Answer:
The number is 10.
Step-by-step explanation:
Given that:
Four times a number plus five times the number is the same as ten more than eight times the number.
Let,
x represent the number.
According to given statement,
4 times the number + 5 times the number = 10 + eight times the number
4x+5x=10+8x
Solving the equation,
9x=10+8x
Subtracting 8x from both sides
9x-8x=10+8x-8x
x=10
Hence,
The number is 10.
Answer:
Step-by-step explanation:
A rectangle had a length of 2x-7 and a width of 3x+8y
Perimeter P = 2(l + w)
P = 2(2x - 7 + 3x + 8y)
P = 2(5x + 8y - 7)
P= 10x + 16y - 14
