Answer:
600 feet
Step-by-step explanation:
There are 60 seconds in a minute, so the trolley travels 60 times as far as it does in one second.
(60 seconds/minute) × (10 feet/second) = 600 feet/minute
The trolley goes 600 feet in a minute.

What is the answer and method for this equation?
Answer:
X = 15/16
Step-by-step explanation:
2(4-8x) + 6 = -1
8 - 16x + 6 = -1
14 - 16x = -1
-16x = -1 -14
-16x = -15
X = 15/16
Answer:
[tex]2(4 - 8x) + 6 = - 1 \\ 8 - 16x + 6 = - 1 \\ - 16x = - 1 - 6 - 8 \\ - 16x = -15 \\ 16x = 15 \\ \boxed{x = \frac{15}{16} }[/tex]

y is given already
[tex]\\ \rm\Rrightarrow 2x-6=2[/tex]
[tex]\\ \rm\Rrightarrow 2x=2+6[/tex]
[tex]\\ \rm\Rrightarrow 2x=8[/tex]
[tex]\\ \rm\Rrightarrow x=\dfrac{8}{2}[/tex]
[tex]\\ \rm\Rrightarrow x=4[/tex]
Answer:
x = 4; y = 6
Step-by-step explanation:
Set the x-values equal to each other and the y-values equal to each other.
The first value in parentheses is an x-value, and the second value in parentheses is a y-value.
x - 2 = 2x - 6
Subtract x from both sides
-2 = x - 6
Add 6 to both sides to get x by itself on the right.
-2 + 6 = x
4 = x
y - 3 = 3
Add 3 to both sides
y = 6
Check answers for the x-value:
4 - 2 = 2(4) - 6
2 = 8 - 6
2 = 2
Check answers for the y-value:
6 - 3 = 3
3 = 3

A number is multiplied by 8, and that product is added to 2. The sum is equal to the product of 2 and 21. Find the number
Answer:
The number is 5
BRAINLIEST, PLEASE!
Step-by-step explanation:
8x + 2 = 2(21)
8x + 2 = 42
8x = 40
x = 5
In the expression, the value of number is 5.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We can to given that;
The algebraic expression is,
''A number is multiplied by 8, and that product is added to 2. The sum is equal to the product of 2 and 21.''
Now,
Let a number = x
Hence, We can formulate;
⇒ x × 8 + 2 = 2 × 21
⇒ 8x + 2 = 42
Subtract 2 both side,
⇒ 8x + 2 - 2 = 42 - 2
⇒ 8x = 40
Divide by 8;
⇒ x = 5
Thus, The value of number = 5

Quadrilateral ABCD with parallel sides AB and
CD is shown below.
Quadrilateral RSTU is the image of quadrilateral ABCD after a transformation. Which statement is true?
B
If quadrilateral ABCD is reflected or rotated to form quadrilateral RSTU, then sides RS and TU
are not necessarily parallel.
If quadrilateral ABCD is reflected or rotated to form quadrilateral RSTU, then sides AB and RS
must be parallel or on the same line.
D
If quadrilateral ABCD is translated to form quadrilateral RSTU, then sides AB and RS are not
necessarily parallel or on the same line.
If quadrilateral ABCD is reflected, rotated, or translated to form quadrilateral RSTU, then sides
RS and T'U must be parallel.
Answer:
Option DStep-by-step explanation:
The rotation or reflection will change the direction of the image but the translation will leave the corresponding sides parallel.
Now the answer choices:
AIf quadrilateral ABCD is reflected or rotated to form quadrilateral RSTU, then sides RS and TU are not necessarily parallel.
Incorrect. Since RS and TU are parallel sides of same figure, they will remain parallel regardless the mentioned transformation. BIf quadrilateral ABCD is reflected or rotated to form quadrilateral RSTU, then sides AB and RS must be parallel or on the same line.
Incorrect. Since AB and RS are corresponding sides of the figures, the rotation will result in different angle between those sides. CIf quadrilateral ABCD is translated to form quadrilateral RSTU, then sides AB and RS are not necessarily parallel or on the same line.
Incorrect. Since it is just a translation, the corresponding sides will remain parallel. DIf quadrilateral ABCD is reflected, rotated, or translated to form quadrilateral RSTU, then sides RS and T'U must be parallel.
Correct. Since RS and TU are parallel sides of the same figure, they must remain as is regardless the reflection, rotation or translation.brainiest to whoever right

The cost of bowling is $5 per player for shoe rentals and $45 per hour to book a
lane. Suppose a group of f friends go bowling for h hours. Write an expression for
the total cost for the group of friends to go bowling.
Writing an expression consists of combining two or more variables, symbols, or numbers, with one or more mathematical operators to form a mathematical sentence that is based on a specific context
The expression for the total cost for bowling is 45·h + 5·f
The reason the above expression is correct is as follows:
The given parameters are;
The cost of shoe rentals for bowling per player = $5
The cost to book a lane per hour = $45
The number of people in the group of friends = f
The number of hours the friends go bowling = h
Required:
To write an expression for the total cost for the group of friends to go bowling
Solution:
Let the number of lanes the friends book= 1
The total cost, C, is the cost to book one lane at $45 per hour for h hours, plus the cost for the f number of friends to rent one shoe each at $5 per player (person)
Mathematically, C = 45·h + 5·f
The expression for the total cost for the group of friends to go bowling, is therefore;
45·h + 5·f

Referring to the figure, find the area of the
trapezoid shown.
The shape is 2 triangles. Find the area of each one and add them together.
1/2 x 6 x 10 = 30
1/2 x 10 x 12 = 60
30 + 60 = 90
Area = 90 square inches
Area of Trapezoid = ½ (a + b) h
= ½ (12 + 6) 10
= ½ × 18 × 10
= 1 × 9 × 10
= 9 × 10
= 90 in.²
▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄Express the formula d = rt in terms of the time, t. Use your formula to find the time when the distance is 40 and the rate is 8.
A)t= 4; 1 = 5
B)t= ; t = 0.2
C)t = dr; t = 320
D)t = d-r; t = 32
Answer:
t = d/r; t = 5
Step-by-step explanation:
Hi there!
1) Isolate t
d = rt
Divide both sides by r
d/r = rt/r
d/r = t
t = d/r
2) Solve for t when distance is 40 and the rate is 8
t = d/r
Replace d with 40 and rate with 8
t = 40/8
t = 5

12=-4(-6x-3) please help
Step-by-step explanation:
12=-4(-6x-3)
when minus is multiplied by minus then the result is plus,
12=24x+12
Now, subtract 12 from both sides,
12-12=24x+12-12
0=24x
Now, divide both sides by 24
0/24=24x/24
0=x
Answer and Step-by-step explanation:
First, distribute the negative 4 onto the negative 6x and negative 3.
12 = 24x + 12
Subtract 12 from both sides of the equation.
0 = 24x
Divide both sides of the equation by 24.
x = 0
To check our answer:
-4(-6(0) - 3) = 12
-4(0 - 3) = 12
-4(-3) = 12
12 = 12 ✓
So, x is equal to 0.
