The eqaution for this question would be:

(1/2w+3) - (1/4w+4)

For the first step we need to take away the brackers:

1/2w + 3 - 1/4w - 4

We can then group the unknown and the other values together :

1/2w - 1/4w +3 -4
= (1/2 - 1/4)w +3 -4

We can then proceed to calculate the answer:

(1×2/2×2 - 1/4)w -1
=(2/4-1/4)w -1
= 1/4w - 1

Therefore the answer is 1/4w - 1.

Hope it helps!

Given:
1 inch : 18 kilometers

Let us use the ratio and proportion method:

a:b = c:d where ad = bc

0.8 inches is 14.4 kilometers

1 : 18 = 0.8 : x
x = 0.8 * 18
x = 14.4 km

1.4 inches is 25.2 kilometers

1: 18 = 1.4 : x
x = 18 * 1.4
x = 25.2 km

2.1 inches is 37.8 kilometers

1 : 18 = 2.1 : x
x = 18 * 2.1
x = 37.8 km

Mitch used 1 4 pounds of beef to make 3 4 liters of beef strogonoff. If Mitch's recipe is for 1 liter of beef strogonoff, how ma

iren [92.7K]

option B) 3 pounds of beef is needed to make 6 times the recipe.

Step-by-step explanation:

step 1 :

Mitch used 14 pounds of beef = 34 liters of beef strogonoff

'x' pounds of beef = 1 liter of beef strogonoff

step 2 :

Rate = No. of pounds / No. of liters

(14 pounds / 34 liters) = (x pounds / 1 liter)

x = 14/34

x = 0.412

1 liter of beef strogonoff = 0.412 pounds of beef

step 3 :

To make 6 times the recipe = 6 $\times$ 0.412

= 2.5 pounds of beef ( approximately 3 pounds)
