Answer:
An expression equivalent to 5 (x + 10) is <em>5x + 50.</em>
Let's call the two numbers x and y. We can write a system of equations to describe the situation:
5x = 8y
x - y = 150
Let's solve the first equation for x:
x = 8y/5
Now we can use substitution to solve the system by plugging 8y/5 in for x in the second equation:
(8y/5) - y = 150
Simplify:
3y/5 = 150
3y = 750
y = 250
If y = 250, then x is:
x = 8(250)/5 = 400
The answer is 250 and 400.
Answer:
16/5 or 3 1/5
Step-by-step explanation:
Your equation would be 4/5*4 which equals 16/5
Answer:
1=51°
2=18°
3=123°
4=39°
Step-by-step explanation:
the correct option is answer choice D, because there are multiple 2's in the x column with different f(x) values.
