20x1/4=5
Think thats what you mean
Answer:
0.4(−0.45)=9.2
2(−0.45)5=9.2
Step-by-step explanation:
=23.45
P= a+b+c = 76
side a = 2b = 30
side b = b = 15
side c = 2b + 1 = 31
Answer:
for four copies the cost is $72
Step-by-step explanation:
52 + 5a = 24 + 12a
28 + 5a = 12a
28 = 7a
a = 4
52 + 20 = 72
for four copies the cost is $72
(688-684) x 222
You have to do what’s in the parentheses first because of PEMDAS
688-684=4
Then you have to multiply
4x222
=888
