Answer:
1
Step-by-step explanation:
Given that both equations are equal, solve the distributive property and then just solve for X:
2x + 2(3x-1) = 3(x+1)
2x + 6x - 2 = 3x + 3
5x = 5
x = 1
Therefore, the value of X is 1.
To know the perimeter of the triangle, we apply the value of X to solve the equation.
3(x + 1)
3(1 + 1)
3 + 3 = 6.
Therefore, each figure's perimeter is 6, as both are equal.
Make a common denominator, which could be 10. so, to make the first numbers denominator equal, you multiply it by 2. Then you also have to multiply the top number by 2. So, 3/5 = 6/10, which is less than 7/10
Answer:
180
Step-by-step explanation:
80 + 100 = 180
Mark me brainliest :)
First number = X
Second number = 8X
Third number = X - 3
The equation would be
X + (8X) + (X - 3) = 207
X + (8X) + (X - 3) = 207
X + 8X + X - 3 = 207
10X - 3 = 207
10X = 207 + 3
10X = 210
X = 21
First number = 21
Second number = 8 * 21 = 168
Third number = 21 - 3 = 18
In the equation 3.4a = 57.8, a is equal to: 17.
