Evaluate . | 6a |- 10 for a = - 7

2 answers:

8 0

The answer would be 32. This is because once you input -7 you multiply -7 and 6 and end up with -42 but since it is in absolute value it turns into positive 42. Now it is 42 - 10. At this point all you do is subtract which will get you 32. Hope this helps ; )

Answer:

Step-by-step explanation:

| 6a | - 10, when a = -7, looks like | 6(-7) |- 10.

Must multiply 6(-7) first; the correct result is -42.

Then subtract 10, obtaining | -42 | - 10.

Evaluating | -42 |, we get 42 - 10

which is 32

Simplify the following: (r+s-t)-(r-s+t)

ArbitrLikvidat [17]

R+s-t-(r-s+t)

=2s-t is the answer

People think this answer would be just =2s but I have verified with an online calculator and the answer that textbooks look for regarding this is 2s-t

You would assume you would go r-r and thats 0 so no r's

you would say s-(-s) makes it plus and theres 2s

and you would say -t -(+t) is -t

that's why the answer is 2s-t

At first I also did t-(+t) and thought it would be no t's but the answer is in fact 2s-t

–6 + (–12)<br><br><br>Evaluate the expression

Elanso [62]

Answer:

-18.

Step-by-step explanation:

They're both negative numbers being added to each other, so you'd add 6 and 12 (which is 18) and then put a negative sign before the 18. Therefore, your answer is -18.

I hope this helps, have a nice day.

Solve for x in the equation x/2 = 17 user: solve for x in the equation x/2 = 17 user: apply the rules for order of operations to

Finger [1]

Well to solve for x you simply need to multiply both sides of the equation to isolate x, the answer will be x=34. the second question requires bedmas (brackets, exponents, division and multiplication, addition and subtraction)
It will be 224 no matter if you multiply or divide first

Answer:

D) right scalene

Step-by-step explanation:

Triangles are classified by their largest angle. The largest angle is a right angle, which is the little box.

Isosceles triangles have two sides that are the same. Whereas scalene triangles have three side lengths that are different.

Right scalene is the answer.

Anya makes a scale drawing of a bug. The scale of the drawing’s length to the actual bug’s length is 2 inches: 1/8 inch. The act

ioda

<h2>Hello!</h2>

The answer is: The Anya's drawing is 6 inches long.

Have a nice day!

To solve this problem, we need to consider the drawing's length with respect to the actual bug's size, so, the scale factor is:

$2in:\frac{1}{8}in\\\\2x(in):\frac{3}{4}in$

So, how long is Anya's drawing of the bug?

We can find it, using the following equation:

$(2x)in=\frac{2in*\frac{3}{4}in}{\frac{1}{8}in}=\frac{\frac{6}{4}in}{\frac{1}{8}in}=\frac{\frac{3}{2}in }{\frac{1}{8}in}\\\\(2x)in=\frac{\frac{3}{2}in }{\frac{1}{8}in }=\frac{3}{2}in*\frac{8}{1}in=12in^{2}\\\\(2x)in=12in^{2} \\\\x=\frac{12in^{2} }{2in}=6in$

Hence, the Anya's drawing is 6 inches long.

Have a nice day!
