Answer:

-68

Step-by-step explanation:

1/2(x+8)=-30

1/2x+4=-30

You then subtract 4 on both sides which makes:

1/2x=-34

Then you divided 1/2 on both sides:

x=-68

(Did I do this correctly, if not I appologize!)

ANSWER THIS QUESTION THANKS ✔✔
ladessa [460]

Answer:

Step-by-step explanation:

Any negative (when there is only one of them) will be the least. negatives are smaller than positives.

A fraction is less than a whole number. So far what you have is

___ ___ 3/15 , - 24/30

So now which is bigger? 11 or 11.5

Which would you rather have? 11 dollars or 11 dollars and 50 cents. 11.5>11

The correct order is 11.5    11    3/15   - 24/30

Find all angles and pls show steps ​
Ghella [55]

Answer:

Both angles have a measure of 134degrees, y = 27degrees.

Step-by-step explanation:

As per what is given in the problem:

There are 2 parallel lines, both are intersected by a transversal.

Remember the theorem, when two parallel lines are intersected by a transversal, then the alternate exterior angles are congruent.

The is meanse that:

3y + 53 = 7y - 55

Solve using inverse operations:

3y + 53 = 7y - 55

     +55         +55

3y + 108 = 7y

-3y            -3y

108 = 4y

/4      /4

27 = y

Now, substitute back in to find the value of the angle:

3y + 53

y = 27

3 ( 27 ) + 53

81 + 53

= 134

Since the angles are alternate exterior, they are congruent, hence both angles have a measure of 134degrees.
