Answer: 22.5
Step-by-step explanation:
Multiply 3/4 by 30 to get the answer.
The answer is 1/27
To raise a fraction to a power, raise the numerator and denominator to that power
1 raised to any power equals 1
The answer is $81.25. Because you take the equation x times .8 = 65 and solve for x.
Answer:
Step-by-step explanation:
A = (2)(3.14)(2)(4) + (2)(3.14)(2^2)
A = 75.36 in
Let the x represent the unknown number.
"2 times a number" is 2x
"The sum of 2 times a number and 11" is 2x + 11
"The sum of 2 times a number and 11 is -7" is 2x + 11 = -7
Now we solve the equation for x to find the unknown number.
2x + 11 = -7
Subtract 11 from both sides.
2x = -18
Divide both sides by 2.
x = -9
Answer: The number is -9.
Check: 2 times -9 = -18
-18 + 11 = -7
The answer is correct.
