15 - 4x = 6 - 3x<br><br>whats the answer. ​
Makovka662 [10]

Answer:9

Step-by-step explanation: First you add the 3x to both sides(the -4x and the -3x) and then you get 15-1x=6. Next you subtract 15 from 15 and 6, so you get -1x=-9. So then you divide both sides by -1 (do -1x over -1 equals -9 over -1). Last you do the dividing and you get x=9.

You are making a snack that includes 5/6 pound of almonds and 7/9 pound of cashews. Which is greater, the weigh of the almonds o
devlian [24]
To compare the answers, you need to have the same denominator. 

We know that, 18 is a common denominator between 6 and 9. 

(5/6)*3/3 => 15/18 (ALMONDS) 
(7/9)*2/2 => 14/18 (CASHEWS) 

As seen, the weight of almonds is 1/18 bigger than the cashews.

Hope I helped :)

Find the 76th term of the arithmetic sequence 17, 19, 21, ...
Dominik [7]

Answer: 167

Step-by-step explanation: To find the 76th term of this arithmetic sequence, we will be using our explicit formula which is shown below.

^{a}n = ^{a}1 (n - 1)d

Since we want to determine the 76th term, we are going

to substitute 76 in for <em>n</em> in our explicit formula.

Then, ^{a}1 will be our first term in our sequence which is 17.

Lastly, <em>d</em> is our common difference or the difference between each of the terms in our arithmetic sequence which is 2.

So we have ^{a} 76 = 17 + (76 - 1)(2).

Now we have all the information we need. Just simplify from here.

Make sure to apply order of operations because this is where many

students make mistakes. Inside the parentheses first!

(76 - 1) is going to be 75.

So we have ^{a} 76 = 17 + (75)(2).

Then, we have to make sure we multiply before we add.

So (75)(2) is going to give us 150.

So we have ^{a} 76 = 17 + 150.

Now just add to find that ^{a} 76 = 167.

So the 76th term is 167.
