Answer:
835
Step-by-step explanation:
We know that the hundreds is 8 and the ones is 5 so the sum needed is 16-(8+5), which equals 3 :)
The answer is A
your expression said 5×20=100 +3×20=60 So 100+60=160
now the option A is5+3=8 then 8×20=160 there the same product
Answer:
4 nickels to 1 dime
Step-by-step explanation:
the steps are in the pic above I gotta get this to 20 characters bye!
I would subtract the 2nd from the first one
so -4x - -2x = -2x
4y - 4y = 0
-20 - -2 = -18
-2x = -18
now I would divide that by -2 to get the value for x
so no we have x = 9
now you just have to substitute that into one of the equations and simplify to get y
-2 X 9 + 4y = -2
-18 + 4y = -2
4y =16
y = 4
