Answer:
<u>The numbers are 12 and 32.</u>
Step-by-step explanation:
x = One number
x - 20 = Another number
3x - (x - 20) = 84 (If the lesser number is subtracted from three times the greater number, the difference is 84)
Let's solve for x, this way:
3x - (x - 20) = 84
3x - x + 20 = 84
2x = 84 - 20 (Subtracting 20 at both sides)
2x = 64
x = 64/2
<u>x = 32 ⇒ x - 20 = 12</u>
52.5cm^2
8x5 = 40
8-(1+2)=5
5x5=25
25/2=12.5
40+12.5=52.5
Answer:
The value of x taking denominator common is
Step-by-step explanation:
Given expression as :
=
or, - = 0
Or, - = 0 (multiply numerator and denominator by 5 )
Now taking denominator as common
Or, ( 3 - 5 x ) = 0
Or, = 0 and (3 - 5x ) = 0
∵ (3 - 5x ) = 0
So, 5 x = 3
∴ x =
Hence The value of x taking denominator common is Answer
Answer:
The minimum number of cups she must sell to reach her goal=43 cups
Step-by-step explanation:
Total earnings=Total Lemonade sales-Supplies expenditure
where;
Total earnings=$40
Total Lemonade sales=Price per cup×Number of cups sold(n)=(0.7×n)=0.7n
Supplies Expenditure=0.23 per cup=(0.23×n)=0.23n
Replacing;
40=0.7n+0.23n
Inequality; 0.7n+0.23n=40
Solving;
0.93n=40
n=40/0.93)=43 cups
The minimum number of cups she must sell to reach her goal=n=43 cups
