ehidna [41]2 years ago

4 0

Answer:

No solution.

Step-by-step explanation:

2x + y = 7

-2x - y = 6

From the first equation:

y = 7 - 2x

Plug this into the second equation:

-2x - (7 - 2x) = 6

-2x + 2x = 6 + 7

0 = 13

this doesn't make sense so theer is:

No solution.

USPshnik [31]

Answer: 0.4729%

Step-by-step explanation:

The formula to find the percent of a part in total amount :-

$\%=\dfrac{\text{Part}}{\text{Total}}\times100$

Given : Total amount = 1,1050.00

Part of total amount = 52.25

Now, substitute all the values in the formula , we get

$\%=\dfrac{52.25}{11050}\times100\\\\\Rightarrow\ \%=\dfrac{5225}{1105000}\times100=\dfrac{5225}{11050}=0.472850678733\approx0.4729\%$

Hence, 52.25 is <u>0.4729</u>% of 1,1050.00.
