What is the answer to this problem
8x-2=-9+7×

Answers

8x−2=−9+7x

Simplify:

8x−2=−9+7x

8x+−2=−9+7x

8x−2=7x−9

Subtract 7x from both sides.

8x−2−7x=7x−9−7x

x−2=−9

Add 2 to both sides.

x−2+2=−9+2

x=−7

you want like terms on the same side. so you want x on the same side
subtract 7x from 8 x = x
add 2-9 = -7
now you have x= -7

A machine produces 75 widgets an hour. How many widgets does it produce in 6 minutes

Answers

75 divided by 60 times 6 equal 7.5

7widgets would be made in 6 minutes. Because there are 60 min in 1 hour, so 10 6 min spans in 1 hour, so 75/10=7.5 however you don't make half a widget and call it a full one so 7 every 6 min.

. Allison drew a triangle with 2 congruent sides and 1 obtuse angle. Which terms accurately describe the triangle? Select all that apply.

Answers

Answer:

obtuse triangle

isosceles triangle

Step-by-step explanation:

A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

Area of a triangle = 1/2 x base x height

the perimeter of a triangle = sum of the side lengths

An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side.

Answer:

obtuse triangle

isosceles triangle
