Answer:

25/64

Step-by-step explanation:

To get this answer, first you need to use the distributive property:

(-3/8)(-5/8) - (1/4)(-5/8)

Next, multiply:

15/64 - (-5/32)

Change the negative signs into a positive sign:

15/64 + 5/32

Multiply 5/32 by 2 on both top and bottom:

15/64 + (5)(2)/(32)(2)

You will then get:

15/64 + 10/64

Now, add the numerators. You will get:

25/64

This is your answer. I hope it helped!

Answer:

The length of the longer side is 12 in

Step-by-step explanation:

Scaling

The dimensions of the photographic negative are 2 in by 1.5 in.

An enlarged print of it has a length of 9 in and it's equivalent to the shortest side.

Since the shortest side of the negative is 1.5 in, the scale factor is 9/1.5 = 6.

The longer side should have been enlarged by the same factor, thus the longer side is 2*6 = 12 in

The length of the longer side is 12 in

Step-by-step explanation:

Ermm can you explain what you mean by "opposite of"?

Do you mean additive inverse?

Answer:

yes they are equivalent because if you were to add those R's they would make 3r

Step-by-step explanation:

Answer:

[tex]18[/tex]

Step-by-step explanation:

[tex]x + y = 10 (1)\\ x - y = 6(2) \: \\ 2y = 4 \: \: ie \: y = 2 \\ x + y = 10 \\ x = 10 - 2 \\ x = 8 \\ x3 - y3 = (8 \times 3) - (2 \times 3) \\ = 24 - 6 \\ = 18[/tex]

Answer:

1

Step-by-step explanation:

So first we do (x^5)^2 which we know is just x^10 because of exponents of powers I believe it's called, basically you just multiply the two powers.

Then you do the bottom half which is x^3 * x^7 and that equals x^10 because of the product of exponent rule,

Then we do x^10/x^10 which = 1 because the same number over the same number is always 1.

Let me know if you have any questions

Answer:

Solving the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex] the answer is 1

Step-by-step explanation:

We need to solve the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex]

We know that exponent rule: [tex](a^m)^n=a^{m*n}[/tex]

Applying this rule in numerator

[tex]\frac{(x^5)^2}{(x^7)(x^3)}\\=\frac{(x^{5*2})}{(x^7)(x^3)}\\=\frac{(x^{10})}{(x^7)(x^3)}[/tex]

We know the exponent rule: [tex](a^m).(a^n)=a^{m+n}[/tex]

[tex]=\frac{(x^{10})}{x^{7+3}}\\=\frac{(x^{10})}{x^{10}}[/tex]

Now, using the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex]

[tex]=x^{10-10}\\=x^0[/tex]

We know that [tex]a^0=1[/tex]

So, [tex]x^0=1[/tex]

Solving the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex] the answer is 1

Answer: x=44.6

Step-by-step explanation: 30²= 900

                                             33²= 1089

                                             900²+1089²=1989²

                                             1089²=44.6

                                             x=44.6

Answer:

the answer is 35

Step-by-step explanation:

7(5)=35

Answer:

35

Step-by-step explanation:

When a variable is next to a number it means you are doing multiplication, like 7xm. So if m=5 it would be 7x5. And 7x5= 35

7m  (m=5)

=7xm

=7x5

=35

Answer:

Number of hot dogs sold =  56

Number of  hamburgers sold = 52

Step-by-step explanation:

Let

Number of hot dogs sold = x

Number of  hamburgers sold = y

We can make equation from given equations:

[tex]0.50x+1y=80[/tex] (Hot dogs were sold for $.50 (fifty cents), and hamburgers were sold for $1 (one dollar). The total money raised by your class was $80. )

[tex]x+y=108[/tex]  (Together you sold 108 hot dogs and hamburgers.)

Now we cam solve these system of equations to find value of x and y

[tex]0.50x+y=80--eq(1)\\x+y=108--eq(2)[/tex]

Subtract both equations to get value of x:

[tex]0.50x+y=80\\x\:\:\:\:\:\:\:\: + y=108\\-\:\:\:\:\:\:\:\: -\:\:\:\:\:\: -\\---------\\-0.5x=-28\\x=\frac{-28}{-0.5}\\x=56[/tex]

We get value of x = 56

Now putting value of x in equation 2 to find value of y

[tex]x+y=108\\56+y=108\\y=108-56\\y=52[/tex]

So, we get y = 52

Therefore,

Number of hot dogs sold = x = 56

Number of  hamburgers sold = y = 52

Answer:

30 units²

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

Here

b is the horizontal measure between 2 red points, that is 6

h is the vertical measure from the lower left point to the other horizontal line, that is 5, then

A = 6 × 5 = 30 units²

Answer:

$126

Step-by-step explanation:

$252/$18=$14 dollars per hour.

now take 14*9 and you get $126.

Answer:

$126

Step-by-step explanation:

Okay, so to solve this question, we need to get from 18 (hours) to 9. To do this, we obviously divide 18 by 2. Since we did this, we now have to do the same thing with the other side ($252.) 252 divided by 2 is 126. This means that if Chau made $252 in 18 hours,  he will make $126 in 9 hours.

Have a nice day! :)

Answer:

B. 11

Step-by-step explanation:

Valorie made five times more baskets, so if you replace the V in the equation with how many baskets she made (55), it would look like 55=5n. Divide 55 and the n by five to get rid the five in the equation. 11=n. Thus, the answer is B.
