Answer:

4x-5y=2, 24x-47y=22

Step-by-step explanation:

I mean I would write out all the steps for the answers if I wasn't feeling lazy.

4x-5y=2

10x-21y=10

x=-\frac{4}{17},y=-\frac{10}{17}

Here you can have the answers:

4x-5y=2

3x-y=4

x=\frac{18}{11} , y=\frac{10}{11}

4x-5y=2

24x-47y=22

x=-\frac{4}{17},y=-\frac{10}{17}

4x-5y=2

10x+3y=15

x=\frac{81}{62},y=\frac{20}{31}

4x-5y=2

14x+26y=12

x=\frac{56}{87},y=\frac{10}{87}

It seems that 4x-5y=2, 24x-47y=22 is the correct answer.

Consider the rectangular prism below.
Radda [10]

Answer:

Option D

Step-by-step explanation:

Formula for the surface area of rectangular prism = 2(lb + bh + hl)

Here, l = Length of the prism

b = Width  

h = Height

If l = 25 cm, b = 12 cm and h = 20 cm

Surface area of the rectangular prism = 2(25×12 + 12×20 + 20×25) cm²

Therefore, Option D will be the correct option.

Ibrahim wants to give each of his six friends 1 2/3 candy bars. How many candy bars does he need to buy?
denis-greek [22]

Answer:

10 candy bars

Step-by-step explanation:

Since each of his friends needs a candy bar, you need to multiply 6 and 1 ⅔ together.

First, convert 1 ⅔ into an improper fraction: this gives us ⁵⁄₃.

Next, multiply ⁶⁄₁ and ⁵⁄₃ together. To do this, you can visualize 6 as ⁶⁄₁ (which is the same thing). Now you have ⁶⁄₁ x ⁵⁄₃.

<u>Simplify:</u>

The 6 in the numerator and the 3 in the denominator cancel out. This gives us ²⁄₁ x ⁵⁄₁ , which is 2 x 5.

2 x 5 = 10
