Answer:

x=4

Step-by-step explanation:

I used cross multiplication

7+2x/3=5

7+2x/3=5/1

7+2x(1)=5(3)

7+2x=15

2x=15-7

2x=8

x=4

Answer:

x = 4

Step-by-step explanation:

The goal is to get x by itself.

1. Multiply both sides by 3 and you are left with:

7 + 2x = 15

2. Subtract 7 from both sides and you are left with:

2x = 8

3. Simplify by dividing each side by 2 and you are left with the answer:

x = 4

Which expressions are completely factored? Select each correct answer. 32y10−24=8(4y10−3) 18y3−6y=3y(6y2−2) 16y5+12y3=4y3(4y2+3)

laila [671]

Answer:

Option A and Option C

Step-by-step explanation:

Option A: $32y^{10}-24 = 8(4y^{10}-3)$ This is completely factored as 8 is the Highest Common Monomial factor

Option B: $18y^{3}-6y = 3y(6y^{2}-2)$ This is not completely factored as 2 is still a common factor of 6y2 and -2.

Option C: $16y^{5}+12y^{3}=4y^{3}(4y^{2}+3)$ This is completely factored as 4y2 is the Highest Common Monomial factor

Option D: $20y^{7}+10y^{2} = 5y(4y^{6}+2y)$ This is not completely factored as 2y is still a common factor of 4y6 and 2y.

So the options that are completely factored are Option A and Option C

The partial blueprint of a house that includes 3 bedrooms is shown below. The scale is 2.75 inches : 3 feet. What is the actual length and width of Bedroom 3 in feet?

Bedroom 1 w=9.17; l= 11 in

Bedroom 2 w=7.33 in; l= 12.83

Bedroom 3 w= 11 in; l= 14.67 in

______________________________________

___________

2.75 inches : 3 or 2.75 in / 3 feet

________________

Can you see the updates?

______________

Bedroom 3 w= 11 in; l= 14.67 in

11 in * 3 feet / 2.75 in = 12 feet

14.67 in 3 feet / 2.75 in = 16 feet

_________________________

Answer

Bedroom 3 w= 12 ft ; l= 16 ft

Please help been stuck on this for 40 minutes

we have given y interms of x.

we have given that add 2 to x.

which means $y=x+2$

so we have $x=2 ,y=x+2=2+2=4$ .

so when x $=2 ,y=4$ .

$x=4,y=x+4=4+2=6.$ .

$y=x+2,y=6+2=8$ .
