What does (5 x -4) - 8=

Answer:

I think your answer would be 13.5

Step-by-step explanation:

5 x 10 = 50

50 - 2 = 48

48 + 60= 108

108 / 8 = 13.5

Answer:

8/340.

Step-by-step explanation:

First thing to do is add up all of the ones. I know that it = 8, so we now have 8/. Now to figure out what the rest is... oh! I know! It's 5 x 68, which is 340, Meaning we know have 8/340.

Answer:

Answer:

A. 2 sinx cosx - 1 + 2 sin^2 x.

Step-by-step explanation:

sin2x = 2 sinx cosx

cos2x = cos^2x - sin^2x

So sin2x - cos2x =  2 sinx cosx - ( cos^2x - sin^2x)

But cos^2 x = 1 - sin^2 x, so we have:

2 sinx cosx - (1 - sin^2 x - sin^2x)

= 2 sinx cosx - 1 + 2 sin^2 x.

Answer:

5 feet

Step-by-step explanation:

When you place the 13 foot ladder, the ladder, floor, and wall forms a right triangle and the ladder will become the hypotenuse.

We use the Pythagorean Theorem. Let x be the distance from the building.

x^2 +12^2 = 13^2

x^2 + 144 = 169

x^2 = 169 - 144

x^2 = 25

Take the square root of 25 and you get 5

x = 5

Answer:

So, the factors of 45 are 1, 3, 5, 9, 15, and 45.

Step-by-step explanation:

Answer:

36 units

Step-by-step explanation:

The two legs of this right triangle are 9 and 12. In order to find the length of the hypotenuse, you must plug in the 9 and 12 to the Pythagorean theorem:

a^2 + b^2 = c^2, where a and b are legs and c is the hypotenuse

If you plug in the values 9 and 12, you get:

9^2 + 12^2 = c^2

= 81 + 144 = c^2

= 225 = c^2

= 15 = c

This means that the hypotenuse is 15 units long. Now, you just need to add all the sides to get:

9 + 12 + 15

= 36 units

(Also as a fun fact, a Pythagorean Triple is when the three sides of a right triangle are integers. It is good to memorize a few of these, like 3-4-5, 5-12-13, 7-24-25 and 8-15-17. The largest side value is always the hypotenuse, and if you multiply all the sides by a scale factor, you can get other triples. If you knew the 3-4-5 triple, you might have noticed that 9 and 12 are 3 times each of the legs 3 and 4. From that information, you could just multiply the 5 by 3 to get 15 for the hypotenuse of this triangle, which might've made this problem a little easier)

Answer:

Step-by-step explanation:

Answer: 5/8

Step-by-step explanation: The ratio is 10:16 because total of 16 pens and 10 being red.

The ratio of red pens to total pens as a fraction is 5/8.

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

The ratio of red pens to total pens can be expressed as a fraction. To find this fraction, we need to divide the number of red pens by the total number of pens.

The total number of pens in the box is 6 blue pens + 10 red pens = 16 pens

So, the fraction representing the ratio of red pens to total pens is:

10/16

It can be simplified by dividing both the numerator and denominator by 2, to get

5/8

So the ratio of red pens to total pens as a fraction is 5/8. This means that out of every 8 pens, 5 are red.

hE WILL HAVE TO DOWN LOAD 50 SONGS

Step-by-step explanation:

Answer:

3x + 2 = 14

3x + 2 - 2 = 14 - 2

3x = 12

3x/3 = 12/3

x = 4

Step-by-step explanation:

3x + 2 = 14

subtract 2 from both sides

3x + 2 - 2 = 14 - 2

combine like terms.

3x = 12

divide both sides by 3

3x/3 = 12/3

x = 4

Answer:

Which equation is true when the value of x is -12    HERE YOU GO!!

Step-by-step explanation:

tricky ... let's see ...

I notice that if we subtract xy from both sides we get

7x + xy - xy = xy - xy + 21

then

7x = 21

and

x = 21/7 = 3

so there is only one value of x that satisfies the equation

x = 3

Going back to the original equation we see that any value of y will satisfy the original equation

we can see this by rearranging things:

7x + xy - xy = 21

here, I have performed the subtraction of xy on the right side as above, but have left the left side undone

(so we don't lose the presence of y)

Note that the above can also be written as

7x + (x - x)y = 21

or

7x + 0y =21

now, since anything times zero equals zero,

y may be any number.

Let's summarize:

1) x = 3

2) y = anything

looking back at the original question;

1) the equation is true for all ordered pairs

FALSE (only one x works, not all x)

2) there are no x and y pairs for which the equation is true.

FALSE (x=3, y=anything) makes it true, i.e. (3,1)  

3) For each value of x, there is one and only one value of y that makes the equation true,

FALSE for each value of x, for the one value of x, x=3, y can be any number, which is an infinite number, not one

4) for each value of y, there is one and only on value of x that makes the equation true.

TRUE!! for all the infinite values of y you may pick, there is one and only one x you may pick, x = 3

Answer:

A: law

B:  The opposite of a number is its additive inverse. The sum of a number and its opposite is zero. (This is sometimes called the property of opposites ).

C: To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

Answer:

x-intercept: none

y-intercept: 4.5

linear

slope: 0

Step-by-step explanation:

Answer:

The equation is linear. Standard form:

7n - 6m - 4 =0

Step-by-step explanation:

Linear Equations

The linear equations are identified because all terms form a polynomial of degree 1 or zero (no variable).

The standard form of a linear equation is:

ax+by+cz+d=0

where x, y, z are the variables, and a,b,c are constants.

The equation:

7n - 8m = 4 - 2m

Is linear, both variables have an exponent of 1 and there is an independent term. Moving all terms to the left side:

7n - 8m - 4 + 2m =0

Simplifying:

7n - 6m - 4 =0

You question is a little unclear but I'm going to assume you meant how much the guinea pig walked.

The hamster walked 20 feet, and the guinea pig walked 1/4 less. So you find 1/4 of 20, which is 5. Then, you subtract 20 and 5: 20-5 = 15. So the guinea pig walked 15 feet.

Answer:

[tex]2\sqrt{2}[/tex] or [tex]\sqrt{8}\\[/tex]

Step-by-step explanation:

The formula is actually d= [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}[/tex]. Now first, we have to find points A and C.

Point A is (1,2) and Point C is (-1,0).

Now we have to substitute the values in. That would make it d =[tex]\sqrt{(-1-1)^{2} + (0-2)^{2}}[/tex].

To simplify the parentheses, it would get to d= [tex]\sqrt{(-2)^{2}+(-2)^{2} }[/tex].

To simplify the exponents, it would get to d = [tex]\sqrt{4+4}[/tex].

To simplify the square root, it would get to d = [tex]\sqrt{8}[/tex].

So the answer is either [tex]2\sqrt{2}[/tex] or [tex]\sqrt{8}\\[/tex].
