9 + 1/2 (7n - 26) - 8n
Expand brackets by multiplying by 1/2:
9 + 3.5n - 13 - 8n
Collect like terms:
4.5n - 4
Turn it into an equation:
4.5n - 4 = 0
Isolate 4.5n by adding 4 to both sides:
4.5n = 4
Divide both sides by 4.5 to get the value of n:
n = 8/9
Answer:
45 is 125% of 36, and 36 is 80% of 45.
Step-by-step explanation:
Answer:
So we have an original figure with a value of 50 and then a scaled version or dilation
Hence we have a scale factor of
![\frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7D%20)
To divide 54,164 by 44, we start from the first digit.
First we take the first 2 digits: i.e. 54 divided by 44, which gives 1 remainder 10.
Next, we join the next digit to the remainder and divide again by 44: i.e. 101 divided by 44, which gives 2 remainder 13.
Next, we join the next digit to the remainder and divide again by 44: i.e. 136 divided by 44, which gives 3 remainder 4.
Next, we join the next digit to the remainder and divide again by 44: i.e. 44 divided by 44, which gives 1.
We now joining all the results from our algorithm, to get that 54,164 divided by 44 is 1,231.
