Step 1 : Simplify both sides
-5(6a+21)=-15
(-5)(6a)+(-5)(21)=-15
-30a-105=-15
Step 2 : Add 105 to both sides
-30a-105+105=-15+105
-30a=90
Step 3 : Divide both sides by -30
-30a=90
—————
-30 -30
a = -3
Answer:
1/3
Step-by-step explanation:
probability = favorable outcomes/total possible outcomes
There are two favorable outcomes, 2 and 5.
There are 6 total possible outcomes.
Make your fraction.
2/6
reduce
1/3
Step-by-step explanation:
27x² = 3*3*3*x*x
45x³y² = 3*3*5*x*x*x*y*y
Now
GCF = 3 * 3 *x * x = 9x²
It would be 1.276 x 10(5) the exponent is 5 next to the 10
