These types of problems are all about recognizing key words. The word IS means EQUALS.
Eya is 3 times Bill's age but 5 less than that.
E = 3B - 5
If Eya is 28 now,
28 = 3B - 5
Add 5,
33 = 3B
Divide by 3 as a final step to solve for Bill's age.
Keep the "13" and focus on the "0.67."
Depending upon the degree of accuracy you want, you could convert "0.67" into 67/100, or 0.666666666666666... = 6/9 or 2/3. You'll then end up with 13 67/100 or 13 2/3.
Answer:
Step-by-step explanation:
For two matrix P and Q, the product, say PQ is defined when:
The number of columns of P = The number of rows of Q
Since A is a 2×2 matrix and B is also a 2×2 matrix
Thus both AB and BA are possible.
So AB is:
BA is:
Answer:
D. -8
Step-by-step explanation:
0-4=-4
0-4=-4
-4 + -4 = -8
