Answer:
5.6 = AC
Step-by-step explanation:
We know that the length of BD is congruent to the length of AC, therefore we can say:
<em>BD ≅ AC</em>
4.8 * 1.6 = 3.2 * x
7.68 ≅ 3.2x
7.68 / 3.2 ≅ x
2.4 = x
Therefore length of AC would be:
<em>3.2 + x = AC</em>
3.2 + 2.4 = AC
<u>5.6 = AC</u>
Hope this helps!
20 and 2/3 is correct, I think
Answer:
2 × 10 to the fourth power. (160,000)
Step-by-step explanation:
We know that if it is a negative exponent that is also an odd number, it will not be the greatest/largest. 2 times 10 is 20 and then 20 to the fourth power is 160,000. 3.8 times 10 equals 38, then we put it to the third power and we will get 54,872. Finally, 7.5 times 10 equals 75 and when we put that to the third power, it becomes 421,875. Therefore, 2 times 10 to the fourth power is the greatest/largest.

Answer:
x≥9
Step-by-step explanation:
Pretend the Less than or equal to sign is just an equals sign
-7x+7=-56 Solve:
-7x=-56-7
-7x=-63
For the last step, if you divide a negative number, the Sign switches. So not the sign is greater than or equal to.
x>=9
