Answer:
The expression equivalent to 8 - (6r + 2) is -6r + 6 ⇒ A
Step-by-step explanation:
Let us solve the question
∵ The expression is 8 - (6r + 2)
→ Multiply the bracket by (-)
∵ (-) × (+) = (-)
∴ 8 - (6r + 2) = 8 - 6r - 2
→ Add the like terms
∵ 8 - (6r + 2) = (8 - 2) - 6r
∴ 8 - (6r + 2) = 6 - 6r
→ Switch the terms
∴ 8 - (6r + 2) = -6r + 6
∴ The expression equivalent to 8 - (6r + 2) is -6r + 6
Answer:
20 ounces
Step-by-step explanation:
For this type of problem it is best to work backwards.
If David has 18, and Charlie gave him 1/2, then Charlie has 36 because 18x2=36. Barbara has 60, because 36/3= 12 and 5x12=60. Then, Amanda has 80 because 60/3=20 and 20x4= 80. But, we need to subtract 60 because the problem asks how many ounces of water does Amanda <em>still</em> have. So, 80- 60(The amount of water she gave to Barbara)=20.
Answer:
<h3>37.5m/s</h3>
Step-by-step explanation:
If a coal train in Montana starts from rest and accelerates at 2.5 m/s2 for 15s,let us calculate the final velocity of the train.
Use the equation of motion v = u + at where;
v is the final velocity
u is the initial velocity = 0m/s (starts from rest)
a is the acceleration = 2.5m/s²
t is the time = 15secs
Substituting the given parameters into the formula;
v = 0+(2.5)(15)
v = 0+37.5
v = 37.5m/s
Hence the final velocity of the train is 37.5m/s
