Answer 1

Answer:

parenthesis, exponents, multiplication, division, addition, subtraction.

(14)/(7)(5)(-3)^2 solve exponent first and then the multiplication part (7x5)

(14)/(35)(9) 14 divided by 35 is .4

(.4)(9)=3.6 .4 multiplied by 9 is 3.6 <- that's the answer for 7

remember parenthesis first so we will do 6-1 first which is 5. after parenthesis, well do exponents. 5^2 is 25.

we will finish the big parenthesis which is the brackets, and 30-25=5. now it's 5 +5=10<- that is the answer for 9. Do I need to explain more/ if not i hope this helps you better understand this.

Chad buys peanuts in 2-pound bags. He repackages them into bags that hold 5/6 pound of peanuts. How many 2-pound bags of peanuts should Chad buy so that he can fill the 5/6-pound bags without having any peanuts left over

Answers

You need to get a whole so
5/6+5/6=10/6 not a whole
10/6+5/6 =15/6= not a whole
15/6 +5/6= 20/6 not a whole
20/6+5/6=25/6 not a whole
25/6+5/6=30/6
There are 5 wholes in 30/6 so 5 bags

How do I Express 18+24 as the product of the GCF and another sum

Answers

Answer:

$6(3+4)$

Step-by-step explanation:

We are asked to represent $18+24$ as the product of the GCF and another sum.

First of all, we will find the greatest common factor of 18 and 24.

Factors of 18: 1, 2, 3, 6, 9, 18.

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.

We can see that greatest common factor of 18 and 24 is 6. Let us write our given expression as product.

$6\cdot 3+6\cdot 4$

Factor our 6:

$6(3+4)$

Therefore, our required expression would be $6(3+4)$ .

12x-39greater than 9 and -4x+3<-6

Answers

Answer:

Step-by-step explanation:

When you have an inequality like this, you can treat it like an equation except for one part. If you ever divide or multiply it by a negative number or variable you have to flip the inequality. if it is equal to as well you keep that though. for instance

-5x ≤ 10

x ≥ -2

Anyway, in your case you have two inequalities, so you have to solve both and see what makes both true.

We'll start with 12x - 39 ≤ 9

12x - 39 ≤ 9 First add 39 to both sides

12x ≤ 48 Now divide both sides by 12, positive so no flipping

x ≤ 4

Next is:

-4x + 3 < -6 First subtract 3 from both sides

-4x < -9 Now divide both sides by -4, which means the sign flips

x > 9/4

Now, without even looking at the answers, what number or numbers are less than or equal to 4 and greater than 9/4? Well we pretty much described it there. All numbers starting from, though not including 9/4, which is 2.25, all the way up to, and including 4. B shows exactly that.

Final answer:

To solve the inequalities, the first is simplified to x > 4 and the second to x > 2.25 after applying proper arithmetic operations and considering the signs during division.

Explanation:

The student's question involves solving two inequalities, one of which is a linear inequality, and the other an inequality that requires adding or subtracting to isolate the variable. To solve the inequality 12x - 39 > 9, we add 39 to both sides to get 12x > 48, then divide both sides by 12 to find that x > 4. For the inequality -4x + 3 < -6, we subtract 3 from both sides to get -4x < -9, then divide by -4, remembering that dividing by a negative number reverses the inequality, resulting in x > 9/4 or x > 2.25.
