Answer:
7x
Step-by-step explanation:
4x−6+3x+6
=4x+−6+3x+6
Combine Like Terms:
=4x+−6+3x+6
=(4x+3x)+(−6+6)
=7x

Therefore the answer will be;

The pounds of type B coffee she used is 64pounds
The pounds of type A coffee she used is 84 pounds
Answer:
x=-10
Step-by-step explanation:
since there's a given 120 degrees, and it's a isosceles triangle, we know that the line adds up to 180 (where the 120 degrees is). so 120+x=180, the interior angle measures 60 degrees. That being said, the 3 angles measure 60 degrees also. now there's a right angle mark on top, so we find the angle of the smaller triangle (near angle 2) by doing 90-60=30 degrees.
angle 2 is said to be x+160, and there's a line, which tells us that they must add to 180.. so x+160+30=180
x+190=180
x=-10.
