8x + 15 = 7 so 8x = 7 - 15: x = -1
The real answer is n-7
The sum of fifteen times a number and eight.
Eleven
twice the difference of three times a number and eight
X = number 48 - X = 4X - 7
3x-8>15
Eight-hundred and thirteen times seven equals fifteen thousand, six hundred and ninety-one.
The real answer is n-7
The sum of fifteen times a number and eight.
Include the result of of the multiplication to produce the sentence, "Seven times eight equals fifty six."
We'll use "n" to represent "number." First, "eight times a number" means the number is multiplied by eight. 8n Then, seven is added to 8n. 8n + 7 Also, you can display it like this if it helps: (8 x n) + 7
I don't know if you want this translated or solved. x^2+15=8x

N = the number It's [ 7N + (N+8) ]
To calculate eight tenths times fifteen twelve, first convert the fractions: eight tenths is ( \frac{8}{10} ) or ( \frac{4}{5} ), and fifteen twelve is ( \frac{15}{12} ). Multiply the two fractions: [ \frac{4}{5} \times \frac{15}{12} = \frac{4 \times 15}{5 \times 12} = \frac{60}{60} = 1. ] Thus, eight tenths times fifteen twelve equals 1.
Yes; fifteen times seven is one hundred and five.
Let the number be x and so if 8x +1 = 7x then x = -1
