Answer:
Singer A generated $ 210 million in ticket sales and Singer B generated $ 184 million
Step-by-step explanation:
Let
x = number of millions of dollars generated by Singer A
y = number of millions of dollars generated by Singer B
Together, they generated $394 million
x + y = 394
Singer B took in $26 million less than Singer A
y = x - 26
We got a system of equations with two unknowns
x + y = 394
x - y = 26
We add them together
2x = 420
x = 210
y = (210) - 26 = 184
This means that
Singer A generated $ 210 million in ticket sales and Singer B generated $
184 million
B)
E = mc^2
E = 7 * 5^2
E = 7 * 25
E = 175
c)
b = sqrt (c/d)
b = sqrt (100/4)
b = sqrt (25)
b = 5
