9/10 times a number plus 6 is 51. I need help

Mathematics
1 answer:
Norma-Jean [14]3 years ago
6 0
9/10 is .9
51 subtracted by 6 is 45
45 multiplied by .9 is 50

.9 multiplied by 50 is 45
45 plus 6 is 51

So you missing number would be 50.

Hope this helps!

If you know the number of yards for a measurement, you can change that measure to meters by multiplying the number of yards by 0
guajiro [1.7K]
Question 1)

Let "y" denotes the number of yards and "m" denotes the number of meters. According to the give statement, measurement in yards can be changed to measurement in meters by multiplying the measure in yards by 0.9144.

So,

Measure in Meter = 0.9144 x Measure in Yards
m = 0.9144y

Question 2)

We are to convert 7200 yards into meters. Using the values in above equation we can write:

m = 0.9144 x 7200
m = 6583.68 meters

This means 7200 yards are equivalent to 6583.68 meters..

Question 3)

We are to convert 2500 meters to yards.
Using the value in above equation, we get:

2500=0.9144y
⇒
y = 2500/0.9144
y = 2734.03 yards

So this means 2500 meters are equivalent to 2734.03 yards.

-6/7,-3/7,0,3/7 .... create a formula that explains the arithmetic sequence
LenKa [72]

The formula that explain the arithmetic sequence is a_{n}=\frac{3}{7}n-\frac{9}{7}

Step-by-step explanation:

The formula of the nth term in an arithmetic sequence is

a_{n}=a+(n-1)d , where

  • a is the first term
  • d is the common difference between the consecutive terms

∵ \frac{-6}{7} , \frac{-3}{7} , 0 , \frac{3}{7} are some terms of an arithmetic sequence

∵ The difference between two consecutive terms = \frac{-3}{7} - \frac{-6}{7}

∴ The difference between two consecutive terms = \frac{-3}{7} + \frac{6}{7} = \frac{3}{7}

∴ The common difference = \frac{3}{7}

∴ d = \frac{3}{7}

∵ The first term is \frac{-6}{7}

∴ a = \frac{-6}{7}

- Substitute a and d in the formula above

∴ a_{n}=\frac{-6}{7}+(n-1)\frac{3}{7}

- Simplify the right hand side

∴ a_{n}=\frac{-6}{7}+\frac{3}{7}n-\frac{3}{7}

- Add like terms

∴ a_{n}=\frac{3}{7}n-\frac{9}{7}

The formula that explain the arithmetic sequence is a_{n}=\frac{3}{7}n-\frac{9}{7}
