Answer:
Step-by-step explanation:
4.5b + 8.5c = 175
b + c = 22.......b = 22 - c
4.5(22 - c) + 8.5c = 175
99 - 4.5c + 8.5c = 175
-4.5c + 8.5c = 175 - 99
4c = 76
c = 76/4
c = 19......there are 19 cats
b + c = 22
b + 19 = 22
b = 22 - 19
b = 3 <==== there are 3 birds
Answer:
x=8
Step-by-step explanation:
The factors of the expression is 2and -3
Answer:
a) 7 + (-4) = 3
b) (-6) + (-3) = -9
c) 2 -(-6) = 8
d) (-8) - (-13) = 5
Step-by-step explanation:
a) 7 + (-4)
= 7 + (-4)
= 3
b) (-6) + (-3)
= -6 - 3
= -9
c) 2 - (-6)
= 2 + 6
= 8
d) (-8) - (-13)
= -8 + 13
= 5
