To do this put into the calculator 30 divided by 35, which will get you about 0.8571 and for percentage you multiply it by hundred so that will get you about 85.71% and then round it to the nearest percentage, and since 7 is greater then 5 you would round up so your rounded percentage would be 86%

I think it’s m^5 because if you multiply m^7 times m^2 you get m^14 and if you combine it with m^9 you subtract 9 and get m^5

Ivan

The answer is unreasonable because the value of x is between 2 and 3.The error is : she did not introducing logs in solving the equation.

Step-by-step explanation:

The question is 7^x=95

Here answers is unreasonable because, she can test with powers of seven like;

7²=49

7³=343

So this means the value of x lies between 2 and 3, so here answer 11.71 is unreasonable

b) In this case, to solve the equation, introduce logs both sides

7^x=95

log7^x=log95\\\\\\xlog7=log95\\\\\\x=\frac{log95}{log7} \\\\\\x=2.340

the sum of the digits of a two-digit number is 14. the first digit is 4 less than twice the second digit. what is the number
Blizzard [7]

Answer:

86

Step-by-step explanation:

t = ten's digit    u= one's digit

t + u = 14            t = 2u - 4

In the first equation substitute for t 2u - 4 that we find in the second equation above.

t + u = 14

2u - 4 + u = 14  Combine the u's

3u - 4 = 14  Now add 14 to both sides

3u = 18  Divide both sides by 3

u = 6.  We found the unit's digit, now we will find the ten's unit by plugging in 6 for u in the first equation above.

t + u = 14

t + 6 = 14  Subtract 6 from both sides

t = 8

So, your answer is 86.
