Since 12.3 is kind of a margin that you have to fit by, the total weight of the golf clubs must be lesser than or equal to 12.3. So, that's your expression:

x represents the number of golf clubs you have.

Answer:
The area would be 40.5 cm ^2
Step-by-step explanation:
Well first you don’t gotta worry about some isosceles trapezoid thingy.
You just gotta know the formula for a trapezoid is (b1+b2)/2)h
B1 in this case is or base 1 (9 or 4.5)
b2 in this case is or base 2 (9 or 4.5)
(you can only choose one base for each)
ANd you add those 2 up and you’d get 13.5
13.5/2 which is 6.75
Now we multiply it by the height which is 6 and gte 40.5
40.5cm ^2 is the final answer
64 + 5 = 69
69 + 64 = 133 cupcakes
Answer:
3.2seconds
Step-by-step explanation:
Step one:
Robert run the 100 meter dash in 13.5 seconds
We are told that he later run same distance in 10.3 seconds
Required.
The time difference in the first dash and the second
Step two:
The first dash took 13.5 seconds
the second took 10.3 seconds
the difference = 13.5-10.3= 3.2seconds
Answer:
Equation: 2x + 5 + 6x + 15 = 92
Solution: x = 9
m∠A =23° m∠B = 69°
Step-by-step explanation:
measure of ∠B = 3(2x + 5) = 6x + 15
The sum of the angles = 92 = 2x + 5 + 6x + 15
92 = 8x + 20
72 = 8x
x = 9
m∠A = 2(9) + 5 = 18 + 5 = 23
m∠B = 6(9) + 15 = 54 + 15 = 69
Check: 23 + 69 = 92 and 23(3) = 69
