Evaluate the expression for y= -1 -13y-16
Answer: y = -17/14
Step-by-step explanation:
y = -1 -13y - 16
First we must isolate the variable:
y+13y = -1 - 16
Next we must add like terms:
14y = -17
Finally, divide 14 on both sides:
14y/14= -17/14
Answer: y = -17/14

A Galapagos tortise can walk 1/5 mile in an hour. How many hours would it take for the tortise to walk 1/6 mile?
Answer:
0.834 hours
Given that,
A Galapagos tortoise can walk 1/5 mile in an hour.
We need to find time would it take the tortoise to walk 1/6 mile.
1/5 mile = 1 hour
1 mile = 1/1/5 = 5 hours
For 1/6 mile = 1/6 *5 = 0.834 hours
It will take 0.834 hours to walk 1/6 mile.

A first number plus twice a second number is 3. Twice the first number plus the second totals 21 . Find the numbers.
Answer:
x = 13
y = -5
Step-by-step explanation:
Let x = the first number
Let y = the second number
x + 2y = 3 2x + y = 21
You have two unknowns, so you need to equations to solve.
Solve the first equation for x:
x + 2y = 3
x = -2y + 3 Substitute this in for x in the second equation.
2x + y = 21
2(-2y + 3) + y = 21 Distribute the 2
-4y + 6 +y = 21 combine the y's
-3y = 15 Divide both sides by -3
y = -5
Plug -5 back in for either equation
x + 2y = 3
x + 2(-5) = 3
x -10 =3
x = 13

Each of the equal sides of an isosceles triangle is 5 times the third side. The perimeter of the triangle is 121 inches. Find the sides of the triangle.
Answer: The small side is 11, and the other two are 55, 55,
Step-by-step explanation:
So the perimeter adds up to 121 inches.
we know that two of the sides are 5x the 3rd side while being congruent.
11 times 5=55. 55 times 2=110. 110+11=121
Answer:
The third side is 11 inches
the 2 equal sides are 55 inches each side.
Step-by-step explanation:
X + 2(5x) = 121
x + 10x = 121
11x = 121
x = 121/11
x = 11

Answer:
a) aₙ = 6(n - 1), a₂₄ = 138b) aₙ = 2n + 1, a₂₄ = 49===============================
Sequence a)Ignoring the hexagon in the middle, we'll count the number of squares:
0, 6, 12, ...This is an AP with the first term of a₁ = 0 and common difference of d = 6.
Explicit formula for an AP is:
aₙ = a₁ + (n - 1)dSubstitute the first term a₁ and common difference d into equation:
aₙ = 0 + (n - 1)*6aₙ = 6(n - 1)The 24th term is:
a₂₄ = 6(24 - 1) = 6(23) = 138Sequence b)Count the number of circles:
3, 5, 7, ...This is an AP with the first term of a₁ = 3 and common difference of d = 2.
The explicit formula for this AP is:
aₙ = 3 + (n - 1)*2aₙ = 3 + 2n - 2aₙ = 2n + 1The 24th term is:
a₂₄ = 2*24 + 1 = 49As part of a communit service project at your house score you’re organizing a fundraiser at the neighborhood movie theater money raised will benefit of summer camp for children with special needs the missions charge is $10 per person 550 of which is used to pay the movie theaters rental fee the reminder is donated to the summer camp fund is the maximum capacity of the movie theater is 500 people what is the maximum amount that can be donated right in equation that shows how much money will be donated and then solve
The maximum amount to donate to the summer camp fund is $2,250.
2. The equation that shows the maximum amount to donate is y = 4.5x.
What is an equation?An equation is a mathematical statement that two values are equal.
Using an equation, two mathematical expressions are stated to have equivalent values.
Equations are expressed using the equation symbol (=).
Data and Calculations:The expected number of theater goers = 500 persons
Admission charge per person = $10
Movie Theater's rental fee = $5.50
Ticket fee = $4.50 ($10 - $5.50)
Let y be the maximum amount to donate to the summer camp fund
Let x be = 500
y = (10 - 5.50)x
y = 4.5x
The required equation for the maximum amount to donate is y = 4.5x
y = 4.5 x 500
y = 2,250
Thus, the maximum amount to donate to the summer camp fund is $2,250.
