Answer:
B
Step-by-step explanation:
When a number is in front of the parethese, it is multiplying all the terms inside of it.
Looking at the first answer, the 2 multiplies 2/5x and 2, getting 4/5x + 4. This is not equivllent to 2 2/5x +1.
In the next one 2 is multiplying the same values, and results in 4/5x + 4. This is indeed equivelent to 4/5x + 4.
So this is your answer.
Hope this helps!

Answer:
140°
Step-by-step explanation:
Angles 1 and 3 are "corresponding" angles, so are congruent.
∠1 = ∠3
20x +60 = 30x +20
40 = 10x . . . . . . . . . . . . subtract 20x+20
4 = x . . . . . . . . . . . . . . divide by 10
∠1 = 20x +60 = 20(4) +60 = 80 +60
∠1 = 140°
Answer:
140°
Step-by-step explanation:
Angle 1 and angle 3 are corresponding angles ;
Corresponding angles are equal ;
Hence,
Angle 1 = Angle 3
20x + 60 = 30x + 20
Collect like terms
20x - 30x = 20 - 60
-10x = - 40
x = 4
Angle 1 is thus :
20x + 60 ; x = 4
20(4) + 60
80 + 60
= 140°

Step-by-step explanation:
-9-(-4)
solve the one in the bracket first because there is a minus sign between 9 and the bracket so we cannot use the 9 to multiple the number four in the bracket.
-9+4
the sign has changed to positive because when negative numbers are multiplying each other to will turn in to become positive.
so -9+4= -5
solution.
-9-(-4)
-9+4
-9+4= -5
therefore the answer is -5.

Answer:
38.13 = 12 +4.75h
5.5 hours
Step-by-step explanation:
(a) The charge (c) for renting a bike for h hours is ...
c = helmet charge + hourly charge × hours
c = 12.00 +4.75h
To find the number of hours when the charge is 38.13, we would use the equation ...
38.13 = 12.00 +4.75h
__
(b) To solve this 2-step linear equation, we first subtract the constant
26.13 = 4.75h
then we divide by the coefficient of the variable.
26.13/4.75 = h ≈ 5.5

Explanation:
f(x) is the outer function, so the final output -8 corresponds to f(x)
We see that f(-4) = -8 in the first column of the table. I'm starting with the output and working my way backward to get the input. So we started with -8 and worked back to -4.
Then we move to the g(x) function to follow the same pattern: start with the output and move to the input. We start at -4 in the g(x) bubble and move to 3 in the x bubble.
In short, g(3) = -4
So,
f(g(x)) = f(g(3)) = f(-4) = -8
We see that x = 3 leads to f(g(x)) = -8
What is the solution to the equation: 3 + 5 = 14 Show work.

This question did provide some clues to answer this question. Every week, the area covered by the algae is multiplied by 2^1.
To find the area cover increase by the algae per day, the exponent should be divided by 7 since there are 7 days in a week. Hence, every day, the area covered by the algae multiplies by 2^(1/7). In other words, 1 day after the algae was spotted, the area is 12.5 * 2^(1/7), which answers part B.
10 days after the algae was spotted, the area covered by the algae is 12.5 * 2^[(1/7)*10] = 33.6475... , which rounds up to 34 and answers part A.
