Answer:
10
Step-by-step explanation:
For x=2, this is ...
5·2 = 10
I think it’s the third one and the last two. I’m sorry if it’s wrong
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:
B
Step-by-step explanation:
Answer:
d = 11
Step-by-step explanation:
10 - d = -34 - 5d
10 (- d + d) = -34 (- 5d + d)
10 = -34 - 4d
10 + 34 = (-34 + 34) - 4d
44 = 4d
44/4 = 4d/4
d = 11
