Answer:

(2) is the correct answer

Step-by-step explanation:

if you multiply the given equation by 3 you get answer (2):

3(4x - 3y) = 3(12)

12x - 9y = 36

Answer:

(2) 12x-9y=36

Step-by-step explanation:

4x-3y=12  (×3)

12x-9y=36

Lin should have about 19 novels in total when you add up all the amounts she gets after 3 months.

Answer:

about 463 minutes or 7.7 hours

Step-by-step explanation:

area=length*width

4.75ft*3.25ft=15.4375ft^2

Now multiply 15.4375*30 to get 463.125 minutes

Answer:

8

Step-by-step explanation:

8*4 is 32 8*9 is 72

so, it is 8

since it is distributive property 8(4+9)

Answer:

8

Step-by-step explanation:

1) simplify the equation

32+72=104

104=4x+9x (distibute the "x")

104=13x

x=8

hence the "blank" is 8

Answer:

I'm in 10th grade so I'll see what I can do and will answer to the best of my ability.

Step-by-step explanation:

What Julie did wrong was, she did simplify she just did it wrong. She used 4*8 which does equal 32 but 8 can't be simplified anymore than that. If she would of used 2*16 then her answer would be right.

Hope this helps!

Answer:

[tex]5 \sqrt{18} - \sqrt{32} \\ = 5 \sqrt{9 \times 2} - \sqrt{4 \times 4 \times 2} \\ = 5 \times 3 \times \sqrt{2} - 2 \times 2 \times \sqrt{2} \\ = 15 \sqrt{2} - 4 \sqrt{2} \\ = \boxed{11 \sqrt{2} }[/tex]

Answer: -6<x<5

Step-by-step explanation:

Given

Length is 3 m more than three times the width

Suppose width is x

So, the length is 3x+3

The area of a rectangle is  [tex]length\times width[/tex]

Area= [tex](3x+3)x<90[/tex]

[tex]\Rightarrow 3x^2+3x-90<0\\\Rightarrow x^2+x-30<0\\\Rightarrow x^2+6x-5x-30<0\\\Rightarrow (x+6)(x-5)<0\\\Rightarrow -6<x<5[/tex]

Answer:

Daniel is rollerblading at 15 miles per hour

Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15

Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15

Step-by-step explanation:

Triangular Prism

Given a triangular prism of base area A and height H, its volume is obtained with the formula:

V = AH

The area of the base is calculated as follows:

[tex]A = \frac{WL}{2}[/tex]

Where W is the width and L is the length. Both dimensions must be perpendicular.

The triangle of the base has a hypotenuse equal to 10 in and the width is 6 in, the length is calculated by:

[tex]L=\sqrt{10^2-6^2}[/tex]

[tex]L=\sqrt{100-36}=\sqrt{64}[/tex]

L = 8 in

The area is:

[tex]A = \frac{6*8}{2}[/tex]

[tex]A = 24\ in^2[/tex]

Finally, the volume is:

[tex]V = 24\ in^2*14\ in[/tex]

[tex]\boxed{V=336\ in^3}[/tex]

Answer:

70

Step-by-step explanation:

70 students have a skateboard.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Total students are 125.

And to find the percentage of 56, we have to take the fraction.

56% of 125 students:

56 x 125 /100

= 7000/100

= 70

Therefore, 70 students have a skateboard.

Answer:

0

Step-by-step explanation:

the equation on finding slope is y2 - y1/x2 - x1

so it is...

6 - 6 = 0

6 - -5 = 11

0/11 but that doesnt work so I believe the slope is zero because the denominator is not the one being a 0

Answer:

Length=10 feet

Width=6 feet

Step-by-step explanation:

Let width (W) of the garden is x feet

Then Length=L=4+x feet

Perimeter=P=2(W + L)

P=2(x+x+4)

32=4x+8

4x=32-8

x=24/4=6 feet

W=6 feet

L=10 feet
