box = 4.5 kg

Mass of 4 boxes = $4.5(4) = 18kg$

Mass of 4 boxes = $18kg$

Mass of empty carton = $500g$ = 0.5 kg

⇒ Total mass = Mass of 4 boxes + Mass of empty carton

⇒ Total mass = $18 + 0.5$

⇒ Total mass = $18.5\ kg$

Therefore, total mass in grams of the carton and the 4 boxes is 18.5 kg.
