Answer:

(3x + 18) + 93 = 180

23 + X

Step-by-step explanation:

(3x + 18) + 93 = 180, its supplymentery

180 - 93 = 87

87 - 18 = 69

3x = 69

69/3 = 23

23 = X

Answer:

Step-by-step explanation:

Remark

You have to assume nothing you should have to assume. You have to assume that 93 degrees on 3x + 18 sit on the same straight line. If it just looks that way, you are on shaky ground. You must be told. It's a good thing to keep in mind. Likely you'll get more questions like this. Just be aware you should not have to assume anything to make the problem work.

If the two angles both have one leg on what is marked as a straight line, then the sum of the two angles must = 180

Solution

The first one is not true. 3x + 18 is smaller than 90 degrees because 93 is more than 90 degrees. If A is true then the line is bent a bit.

B is not true. We just found one equation that doesn't work.

C is not true either. The result of trying to solve C will make x minus because 93>90 and 18 when subtracted  makes 3x even more minus.

D is true

(3x + 18) + 93 = 180               Subtract 93 from both sides.

(3x + 18) + 93-93 = 180 - 93   Combine

(3x + 18) = 87                           Remove the brackets

3x + 18 = 87                             Subtract 18

3x+18-18 = 87-18                

3x = 69                                    Divide by 3

3x/3 = 69/3

Answerx = 23

E is not true because D is true.

The vegetable garden has 95 ripe plants. The number of tomatoes is 16 fewer than twice the number of squashes. How many of each
RideAnS [48]

Answer:

Tomatoes = 39.5

Squash = 55.5

Step-by-step explanation:

T (tomatoes) = S - 16

S + T = 95

we plug it in now

S + (S - 16) = 95

2s = 95 + 16

2s = 111

s = 55.5??

hm. Let's go with it

T = 55.5 - 16

T = 39.5

39.5 + 55.5 = 95

I...guess?

Factor completely 2r²-32​
diamong [38]

Answer:

2(r+4)(r-4)

Step-by-step explanation

First, you want to factor out 2 from both terms, which gives you 2(r^2-16). Then you want to recognize that (r^2-16) is factorable into 2 terms. If you multiply (r+4) by (r-4) then you are given (r^2-16) as a result.

Solve for x 8/14=x/37
Setler79 [48]

Hello there!

\frac{8}{14}=\frac{x}{37}

Explanation:

↓↓↓↓↓↓↓↓↓↓↓

First you had to switch sides of the equation.

\frac{x}{37}=\frac{8}{14}

Then you had to cancel by the common factor of 2.

\frac{x}{37}=\frac{4}{7}

You had to multiply by 37 from both sides of the equation.

\frac{37x}{37}=\frac{4*37}{7}

Simplify it should be the correct answer.

x=\frac{148}{7}

<em><u>Answer⇒⇒⇒x=148/7 </u></em>

Hope this helps!

Thank you for posting your question at here on Brainly.

Have a great day!

Plz help me im desparate....but actually dothe question and not just come up w/ a phony anwser.....
olga nikolaevna [1]
It might be helpful to write up the question like this:
300=100%
3=1%
120=

If you do this, you’ll see that the question is really easily solved by just finding the number necessary to multiply 3 with to get 120.

If you understand this, the rest should follow.
