Answer:

(5 x 6)x(3 x 2) is equal to 180

To find the answer, you have to solve them to see if they are equal to 180.

A) (5 + 6) + (3 + 2)    NO

simply cannot work because it's an addition of small numbers. This expression equals 16. Not equivalent.

B) (5 + 6) (3 + 2) (5 x 6) + (3 x 2)  NO

B doesn't make sense as it includes both the expressions together, including the initial expression which we are trying to find an equivalent answer, hence, it is going to equal more than the answer:  x > 180.  Solving for x is unnecessary as we know it is more.  

<u>No C? </u>

D) (3 x 2)x(5 x 6)  YES

This one works as the same numbers as the initial expression are equivalent and the expression uses the same math signs. This displays the commutative property of multiplication

Conclusion:

the Answer is D)

Two trains travel toward each other from points which are 195 miles apart. They travel at rate of 25 and 40 miles an hour respec
Tems11 [23]

Answer: it will take 3 hours for both trains to meet.

Step-by-step explanation:

Let t represent the time it will take for both trains to meet.

The two trains travel toward each other from points which are 195 miles apart. It means that after t hours, the total distance that both trains would have covered is 195 miles.

Distance = speed × time

Distance covered by the first train after t hours is

25 × t = 25t

Distance covered by the second train after t hours is

40 × t = 40t

Therefore,

25t + 40t = 195

65t = 195

t = 195/65

t = 3 hours

Right answer gets BRAINYESST
Mariulka [41]

Answer:

check all below

Step-by-step explanation:

#1

1/6)^3

1/26 so answer 1 on number one

#2 what the heck is this 65+75= 140 not 120

65/120 = 54.16666% * 12600 = 6825 so 3

or 65/140 = 46.428% * 12600 = 5850

#3 number 4 makes the most since sense you get the WHOLE POPULATION

#4 1/5*1/2 or 1/10 = .10 * 100% = 10% or 3

#5

6+2+8+4 = 20

2 red marbles

2/20 = 1/10 = .10 * 100% = 10% or 2

MZ3 = 64<br>m_4 = 106°<br>and<br>4<br>2<br>3<br>1<br>What is<br>mZ1,​
ddd [48]

Answer: m∠1=42°

Step-by-step explanation

For this problem, we can separate the triangle into 2 separate triangles to solve for m∠1.

We know that m∠4 is 106°. ∠2 and ∠4 are supplementary angles. You can see that they make a straight line of 180°. We can use this fo find ∠2.

∠2+∠4=180

∠2+106=180

∠2=74°

Now that we know ∠2 is 74°, we can use that to solve for m∠1.

We know that the measures of the angles in a triangle equal to 180°. For the triangle at the bottom, we see ∠3, ∠2, ∠1. Since we know ∠3 and ∠2, we can find ∠1.

∠3+∠2+∠1=180

64+74+∠1=180

138+∠1=180

∠1=42°

The answer is 24.5 by rounding off nearest tenth it becomes 25
PROCEDURE:
1: put all the numbers in numerical order i.e.22,23,24,24,25,26,28,29;
2:now the total amount of values is even, so the median will be the mean of two central values i.e. 
(24+25)/2=24.5
now by rounding it off to nearest tenth it becomes 25
