Answer:
If there are 2 quarters for every 3 nickels,
then there are quarters.
If there are 2 dimes for every quarter,
then there are dimes.
If the number of pennies and nickels together are equal to the number of dimes, then there are pennies.
This doesn’t make any sense
To complete the equation and tell which property you used.
(3×10)×8=___(10×8)
The property of basic operations that was used here is the:
1. Associative property of
multiplication where you can group or cluster certain values or numbers in an
equation and still yield the same product.
The missing value would be 3. Hence,
2. (3 × 10) × 8 = 3 (10 × 8)
Observe the parenthesis which has only moved from starting with three to
the value of ten.
Answer:
TU = 12
Step-by-step explanation:
Given
TU = x − 1
SU = 3x − 7
ST = x + 7
TU = ?
Then we can say that
SU = ST + TU
⇒ 3x − 7 = (x + 7) + (x − 1)
⇒ 3x − 7 = 2x + 6
⇒ x = 13
Finally, we get
TU = x − 1
⇒ TU = 13 - 1
⇒ TU = 12
Therefore,
ST = x + 7 = 13 + 7 = 20
SU = 3x − 7 = 3*(13) - 7 = 32
The temperature increased 17 degrees.
to add the difference of a negative and positive number, i added the absolute value of -4 (4) to the larger number (13) and got 17
