4(3+x)
This is because 4*3=12 and 4*x is 4x so you get 12+4x which is the original equation
Answer:
Vota Trump
Step-by-step explanation:
Only two of them are the correct answers to this question.
Answer:
9 tens = 90
5 hundreds = 500
3 ones = 3
on adding them we get, 500 + 90 + 3 = 593
X=price of one jumbo popcorn
y=price of one chocolate chip cookies
$5.00=$5.00(100 cts / $)=500 cts
$6.00=$6.00(100 cts / $)=600 cts
We suggest this system of equations:
x+2y=500
x+4y=600
we solve this system of equations by reduction method.
-(x+2y=500)
x+4y=600
----------------------
2y=100 ⇒ y=100/2=50
x+2y=500
x+2(50)=500
x+100=500
x=500-100
x=400
solution: one chocolate chip cookie cost 50 cts.
