Answer:
just take speed =distance ÷time
dustance is speedxtime
14x1.61=22.54÷60 to change to min =0.37km per minute
0.40x0.37= 0.148 km
perhaps I may get wrong
If this is a question about who is correct Clair is correct
Answer:
18 - 6y
Step-by-step explanation:
6(3 - y) ← multiply each term in the parenthesis by 6
= 18 - 6y
Question: How do you solve [3.2 x (6.1 x 6.3)] - 2.8 with PEMDAS?
PEMDAS is the order of operations with which you solve an equation. So first parentheses, then exponents, then multiplication, then division, then addition, and last subtraction.
Answer: First, you solve the parentheses in the parentheses:
>6.1 x 6.3 = 38.43
Now ur equation is: (3.2 x 38.43) - 2.8
Now you solve what's inside this parentheses:
>3.2 x 38.43 = 122.976
Now you do the subtraction, because you have already solved all of what's in the parentheses:
>122.976 - 2.8 = 120. 176
And so, your answer is 120.176
This is what your equation should look like when you're solving:
>[3.2 x (6.1 x 6.3)] - 2.8 = y
>[3.2 x (38.43)] - 2.8 = y
>(3.2 x 38.43) - 2.8 = y
>122.976 - 2.8 = y
>122.976 - 2.8 = 120. 176
(3 + 2i) + (-4 + 6i)
Get rid of the parenthesis.
3 + 2i - 4 + 6i
Note how we got rid of the (+) sign in +(-4). We do this because a negative times a positive is always going to be a negative.
Combine like terms.
(2i + 6i) + (3 - 4)
Simplify.
8i - 1
