I think D too because that one is the only one that makes sense
Answer:
35
Step-by-step explanation:
Answer:
Step 2: He should have added 3 to, rather than subtracting 3 from, both sides.
Step-by-step explanation:
1. Combine like terms: 6b − 3 = −21
2. Subtraction property of equality: 6b = −24
Here he has to add 3 on both sides, to isolate the variable term.
Therefore, answer is Step2) He should have added 3 to, rather than subtracting 3 from, both sides.
Hope this will helpful.
Thank you.
Rewriting the function we have:
p = 9200 / D
We must in this case clear the value of D.
We have then:
D = 9200 / p
Substituting the value of p = 1600 lb we have:
D = 9200/1600
D = 5.75 feet
Answer:
the distance between supports that is needed to carry 1600 lb is:
D = 5.75 feet
