Since both triangles are similar, therefore,
GM/XD = AG/KX
(x - 2)/6 = (x + 9)/9
Cross multiply
9(x - 2) = 6(x + 9)
9x - 18 = 6x + 54
Collect like terms
9x - 6x = 18 + 54
3x = 72
Divide both sides by 3
x = 72/3

Bruce flipped a penny 5 times. It landed on heads 2 times and tails 3 times. If he flips the coin a 6th time, which of the following statements is TRUE?
A.
It is equally likely to be heads or tails.
B.
It is not likely to be tails.
C.
It is more likely to be heads.
D.
It is more likely to be tails.
Answer:
The answer is A
Step-by-step explanation:
It doesn't matter which side the coin landed on in the previous flips. The coin only has 2 sides, heads and tails. Therefore, when it's flipped the 6th time, there is a 50% chance it will land on heads, and a 50% chance that it will land on tails. The answer is A.
solve this system using elimination. 3x - 4y = -5, -10x + 4 = 12
Answer:
x = -4/5, y = 13/20
Step-by-step explanation:
-10x + 4 = 12
-10x = 8
x = -4/5
3x - 4y = -5
3(-4/5) - 4y = -5
-12/5 - 4y = -5
-4y = -13/5
y = 13/20
Double check:
3x - 4y = -5
3(-4/5) - 4(13/20) = -5
-12/5 - 13 = -5 (true)

The probability of getting not blue marble is [tex]\frac{7}{8}[/tex].
What is probability?
Probability is a measure of happening or non-happening of the outcomes of a random experiment.
Probability formulaP(E) = number of favorable outcomes/ total number of outcomes
According to the given question.
Total number of red marbles = 5
Total number of yellow marbles = 4
Total number of green marbles = 5
Total number of blue marbles = 2
⇒ Total number of marbles = 5 + 4 + 5 + 2 = 16
So, total number of outcomes = 16
Now, probability of getting blue marble = [tex]\frac{2}{16} = \frac{1}{8}[/tex]
Therefore, the probability of getting not blue marble = [tex]1 -\frac{1}{8} =\frac{7}{8}[/tex]
Hence, the probability of getting not blue marble is [tex]\frac{7}{8}[/tex].

15 men can dig a trench og 90m in 3 hours. how long will it take 16 men to dig a trench of 48m long?
Answer:
1.5 hours
Step-by-step explanation:
Answer:
1.5 hours
Step-by-step explanation:
15 men can dig a trench 90 feet deep in 3 hours. So, first, we have to divide 90 by 3 to find the depth that 15 men can dig in 1 hour.
90/3 = 30
Next, we need to divide 30 by 15 to find how deep 1 man can dig in 1 hour.
30/15=2.
Now, since there are 16 men in this second project, we need to multiply 16 by 2 to find how much 16 men can dig in 1 hour.
16x2 = 32.
Finally, we have to add 16 to get 48.
Since we added the depth for 1 hour plus the depth for half an hour to get the total depth, we can say that 16 men can dig 48m in 1.5 hours.

Sonja uses 8 of the 12 eggs in her dozen eggs to make a breakfast casserole. Olga uses 5/6 of a dozen eggs to make scrambled eggs. Who uses make eggs? Explain your answe
Answer:
Olga will use 10 eggs, while Sonja will use 8, thus Olga will use more eggs.
Step-by-step explanation:
Given that Sonja uses 8 of the 12 eggs in her dozen eggs to make a breakfast casserole, while Olga uses 5/6 of a dozen eggs to make scrambled eggs, the following calculations must be performed to determine who uses more eggs:
Sonja = 8/12 = 0.666 x 12 = 8
Olga = 5/6 = 0.83333 x 12 = 10
Therefore, Olga will use 10 eggs, while Sonja will use 8, thus Olga will use more eggs.

I need help 6x-2y=10 x-2y=-5 solve by elimination
[tex] \begin{cases} 6x - 2y = 10 \\ x - 2y = - 5 \end{cases}[/tex]
Solve the system of equations by eliminating either x-term or y-term. We will eliminate the y-term as it is faster to solve the equation.To eliminate the y-term, we have to multiply the negative in either the first or second equation so we can get rid of the y-term. I will multiply negative in the second equation.
[tex] \begin{cases} 6x - 2y = 10 \\ - x + 2y = 5 \end{cases}[/tex]
There as we can get rid of the y-term by adding both equations.
[tex](6x - x) + ( - 2y + 2y) = 10 + 5 \\ 5x + 0 = 15 \\ 5x = 15 \\ x = \frac{15}{5} \longrightarrow \frac{ \cancel{15}}{ \cancel{5}} = \frac{3}{1} \\ x = 3[/tex]
Hence, the value of x is 3. But we are not finished yet because we need to find the value of y as well. Therefore, we substitute the value of x in any given equations. I will substitute the value of x in the second equation.
[tex]x - 2y = - 5 \\ 3 - 2y = - 5 \\ 3 + 5 = 2y \\ 8 = 2y \\ \frac{8}{2} = y \\ y = \frac{8}{2} \longrightarrow \frac{ \cancel{8}}{ \cancel{2}} = \frac{4}{1} \\ y = 4[/tex]
Hence, the value of y is 4. Therefore, we can say that when x = 3, y = 4.
Answer Check by substituting both x and y values in both equations.First Equation
[tex]6x - 2y = 10 \\ 6(3) - 2(4) = 10 \\ 18 - 8 = 10 \\ 10 = 10 \longrightarrow \sf{true} \: \green{ \checkmark}[/tex]
Second Equation
[tex]x - 2y = - 5 \\ 3 - 2(4) = - 5 \\ 3 - 8 = - 5 \\ - 5 = - 5 \longrightarrow \sf{true} \: \green{ \checkmark}[/tex]
Hence, both equations are true for x = 3 and y = 4. Therefore, the solution is (3,4)
