-5.7+2.6d=-14.02 answer

1 answer:

8 0

d=-16/5 is the right answer. First, you had to multiply by 100 from both sides of the equation. And it gave us $-5.7*100+2.6d*100=-14.02*100$ . Then, you had to refine. And it gave us $-570+260d=-1402$ . Third, you can also add by 570 from both sides of the equation, and it gave us $-570+260d+570=-1402+570$ . Then simplify and it gave us, $260d=-832$ . Next, you had to divide by 260 from both sides of equation. And it gave us, $\frac{260d}{260}= \frac{-832}{160}$ . And finally, simplify it's should be the right answer. And it gave us the answer is d=-16/5 is the right answer. Hope this helps! Thank you for posting your question at here on brainly. And have a great day! -Charlie

If an elevation 20 meters below sea level is represented by the number -20, which of the following can best be represented by th

andreyandreev [35.5K]

Your answer would be B. An elevation at sea level
This is because if you picture it like a grid, -20 on the y axis is below 0, and 0 on the y axis is the y axis, so it would be on sea level.

−3(3+x)+4(x−6)=−4. please I need this now

nalin [4]

Answer:

x=29

Step-by-step explanation:

−3(3+x)+4(x−6)=−4

(−3)(3)+(−3)(x)+(4)(x)+(4)(−6)=−4(Distribute)

−9+−3x+4x+−24=−4

(−3x+4x)+(−9+−24)=−4(Combine Like Terms)

x+−33=−4

x−33=−4

Step 2: Add 33 to both sides.

x−33+33=−4+33

x=29

Una tirolina de 26 m de largo está atada entre dos postes que están separados por 24 m. Si Manuela monta la tirolina desde el pr

Answer:

The difference between the heights of the poles is 10m

Step-by-step explanation:

The distance between poles is 24 m

The length of the cable is 26m

You first use the Pythagoras' theorem to calculate the vertical distance between the end of one pole and the end of the other one.

$c_2=\sqrt{h^2-c_1^2}\\\\c_2=\sqrt{(26m)^2-(24m)^2}=\sqrt{100}m=10m$

The difference between the heights of the poles is 10m

The higher pole has height of 50m

Then, the lower pole has a height of 50m - 10m = 40m
