Answer:
Ruby is 11. Tanya is 14.
Step-by-step explanation:
Let Ruby's age eight years ago be x.
Tanya's age eight years ago = 2x.
Ruby's age now = x + 8
Tanya's age now = 2x + 8
Total age = [tex]x+8+2x+8=25[/tex]
[tex]3x+16=25[/tex]
Subtract 16 from both sides:
[tex]3x+16-16=25-16[/tex]
[tex]3x=9[/tex]
Divide both sides by 3:
[tex]\frac{3x}{3} =\frac{9}{3}[/tex]
[tex]x=3[/tex]
Ruby's age now [tex]=x+8=3+8=11[/tex]
Tanya's age now [tex]=2x+8=2(3)+8=6+8=14[/tex]
Answer:
Tanya is 14; Ruby is 11.
Step-by-step explanation:
Let T represent Tanya's current age and let R represent Ruby's current age.
We know that their ages add up to 25. So:
[tex]T+R=25[/tex]
8 years ago, Tanya was twice as old as Ruby. In other words, Tanya's current age minus 8 is the same as Ruby's current age minus 8 times 2. So:
[tex]T-8=2(R-8)[/tex]
We have a system of equations. We can solve by substitution. From the first equation, subtract R from both sides:
[tex]T=25-R[/tex]
Substitute this into the second equation:
[tex](25-R)-8=2(R-8)[/tex]
On the left, subtract. On the right, distribute:
[tex]17-R=2R-16[/tex]
Add 16 to both sides. The right side cancels:
[tex]33-R=2R[/tex]
Add R to both sides. The left cancels:
[tex]33=3R[/tex]
Divide both sides by 3:
[tex]R=11[/tex]
So, Ruby is currently 11 years old.
So, Tanya is currently 25-11 or 14 years old.
Check:
8 years ago, Ruby was 11-8 or 3 years old.
8 years ago, Tanya is 14-8 or 6 years old.
Tanya's age of 6 is 2 times Ruby's age of 3 so our answer is correct.

If the sun rises in the east, then it is morning, and if it is morning, the sun rises in the east.Victoria will play outside if and only if the weather is nice.What is a biconditional statement?A biconditional statement combines a conditional statement with its inverse. As a result, one conditional is true if and only if the other is also true. It frequently employs the phrase "if and only if" or the abbreviation "if." The double arrow indicates that the conditional must be true in both directions.
Examples are that if and only if the polygon is a quadrilateral, it has four sides. If and only if the polygon has four sides, it is a quadrilateral. If and only if the quadrilateral is a square, it has four congruent sides and angles.

than we subtract 30 from the 30 and 70
-10n=40

(3m^2 – 5m + 2)^2
Answer: 9m^4- 30m^3 +37m^2 - 20m + 4
Step-by-step explanation:
(3m^2 -5m +2)^2 is the same as (3m^2 -5m +2)(3m^2 -5m +2)
Now apply the distributive property 3 times to solve.
3m^2(3m^2 -5m + 2) = 9m^4 - 15m^2 + 6m^2
-5m(3m^2 -5m+2) = -15m^3 +25m^2 -10m
2(3m^2 -5m +2) = 6m^2 - 10m + 4
Now add the solutions
(9m^4 - 15^2 + 6m^2) (-15m^3 + 25m^2 -10m)(6m^2 -10m +4) =
9m^4- 30m^3 +37m^2 - 20m + 4
If c – a = b, which of the following statements is true?
A. a + b = c
B. c + b = a
C. a – c = b
D. b – c = a
If c – a = b, then true statement is A. a + b = c
What is commutative property?The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer.
Now the given statement is,
c – a = b
adding a to both the the side
c – a + a = b + a
⇒ c = b + a
Using commutative property of addition we get,
a + b = b + a
Therefore, we get
⇒ c = a + b
Thus the true statement is A. a + b = c

