The number is composed by two digits, let them be ab, so we have:
a + b = 11
this is a pseudo-equation, we are not multiplying ab or ba, is just the digits order.
ba = ab + 9
The pairs of numbers that could comply with the first equation are:
(2,9)
<span>(3,8)
</span><span>(4,7)
</span><span>(5,6)
</span>But only the last couple <span>(5,6) comply as well with the second condition. Because 65 = 56 + 9
Therefore the unknown number is 56</span>

Answer:Enrqiue's average was higher than Rosario's average by 3
Step-by-step explanation:
Rosario's average= sum of 78, 77, 64, 86, and 70/ no of scores= 375/5= 75
Enrique's average=sum of 90, 61, 79, 73, and 87/ no of scores = 390/5=78
78-75=3
Answer:
Because the Length is 5 times the width, L(length) = 5w. You can use this information to update your perimeter.
P= L + W
P= 5w + w = 6w
P = 120, 120= 6w
120/6 = 6w/6
20 = w
L = 5w, L = 5(20) = 100
A = L x W, 100 x 20 = 2000
This means 2000 is the area
