Answer:
3. -7/5 x ( 4/5 + 9/15)
-7/5( 4/5 ) + -7/5 (9/15)
-28/25 + -21/25
- 49/25
4. x + y = 17
+x - y = 1
2x = 18
x = 9
9 - y = 1
y = 9 - 1
y = 8
the two digit number is 10x+y
10(9) + 8
98
5. volume of a cube = a^3
given volume = 10.648
a^3 = 10.648
a = [tex]\sqrt[3]{10.648}[/tex]
a = 2.2 ( approximately)
