11z ➗ 16 ➕ 7z ➗ 8 = 5 ➗ 16
x 8 x 8
11z ➗ 16 ➕ 7z = 5 ➗ 16 x 8
x 16 x 16
11z ➕ 7z = 5 x 8
18z = 40
➗ 18. ➗ 18
z=40 ➗ 18
z = 2.2

This is the way I was taught to do it. if the answer is incorrect, at least you can use my work as an example to go off of.

(what you do to one side you do to the other. I'm using my phone and everything condensed, I apologize)

What is the greatest number of cubes with a side of 1.5cm that can fit in the box with dimensions 16cm ×5cm ×12cm? Please help m

Vitek1552 [10]

Answer: 284 cubes.

Step-by-step explanation:

By definition, the volume of a rectangular prism can be calculated by multiplying its dimensions.

Knowing that the dimensions of this box are $16cm*5cm*12cm$ , we get that the volume of the box is:

$V_{box}=16cm *5cm *12cm=960cm^3$

The formula for calculate the volume of a cube is:

$V=s^3$

Where "s" is the lenght of a side.

Kwnowing that the a cube has a side of 1.5 cm, we get that the volume of one cube is:

$V_{cube}=(0.5cm)^3=3.375cm^3$

Dividing $V_{box}$ by $V_{cube}$ we get the greatest number of cubes that can fit in the box:

$number\ of\ cubes=\frac{960cm^3}{3.375cm^3}=284$

Brandon is running errands for his mother.

LiRa [457]

Answer:

As it is clear that adding 1/4 + 2/3 will bring 11/12. Therefore, Brandon is correct when he claims that he walks a total of 11/12 mile if he goes from his house to the library to the grocery store.

Step-by-step explanation:

As Brandon is

1/4 mile from his house to the library

2/3 mile from the library to the grocery store

Brandon claims that he walked a total of 11/12 mile if he goes from his house to the library to the grocery store

So, adding 1/4 + 2/3 would determine whether he is right or wrong.

Thus, considering the expression

$\frac{1}{4}+\frac{2}{3}$

$\mathrm{Least\:Common\:Multiplier\:of\:}4,\:3:\quad 12$

$Adjust\:Fractions\:based\:on\:the\:LCM$

$\frac{1}{4}+\frac{2}{3}=\frac{3}{12}+\frac{8}{12}$

$=\frac{3+8}{12}$

$=\frac{11}{12}$

As it is clear that adding 1/4 + 2/3 will bring 11/12. Therefore, Brandon is correct when he claims that he walks a total of 11/12 mile if he goes from his house to the library to the grocery store.

The sum of three consecutive

TEA [102]

Answer:

Step-by-step explanation:

let the integers be x,x+1,x+2

x+x+1+x+2≤951

3x≤951-3

3x≤948

x≤316

greatest value of x=316

x+1=316+1=317

x+2=316+2=318

so integers are 316,317,318

Greatest inter=318
