Answer:
1/5x - 12 = -7
Step-by-step explanation:
The first thing says 12 less THAN. Normally, when you see something in word problems like "less than" it means you need to switch the places.
So rather than 12 - 1/5, it's 1/5 - 12.
1/5 of a number means you are multiplying that number by 1/5. we'll use x (or any letter really, doesn't matter) to represent the unknown number.
Remember that if a variable and number is written together, it means multiplication.
So, 1/5x - 12 = -7.
Step-by-step explanation:
Answer is in the pic above
See,u have y+5x=6 ( * =multiplication sign)
and x=-1,0,1
so ,u have to do is substitute x with numbers u have
so,for -1,u have y+5*-1=6
=y= 5+6= 11 ( u multiply 5 by -1 u get -5 but when u change the sides u get it as 5 ...so 5 + 6 =11)
(2)y+5*0=6
=y=6-0=6
(3)y +5*1=6
y=6 -5=1

STEP 1
Multiply total number of customers by percent who made a purchase.
= 950 customers * 82%
= 950 * 0.82
= 779 customers made a purchase
STEP 2
Subtract the number of customers who bought one and two items from the total number of customers who made a purchase.
= 779 - 538 - 186
= 55 customers purchased 3 or more items
ANSWER: 55 customers purchased 3 or more items.
Hope this helps! :)
Answer:
First account= 2500
Second account= 4000
Step-by-step explanation:
Total amount invested: 6500
Amount in first account: x
Amount in second account: y
x+y=6500
1.13x+0.9y=6500-75=6425
You have two equation now just solve the system of equation through either substitution or elimination.
Then you'll get the answer
x= 2500
y= 4000
