How do i write and a expression for 5 times the number 25 and then subtract the quotient of 14 and 7. i'm confused!?

Answers

"5 times the number 25" is just 25 multiplied 5 times. Then "the quotient of 14 and 7" is just 14 divided by seven. You need the parenthesis because of the PEMDAS rule. Am expression is nt the same as an equation. An equation has an equals sign, an expression does not. So the final expression would be:

(5 x 25) - (14 / 7)

2y – 3x = 9
4y + 3x = 12

A.
coincident

B.
not enough information

C.
inconsistent

D.
consistent and independent

Answers

Answer: D. consistent and independent

Step-by-step explanation:

The given system is $2y-3x=9\n4y+3x=12$

When we compare the coefficients of the corresponding variables of both the equations we get,

For y, $(2)/(4)=(1)/(2)$

For x, $(-3)/(3)=-1$

And $(1)/(2)\neq-1$ ,

⇒ The system in independent.

Therefore the system has one unique solution.

Since, if a system has a unique solution then the system is consistent .

Therefore, the system is consistent and independent.

The equtaion has only one solution because they cut each other only once and the are independent ..as both line are different. So it would be (d) consistent and independent

Samuel is looking at the floor plan of his house to determine how much carpet he needs to buy for his basement. Based on the floor plan of his basement, how can he decompose the measurements into expressions find the area? A) First, find two areas using (4m + 10m = 14m2) and (8m + 3m = 11m2). Next, add (14m2 + 11m2 = 25m2). B) First, find two areas using (4m x 10m = 40m2) and (8m x 3m = 24m2). Next, add (40m2 + 24m2 = 64m2). C) First, find two areas using (4m x 10m = 40m2) and (8m x 3m = 24m2). Next, subtract (40m2 - 24m2 = 16m2). D) First, add all the labeled sides using (4m + 10m + 12m + 3m = 29m2). Next, add the remaining sides (8m + 7m = 15m2).

Answer:

B) First, find two areas using (4m x 10m = 40m2) and (8m x 3m = 24m2). Next, add (40m2 + 24m2 = 64m2).

Step-by-step explanation:

Samuel should is looking to find the area of his basement in order to cover it with carpet.

An area is calculated by multiplying two dimensions (so answers A and D are not it).

Best solution is to divide the area into two large rectangles then ADD them together to get the total area.

The only scenario where he could have subtracted something based on his plan is if he would have multiplied the 10m by the 12m then subtracted the area that is not part of his basement (7mx8m). He would have achieved the same result of course, but by going a different way.

4. 3/4

Please help.. Show work for ALL problems please.

Answers

1. 78 = 0.15x
78 / 0.15 = x
520 = x.....so 78 is 15% of 520

2. | 3x - 2 | = 8 | x + 1 | = 1

3x - 2 = 8 -(3x - 2) = 8 x + 1 = 1 -(x + 1) = 1
3x = 8 + 2 -3x + 2 = 8 x = 1 - 1 -x - 1 = 1
3x = 10 -3x = 6 x = 0 -x = 2
x = 10/3 x = -2 x = -2

ur answer is : x = -2

3. 3y - 4x + 5 = 0
3y = 4x - 5
y = 4/3x - 5/3
slope = 4/3
