Answer:
56.8
Step-by-step explanation:
Ratios.
42------60
1----------1.42
40-------56.8
First, divide 42 by 42 which is one. Then, divide 60 by 42, which is 1.42.
Next, multiply 1 by 40. Finally multiply 1.42 by 40 which is 56.8. Hope this helps
71,400,000 In Scientific Notation:
71,400,000 = 7.1400000 < 10
7.14 x 10^7
Answer:
20
Explanation:
To estimate, we round. 102.3 rounds to 100 and 4.7 rounds to 5; this means we divide 100/5, which is 20.
If you meant 2x + 2x + 1 = 17: x = 4
Solve for x by simplifying both sides of the equation, then isolating the variable.<span>
</span>
If you meant <span>x2 + 2x + 1 = 17:</span> <span>x ≈ 3.1231056,−5.1231056x</span>
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula. <span><span>x = −1 ± <span>√17</span></span>x</span>
D. because when you multiply you move your numbers to the left and 1000 has 3 zeros meaning you will move your answer 3 times to the left .
hope you understand
good luck with your homework
