10. 5 x (3+7) = 50
11. ?
12. 100 - (3x6+5) - 4 gets your 73, you cannot get 63 (from my understanding, but make sure)
Answer:
if u meant 1.60 than yes but even if you didn't it's still no
ln(20) + ln(5) = 2 ln(<em>x</em>)
ln(20×5) = ln(<em>x</em> ²)
ln(100) = ln(<em>x</em> ²)
100 = <em>x</em> ²
<em>x</em> = 10
Answer:
60 and 38
Step-by-step explanation:
let the two numbers be X and Y
X + Y = 98-----------(1 )
X - Y = 22-----------(2)
using elimination method, subtracting equation (1) from equation (2)
X - X = 0
+Y -(-Y) = Y + Y = 2Y
98 -22 = 76
2Y = 76
dividing bothsides by 2
2Y/2 = 76/2
Y = 38
substitute Y = 38 into equation (1)
X + 38 = 98
X = 98-38 = 60
therefore, the two numbers are 60 and 38
D is most likely right. Basically, I would turn them into decimals and divide using a graphing calculator.
