Answer 1
Answer:

Answer:

−15x+−30

Step-by-step explanation:

Distribute:

=7+(−3)(5x)+(−3)(−10)+−67

=7+−15x+30+−67

Combine Like Terms:

=7+−15x+30+−67

=(−15x)+(7+30+−67)

=−15x+−30

Please help will give brainliest!CheapBuys, a large bulk store, sells cases of bottled water for $13.49. There are 48 bottles in each case and the bottles are 12 ounces each. Sarah remembers that the vending machine at work sells the same size bottle for $0.75 per bottle. Calculate the cost for one bottle and tell if Sarah should buy bottled water by the case or not. A: Buying in bulk will not save her any money since the bottles in the case and the bottles from the vending machine are both about 75 cents each. B: The cost per bottle at CheapBuys is approximately 28 cents, so Sarah will save a considerable amount of money by buying water in bulk rather than from the vending machine. C: Each bottle of water in the case from CheapBuys is 35 cents, so she should buy the case instead of buying it at work. D: The case of water is $13.49. Since the individual bottles are cheaper in the vending machine, Sarah should buy the bottles at work.

Provide the reasons for the fol owing proof Given: JK ≅ KL, NK ≅ KM
Prove ΔNKJ ≅ ΔMLK

1. JK≅KL,NK≅KM 1. Given

2.
3. ΔNKJ ≅ ΔMLK 3.________


ANSWER CHOICES

a. reflexive property of ≅ ; SAS
b. reflexive property of ≅ ; ASA
c. vertical angles are congruent; ASA
d. vertical angles are congruent; SAS

Answers

Answer:

Option d is correct.

Vertical angles are congruent;

SAS

Step-by-step explanation:

Given:JK \cong KL , NK \cong KM

In ΔNKJ and  ΔMLK

JK \cong KL and      [Side]                 {Given}

NK \cong KM      

Vertical angles states that the two lines intersect to make an X, angles on opposite sides of the X are called vertical angles.

i.e \angle NKJ and \angle MKL are vertical angles.

Also, vertical angles are congruent.

\angle NKJ \cong \angle MKL  [Angle]      [Vertical angles are congruent]

SAS(Side-Angle-Side) postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

then, by SAS postulates;

\triangle NKJ \cong \triangle MLK          Hence proved!

Therefore:

Statement                                                                      Reason

1.  JK \cong KL, NK \cong KM           Given

2.  \angle NKJ \cong \angle MKL                 Vertical angles are congruent

3. \triangle NKJ \cong \triangle MLK             SAS

Answer would be D, as the triangles are congruent due to being verticle angles (literally, you can just see theyre the same). Its SAS because you have 2 exact same sides, plus an exact same angle

A track runner was timed at 3 miles per hour. How many feet per minute did they run?3 miles/1hr = [x]feet/1minute

A) 264ft/minute

B) 60ft/minute

C) 15840ft/minute

D) 88ft/minute
I NEED HELP ASAP!!!!! PPPPPPPPPLLLLLLLLEEEEEEEEEAAAAAAAAASSSSSSSSSSEEEEEEEE!!!!!

Answers

Answer: A) 264ft/minute


Step-by-step explanation:

1. Based on the information given in the problem, the speed of the track  runner was 3 miles per hour (3(mi)/(h)).

2. If you want to know the speed of the track runner in feet per minute, you need to apply the following proccedure:

(3(mi)/(h))((5280ft)/(1mi))((1h)/(60min))=((3)(5280))/(60)=264(ft)/(min)

3. Therefore, the answer is the option A.
the correct answer is A

Answers

12=9m+4  First, switch sides so the equation makes sense.
9m+4=12  Then, subtract 4 from each side.
9m=8  Divide each side by 9.
m=0.888
