Answer:
Breaking up the multiplicand 8 into (5+3) allows us to apply the associative property of multiplication. See below.
Step-by-step explanation:
5*7 = 35. We want the product 8*7. Note that 8 = 5+3. Thus, 8*7=(5+3)(7) = 35 + 21, or 56.
Answer: 54
Step-by-step explanation:
We know that 45 is 5/6. So that means 45/5=9. 9 is 1/6. 9x6=54 is 54. 54 is the number.
Answer:
69.4 degrees.
Step-by-step explanation:
Complementary angles add up to 90 degrees so we have the equation:
4x + 3 + x + 4 = 90
5x + 7 = 90
5x = 83
x = 16.6
The larger angle = 4x + 3
= 4(16.6) + 3
= 69.4 degrees (answer).
Answer:
14.6
Step-by-step explanation:
In the question, we are told that:
Yivgeny's gymnastics scores were 1.5, 1.7, 5.5, and 9.1.
In the question, we are also told that to calculate his total score, we add his top two scores.
Yivgeny's top two gymnastics scores are:
5.5 and 9.1.
Hence, his total scores = 5.5 + 9.1
= 14.6
Yivgeny's total scores = 14.7
