The triangles area would be 3 x 4 = 12 / 2 = 6.
The perimeter would be 12.
-3/4 + 2/5 x = 7/20 x - 1/2
2/5 x = 7/20 x - 2/4 + 3/4
2/5 x = 7/20 x + 1/4 (first option - Yes)
second option - No
-3/4 + 2/5 x = 7/20 x - 1/2
-3/4 = 7/20 x - 8/20 x - 1/2
-3/4 = -1/20 x - 1/2 (third option - Yes)
-3/4 + 1/20 x = -1/2 (fifth option - Yes)
fourth option - NO
Answer:
2/5 x = 7/20 x + 1/4 (first option)
-3/4 = -1/20 x - 1/2 (third option)
-3/4 + 1/20 x = -1/2 (fifth option)
Answer:
Given equation: 2(x+7) = 36. ......[1]
Distributive Property of multiplication states that when a number is multiplied by the sum of two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately i.e,
![a \cdot (b+c) =a\cdot b+ a\cdot c](https://tex.z-dn.net/?f=a%20%5Ccdot%20%28b%2Bc%29%20%3Da%5Ccdot%20b%2B%20a%5Ccdot%20c)
Then,
By using the distributive property in equation [1];
2(x+7) = 36
![(2 \cdot x) + (2 \cdot 7) =36](https://tex.z-dn.net/?f=%282%20%5Ccdot%20x%29%20%2B%20%282%20%5Ccdot%207%29%20%3D36)
Simplify:
![2x+14=36](https://tex.z-dn.net/?f=2x%2B14%3D36)
Divide both sides by 2 in above equation:
![\frac{2x+14}{2} =\frac{36}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%2B14%7D%7B2%7D%20%3D%5Cfrac%7B36%7D%7B2%7D)
Simplify:
x+7 = 18.
Therefore, the first correct step would be option B,
after that the next step would be option A then option F as shown above;
Remaining options are not enough information to solve the given equation 2(x+7) = 36.
Answer:
14
Step-by-step explanation:
40 plus 2 is 42
42 divided by 3 is 14
The numerical expression for the verbal expression is 18 ÷ (2+7).
Given,
Verbal expression = Eighteen divide by the sum of two and seven
we know that ,
We can write any verbal expression to numerical expression by using playing with numbers.
Playing with numbers:
Playing with numbers involves activities like arranging the numbers, understanding , finding out whether a given number is a factor of another number or a multiple of another number, and understanding the properties of factors and multiples
Now, According to question
Eighteen divided by the sum of two and seven
18÷(2+7)
Therefore,
The numerical expression is 18÷(2+7).
