Answer: 54 lattes were sold
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations with the information given:
If each latte costs $4 , each cappuccino cost $3, and sales totaled $252:
4 x + 3y = 252
Where
x = number of lattes
y = number of cappuccinos
The number of lattes sold was 6 more than 4 times the number of cappuccinos. Mathematically speaking:
x = 4y +6
Now, we have the system:
a)4 x + 3y = 252
b)x = 4y +6
Replacing the value of x in a) for b):
4 (4y +6) +3y =252
16y +24 +3y =252
16y +3y =252 -24
19y = 228
y= 228/19
y = 12
Replacing the value of "y” in b ) for the value obtained:
b)x = 4y +6
x = 4 (12) +6
x = 48+6 = 54
x =54
So , 54 lattes were sold.
Answer:
C.
Step-by-step explanation:
First, isolate the y:
First, since there is no "equal to", we can ignore B and D since their lines are shaded.
Since the y is greater than, we need to pick the graph that is shaded above the line.
The answer is C as the shaded portion is above the graph and the graph is dotted.
Answer:
should be -7.5
Step-by-step explanation:
4.9×5=24.5
17-24.5=-7.5
So, the fee is 125 and...
125+
a certain fee "x"
125+x*
which is paid monthly, that is 12 times:
125+x*12
and this equals 720.
125+x*12=720
subtracting 125:
x*12=595
dividing by 12:
x=49,58
and this is how much they pay each month!
Answer:
Let L = length
Let w = width
Perimeter = 2L + 2w
L = 100
Perimeter > 400
2(100) + 2w > 400
200 + 2w > 400 is the inequality
Subtract 200 on both sides of inequality.
2w > 200
w > 100
The width is at least 100 centimeters
