Answer:
Step-by-step explanation:
F=9/5C+32 should be F = (9/5)C + 32
We are given 111 degrees F and want the same temperature in degrees Celcius.
In F = (9/5)C + 32 multiply all three terms by 5:
5F = 9C + 160, which can be solved for C:
5F - 160 = 9C
Let F = 111. Then 555 - 160 = 9C, or
395 = 9C
Dividing both sides by 9, we get C = 395/9 = 43 8/9 degrees C
Answer:
<h2>-4</h2>
Step-by-step explanation:
Given the function f(x)=(x+4)², <u>the x intercept occurs at f(x) = 0,</u> substituting f(x) = 0 into the given equation to get the value of x we have;
Taking the square root of both sides
Subtracting 4 from both sides of the equation
Therefore the x intercept of the equation is -4
Answer:
Step-by-step explanation:
m) yx(y + 1) + 4x(y +1) - 5(y +1) = (y + 1) [ yx + 4x - 5 ]
n) 6p² - 3p³ = 3p² (2 - p)
0) 4x⁴ + 2x = 2x(2x³ + 1)
Answer:
300%
Step-by-step explanation:
Let p be the percent, of means multiply and is means equals
p*24 = 72
Divide each side by 24
24p/24 = 72/24
p =3
Multiply by 100 to change from decimal form to percent form
3*100
300%
