Answer:
Step-by-step explanation:
Total cost for the three nights
Total_3 = $298.17 + 3*u
Where <em>u </em>represents the unknown fees for a single day
To find the daily cost, we divide the previous equation by three
Daily cost = ($298.17 + 3*u)/3
Daily cost = ($99.39 + u)
So, if we create an inequality for the daily cost
Let x = Daily cost
x > $99.39
She will pay more than $99.39 per night
Answer:
a. 8 years
b. $49.20
Step-by-step explanation:
The computation is shown below:
a. The mark age is
Given that
232 is 8 times of the sum of mark and his sister ages
And, his sister is 21
So,
Let us assume the mark age be x
now
8(x + 21) = 232
x + 21 = 29
x = 29 -21
x = 8
b. The original price of the socks is
As each pair get $3 off
And she bought 6 pairs for $31.20
= $31.20 + 6 × $3
= $31.20 + 18
= $49.20
100-25=75
find 75% of the 85
percent means parts out of 100
75%=75/100=0.75
'of' means multiply
75% of 85 means
0.75 times 85=63.75
sale price is $63.75
1 quart= 2 pints so 31 pints = 15.5 quarts so 15.5+13=23.5-20= 3.5 left hope this explains it better!!
Answer:
3 inches and 9 inches
Step-by-step explanation:
Area of a trapezoid is given by
A = 1/2 (b1+b2)*h where b1 and b2 are the lengths of the bases
b1 =b
b2 =b1+6 = b+6
h =6
A = 36
Substituting in what we know
36 = 1/2 (b+b+6)*6
Simplifying
36 = 3 (2b+6)
36/3 = 3/3 (2b+6)
Divide each side by 3
12 = 2b+6
Subtract 6 from each side
12-6 =2b+6-6
6 =2b
Divide each side by2
6/2 =2b/2
3=b
b1 =b =3
b2 =b1+6 = b+6 = 3+6 =9
One base is 3 and the other is 9
