grandymaker [24]

Answer:

B. -4/3x - 7 = 1

Step-by-step explanation:

2/3x - 9 - 2x + 2 = 1
2/3x - 2x - 7 = 1
2/3x - 6/3x - 7 = 1
-4/3x - 7 = 1

Sever21 [200]

Answer:

Ethan rollerbladed each day $\frac{623}{d}$ kilometers.

Step-by-step explanation:

Given:

Ethan rollerbladed a total of 623 km over d days.

Now, to find the kilometers Ethan rollerblade each day.

Total number of distance rollerbladed = 623 km.

Total number of days = $d.$

As, Ethan rollerbladed each day the same distance.

Now, to get the distance Ethan rollerbladed in each day we divide total number of distance rollerbladed by total number of days:

$Ethan\ rollerbladed\ each\ day\ =\ \frac{Total\ number\ of\ distance\ rollerbladed}{Total\ number\ of\ days}$

$Ethan\ rollerbladed\ each\ day\ =\ \frac{623}{d}$

Therefore, Ethan rollerbladed each day $\frac{623}{d}$ kilometers.

Use substitution to solve the following system of linear equations and fill in the following blanks:

marissa [1.9K]

Answer:

$x=-4$

$y=3$

$z=-5$

Step-by-step explanation:

Given:

$x+y+z=-6$

$x-6y-7z=-29$

$-7y-5z=4$

Solve for $x$ in the 1st equation:

$x+y+z=-6$

$x+y=-z-6$

$x=-y-z-6$

Substitute the value of $x$ into the 2nd equation and solve for $z$ :

$x-6y-7z=-29$

$(-y-z-6)-6y-7=-29$

$-7y-z-13=-29$

$-7y-z=-16$

$-z=-16+7y$

$z=16-7y$

Substitute the value of $z$ into the 3rd equation and solve for $y$ :

$-7y-5z=4$

$-7y-5(16-7y)=4$

$-7y-80+35y=4$

$28y-80=4$

$28y=84$

$y=3$

Plug $y=3$ into the solved expression for $z$ and evaluate to solve for $z$ :

$z=16-7(3)$

$z=16-21$

$z=-5$

Plug $z=-5$ into the solved expression for $x$ and evaluate to solve for $x$ :

$x=-(3)-(-5)-6$

$x=-3+5-6$

$x=2-6$

$x=-4$

Therefore:

$x=-4$

$y=3$

$z=-5$

For part A the choices are 25 and 34 and for part b it is 2 and 10

diamong [38]

Answer:

Part A is 34

Part B is 2

Step-by-step explanation:

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.
