Which of the following equations has the same solution as m - (-62) = 45?

1 answer:

4 0

Hi Emmaelizabethmot286t

m - (-62) = 45 is the special equation so I'm a solve it and look for the same answer of the other options, so below is my work on how i got the answer of the special equation.

m + 62 = 45
m = 45 - 62
m = -17

The answer would be choice A) x + 25 = 8 and the x in that equation is -17 and -17 + 25 = 8 and that's true, and i figured out the answer by subtracting 25 from both sides and subtracting 8 - 25 so it can be -17.

Answer:

${8}^{x} \times {16}^{x } - 1 = 1 \\ {2}^{3x} \times {2}^{4x} = 1 + 1 \\ {2}^{7x} = {2}^{1} \\ 7x = 1 \\ x = \frac{1}{7}$

Masha biked 20km 20 minutes faster than Dasha biked 20km. Find the speed of each cyclist if one biked 2km/h faster than the othe

motikmotik

Answer:

12 km/h and 10 km/h

Step-by-step explanation:

Let the speed of Masha = s, speed of Dasha = d

Distance = 20 km
Time difference = 20 min = 1/3 hr
Speed difference = 2 km/h

As per above info we get following equations:

s = d + 2
20/s + 1/3 = 20/d

Substitute s and solve for d:

20/(d + 2) + 1/3 = 20/d

Get rid of fraction by multiplying all terms by 3d(d + 2):

60d + d(d + 2) = 60(d + 2)
60d + d² + 2d = 60d + 120
d² + 2d = 120
d² + 2d + 1 = 121
(d + 1)² = 11²
d + 1 = 11
d = 10

Find s:

s = 10 + 2 = 12

The answer is

Masha's speed 12 km/h and Dasha's speed 10 km/h

5 min=60 into 5
=300 sec
speed=distance/time
=62.5/300
=0.20833333333333.............
