Answer:

The 2 triangles on the right and left are isosceles, so they have 2 equal sides. Consequently, the angles at the base are equal.

Because the opposite angles of a vertix are equal, the triangle in the lower part has the angles x, 58° and 47°.

Because the sum of the inner angles of a triangle is 180, x= 180- (58+47)

x= 180-105 = 75°

Answer: x = 72

Step-by-step explanation:

The triangle with ∠a is an isosceles triangle; the other two angles are congruent, let them be y

a + y + y = 180 (sum of angles in triangles)

58 + 2y = 180

Subtract 58 from both sides

2y = 122

Divide both sides by 2

y = 61°

In the triangle with ∠b, b is congruent to another angle, (isosceles triangle) let it be b.

b = 47°

y and b have a relationship with the other two of the angles with ∠x (vertical angles); let them be y and b.

y + b + x = 180

61 + 47 + x = 180

108 + x = 180

Subtract both sides by 108

x = 72

Answer:

A

Step-by-step explanation:

Simply guess and check, meaning the boys category must be divisible by 2 and the girls category must be divisible by 3

A: 24 boys ÷ 2 = 12 (equals a whole number so it is divisible; not a decimal)

36 girls ÷ 3 = 12 (both of the boys and girls are divisible by their corresponding numbers)

Yes

Now make sure the boys are a lower count than the girls as the ratio says it should be 2 to 3, meaning there are more girls than boys

B: 20 ÷ 2 = 10 (divisible)

35 ÷ 3 = 11.666 (this is a decimal answer so it is not divisible)

No

C: 36 ÷ 2 = 18

24 ÷ 3 = 8

Yes, they are divisible

Now lets check if boys have a lower count than girls

36 boys > 24 girls

This is not the solution as it doesn't reflect the correct ratio of less boys than girls

D: 35 ÷ 2 = 17.5 (not divisible)

20 ÷ 3 = 6.66 (not divisible)

The value of 'k' for the given system of equation that coincides  is 4

k=4

Given :

System of equations

[tex]2x+y=40 \\kx+2y=80[/tex]

The given equation is in the form of ax+by=c

When the two lines coincides then

[tex]\frac{a_1}{a_2} =\frac{b_1}{b_2} =\frac{c_1}{c_2}[/tex]

Lets make the coefficients proportional to each other and then solve for k

[tex]\frac{2}{k} =\frac{1}{2} =\frac{40}{80} \\\frac{2}{k} =\frac{1}{2} =\frac{1}{2} \\\\\frac{2}{k} =\frac{1}{2} \\4=k\\k=4[/tex]

The value of k from the given system of equation is 4

When the line coincides then the value of k is 4

Answer:

Ken class has a median of 84 while Judy class a median of 87

Step-by-step explanation:

Ken class has a median of 84 while Judy class a median of 87

Kens class has a mean score of 83, and Judy's class has a mean score of 86.43(rounded) so, judging by the mean, Judy's class is smarter. If we take a look at the median, (Ken: 84, and Judy: 87) then Judy's class is smarter. So, overall Judy's class is smarter than Ken's class.

Answer: a

Step-by-step explanation: because bess it says she has 6 and is 3 it says have of 6 is 3 so it is 3

The age of Tanisha is 6 years and the age of Bess is 12 years. Therefore, option D is the correct answer.

We need to find the age of Tanisha and Bess.

A statement that the values of two mathematical expressions are equal (indicated by the sign =).

Let the age of Tanisha be x.

Bess is 6 years older than Tanisha.

Now, Bess=x+6

Tanisha is half as old as Bess.

Now, Tanisha=1/2×Bess

⇒x=1/2×(x+6)

⇒x=6

So, Tanisha's age=6 years and Bess's age=12 years.

Answer:

x=5.9

Step-by-step explanation:

First, you want to isolate x so you have to subtract 31.7 from both sides. This will make the equation -3x=-17.7. Because they are both sides are negative, you can change both sides to positive so it will be 3x=17.7. Next, you want x to be 1 so you have to divide 3 in both sides. This will make the equation x=17.7/3. Simplify that to get x=5.9.
