If u work it out and both sides don't equal, then there is no solution.
Example :
2x + 4 = 2x + 6
2x - 2x = 6 - 4
0 = 2....this is incorrect...therefore, there is no solution
To how many sig figs or decimal places? Could use 1735 if rounded to 2 significant figures (2sf)
Based on the information about side JK = side JL, then we know it is at least an isosceles triangle. Furthermore, ∡K =∡L because they are the base angles in an isosceles triangle.
Equation: 4x - 1 = 9x - 31
Solved: x = 6
Angle measures: ∡J = 23(6) - 4 = 138 - 4= 134
∡K = ∡L = 23
Answer:
50
Step-by-step explanation:
Assuming you're solving for Q, the first step is to multiply the first set of parenthesis by 0.10:
0.10(72-Q) = 7.2 - 0.1Q
The next step is to combine the terms that have Q in them:
7.2 - 0.1Q + 0.25Q = 14.7
7.2 + 0.15Q = 14.7
Now isolate 0.15Q:
0.15Q = 14.7 - 7.2
0.15Q = 7.5
Divide 7.5 by 0.15 to solve for Q:
Q = 7.5/0.15 = 50
Answer:
7800 is your surface area
Step-by-step explanation:
5 x 12 x 10 x 13= 7800
