Answer:
Lisa bought 9 gallons of ice cream
Step-by-step explanation:
lets take "x" as the gallons of lemonade
if Lisa made purchases worth $34 that is what our equation will e equal to
ice cream:7.5 per gallon
milk: 2.5 per gallon
lemonade: 3 per gallon
since Lisa purchases 4 gallons of milk and 2 gallons of ice cream we will multiply that by the unit money for each food respectively:
7.5(2)+2.5(4)+X=34
SIMPLIFY:
15+10+x=34
15+10=25
25+x=34
25-25+x=34-25
x=9
Lisa bought 9 gallons of ice cream
hope this helps!
Start by subtracting 2 from both side which gives you [-3x<9] then divide by -3 which gets you [x<-3] so the answer is B
Answer: 3.96 pints
Step-by-step explanation: if 3/5 is blue, then 2/5 has to be white (since 3/5 + 2/5 = 1). Multiply 9.9 by 2/5 to get 3.96 pints
Answer:

Step-by-step explanation:
<u>slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept
Given line: y= 2x +2
slope= 2
The product of the slopes of perpendicular lines is -1. Let the slope of the unknown line be m.
m(2)= -1
m= -1 ÷2
m= -½
Substitute the value of m into the equation:
y= -½x +c
To find the value of c, substitute a pair of coordinates.
When x= 4, y= 3,
3= -½(4) +c
3= -2 +c
c= 3 +2
c= 5
Thus, the equation of the line is y= -½x +5.
