Linda is twice as old as Vera. Tanya is four less than four times the age of Linda. Their total age is two more than nine times the age of Vera. How old is Tanya, in years?
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
Let the age of Vera be x,
Linda's age = 2x
Tanya's age = (4 × 2x) - 4 = 8x - 4
Total Age = 9x + 2
so, let's Solve for x :
[tex]x + 2x + 8x - 4 = 9x + 2[/tex][tex]11x - 4 = 9x + 2[/tex][tex]11x - 9x = 2 + 4[/tex][tex]2x = 6[/tex][tex]x = 3[/tex]Age of Tanya :
[tex]8x - 4[/tex][tex](8 \times 3) - 4[/tex][tex]24 - 4[/tex][tex]20[/tex]Tanya's age is 20 years.
what is the value of x?
Answer:
x=18
Step-by-step explanation:
the sum of all the angles in a triangle is 180 degrees.
we can use this to get an equation:
5x-6 + 3x+13 + 2x-7 = 180
combine the x's to get:
10x-6-7+13=180
combine the numbers to get:
10x=180
divide both sides by 10 to get your answer:
x=18
A store sells 5-pound bags of potatoes for $2.35 or 8-pound bags of potatoes for $3.52. Based on this information, which statement is true?
I don't know what the answer choices are
5 pound = $2.35
8 pound = $3.52
2.35/5 = 0.47
3.52/8 = 0.44
The 8 pound bag costs less dollars per pound than the 5 pound bag

what is The expression 12+9g-30h factored using the GCF is and btw I already tryed 3
Hello!
Answer:
3(4+3g-10h)
Step-by-step explanation:
Hope this helps!
The GCF expression is 12+9g-30h is 3(4 + 3g - 10 h)
what is GCF?A group of numbers' greatest common factor (GCF) is the biggest factor that all the numbers have in common.
For example, 12, 20, and 24 have two common factors: 2 and 4.
The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
Given:
12+9g-30h
Now, to find the GCF we have to factorize the numbers
12= 2 x 2 x3
9 = 3 x 3
30= 2x 3 x 5
So, the Greatest common factor is 3.
Thus, the GCF expression is 12+9g-30h is 3(4 + 3g - 10 h)

Answer:
[tex]\frac{1}{10}[/tex]
Step-by-step explanation:
[tex]\frac{3}{5} +\frac{1}{6} =\frac{3*6}{5*6} +\frac{1*5}{6*5} =\frac{18}{30} +\frac{5}{30} =\frac{18+5}{30} =\frac{23}{30}[/tex]
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 6) = 30. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 6 = 30. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - three fifths plus one sixth = twenty-three thirtieths.
Subtract: [tex]\frac{2}{3} =\frac{23}{30} -\frac{2}{3} =\frac{23}{30}-\frac{2*10}{3*10} =\frac{23}{30}-\frac{20}{30}=\frac{23-20}{30} =\frac{3}{30} =\frac{3*1}{3*10} =\frac{1}{10}[/tex]
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(30, 3) = 30. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 30 × 3 = 90. In the next intermediate step, , cancel by a common factor of 3 gives [tex]\frac{1}{10}[/tex]
In words - twenty-three thirtieths minus two thirds = one tenth.
A group of friends wants to go to the amusement park. They have no more than $110 to spend on parking and admission. Parking is $17.75, and tickets cost $20.50 per person, including tax. Write and solve an inequality that can be used to determine xx, the number of people who can go to the amusement park.
Answer:
Inequality: 20.50x + $17.75 ≤ $110
Solve: 4 people can go to the amusement park
Explaination:
Inequality:
$110 = Amount of money they have
$17.75 = Parking Cost
$20.50 = Cost of tickets per person
Because they only have $110, they can't spend more than that amount.
Therefore, the inequality would be the ticket cost per person, times the amount of people being payed for (aka x) plus the parking cost is less than or equal to the amount of money they have to spend. Hence the inequality:
20.50x + $17.75 ≤ $110
Solve:
$110 - $17.75 = $92.25 (92.25 is how much is left for tickets after subtracting the parking cost)
$20.50 x 4 = $82 (4 tickets can be bought for the price of $20.50)
$92.25 - $82 = $10.25 (10.25 isn't enough for another person)
So, the solution to the inequality is 4 people can go to the amusement park.
What is a rational number between 1.4 and 1.6?
Answer:
Im sure of 1.5
Step-by-step explanation:
None
Answer:
1.6 is a rational number while 1.4 is not
16 and 10 are rational numbers so 1.6 will also be a rational number
√2 is 1.4 while the square of 1.4 is not 2
√2.56 is 1.6 and the square of 1.6 is 2.56

⚠️⚠️Please help⚠️⚠️ Pip and Ali share S785 in the ratio Pip:Ali = 4:1.
Work out Pip's share.
==========================================================
Work Shown:
x = Ali's share
4x = Pip's share, because it is four times bigger due to the ratio 4:1
x+4x = 5x = total amount of money = 785
5x = 785
x = 785/5
x = 157 dollars is Ali's share
4x = 4*157 = 628 dollars is Pip's share
Note that 157+628 = 785 to help confirm the answer.
A cloud drifted above an airplane that was flying at 5,300 meters per minute. In 22.5minutes, the cloud moved 7,920meters to the east at a constant velocity. What was the cloud's velocity?
Answer is 352 metres
Step-by-step explanation:-The cloud is moving at a constant velocity. This means that we can find the velocity of the cloud by dividing the distance it moved by time:-
[tex]v = \frac{d}{t} [/tex]
Where "v" is velocity, "d" is distance and "t" is time.
The cloud moved 7920 metres in 22.5 minutes, so :-
[tex]v = \frac{7920 \: m}{22.5 \: min} [/tex]
[tex]v = 352 \: m/min[/tex]
Therefore, the cloud's velocity was 352 m/min.

Equation of the line:-
[tex]\\ \sf\longmapsto y=2x-5[/tex]
Answer:
y = 2x - 5
Step-by-step explanation:
Assuming you require the equation of the line
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (3, 1 ) into the partial equation
1 = 6 + c ⇒ c = 1 - 6 = - 5
y = 2x - 5 ← equation of line

Find the measure of each angle indicated.
A D
A) 21°
C) 23°
E 25°
B) 80°
D) 20°
Let the missing Angle be " x "
We know that Measure of an exterior angle of a triangle is equal to sum of the opposite two interior angles,
that is :
x + 80° = 100°x = 100° - 80° x = 20°value of missing angle = 20°
