Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
(24)(x)=(83)(x)−10
Step 1: Simplify both sides of the equation.
(24)(x)=(83)(x)−10
16x=512x+−10
16x=512x−10
Step 2: Subtract 512x from both sides.
16x−512x=512x−10−512x
−496x=−10
Step 3: Divide both sides by -496.
−496x
−496

Answer:
C. 7 weeks.
Step-by-step explanation:
Since the shrub was 64 cm tall at first, take away 64 from 76.6. Now we are left with 12.6. Let's divide 12.6 by 1.8 (that's how many cm it grows per week). When we do this, we are left with 7. This means it took 7 weeks for the shrub to reach 76.6 cm. I hope this helps!
Answer:
The ratio of sides in a 30-60-90 triangle is 1:√3:2. Since the shortest side is the 1 in this case the other lengths are 15√3 and 30.
