Answer:

A: 5 behind the line

Step-by-step explanation:

You can make an equation: 8 - 6 - 4 - 9 + 6

Then you can solve it a little at a time:

8 - 6 = 2

2 - 4 = -2

-2 - 9 = -11

-11 + 6 = -5

Negative 5 is the same thing as 5 behind the line.

Hope this helps! :)

Answer:

A. Five behind the line.

Step-by-step explanation:

We can use a number line (see below) to solve this problem.

Start at 0.

Jump eight units to the right.

Then jump in succession six, four, and nine units to the left.

Finally, jump six units to the right.

You end up five units to the left of zero (five squares behind the line).

Mathematically,

0 + 8 - 6 – 4 - 9 + 6 = -5

Solve the equation using the distributive property and properties ofequally 1/2 (x+6)=18 what is the value of X

Natali [406]

x = 30

The distributive property says that we need to multiply what's in the brackets by 1/2 (so 1/2*x and 1/2*6) to get the equation 1/2x + 3 = 18.

Then we need to subtract our constant, 3, from boths sides to get 1/2x = 15.

Multiply both sides by two to isolate x and you get x = 30.

Hope this helps! :)

A rectangular field is 90 yards long and 60 yards wide.Give the length and width of another rectangular field that has the same

Ilya [14]

Answer:

The length and width of another rectangular field with same perimeter but a larger area is 80 m by 70 m

Step-by-step explanation:

The perimeter of the existing field is

2(l + b)

= 2(90 + 60) = 2(150) = 300 yards

So we want another field having the same perimeter but a larger area

The area we have here is 90 * 60 = 5,400 square yards

If we had 80 by 70

Perimeter will still be 2(70 + 80) = 150

But the area will be 80 * 70 = 5,600 square yards

I really need help on this please can someone help me thanks in advance

Answer: option 2 is the better option

Step-by-step explanation: well in this case as you are trying to find the individual prices of the candy bars, you would divide the total price by the amount of candy bars. So in this case for the first problem, you would take the total price: $6.75 and divide it by 10. The answer to this would be .675 but you would round it up to .68 so that you have a two digit decimal. Therefore the answer is .68 cents for each candy bar.

you would repeat this process for the second problem. Total price: $7.25 divided by 12 (candy bars). The answer in this problem would then be .60 cents per candy bar. Once we see how much each would be, it is just a matter of seeing which price is higher. In this case, the second option is the better option.

Sorry this was long, that's how i explain things, but i hope this helps

Find x A. 22√2 B. 22 C. 11√3/3 D. 11√3

mel-nik [20]

Answer

$22\sqrt{2}$

Step-by-step explanation:

First we gave a name to the side that is common for both triangles, can be Y for example.

Using trigonometric functions we can make a relationship between the two angles that we have and the magnitud of the side.

$sin(45)=\frac{11}{Y} \\$ , Because sin(x)= op/hip

$cos(60)=\frac{Y}{x}$ , Because con(x)=ad/hip

Having this equations, we can solve the system and find x

$Y=\frac{11}{sin(45)} \\Y=cos(60)*x$

we equal Y and solve

$\frac{11}{sin(45)}=cos(60)*x\\ x=\frac{11}{sin(45)*cos(60)} \\x=\frac{11}{\frac{\sqrt{2} }{2} *\frac{1}{2} } \\x=\frac{11}{\frac{\sqrt{2} }{4} } \\x=\frac{44}{\sqrt{2} }\\$

Then we rationalize

$x=22\sqrt{2}$

Hope you like it!
