Answer: ∠A = ∠FEC

∠B = ∠EFC

∠BDA = ∠FCE

AB = EF

BD = FC

AD = EC

Step-by-step explanation:

We know that if two triangles are congruent then their corresponding parts are congruent.

This property is also known as CPCTC.

Given △ABD ≅ △EFC

Then ∠A = ∠FEC [corresponding angles of congruent triangles]

∠B = ∠EFC [corresponding angles of congruent triangles]

∠BDA = ∠FCE [corresponding angles of congruent triangles]

AB = EF [corresponding sides of congruent triangles]

BD = FC [corresponding sides of congruent triangles]

AD = EC [corresponding sides of congruent triangles]

Angle A ~ Angle FEC
Angle B ~ Angle EFC
Angle BDA ~ Angle FCE

AB ~ EF
BD ~ FC
AD ~ EC

An oil drilling company drills the same distance each day for 5 days. They started at an elevation of 121.175 feet and ended at

nirvana33 [79]

Answer:

$x=\dfrac{|-246.875-121.175|}{5}$

Step-by-step explanation:

Given that:

Same distance is drilled by the oil drilling company for 5 days.

Initial elevation = 121.175 feet

Final elevation = -246.875 feet

To find:

The equation to find the value of $x$ i.e. the distance drilled each day?

Solution:

To find the distance drilled each day, we need to divide the total distance drilled with the number of days taken to drill the total distance.

Total distance drilled can be found by subtracting the initial elevation from the final elevation and taking modulus because distance can not be negative.

Total distance drilled = | Final elevation - Initial elevation |

Total distance drilled = | -246.875 - 121.175 |

Therefore, we can write the expression as:

$x=\dfrac{|-246.875-121.175|}{5}$

$\Rightarrow x=\dfrac{|-368.05 |}{5} =73.61\ ft/day$

If twice a number is increased by 5 and this sum is multiplied by -3, the result is -57 . What is the number?

cupoosta [38]

Set it up like this, going from words on the page to letters and variables:
-3(2x+5) = -57. Twice a number is 2x, increased by 5 is 2x+5, and that is multiplied by -3 to get a total of -57. Distribute the -3 into the parenthesis to get -6x - 15 = -57. Move the 15 over by addition to get -6x = -42. Divide both sides by -6 to get that x = 7
