The Commutative Property of Addition

Step-by-step explanation:

They have a common denominator of 12

21/12+6/12+20/12+4/12+3/12+6/12=60/12=5 cups

or you could group ingredients with the same denominators

7/4+1/4+1/2+1/2+5/3+1/3=

8/4+2/2+6/3=

2+1+2=5

The Commutative Property of Addition says the order of the numbers doesn’t change the outcome.

lana [24]

Answer:

A = 20,000(1.05)^x

Step-by-step explanation:

To get the approximate value of the house after x years, we will use the compound interest formula

A  = P(1+r)^n

P is the principal = $20,000 (cost of house)

r is the rate = 5% = 0.05

x is the time

Substitute into the expressio

A = 20,000(1+0.05)^x

A = 20,000(1.05)^x

Hence the required expression is A = 20,000(1.05)^x

3s+2t−3 =c<br> −7s−5t =4<br> ​
irinina [24]

Answer:

c=

−4

3

s−t+

−4

3

Step-by-step explanation:

Let's solve for c.

3s+2t−3c−7s−5t=4

Step 1: Add 4s to both sides.

−3c−4s−3t+4s=4+4s

−3c−3t=4s+4

Step 2: Add 3t to both sides.

−3c−3t+3t=4s+4+3t

−3c=4s+3t+4

Step 3: Divide both sides by -3.

−3c

−3

=

4s+3t+4

−3

c=

−4
