How many thirds are in 4/5? complete an area model and give the quotient.

1 answer:

3 0

There are 24 sixth-sized pieces in 4. and we can see that there are 4 wholes with 6 sixths in each whole, so there are 4\times 6 = 24 sixths in 4. How many two-thirds are in 2? Each whole yields a two-thirds and one half of another two-thirds, therefore 3 sets of two-thirds can be made.

Answer:

A system has infinitely many solutions when it is consistent and the number of variables is more than the number of nonzero rows in the rref of the matrix. For example if the rref is ��has solution set (4-3z, 5+2z, z) where z can be any real number.

It takes Lucas 3 hours to cycle from his home to his friends village but if travels 5 mph slower, it will take him 1.5 hours lon

Alika [10]

The distance from friend's village to Lucas's house is 45 miles

Step-by-step explanation:

Lets assume the distance from Lucas home to friend's village is x miles

The time taken to cycle from Lucas home to friend's village is 3 hrs....t₁

The time taken if travelling at a 5 mph reduced speed is 1.5 hrs longer......t₂

t₂=4.5 hrs

t₁= 3 hrs

Speed for cycle in first instance, where t₁=3 hrs and distance is x miles

s₁=d/t = x/3 mph

Speed for cycle if travelling at a slower speed,

$s=\frac{x}{3}-5$

Time taken in the second instance when travelling at a slower speed

= $\frac{x}{\frac{x}{3}-5 }=4.5\\ \\\frac{3x}{x-15} =4.5\\\\\\3x=4.5(x-15)\\\\3x=4.5x-67.5\\\\\\67.5=4.5x-3x\\\\\\67.5=1.5x\\\\\\67.5/1.5=x\\\\\\45=x$

The distance from friend's village to Lucas's house is 45 miles

2.) -1

3.) 36

4.) 1/3

5.) 90

Step-by-step explanation:

1.) -12/a

-12/a -> -12/2

2.) a+ (-b)

a+(-b) -> 2+(-3)

=-1

3.) 3a (12-2b)

3a(12-2b) -> 3(2) (12-2x3)

6(12-6)

6(6)

=36

4.) 2a-c/b

2a-c/b -> 2(2)-5/3

4-5/3

=1/3

5.) 3abc

3abc-> 3x2x3x5

=90
