I think the correct answer from the choices listed above is the fourth option. The statement that is not true about David Hilbert would be that he wrote a biography on Euclid. Hope this answers the question. Have a nice day. Fee; free to ask more questions.
Answer:
angle L is congruent to angle W
Step-by-step explanation:
Corresponding parts of similar triangles are congruent/similar. It is for angles therefore the W and L are equal
5x+3y=7
2x-y=2
Since 2x does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 2x from both sides.5x+3y=7
-y=-2x+2
Multiply each term in the equation by -1.5x+3y=7_-y*-1=-2x*-1+2*-1
Multiply -y by -1 to get y.5x+3y=7
y=-2x*-1+2*-1
Simplify the right-hand side of the equation by multiplying out all the terms.5x+3y=7
y=2x-2
Replace all occurrences of y with the solution found by solving the last equation for y. In this case, the value substituted is 2x-2.5x+3(2x-2)=7
y=2x-2
Multiply 3 by each term inside the parentheses.5x+(6x-6)=7
y=2x-2
Since 5x and 6x are like terms, add 6x to 5x to get 11x.11x-6=7
y=2x-2
Since -6 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 6 to both sides.11x=6+7
y=2x-2
Add 7 to 6 to get 13.11x=13
y=2x-2
Divide each term in the equation by 11.(11x)/(11)=(13)/(11)
y=2x-2
Simplify the left-hand side of the equation by canceling the common terms.x=(13)/(11)
y=2x-2
Replace all occurrences of x with the solution found by solving the last equation for x. In this case, the value substituted is (13)/(11).x=(13)/(11)
y=2((13)/(11))-2
Multiply 2 by each term inside the parentheses.x=(13)/(11)
y=(26)/(11)-2
To add fractions, the denominators must be equal. The denominators can be made equal by finding the least common denominator (LCD). In this case, the LCD is 11. Next, multiply each fraction by a factor of 1 that will create the LCD in each of the fractions.x=(13)/(11)
y=-2*(11)/(11)+(26)/(11)
Complete the multiplication to produce a denominator of 11 in each expression.x=(13)/(11)
y=-(22)/(11)+(26)/(11)
Combine the numerators of all fractions that have common denominators.x=(13)/(11)
y=(-22+26)/(11)
Add 26 to -22 to get 4.x=(13)/(11)
y=(4)/(11)
This is the solution to the system of equations.x=(13)/(11)
y=(4)/(11)
The reason why Maria's experimental probability may be different from the theoretical probability of spinning a coin is because the theoretical is when you do not have the exact answer, which you kind of guess, while the experimental probability, you find out the exact answer of the problem.
Experimental probability: 62/100 of heads and 38/100 of tails
Theoretical probability: 50/100 of heads and 50/100 of tails (Since a coin only has two sides, which is heads and tails, the chance might be 50% of heads and 50% of tails.)
Hope this helped!

Answer:
AD = 4.5
Step-by-step explanation:
Since DE is parallel to AC and intersects 2 sides of the triangle it divides those sides in proportion, that is
=
, substitute values
=
( cross- multiply )
8AD = 36 ( divide both sides by 8 )
AD = 4.5
