Answer:
21a-14b
15b-20a
Step-by-step explanation:
Answer: a + 3b
Step-by-step explanation:
Okay, so...
7(3a - 2b) = 7(3a) - 7(2b) ... distributive property
21a - 14b
5(3b - 4a) = 5(3b) - 5(4a) ... distributive property
15b - 20a
(21a - 14b) + (15b - 20a) = 21a -12b + 15b - 20a =
a + 3b
Triangle ABC is a right triangle.
m∠A=5x°
m∠B=(3x−4)°
m∠C=90°
What is the value of x?
Answer:
11.75
Step-by-step explanation:
5x+3x-4+90 = 180
(the sum of interior angles of a triangle is always 180
8x-4+90 = 180
+4 +4
8x+90=184
-90 -90
8x=90
/8 /8
x = 11.75
The value of x from the given right triangle ABC is 11.75°.
What is angle sum property of a triangle?Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
Given that, triangle ABC is a right triangle with m∠A=5x°, m∠B=(3x−4)° and m∠C=90°.
Here, m∠A+m∠B+m∠C=180°
5x°+(3x−4)°+90°=180°
5x°+(3x−4)°=90°
8x°-4°=90°
8x°=94°
x=94/8
x=11.75°
So, 5x= 5×11.75 =58.75° and (3x−4)°=3×11.75-4
= 35.25-4
= 31.25°
Therefore, the value of x is 11.75°.

Answer:
radius: 3 units <----> Circumference: 18.84 units
Diameter: 12 units <----> Circumference: 37.68 units
Diameter: 36 units <----> Circumference: 113.04 units
Radios: 5 unites <----> Circumference: 31.4 units
Step-by-step explanation:
How I got the answers for the radiuses:
3 (this is only half the diameter so if you do 3 x 2 you will get the diameter.)
3 x 2 = 6
C = pi x d
C = 3.14 x 6
C = 18.84 [this is the first radios]
5 (this is only half the diameter so if you do 5 x 2 you will get the diameter.)
5 x 2 = 10
C = pi x d
C = 3.14 x 10
C = 31.4 [this is the second radios]
How I got the diameters:
12 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 12
C = 37.68 [this is the first Diameter]
36 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 36
C = 113.04 [this is the second Diameter]

Mixed numberMixed number is the combination of the whole number and the fraction number. The whole and the part of the whole combined can be expressed as a mixed numbers.
Now the given mixed number has to be divided. This number can be divided by converting into the proper fraction numbers. Let I is the result when the two numbers are divided. Thus,
[tex]x=8\dfrac{1}{2} \div 2\dfrac{2}{3} \\ [/tex]
To solve this convert the mixed numbers into the fraction number. For this multiply the denominator to the whole number and then add in the numerator. Thus,
[tex]x=\dfrac{16+1}{2} \div \dfrac{6+2}{3} \\ x=\dfrac{17}{2} \div \dfrac{8}{3} \\ [/tex]
Convert the divide sign into the multiply sign by changing the numerator to the denominator of one of the fraction.
[tex]x=\dfrac{17}{2}\times \dfrac{3}{8} \\ x=\dfrac{51}{16}\\[/tex]
As 16 can divide the number 51 in 3 times with reminder 3. Thus the mixed number for the above fraction can be written as,
[tex]x=3\dfrac{3}{16}[/tex]
Thus the result of the division of the two mixed number is [tex]3\dfrac{3}{16}[/tex].

2. Determine the value of x. Assume the segments that appear tangent
are tangent (input numerical answer only, if necessary round to one
decimal place)
Answer:
x = 16.8
Step-by-step explanation:
To get the value of x, we use Pythagoras’ theorem since what we have is a right angled triangle
Mathematically, we have it that;
the square of the hypotenuse (21) equals the sum of the squares of the two other sides
21^2 = 12.6^2 + x^2
x^2 = 21^2 - 12.6^2
x^2 = 282.24
x = √282.24)
x = 16.8

Arianna and Hansen are hosting events that are catered by the same company. Arianna plans to have 65 adults and 56 children attend, so the total projected cost of her meals is $3,003. Hansen has 86 adults and 62 children on his guest list, so he will pay the caterer $3,816. How much does the caterer charge for each meal? Choose the correct system of equation given that A stands for adults and C stands for children.
Answer:
C = $13
A = $35
Step-by-step explanation:
The computation is shown below:
Let us assume the Adults be A
And children be C
So the first equation would be
65A + 56C = $3,003
And, the second equation is
86A + 62C = $3,816
Now multiply by 86 in equation 1 and 65 in equation 2
5,590A + 4,816C = $258,258
5,590A + 4,030C = $248,040
786C = 10,218
C = $13
And A is
65A + 56($13) = $3,003
65A + $728 = $3,003
65A = $3003 - $728
65A = $2,275
A = $35

Here are five number cards 2, 5, 7, 8,9. One of the cards is removed and the mean average of the remaining four number cards is 6. Which card was removed you must show your working out
Answer:
7
Step-by-step explanation: Trust me
Answer:
Calculate the average of the five original cards:
2+5+7+8+9=31
31/5 = 6.2
So, if a card was removed, the four remaining cards would have an average of 6, meaning that they would add up to 24.
31-x=24?
Subtract 31 from both sides: -x=-7
Divide by -1 on both sides: x=7
So, we know that 7 was removed.

The Soup Shack usually makes tomato soup with 999 tomatoes for every 121212 bowls of soup. Today, they made 888 bowls of soup with 666 tomatoes.
Answer:
Same quanitity.
Step-by-step explanation:
The Soup Shack usually makes tomato soup with 9 tomatoes for every 12 bowls of soup.
Today, they made 8 bowls of soup with 6 tomatoes.
We need to compare today's soup to the usual recipe.
For 9 tomatoes for every 12 bowls of soup = [tex]\dfrac{9}{12}=\dfrac{3}{4}[/tex]
For 8 bowls of soup with 6 tomatoes = [tex]\dfrac{6}{8}=\dfrac{3}{4}[/tex]
It means we can see that both the soup has the same quantity. Hence, this is the required solution.
