Answer:
no solution
Step-by-step explanation:
-6 * 8= -48
-3 - 48= -6 - 8
-51 = -14
it is no solution because the numbers are not the same
Answer:
x = 12
Step-by-step explanation:
Let's use the distributive rule first for both 5(x - 1) and 7(x + 1). When using the distributive rule to expand parentheses, remember to find the sum of the product of the "outside number" with each of the "inside numbers".
5(x - 1): 5 is the outside number and both x and -1 are the inside numbers.
5 * x + 5 * (-1) = 5x - 5
7(x + 1): 7 is the outside number and both x and 1 are the inside numbers.
7 * x + 7 * 1 = 7x + 7
Now, we can put these back into the equation:
5x - 5 + 3x = 7x + 7
Combine all the x's and the constants:
8x - 5 = 7x + 7
x = 7 + 5 = 12
Thus, the answer is x = 12.
Hope this helps!

In the equation L=0.8T², we will substitute 30 for L:
30 = 0.8T²
Divide both sides by 0.8:
30/0.8 = 0.8T²/0.8
37.5 = T²
Take the square root of both sides:
√37.5 = √T²
6.1 = T
