Answer:

  1/4w -1

Step-by-step explanation:

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

  = 1/4w -1

_____

The distributive property applies. It is useful for distributing the minus sign and for collecting terms.

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!

A pizza stand offer both hand- tossed and pan pizza. customer can add any combination of the six available topping.
photoshop1234 [79]
The correct choice would be 128.

If there are 6 options and the person can pick any number of toppings, we need to know the number of subsets that can be formed with 6. That would be 2^6 or 64.

Since there is a pan or hand-tossed option, we need to multiply 64 by 2 to find the total.
64 x 2 = 128

How can these models be used to find the sum 1.8 + 1.56?
enyata [817]

Answer:

The sum of  1.8 and 1.56 is 3.36 according to the model

Sum of decimals

Given the expression  1.8 + 1.56

Using the partial sum method

1.8 + 1.56 = (1.0 + 0.8) + (1.0+0.56)

Regroup as whole and decimal number

1.8 + 1.56 = (1.0 + 1.0) + (0.8 +0.56)

1.8 + 1.56 = 2.0 + 1.36

1.8 + 1.56 = 3.36

Hence the sum of  1.8 and 1.56 is 3.36 according to the model
