Equation: $83=5w+25 and 12 walks more

Step-by-step explanation:

Here is an equation: $83=5w+25

The $83 on the left represents the $83 goal for the bike (or the total amount of money that Taylor needs)

The 5w represents that Taylor earns $5 per time she walks the dog, with the w being the number of walks.

The +25 shows that Taylor has already earned $25 from walking the dog. (Not sure if you need it, but the $25 took 5 dog walks –– 5•5=25)

To solve:

83 = 5w + 25 –– Subtract 25 from both sides to get the variable term alone

58 = 5w –– Divide both sides by 5 to get w alone

11.6 = w –– Round this up to 12 because you can't really do 3/5 of a walk (this means Taylor needs to walk the dog 12 more times to earn enough to buy the bike)

Check:

83=5w+25 –– Replace w with 12

83=5(12)+25 –– Multiply

83=60+25 –– Add

83=85 –– This shows she will have $2 left over

Answer:

C. [tex]\frac{9}{14}[/tex] , 9:14 , or 9 to 14

Step-by-step explanation:

With there being 9 teachers and 5 aides, the total number of adults is 14, leaving a fraction of [tex]\frac{9}{14}[/tex] , 9 teachers and 14 adults. Checking to simplify, there are no shared values by 9 and 14, so it is in it's simplest form.

Answer:

A. x = -2

Step-by-step explanation:

Answer:

x = 2.2

Step-by-step explanation:

- 4 (2x + y = 3.4) + (8x + 2y = 11.6)

( - 8x - 4y = - 13.6) + (8x + 2y = 11.6)

- 2y = 2

y = - 1

2x + ( -1 ) = 3.4

2x = 4.4

x = 2.2

Answer:

  log(35)/log(7)

Step-by-step explanation:

The change of base formula is ...

  [tex]\log_b(a)=\dfrac{\log(a)}{\log(b)}[/tex]

You have b=7, a=35, so the rewrite is ...

  [tex]\log_7(35)=\boxed{\dfrac{\log(35)}{\log(7)}}[/tex]

Answer:

m+1

Step-by-step explanation:

1/3(9 - 6m) + 1/4 (12m-8)

Distribute

1/3 *9  - 1/3 *6m  + 1/4 * 12m - 1/4 *8

3 -2m + 3m -2

Combine like terms

-2m+3m +3-2

m+1

Answer:

what is your question.

Step-by-step explanation:

Answer:

a. x = 14 (see explanation)

b. the arrows along the lines

Step-by-step explanation:

The relationship of these two expressions is Same Side, which means their sum is 180.

plugging in

108 + 4x + 16 = 180 | Given

124 + 4x = 180 | Add the numbers

4x = 56 | Subtract 124 from both sides

x = 14 | Divide both sides by 4

Answer:

33 inches tall (see below)

Step-by-step explanation:

You can make a ratio to simplify the situation:

  75 in. tall                 x in. tall

----------------------  =  ---------------------

50 in. shadow       22 in. shadow

Cross multiply:

75 (22) = 50 (x)

1650 = 50x

33 = x

x = 33 in. tall

The polar form of the given complex number is:

[tex]W = \sqrt{12}* e^{-i*0.52}[/tex]

Here we have:

W = -3 + √3i

To get the polar form we first need the module of W it is:

|W| = √( (-3)^2 + (√3)^2) = √12

And now we need to find the bearing, that is given by the Arctangent of the quotient between the imaginary part and the real part.

Arctan(√3/-3) = -0.52 rad

Then the polar form is:

[tex]W = |W|*e^{-i*0.52} = \sqrt{12}* e^{-i*0.52}[/tex]

the answer is:

180-48= 132°

Answer:

i hope this helps you :))

Step-by-step explanation:

132

Linear pairs always equal 180 degrees.

Therefore, Angle ABC + Angle CBD =180.

We already know Angle CBD is 48.

Therefore, Angle ABC + 48 =180

Subtraction Property of Equality:

Angle ABC = 180-48= 132 Degrees.

Answer:

14(4n - 5)

Step-by-step explanation:

The GCF of 56 and 70 is 14

56/14 = 4

70/14 = 5

Place the GCF outside the parenthesis

14(

and keep the n on 56 and put it on 14, = 14n,

14(4n

then keep the subtraction sign and 5 and put it in the parenthesis

14(4n - 5)
