Answer:
Step-by-step explanation:
x + 25 + 4x + 10 = 180
5x + 35 = 180
5x = 145
x = 29
<1 = 29 + 25 = 54
<2= 4(29) + 10 = 116 + 10 = 126
Answer:
4.The product is greater that 3/8 and less than 7/2.
Step-by-step explanation:
The product of 3/8 and 7/2 is:

This number is greater than 3/8.
It is greater than 1/8 but not less than 1/2.
This number is less than 7/2.
This number is greater than 3/8 and it is less than 7/2.
Hence, the correct options is 4.
A = b+5
ab = 3300
(b+5)b = 3300
b² +5b -3300 = 0 (quadratic formula)
b=55
a=60 (by first relation)
Answer:
A.
