Чx-2(x+4)=22


How do I do this

Answers

Answer 1

Answer:

x = 7

Step-by-step explanation:

4x - 2(x + 4) = 22

Distribute:

4x - 2x - 8 = 22

Combine like terms:

2x - 8 = 22

Simplify and solve:

2x = 14

x = 7

Answer 2

Answer:

4x-2x-8=22

2x-8=22

2x=30

x=15

Answers

Answer:

x=2 and y=1

Step-by-step explanation:

Rewrite equations:

y=−x+3;y=x−1

Step: Solve

y=−x+3

Step: Substitute−x+3foryiny=x−1:

y=x−1

−x+3=x−1

−x+3+−x=x−1+−x(Add -x to both sides)

−2x+3=−1

−2x+3+−3=−1+−3(Add -3 to both sides)

−2x=−4−2x−2=−4−2

(Divide both sides by -2)

x=2

Step: Substitute2forxiny=−x+3:

y=−x+3

y=−2+3

y=1(Simplify both sides of the equation)

Hope this Helps you :)

If a triangle has A as 4 and B as 13, but C, the hypotenuse, is missing, what is C? I already got to square root of 185 but i don't understand what to do because you can't simplify it, please show your work/explain it

Answers

Answer:

C = √185 or 13.6 units.

and cannot be simplified any further because it is irrational.

Step-by-step explanation:

Since the triangle has sides A = 4 units and B = 13 units. With C as its hypotenuse side, from Pythagoras' theorem C² = A² + B².

So, substituting A and B into the equation, we have

C² = 4² + 13²

C² = 16 + 169

C² = 185

taking square root of both sides, we have

√C² = √185

C = √185

C cannot be simplified any further because it is irrational. It is best expressed as √185 which is a surd. C could also be expressed as a decimal. So using your calculator and taking √185, C = √185 = 13.605 ≅ 13.6 units.

The complete sentence is:

Walnuts stay fresh longer in the refrigerator or freezer.

Step-by-step explanation:

A complete sentence is a sentence that displays a complete idea. It comprises of a subject and a predicate that includes verb too.  

From the given two sentences, the complete sentence is the second sentence. 'Walnuts' is the subject and 'stay fresh longer in the refrigerator or freezer' is the predicate. A complete idea about the freshness of the walnuts have been stated in the sentence. On the other hand, the first sentence is a run-on sentence. In such a sentence, two sentences are merged together. This is done by adding the punctuation mark or coordinating conjunction to merge the sentences.

The hypotenuse of a 30 -60 -90 triangle is 13cm. What is the length of the shorter leg?

Answers

Answer:

(13/2) cm

Step-by-step explanation:

The hypotenuse here is of length 13 cm.  The shorter leg lies opposite to the 30° angle.  Recall that the sine function is defined as

              opposite side

sin Ф = -----------------------

                 hypotenuse

which, in this case, works out to:

                opposite side

sin 30° = -----------------------

                       13 cm

and so the length of the opposite side (which is also the "shorter leg") is

shorter leg length = (13 cm)(sin 30°) = (13 cm)(1/2) = (13/2) cm
