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

I really need help with this 6th grade work due today

DIA [1.3K]

Step-by-step explanation:

Length (L) = u

Breadth (b) = 6 mi

Perimeter (P) = 22 miles

Now we know

P = 2 (L+ b)

22 = 2 ( u + 6)

11 = u + 6

11 - 6 = u

u = 5

One-third of a storeâs inventory is childrenâs clothing. Two-fifths of its inventory is womenâs clothing. What fraction of the t

Eva8 [605]

Answer: C. 11/15

Step-by-step explanation:

Given : The fraction of stores inventory is children's clothing= $\dfrac{1}{3}$

The fraction of stores inventory is women's clothing= $\dfrac{2}{5}$

Since both events are independent.

Therefore, the fraction of the total inventory is children's or women's clothing = (Fraction of stores inventory is children's clothing ) + (Fraction of stores inventory is women's clothing )

$=\dfrac{1}{3}+\dfrac{2}{5}=\dfrac{5+2(3)}{15}$

$=\dfrac{11}{15}$

∴ The fraction of the total inventory is children's or women's clothing $=\dfrac{11}{15}$

Hence, the correct answer is C. 11/15 .

I need to know what the value is for x

hoa [83]

4/6 = x + 3/ 12 - x
4( 12 - x) = 6( x + 3)
48 - 4x = 6x + 18
-4x - 6x = 18 - 48
- 10x = -30
x = 3
