Eight oranges cost $1.00.How much will 5 dozen oranges cost?

Answers

Answer 1

Answer: 1 dollar is to 8
1:8
so 5 dozen
1 dozen=12
5 dozen=12 times 5=60
1:8 and x:60
1/8=x/60
multiply both sides by 60
60/8=x
30/4=15/2=7.5=x
$7.50 is how much you pay

Answer 2

Answer: 5x12=60 60 divided by 8=7.5

Multiply (2.0 ⋅ 10−4) ⋅ (3.1 ⋅ 10−20). Express the answer in scientific notation. 6.2 ⋅ 10−80 6.2 ⋅ 10−24 6.2 ⋅ 1024 6.2 ⋅ 1080

Answers

scientifice notation is
(number less than 10 but greater than or equal to 1) times (10^x)

remember
(ab)(cd)=abcd=(ac)(bd)

and
(x^m)(x^n)=x^(m+n)

so
(2*10^4)(3.1*10^20)=
(2)(10^4)(3.1)(10^20)=
(2*3.1)(10^4*10^20)

(10^4)(10^20)=10^(4+20)=10^(24)

(6.2)(10^24)

whats the answer im so stuck

Answers

The solution to your problem would be that x = 32; or just 32. You did all the heavy lifting!

so it say that x is equal to 32 so you equation must look like this
14+32=45

Which expression shows how 6⋅45 can be rewritten using the distributive property?20⋅6+20⋅5
6⋅40+6⋅5
6⋅40+6
6⋅4+6⋅5

Answers

The correct option will be option B.

An expression is given in the question which is , 6 × 45 .

We have to find an expression using the distributive property.

What is the distributive property of addition ?

The distributive property of addition is given by , A × ( B + C ) = A × B + A × C.

As per the question ;

The expression given is = 6 × 45

or we can also write it as ; 6 × ( 40 + 5 )

Let's assume that here , 6 = a , b = 40 and c = 5 .

Using the distributive property we can re-write it as ;

6 × ( 40 + 5 )

which will be equal to ;

6 × 40 + 6 × 5

∴ 6 × ( 40 + 5 ) = 6 × 40 + 6 × 5

Thus , the correct option is option B.

Simple...

remember A(B+C)=A*B+A*C

You have to have a common factor in both terms..(number)..this number would be 6.

So we know it has to have 6 in your answer.

If we plug n chug..:

20*6+20*5=220

6*40+6*5=270

6*40+6=246

6*4+6*5=54

6*45= 270

This being said, 6*40+6*5 is the choice you need.

Thus, your answer.

write two mixed numbers that have a sum of 3

Answers

1 1/4 + 1 3/4 = 3.

That's because 1/4 + 3/4 = 4/4, which equals 1.

1 + 1 = 2.

Now add the 1 from the 4/4 to the 2, and you get 3.

one would be 1 1/2 + 1 1/2
hope that helps you finish your homework! :)

I am thinking of two numbers. Their sum is 17. One number is 5 more than the other. What are the two numbers?

Answers

17 - 5 = 12
12 divided by 2 is 6
17 - 6 = 11
11 and 6 are the 2 numbers

come up with as many ways to make 17 like for example 9+8=17 that is the answer because 4+5=9 and it says one number is 5 more than the other enjoy!