ILL MAKE MOST BRAINLIEST PLS ANSWER!!!
Answer:
I think the answer would be the fourth answer or the second answer.
sorry if its not the correct answer.
Step-by-step explanation:
D; 10.5x + 45 < 12.5x + 35
We are told that;
Charges of Company A; $10.50 for each t-shirt plus one-time design fee of $45. If x is the minimum number of shirts ordered so that the charge at Company A is less than the total charge at Company B. Thus;C_a = 10.5x + 45
Similarly, we are told that;
Charges of Company B; $12.50 for each t-shirt plus one-time design fee of $35. If x is the minimum number of shirts ordered so that the charge at Company A is less than the total charge at Company B. Thus;C_b = 12.5x + 35
Since we want to make C_a < c_b
Then, we will have;
10.5x + 45 < 12.5x + 35

2. One is a pen and the other is a pencil
3. Both are pencils
4. At least one is a pen
Four questions in total
Step-by-step explanation:
1. P(pen then pencil) = 15/25 × 10/25 = 3/5 × 2/5 = 6/25
2. P(pen then pencil) + P(pencil then pen) = 6/25 + 6/25 = 12/25
3. P(pencil then pencil) = 10/25 × 10/25 = 2/5 × 2/5 = 4/25
4. P(at least 1 pen) = 1 − P(no pen) = 1 − 4/25 = 21/25
An auto shop has 2 used vehicles for sale, 1 car and 1 truck. The truck is 3 years older than the car but 7 years older than one-half the car’s age. How many years old is the car?
Answer:
The car is 13 years old
Step-by-step explanation:
Lets say Car is x and the Truck is y, so the trucks age = x + 3 = y
Lets find the value of the Car or x
x + 3 = 1/2(x + 7)------- >
first we will divide x by 1/2 and 7 by 1/2, So...
x + 3 = (x / 1/2 + 7 / 1/2)------- >
x + 3 = 1/2x + 3.5------->
next Isolate variable x,
x + 1/2x = 3 + 3.5
1/2x = 6.5, So...
x = 13 and in turn, y = 13 + 3

The answer to this is: Map Key. Because, Large scale maps are typically used to show site plans, local areas, neighborhoods, towns etc. ... A 'small' scale map is one in which a given part of the Earth is represented by a small area on the map. Small scale maps generally show less detail than large scale maps, but cover large parts of the Earth. The answer to this is: North. Like the wind rose, the compass rose was coincidentally designed in a fashion that resembled the rose flower. It helped to orient a map in the proper reading direction and gave the relative directions for certain points on the chart. Before compass roses were used on maps, lines were drawn from central points. The answer to this is: Map. Because, a Map help you to find places where you need to go. The answer to this is: Map Key. Because, A map usually has a legend, or key, that gives the scale of the map and explains what the various symbols represent. Some maps show relief, or changes in[tex]UsedLess[/tex] elevation. A common way to show relief is contour lines, also called topographic lines. The answer to this is: Blue. Because Blue Water is mostly associated with the color blue. Uncolored versions of these symbols can be found in Earth, Air, Fire and Water Symbols.

The answer to this is: A system of vertical and horizontal lines. A grid system on a map is usually square and is represented by drawn lines on the map creating those squares. The purpose of the grid system is to give each point in the map an identifier, an address, by which we can refer to it by. The answer to this is: Map key Title, date, author, and sources usually appear on the map though not always together. The map's title tells what the map is about, revealing the map's purpose and content. For example, a map might be titled “Political Map of the World” or “Battle of Gettysburg, 1863.”Hope It Helped!~

How much salt is in a mixture containing 10 gallons of an 11% salt solution and 6 gallons of a 7% salt solution?
I think I can solve it but forming the equation is where I have problems.
Answer:
Step-by-step explanation:
There really isn't an equation because there isn't an unknown. If we create a table, the "equation" that you are talking about will be come apparent. Let's call the 2 solutions Sol 1 and Sol 2:
Gallons of solution * % salt = Gallons of salt
Sol 1
Sol 2
If we fill in this table according to the info we are given, we have 10 gallons of the 11% solution, and 6 gallons of the 7% solution, so
Gallons of solution * % salt = Gallons of salt
Sol 1 10 .11 = 1.1 gallons of salt
Sol 2 6 .07 = .42 gallons of salt
We multiply the Gallons of solution by the % salt to get the gallons of salt. There are 1.1 gallons of salt in solution 1 and .42 gallons of salt in solution 2, so in the mixture (which is 16 gallons) there is 1.1 + .42 gallons of salt, which is 1.52 gallons of salt.
