Jonny can build 3 1/2 lego planes in 60 minutes. How many can he build in 40 minutes

NeX [460]

Answer:

2.3lego

Step-by-step explanation:

We can walk through this problem using the cross multiplication method

First 3 1/2 lego is same as 3.5lego

Hence If

Johnny builds 3.5lego in 60min

He can build xlego in 40min

Crosss multiplying we have

Xlego *60= 3.5*40

Xlego= 140/60= 2.3lego

Which statement is true? A.27/19<11/30 B.17/31>19/14 C.16/26>30/31 D.35/30<22/12

Mrac [35]

A. $\frac{27}{19}$

To find greater than or smaller than relation, we multiply the terms like (numerator of L.H.S with denominator of R.H.S and put the value on the left side. Then multiply the denominator of L.H.S with numerator of R.H.S and put the value on right side. Now compare the digits.)

So, solving A, we get 810<209 ... This is false

B. $\frac{17}{31}>\frac{19}{14}$

= 238>589 ..... This is false

C. $\frac{16}{26}>\frac{30}{31}$

= 496>780 .... This is false

D. $\frac{35}{30}$

= 420<660 ..... This is true

Hence, option D is true.

The product of -2 and a number minus 6 is greater than -18

Eduardwww [97]

So product means multiplication so -2*(x-6) > -18 so divide by -2 on both sides to get x-6<9 because when you multiply a negative the sign swaps directions and then add 6 to get x<15
