9 + 10.4
= 19.4

2) C. 6
9 - (1/2)^4 * 48
9 - 0.0625 * 48
9 - 3
= 6

3) A. 2 times y divided by 7
4) C. 5p - 4
5) C. Step 2; 4(2) + 4(4x)

Hope this helps!

What is the value of fraction 1 over 3x3 + 5.2y when x = 3 and y = 2?

C. 19.4

just substitude the value into the equation given

Question 6(Multiple Choice Worth 1 points)
(06.01 MC)

What is the value of the expression 9 − (fraction 1 over 2)4 ⋅ 48?

D. 9

the answer is 8.9375,but the answer provided in whole number.You just need to round off to tge nearest whole number.

Question 7(Multiple Choice Worth 1 points)
(06.02 LC)

Which statement best describes the expression 2y ÷ 7?

A. 2 times y divided by 7

B,C and D are obviously wrong.It doesn't related on the equation given.A is the right answer

Question 8(Multiple Choice Worth 1 points)
(06.02 MC)

Which of these is the algebraic expression for "4 less than the product of 5 and some number?"

B. 4 − 5p

A,C and D are WRONG. it doesn't mention that 4 is the product of any unknown number.B is the right answer

Question 9(Multiple Choice Worth 1 points)
(06.06 MC)

The work of a student to find the dimensions of a rectangle of area 8 + 16x and width 4 is shown below:

A. Step 1: 8 + 16x
B. Step 2: 4(4) + 4(12x)
C. Step 3: 4(4 + 12x)
D. Step 4: Dimensions of the rectangle are 4 and 4 + 12x

In which step did the student first make an error and what is the correct step?

C. Step 2; 4(2) + 4(4x)

The first error is at the step 2.It doesn't show the right solution.4(4x),not 4(12x).That is obviously wrong.How could 16 can be 12 even the expression not multiply by any number yet ! that obviously WRONG. C is the right answer

<h3>Answer: Choice C</h3>

Explanation:

In this answer choice, we effectively have two columns. In the first column is simply R and B, with R over B. This represents spinning either red (R) or blue (B).

Depending on the outcome, you branch the same outcomes from that.

So if you spin R, then you'll have R and B branch off that. Same idea applies to blue as well.

Something like choice D doesn't work because we have R show up twice at the very bottom.

Help with these problems please, DUE T O D A Y !!!! I’ll try to make you guys brainlist who ever answers first

Answer:

19) n = -14

20) x = 4

21) b= -14

22) x = 2

23) x = -1

24) x = -9

Step-by-step explanation:

19) Use the distributive property to get rid of the parentheses. You will get: 20-4n = 76. So, n = -14.

20) Multiply both sides of the equation by 2 to get: -8 + x = -4. So, x = 4

21) Add 3 to both sides to get: $\frac{b}{14}$ = -1. So, b = -14

22) Use the distributive property to get rid of the parentheses. You will get: -40 - 5x = -50. Then, add 40 to both sides to get: -5x = -10. So, x = 2.

23) Use the distributive property to get rid of the parentheses. You will get: -72 = -64 + 8x. Then, add 64 to both sides to get: -8 = 8x. So, x = -1

24) Add 2 to both sides to get: $\frac{x}{3}$ = -3. So, x = -9

Hope this helps :)
