Answer:

63

Step-by-step explanation:

[tex](w - 8) \degree + (2w - 1) \degree = 180 \degree \\ (linear \: pair \: \angle s) \\ (w - 8 + 2w - 1) \degree = 180 \degree \\ \\ (3w - 9) \degree = 180 \degree \\ \\ 3w - 9 = 180 \\ \\ 3w = 180 + 9 \\ \\ 3w = 189 \\ \\ w = \frac{189}{3} \\ \\ w = 63[/tex]

Answer:

2.75

Step-by-step explanation:

absolute value means it is always positive so in this case it stays the same

Answer:

2.75

Step-by-step explanation:

The absolute value of any number is it's positive variant. For example, the absolute value of -100 is 100. The absolute value of 100 is also 100.

Thus, the absolute value of 2.75 is simply 2.75

SORRY IF THIS IS WRONG..

Answer:

she has 3 quarters

Step-by-step explanation:

let's call the amount of dimes D

let's call the amount of quarters Q

you know that she has 11 coins in total,

so D + Q = 11.

you also know that each dime is worth 10 cents.

and each quarter is worth 25 cents.

so 10d + 25q = 155

this is a system of equations. solve by substitution:

d = 11 - q

10d + 25q = 155

10(11 - q) + 25q = 155

110 - 10q + 25q = 155

15q + 110 = 155

15q = 45

q = 45/15

q = 3

Answer:

It is positive (9)

Step-by-step explanation:

Negative ÷ negative = positive

Negative ÷ positive = negative

positive ÷ positive = positive

positive ÷ negative = negative

Negative × negative = positive

negative × positive = negative

positive × positive = positive

Positive × negative = negative

If both symbols are the same, it is positive. If one is positive and one is negative (different symbols), it is negative.

The result is 9. Since both the divisor (-3) and the dividend (-27) are negative, the final result is positive.

When dividing -27 by -3, the result is positive. In this case, the negative signs cancel out each other, and two negatives make a positive.

To understand why, think of division as the process of finding out how many times one number (divisor) can fit into another number (dividend). In this case, we are trying to find out how many times -3 can fit into -27.

-27 ÷ (-3) = 9

Here's the step-by-step calculation: -3 times 9 equals -27, which matches the dividend. So, the result is 9.

Since both the divisor (-3) and the dividend (-27) are negative, the final result is positive.

In conclusion, -27 divided by -3 is positive 9.

Answer:

81 pencils

Step-by-step explanation:

1. Set up variables

Pencils = p

notebooks= n

2. Set up a system of equations

p+n= 135                             (The amount of supplies bought)

1.75n +0.35p = 122.85       (Equation for the cost)

3. Solve the system of equations (I'll use substitution)

    a)p= 135-n  (I just rearranged it)

    1.75n + 0.35p= 122.85

     b) Substitute the first equation into the second)

    1.75n + 0.35(135-n) = 122.85

     c) Solve!

    1.75n + 47.25 - 0.35n = 122.85

    1.4n = 75.6

     n= 54

Serena bought 54 notebooks!

4. Substitute the number of notebooks into the first equation

p +n = 135

p + 54= 135

p = 81

Serena bought 81 pencils!!!

I hope this helps!!!!

Answer:

Serena purchased 81 pencils

Step-by-step explanation:

Let x = the number of pencils Serena bought

Let 135 - x = the number of notebooks Serena bought

1.75(135 - x) + .35x = 122.85       Multiply both sides of this equation by 100.

175(135 - x) + 35x = 12,285

23,625 - 175x  + 35x = 12,285

-140x = -11,340

x = 81 pencils

Answer:

Arc length = 54.85mm

Step-by-step explanation:

360/32 = 11.25

11.25 * 559 = 6288.75

6288.75 * 3.14 = 19746.675

19746.675/ 360 = 54.851875

Rounded to the nearest hundredth

Arc length = 54.85mm

The length of the arc is 54.9mm

Data given;

To solve this question, we have to use the formula of length of an arc which is given as

L = θ/360 * 2πr

To find the angle between each spoke, let's divide 360 by 32

[tex]\theta = 360/32\\\theta = 11.25^0[/tex]

Now that we have the value of the angle, let's substitute it and solve for the length of the arc.

[tex]L_a_r_c = \theta/360 * 2\pi r\\L_a_r_c = \frac{11.25}{360} * 2 * 3.14 * 279.5\\L_a_r_c = 54.9mm[/tex]

The length of the arc is approximately 54.9mm
