To find the cross product, you can set this up as a proportion. Please see the attached paper for one of the proportions you could use.
You would then multiply the numbers that are diagonal from each other.
You would have 21(8) = 12x or
168=12x.
Your answer would be everything but (D) .
Answer:
y = 7x + 4? - 7 7
Step-by-step explanation:
That would be the inverse property of addition. When you add the
opposite of a number to that number, your sum will be zero. -a is the
opposite of a and -bi is the opposite of bi. When you add x + y (aka the
opposites) your total is absolutely nothing!
Answer:
2.56
Step-by-step explanation:
Monday: 2 * 2.21 = 4.42
Tuesday: 4.42 + 0.39 = 4.81
Wednesday: 4.81 - 1.76 = 3.05
Thursday: 3.05 - 1/5 * 3.05 = 3.05 - 0.61 = 2.44
Friday: 2.44 + 0.12 = 2.56
