Answer:
84 degrees.
Step-by-step explanation:
First, let's define what a complementary angle is. It's when two angles add up to 90 degrees. So we do 90-6=84 and 84+6 does in fact equal 90, so they are complementary.
Answer:
19b-4
Step-by-step explanation:
7b+3(4b-2)+6÷3
Bracket comes first so we distribute 3 over the terms in the bracket
= 7b + 12b -6 +6 ÷ 3
First we solve division
= 7b + 12b -6 +6 ÷ 3
= 7b + 12b -6 +2
= (7b+12b)+(-6+2)
= 19b -4
This can't be simplified further as it can't be solved anymore
Answer:
The system of equations in standard form is equal to
The number of ounces of perfume A is 
The number of ounces of perfume B is 
Step-by-step explanation:
Let
a-----> the number of ounces of perfume A
b----> the number of ounces of perfume B
we know that
-----> equation A
-----> equation B
substitute equation B in equation A and solve for b
Find the value of a
-----> 
A+c = 150
10.25a+7.75c = 1470
