Answer: 1,360
Step-by-step explanation:
20 * 20 = 400
20 * 12 = 240
240 * 4 = 960
960 + 400 = 1,360
1500*16=24,000
16*2=32

Answer:
84 and 8
Step-by-step explanation:
the first number will be x and the second number y.
x = 11y - 4
x + y = 92
replace x in the second equation with 11y - 4:
11y - 4 + y = 92
add 4 to each side: 11y + y = 96
simplify: 12y = 96
divide each side by 12: y = 8
now replace y in the second equation with 8:
x + 8 = 92
subtract 8 from each side: x = 84
