The first term in the sequence below is 2.

1 answer:

-7n + 9 because the common difference is -7, so you have -7n, and then by plugging in the term numbers and the values, you find out that you need to add 9 to the -7n, so the answer is -7n + 9

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.

What is the solution to the following system?<br> X+2y+z=9<br> X-y+3z=13<br> 2z=10

Vinvika [58]

Answer: x = 0; y = 2; z = 5

Step-by-step explanation:

x+2y+z=9

x-y+3z=13

2z=10

Start with the last equation: 2z = 10, therefore z = 5 [easy]

Let's rewrite the second equation with 1) z=5, and 2) rearrange to find x:

x-y+3z = 13

x - y +3*5 = 13

x = y-2

Now use the values for x [(y-2)] and y [5] in the first equation:

X+2y+z=9

(y-2) +2y + 5 = 9

3y +3 = 9

3y = 6

y = 2

Now that we have y [2] and z [5], let's use the first equation to solve for x:

x+2y+z=9

x + 4 + 5 = 9

x + 9 = 9

x = 0

====

Try the three values (x=0, y=2, and z=5) in any of the formulas. The result should/will equal the number shown.
