Answer:
x= 2.5
Step-by-step explanation:
We can use ratios to solve
AB AD
------- = ----------
AC AE
X 5
------- = ----------
x+1 7
Using cross products
7x = 5(x+1)
Distribute
7x = 5x+5
subtract 5x
7x-5x = 5x-5x+5
2x= 5
Divide by 2
2x/2 = 5/2
x = 2.5

Step-by-step explanation:
The hundredth is the second number to the left of the decimal point. To round you use the number to the left to judge whether the next number will go up or down.

Step-by-step explanation:
Using the rule of exponents
× ⇔
49
3b × 4b³ = (3 × 4) × = 12
50
5x² × 8x × 5x³
= (5 × 8 × 5) × = 200
