Answer:
n=3
Step-by-step explanation:
5n+3=18
subtract 3 from both sides
5n=15
divide by 5 on both sides
n=3
Answer:
n=3
Step-by-step explanation:
step 1- subtract 3 to both sides
+3-3=0 18-3=15
5n=15
step 2- divide both sides by 5
5÷5=1 15÷5=3
step 3- check answer by plugging in for n
5(3)+3=18
15+3=18
18=18

Actually Welcome to the Concept of the Mathematics.
Applying the simple squares of 7 and 8.
7*7= 49 and 8*8=64
hence square root 58 is more than 7 but less than 8
hence we get as,

rick believes the two expressions 4(3a-3) +2a and 14a-3 are equivalent. is he correct? explain why or why not?
Answer:
no
Step-by-step explanation:
4(3a-3)+2a when you expand youget
((4x3a)-(4x3)) + 2a = 12a - 12 + 2a then we collect the like term first 12a + 2a - 12
14a -12
therefore 14a - 12 is not equal to 14a- 3

Describe what a finite graph is and give an example of how a finite graph would be used to represent something.
Answer:
A graph with a set amount of numbers.
Step-by-step explanation:
Infinite means never ending and that's what most graphs are. But, a finite graph is a graph that doesn't have arrows at the end of the lines. (simplified answer) A better way of saying it is a graph with a fixed starting position and a fixed ending position. You can use this type of graph if you don't want to go over or under a certain value.

Glen purchased tickets= 4
total cost of tickets alone = 54*4 =£216
now calculation of the 5% tax of the tickets,
5/100 * 216 = £ 10.8
hence the total amount Glen has to pay is
=> 216+10.8 = £226.8

Cole has already taken 7 quizzes during past quarters, and he expects to have 1 quiz during each week of this quarter. Write an equation that shows the relationship between the number of weeks x and the total number of quizzes y.
Answer:
y = x + 7
Step-by-step explanation:
x = number of weeks
y = the total number of quizzes y.
Cole has already taken 7 quizzes = + 7
he expects to have 1 quiz during each week of this quarter = 1x
y = 1x + 7
y = x + 7

Answer:
[tex]\frac{11}{6} y[/tex]
Step-by-step explanation:
Since they all have y as the variable, you can simply add the coefficients (number in front of the variable) together. (y = 1y)
[tex]\frac{2}{3} + \frac{1}{6} + 1 = \frac{4}{6} + \frac{1}{6} + \frac{6}{6} = \frac{11}{6}[/tex] or [tex]1\frac{5}{6}[/tex]

Samir had 30 dollars to spend on 3 gifts. He spent 9
9
10
dollars on gift A and 5
3
5
dollars on gift B. How much money did he have left for gift C?
Answer:
Gift 1 ($9) Gift 2 ($10)
Step-by-step explanation:
First we know that Samir had 30 dollars to spend on 3 gifts. If he bought gift 1 for $9, and gift 2 for $10. Then Samir should have $11 for gift 3 that he can spend.
9+10=$19, $30-19=$11 Hope This helps! Mark Brainllest if it is correct!
Hence, the money did he have left for gift C is [tex]15.5[/tex].
What is the simplification?
Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter), for example Simplification of a fraction to an irreducible fraction.
Here given that,
Samir had [tex]30[/tex] dollars to spend on [tex]3[/tex] gifts. He spent [tex]9.\frac{9}{10}[/tex] dollars on gift A and [tex]4.\frac{3}{5}[/tex] dollars on gift B.
So,
[tex]A=9.\frac{9}{10}\\\\A=\frac{90+9}{10}\\\\A=\frac{99}{10}\\\\A=9.9[/tex]
[tex]B=4.\frac{3}{5}\\\\B=\frac{20+3}{5}\\\\B=\frac{23}{5}\\\\B=4.6[/tex]
To find out the money did he have left for gift C is
[tex]A+B+C=G[/tex]
Here,
[tex]A=9.9\\B=4.6\\G=30[/tex]
Then,
[tex]9.9+4.6+C=30\\\\C=30-9.9-4.6\\\\C=30-14.5\\\\C=15.5[/tex]
Hence, the money did he have left for gift C is [tex]15.5[/tex].
