Q)You are going to movies Friday night. which of the theaters will cost the least, if you intend to have soda and popcorn?
Theater A Theater B Theater C
Adults $6.25 $7.25 $5.25
Children $3.50 $3.75 $4.25
Soda $2.00 $2.00 $2.50
Popcorn $2.50 $2.00 $2.50
Answer:
Theater B will cost less.
Step-by-step explanation:
The question here does not tell how many adults and children are going so we will only calculate the price for soda and popcorn for the theaters above.
For Theater A:-
$2.00 + $2.50 = $4.5
For Theater B:-
$2.00 + $2.00 = $4
For Theater C:-
$2.50 + $2.50 = $5
Hence Theater B will cost less.
Times both sides by 18
18n/18=5/9*18
n(18/18)=90/9
n(1)=10
n=10
The correct answer is: [C]: "2" .

Explanation:
____________________________________________________
Assuming the problem in the question is:
→ " What is: log₁₀ 100 ? " ;
→ which, when 'read aloud' ; is: "What is log base ten of 100<span>" ?
</span>____________________________________________________
→ To solve:
____________________________________________________
→ " log₁₀ 100 = x " ; → Solve for "x" ;
→ 10ˣ = 100 ; Solve for "x" ;
→ that is; "10 raised to the "x th" power" = 100 " ; → Solve for "x" ;
→ The answer: "x = 2 " ;
→ {since: " 10² = 100" ; since: "10 * 10 = 100" } ;
→ log₁₀ 100 = " 2 " ; → which is: Answer choice: [C]: " 2" .

Answer:hopes this will helpp
Step-by-step explanation:In the same way, I will combine these two like terms by adding the numerical portion of each term, while carrying the x along for the ride: 3x + 4x. (3 + 4) x. (7) x.
Answer:
1- 1/3 x +3y=1
y=2/3 x-4
solution : x=39/7 , y=-2/7
3x-2y=11
-3x-y=4 solution x=1/3, y=-5
Step-by-step explanation:
1/3 x +3y=1
y=2/3 x-4
solve by substitution for y in the first equation:
1/3 x + 3(2/3 x-4)=1
1/3 x+6/3 x-12=1
7/3 x=12+1
7/3 x=13 ⇒7x=39 ⇒x=39/7=5 4/7
y=2/3 x -4
y=2/3 (39/7)-4
y=72/21 -4
y=-4/7
second problem:
3x-2y=11
-3x-y=4 solve by elimination: add two equation to eliminate x
3x-2y-3x-y=11+4
-3y=15
y=15/-3 ⇒y=-5
substitute y in one of the equations: 3x-2y=11
3x-2(-5)=11
3x+10=11
3x=11-10
x=1/3
