Johnny and Dustin both went bowling last weekend, but not together. Johnny went during open bowling time, paying $13 for shoe rental and $3 per hour. Dustin went on family night, when each hour was $4 and shoe rental was $3. As it turned out, they played for the same number of hours and spent the same amount. How much did each one spend? How many hours did each one bowl?

Answers

Answer:

10 hours

$43

Step-by-step explanation:

Given that:

Jonny:

Shoe rental = $13

Fee per hour = $3

Dustin :

Shoe rental = $3

Fee per hour = $4

Number of hours bowled is the same

Let number of hours bowled = x

$13 + 3x = $3 + 4x

3x - 4x = $3 - $13

-x = - 10

x = 10

Number of hours each bowled = 10

Amount spent :

Jonny:

$13 + 3x = $13 + $3(10) = $13 + $30 = $43

Dustin :

$3 + 4x = $3 + $4(10) = $3 + $40 = $43

Answers

Answer:

Option (4)

Step-by-step explanation:

From the picture attached,

ΔFGH ≅ ΔQRS

Therefore, ∠F ≅ ∠Q

m∠F = m∠Q

(2x + 10)° = (3x + 1)°

3x - 2x = 10 - 1

x = 9

m∠Q = (3x + 1)°

         = 27 + 1

         = 28°

Option (4) will be the correct option.

0=(2y−1)(8−y) Let y=u, y=d. What is the value of u×d

Answers

Answer:

The value of uxd=4

Step-by-step explanation:

since  y=u, y=d, y=y

y=1/2 and 8

2y-1=0

2y=1

y=1/2

8-y=0

8=y

1/2*8=4

Answer:

4

Step-by-step explanation:

0=(2y−1)(8−y)

Using the zero product property

2y-1 =0    8-y =0

2y =1     8=y

y =1/2  y= 8

Let y=u, y=d

u = 1/2    d = 8

We want the value of u*d

u*d = 1/2 *8 = 4

Why are inverse operations and
properties of equality important when solving
equations? Explain.

Answers

Answer:

An inverse operation is two operations that undo each other e.g. addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality. This gives us a couple of properties that hold true for all equations.

The Science Club went on a two-day field trip. The first day the members paid $70 for transportation plus $19 per ticket to the planetarium. The second day they paid $100 for transportation plus $16 per ticket to the geology museum. Write an expression to represent the total cost in dollars for two days for the n members of the club.

Answers

Answer:

$170 + $35n

Step-by-step explanation:

Given that:

First day:

Transport fare = $70

Fee per ticket = $19

2nd day:

Transport fare = $100

Fee per ticket = $16

Total cost in dollars for the two days for n members

Number of members = n

First day:

70 + 19n

Second day :

100 + 16n

Totak cost :

(70 + 19n) + (100 + 16n)

70 + 100 + 19n + 16n

170 + 35n

$170 + $35n

Identify an equation in point-slope form for the line parallel to y+-2/3x+8 that passes through (4, -5).

Answers

Step-by-step explanation:

Line parallel to the line y = -2/3 x + 8 also has the slope -2/3.

Since the line passes through (4, -5), we have (x - 4) written on the right side and (y + 5) on the left side.

Hence the equation is y + 5 = -2/3 * (x - 4). (B)

ABCD is a rhombus.
Find each angle.
Reason:

Plz answer ASAP, thank you

Answers

Answer:

Step-by-step explanation:

I sympathize. The question is not very clear: you don't know what A and B really are (I mean which vertex).

However it is a rhombus, and you are to assume that B follows A. So put A anywhere and make B follow it. They are supplementary which means they add to 180 degrees. All rhombi have that property.

A + B = 180

A/B = 2/1

Cross Multiply the second equation

A = 2*B

Put 2B into the first equation.

2B + B = 180         Combine the left terms

3B = 180                Divide both sides of the equation by 3

B = 180 / 3

B = 60

B = 60

A = 180 - 60 = 120

Label the two acute angles as 60 and the two obtuse angles as 120.

Acute: means less than 90

Obtuse: means more than 90

Answer:

A 33 degrees

Step-by-step explanation:

[tex]x \degree = 180 \degree - (23 \degree + 124 \degree) \\ \\ x \degree = 180 \degree - 147 \degree\\ \\ x \degree = 33 \degree \\ \\ x = 33[/tex]

Answer:

A) 33

Step-by-step explanation:

the angles of a triangle always add up to 180.

124 + 23 + x = 180

combine like terms

147 + x = 180

147 + x - 147 = 180 - 147

x = 180 - 147

x = 33
