Here's a riddle
A horse travels a certain distance each day. Strangely enough, two of its legs travel 30 miles each day and the other two legs travel nearly 31 miles. It would seem that two of the horse's legs must be one mile ahead of the other two legs, but of course, this can't be true, since the horse is normal. How is this possible?
You can search the answer

Answers

Answer: the horse does more work on one of the pairs so they went a different distance.

Answer:

The horse operates a mill and travels in a circular clockwise direction. The two outside legs will travel a greater distance than the two inside legs.

Answer:

z = -6

Step-by-step explanation:

5z + 2 = 3z - 10

Subtract 3z from both sides

2z + 2 = -10

Subtract 2 from both sides

2z = -12

Divide each side by 2

z = -6

So, the answer is z = -6

When given a system of equations in​ slope-intercept form, is graphing or substitution the most efficient method to​ solve? Explain.
Choose the best answer below.
A.
Substitution is the only method that should be used if the answer involves integer values. If the answer involves values that are not​ integers, graphing would be more efficient because an exact answer can be obtained. It is easier to read graphs when the point of intersection does not occur at integer values.
B.
Graphing is the only method that would be appropriate to use here because it is not possible to use the substitution method if both equations are in​ slope-intercept form.
C.
Substitution is the only method that would be appropriate to use here because it is not possible to use the graphing method if both equations are in​ slope-intercept form.

In my honest opinion, I would say D. B and C don’t make much sense to me, and I don’t believe A is correct either. So yeah, I’d say D.

D. Graphing and substitution are appropriate to use if the answer involves integer values.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, a system of equations in​ slope-intercept form y₁ = m₁x₁ + b₁ and

y₂ = m₂x₂ + b₂.

We can use both substitution and graphing depending on the numerical values of the variables.

If the solution involves integer numbers, graphing and substitution are the proper methods to utilize. Substitution would be more effective since an accurate solution may be reached if the solution involves values that are not integers. If the intersection point doesn't have integer values, it can be challenging to understand graphs, so using this approach to solve would be ineffective.

If 120% of a is equal to 80% of b, then what is the value of a+b in terms of a and b?

Answers

120% of a
80% of b

120% = 120/100 =1.2
80%= 80/100 = 0.8

1.2a=0.8b | ÷1.2
1a = 2/3 b

1.2a=0.8b | ÷0.8
1b=1.5a


(a+b) = ((2/3b)+ (1.5a)) =2/3b + 1.5a
*not 100% sure

Answer:

120/100 a = 80/100 b

12/10 a = 8/10 b

10 (12/10) a = 10 (8/10) b

12a= 8b

3a= 2b

a+b in terms of a

b = 3/2×a

a+ 3/2×a = 5/2×a

a+b in terms of b

a = 2/3×b

b + 2/3.b = 5/3×b

Mai started a new exercise program. On the second day, she walked 5 minutes more than on the first day. On the third day, she increased her walking time from day 2 by 20% and walked for 42 minutes. Mai drew a diagram to show her progress.

Answers

Answer:

d = 30 minutes.

day one is equal to 30 minutes

day two is equal to 35 minutes

day three is equal to 42 minutes

Explanation:

The first step is to figure out how much day 2 was worth in total.

Using the model, we can see that 5 of the boxes from day three is equal to day 2.

42/6=7.

One of the boxes equals 7 minutes.

Next we find what all 5 of them equal.

7*5=35.

Day two was worth 35 minutes in total.

The next step is to figure out what d equals. In order to do that, we need to solve the equation:

d + 5 = 35.

subtract 5 from both sides.

d = 30.

Now we know that day one/D is equal to 30 minutes.

Day one: 30 minutes

Day two: 35 minutes

Day three: 42 minutes.

Hope that this is what your looking for. Have a good day and good luck!
