Answer:
x=-5
Step-by-step explanation:
opening the bracket on the LHS, we have
-8x-40= -3x+x-7-3
-8x-40= -2x-10
collecting like terms
-8x+2x= -10+40
-6x= 30
divide both sides by -6
x= -5
Answer:
I think the answer is B
Step-by-step explanation:
Sorry if it's wrong
% change= (new # - original #) ÷ original # x 100
original #= 98
new #= 62
% change= (62-98)/98 x 100
= -36/98 x 100
= -0.36734 x 100
= -36.73%
Rounded to nearest 10th of %= -36.7%
CHECK:
= 98 - (98 * 36.73%)
= 98 - (98 * 0.3673)
= 98 - 36
= 62 new #
