Answer:
x=30
Step-by-step explanation:
You have to isolate for x. This means you need to somehow get x on one side of the equation all alone. In this case it is x-9=21 which means some unknown number x with 9 subtracted from it is equal to 21. When we bring the -9 over to the other side to get the x all alone, we have to switch the sign of the -9 so it becomes +9. This means x=21+9, and if you add that you'll get 30!

Answer and Step-by-step explanation:
10 and 20 are the initial amounts, so they don't get a variable. The 3 dollars and 2 dollars every mile gets the variable since the occur every mile.
The equations are:
Blank 1: 3x + 10
Blank 2: 2x + 20
To find when they are equal, we equal the equations together.
3x + 10 = 2x + 20
x = 10
Plug 10 into either equation and solve.
Blank 3: 10 (At 10 miles, the equations are equal)
Blank 4: $40 (The will equal $40)

Carter has a piece of rope that is of a meter long. He
ties knots in the rope to divide it into 3 equal sections.
Use the expression
to find the length of each
section.
Each section of rope is meter long.
Answer:
1 foot
Step-by-step explanation:
1 meter = 3 feet
3 feet divided by 3 = 1 foot
The length of each section of the rope is 1 foot.
What is an expression?An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.Many authors make a distinction between an expression and a formula, with the former designating a mathematical object and the latter a claim about such objects.Solution -The piece of rope is 1m long.
Carter divided the ropes into three equal parts by tying up the knot.
1 meter = 3 foot.
Therefore, divide 3 by 3.
[tex]\frac{3}{3} =1[/tex] foot.
Therefore, each section is 1 foot long.

I NEED HELP WITH THIS one angle of a triangle measured 145 degrees. The other two angles are in a ratio of 2:3. what are the measures of those two angles?
Answer:
Step-by-step explanation:
A triangle has 180 degrees in total. One of the angles are 145 degrees, so we can subtract and get 35 degrees. Then, it says that the remaining angles are in a ratio 2:3. So, we would have:
[tex]2x:3x = 35 \\2x+3x = 35\\5x=35\\x=7[/tex]
Now that we know what x is, we can multiply that to our ratio:
[tex]2\cdot7=14 \text{ degrees for the first angle}\\3\cdot7=21 \text{ degrees for the second angle }[/tex]

Garrafa = C
Botella = B
C = 5B - - - - 1)
3 garrafas más 7 botellas = 11 litros
3C + 7B = 11
C = 5B

The cost of the hiking trip this year is 2/3of the cost of last year's trip. This year's trip cost $32
1. Write an equation that represents the cost of last years trip.
2.What was the cost of last year's trip
Answer:
The equation is ( 32/2 ) × 3 = 48.
Step-by-step explanation:
In order to find the answer, we must find one third of last years trip. To do this, we can simply divide the cost of this year's trip by two, 32/2=16.
Now if we multiply this years trip by 3, 16×3=48, we can see that the total cost of last years trip was $48.
If we'd like to turn this into a equation, it looks like this:
( 32/2 ) × 3 = 48.

Jarry is making a strawberry smoothie which measure is greatest the amount of milk cottage cheese or strawberry
Answer:
Milk
Step-by-step explanation:
The amount of milk, cottage cheese and strawberries used are given in the attached picture.
3/4 cup of milk
2/6 cup cottage cheese
8/12 cup strawberry
Converting the fractions to decimal :
3/4 cup of milk = 0.75
2/6 cup cottage cheese = 0.3333
8/12 cup strawberry = 0.66666
0.75 > 0.6666 > 0.3333
We can conclude that amount of milk is greatest, then strawberry and the least is cottage cheese.

(-3) to the sixth power in exponential form
Answer:
Step-by-step explanation:
A negative number raised to an even exponent gives a positive result so it is the same as 3 raised to 6. That is 3 x 3 x 3 x 3 x 3 x 3 = 729
The (-3) to the sixth power, (-3)⁶, is equal to 729.
To express (-3) to the sixth power in exponential form, we write it as (-3)⁶.
Now, let's calculate (-3)⁶ properly:
(-3)⁶ = (-3) * (-3) * (-3) * (-3) * (-3) * (-3)
Multiplying -3 by itself six times:
(-3) * (-3) * (-3) * (-3) * (-3) * (-3) = 729
Therefore, (-3) to the sixth power, (-3)⁶, is equal to 729.
By raising -3 to the power of 6, we obtain the result of 729.

Answer:
60 degrees
Step-by-step explanation:
As the triangle is similar angle don't change so 50+70=120 and the angle of a triangle total to 180 so 180-120=60
Answer:
60°
Step-by-step explanation:
As it is said that the triangles are similar so In the similar triangles corresponding angles are equal so
< A = 50°
<E = 70°
< B = < E = 70° { being corresponding angles of similar triangles }
Now
< A + <B + < C = 180° {Being sum of angles of triangle }
50° + 70° + < C = 180°
< C = 180° - 120°
< C = 60°
