Start by getting all terms with x on one side and all terms without on the other.
6x+7=8x-15
subtract 6x from both sides
7=2x-15
add 15 to both sides
22=2x
divide both sides by 2
11=x
Answer:
The answer is 3
Step-by-step explanation:
Step-by-step explanation:
We can prove KK'M and LL'M are congruent by using ASA (Angle side angle). Angle side angle means that if we know two angles and one side, we can prove that they are congruent.
First, we know that ∠KMK' = ∠LML' because they are alternative angles. (That's our fist A)
Next, The problem states that KK' and LL' are equal. (so that gives our S)
Finally, we know that ∠ML'L and ∠KK'M are both 90 degrees, making them both equal. (That's our final A)
Hope this helped :D
30. is 8 [-5] [3] [-2] -2
Step-by-step explanation:
step 1. a 30 - 60 - 90 triangle has side lengths 1 - sqt(3) - 2
step 2. x = sqr(3)*10 = 10sqr(3)
step 3. y = 2*10 = 20
step 4. n = 3sqr3/sqr3 = 3
step 5. m = 2n = 2*3 = 6.
