Explain how you could use the distributive property and mental math to find 5x198
1 answer:
You have to break up the number into hundreds, tens, and ones then add their products together
5*100=500
5*90=450
5*8=40
500+450+40=990
5*198=990

Answer:
A
Step-by-step explanation:
9 = (1/27)^(a+3)
3² = (3^-3)^(a+3)
3² = 3^(-3a-9)
2 = -3a-9
-3a = 11
a = -11/3
129 is 249 degrees warmer than -120 because -120+120=0 and then you add 129 to 0 which is 129. that means you add 120 and 129 to get 249
You would do
51-5= 46
then you would divide
46/2= 23
so Susan is
23+5=28
Susan is 28 years old and her sister is 23
28+23=51
