Answer:
17=s+7
-7 -7
-----------
10 0
s=10
Step-by-step explanation:
-Subtract 7 from both sides
-Remove the 0 and the addition sign
-You are now left with the equation s = 10
-Once you check to make sure 10 + 7 = 17 you have your answer
Hope this helps :))
Hey!
-------------------------------------------------
This just shows to substitute all of x with -1.
g(-1) = 3(-1) - 5
g(-1) = -3 - 5
g(-1) = -8
-------------------------------------------------
Hence, the answer is -8!

Hope This Helped! Good Luck!

Given Information
-------------------------------------------------------------------------
Total number of people = 165
Adult = $6
Child = $2
Total collected = $618
-------------------------------------------------------------------------
Assumptions
-------------------------------------------------------------------------
Let x be the number of adults and y be the number of children
-------------------------------------------------------------------------
Form equations
-------------------------------------------------------------------------
Total number of people
x + y = 165
Total amount collected
6x + 2y = 618
-------------------------------------------------------------------------
Ans: The two equations are x + y = 165 and 6x + 2y = 618
-------------------------------------------------------------------------
The question is not asking for it but if you need to solve the equation to find the answer to x and y
-------------------------------------------------------------------------
Present the two equations and solve for x and y
-------------------------------------------------------------------------
x + y = 165 ------------------------- (eqn 1)
6x + 2y = 618 ------------------------- (eqn 2)
(eqn 1) :
x + y = 165
x = 165 - y ------------------------- substitute into (eqn 2)
6(165 - y) + 2y = 618
990 - 6y + 2y = 618
4y = 990 - 618
4y = 372
y = 93 ------------------------- substitute into (eqn 1)
x + y = 165
x + 93 = 165
x = 165 - 93
x = 72
x = 72 and y = 93
-------------------------------------------------------------------------
Ans: 72 adults and 93 children
-------------------------------------------------------------------------
Answer:
c=18
Step-by-step explanation:
54 divided by 9 is 6
6 times 3 is 18
Answer:
Choice C is the correct answer.
Step-by-step explanation:
Given expression is
(3p-7)(2p²-3p-4)
we have to find the product of linear expression to quardatic expression.
Firstly, multiply 3p to quardatic expression and -7 to quardatic expression and add.
3p(2p²-3p-4)-7(2p²-3p-4)
Multiply 3p to each term of quardatic expression and -7 to each term of quardatic expression and add all terms:
3p(2p²)+3p(-3p)+3p(-4)-7(2p²)-7(-3p)-7(-4)
6p³-9p²-12p-14p²+21p+28
add like terms
6p³+(-9-14)p²+p(-12+21)+28
6p³-23p²+9p+28 which is the correct answer.
