No answer is be 28%
5+9+7+4=25
7/25 + .28 =28%
Step-by-step explanation:
Let a be the amt of perfume A, and b be the amt of perfume B. We have been given that
<span>a+b=3</span> and that <span>a∗15+b∗35=63</span>
From equation 1, we substitute <span>b=3−a</span> so as to get, <span>a∗15+(3−a)∗35=63
</span> which means, <span>15a+105−35a=63</span> which means, <span>−20a=−42
</span><span> so a = 2.1 ounce and b = 0.9 ounce</span>
Answer:
answer is A
Step-by-step explanation:
the bigger the angle the longer the opposite side is
to find angle f, add 42+65=107
180-107= 73
so <F is the biggest angle so DF is the longest side

Answer:
1 - expressions that are equal in value even though they are written in different ways, 2 - a(b + c) = ab + ac, or a(b + c) = ab - ac, 3 - a number that divides evenly into another number; a number multiplied to get a product, 4 - a single term; multiple terms connected by an addition or subtraction sign, 5 - a mathematical statement that shows two expressions are equal using an equal sign, 6 - an expression that uses variables to state a rule, 7 - a relation in which for any given input value, there is only one output value.
