Step 1: We know that Angle A B C Is-congruent-to Angle F G H because all right angles are congruent. Step 2: We know that Angle

B A C Is-congruent-to Angle G F H because corresponding angles of parallel lines are congruent. Step 3: We know that Line segment B C is-congruent-to line segment G H because it is given. Step 4: Triangle A B C Is-congruent-to Triangle F G H because of the

Triangles FGH and ABC are congruent because of the: AAS congruence theorem.

<h3>What is the AAS Congruence Theorem?</h3>

The AAS congruence theorem states that when two angles and one non-included side in one triangle are congruent to corresponding two angles and one non-included side in another triangle, then both triangles are congruent.

In the proof given, it is established that both triangles have two corresponding congruent angles, and also, BC ≅ GH which are non-included sides.

Therefore, both triangles are congruent because of the AAS congruence theorem.

A math test is worth 144 points and has 40 questions. True false questions are worth 2
forsale [732]

Step-by-step explanation:

x = number of true/false questions

y = number of multiple choice questions

x + y = 40

2x + 3y = 144

from the first equation we get

x = -y + 40

this identity we can then use in the second equation

2(-y + 40) + 3y = 144

-2y + 80 + 3y = 144

y + 80 = 144

y = 64

and

x + 64 = 40

x = -24

that does not make any sense.

something is wrong with the problem description.

just think about it :

40 questions - if all of them would be multiple choice tests (creating the max. possible points for 40 questions), we could have only 40×3 = 120 points.

but the description says 144 points.

for 144 points we need at least 48 (144/3) questions.

that does not fit.

the described system does not have any natural number solution. therefore we are getting such crazy numbers as result, when we try.

a student gets 86 problems on test correct and gets a grade of 98%. how many problems were on the test?
sashaice [31]
You could set up a proportion 

86/x = 98/100

Then solve for x, I'll do it by cross-multiplying. 

86 times 100 divided by 98 = 87.755102

87-88 problems

What is the value of 12x^-3 y-1 for x=-1 and y=5<br> A.-12/5<br> B.-180<br> C.-60<br> D.-5/12
Mkey [24]

Expressions are mathematical statements represented with the variables

The value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5

<h3>How to determine the value of the variable</h3>

The expression is given as:

12x^{-3} y^{-1}

When x = -1, the expression becomes

12 * -1^{-3} y^{-1}

Evaluate the exponent

- 12 y^{-1}

When y = 5, the expression becomes

- 12 * 5^{-1}

Evaluate the exponent

- 12/5

Hence, the value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5
