5 0
8a - 4 = 25 + 6 (a - 8)

(distribute the 6)

8a - 4 = 25 + 6a - 48

(combine like terms 25 - 48)

8a - 4 = 6a - 23

( subtract 6a from both sides)

2a - 4 = -23

(add 4 to both sides)

2a = -19

(divide both sides by 2)

a = - 9.5

////CHECK/////

8 (-9.5) - 4 = 25 + 6 ( -9.5 -8)

(plug each side into a calculator)

-80 = -80

FINAL ANSWER:

a = -9.5

Which of the following statements is never true?
Serjik [45]
A.
Never true. The angles of an equilateral triangle are 60° each, so an equilateral triangle can never be a right triangle which has one angle 90°.

b.
Possible. An isosceles right triangle has angles 45°, 45°, 90°.

c.
Possible. The angles of an equilateral triangle are 60° each, so it's always an acute triangle.

d.
Possible. For example a triangle with angles 70°, 70°, 40° - the angles are less than 90°, so they are all acute, and there are two angles with the same measure, so it's an isosceles triangle.

The answer is A.

List three keywords that refer to addition.
Alchen [17]
In a word problem, it might not be clear which operation the problem is asking you to do. But, 3 key words from which you know the problem is asking you to add are: increase, together, and gained. Though these are not all of them, these are some of the (arguably) most important ones.
