Answer:
Step-by-step explanation:
Since we have given that
Number of styrofoam balls bought by Bradley in May = 48
Number of toy figurines sold in May = 19
Number of styrofoam balls bought by Lupe in June = 44
Number of toy figurines sold in June = 21
So, we need to make a matrix that represents all of their May purchases and their June sales :
So, it is given by
May June
Purchases Sales
Bradley 48 19
Lupe 49 21
Thus, we can define a 2x2 matrix in which row 1 represents Bradley and row 2 represents Lupe. The columns then represent May and June. To distinguish between purchase and sale, we will show sale by a positive number and sale with negative; therefore the final matrix will be
Answer:
$2000
Step-by-step explanation:
The total debt divided by the number of people is ...
($8×10^11)/(4×10^8) = ($8/4)×10^(11-8)
= $2×10^3 = $2000 . . . per person
Answer: D
Reason: Both of the data shown is in no way symmetric
For the blank on the left, the answer is "angle ABC" without quotes of course. This is because we're using the substitution property which is the reasoning for statement 4. To elaborate, we connect statement 1 and statement 3 to get to statement 4.
The last statement, statement 5, is simply a repeat of the claim we want to prove. So you'll just copy/paste where it says "prove" as your last statement. Always start with the "given" and end up with "prove" is how I think of it.
The reasoning for the last statement is "definition of congruence". If two angles are congruent, then they have the same angle measure.
