Answer:
If the equation ends with a false statement (ex: 0=3) then you know that there's no solution. If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.

Answer:
I can see how this is confusing, because of -2, but the slope is decreasing, so the question wouldn't say:
[tex]-3/5x - -2[/tex]
This happens to turn the -2 into a regular 2 with an addition (+) sign.
and since the graph has an input of 5 but an output of -3, the equation would be:
y = -3/5x + 2
Dan charges a fixed amount per hour. He charges £180 for a job which takes 12 hours. Work how much he will charges for a job which will take 18 hours.
Answer:
270 pounds
Step-by-step explanation:
half of 12 is 6, so 18. Then you take half of 180 and add to 180
Answer:
18 hours = £270
Step-by-step explanation:
Find how much he charges per hour. Divide:
[tex]\frac{180}{12}=15[/tex]
So ha charges about 15 an hour. Multiply this price by the number of hours:
[tex]15*18=270[/tex]
Therefore, he will charge £270 for a job that takes 18 hours.
OR
Set a proportional relationship since he charges a fixed amount:
[tex]\frac{price}{time}=\frac{price}{time}[/tex]
Insert the appropriate corresponding values:
[tex]\frac{180}{12} =\frac{x}{18}[/tex]
Solve for the price after 18 hours of work, represented by x. Cross multiply:
[tex]12(x)=180(18)\\\\12x=3240[/tex]
Solve for x. Use inverse operations to isolate the variable. Divide both sides by 12:
[tex]\frac{12x}{12} =\frac{3240}{12} \\\\x=270[/tex]
Therefore, after 18 hours, he will charge £270.
:Done

1.The ratio of males to total students in a mathematics class is 12 to 30. What fraction of the class is male?
40/10
6/10
12/30
2/50
The ratio of males to total students in a mathematics class is 3 to 30. What percent of the class is male?
40%
10%
45%
12%
Answer: 12/30
and 40 percent
Step-by-step explanation:
Well it’s 12 to 30 so just put a fraction bar
and 12 divided by 30 is .4
Answer:
The answers are 12/30 and 10%
Step-by-step explanation:
It's 40% because the ratio of males to total students is 12 to 30, or 12:30, which is equal to 12/30.
The other answer is 10% because the ratio of males to total students is 3 to 30, or 3:30, which is equal to 1/10. Then you would do 100 divided by 10 which would give you 10 so it's 10%.
Hope this helps!
Pls Answer this using Algebraic expressions
Answer:
a) A total of 27 parents will receive a call on the third round of calls. b) A total of 39 parents would've been called by the end of the third round of calls. c) There would have to be a total of between 5 and 6 rounds
Step-by-step explanation:
Every time the total number of parents call 3 people, the number of parents tripled in every round.
3 to 9 to 27 to 51 to 153 to 459
Since 153 and 459 are between 5 and 6 rounds, the phone calls will stop between those 2 rounds.
