The numerator of a fraction is 3 less then the denominator. If 1 is added to the numerator, the value of the fraction becomes 3/

andrew11 [14]

The fraction is $\frac{5}{8}$

Step-by-step explanation:

Let,

The denominator of fraction = x

Numerator of fraction = x-3

Fraction = $\frac{x-3}{x}$

According to given statement;

1 is added to the numerator, the value of the fraction becomes 3/4.

$\frac{x-3+1}{x}=\frac{3}{4}\\\\\frac{x-2}{x}=\frac{3}{4}$

Using cross multiplication

$4(x-2)=3*x\\4x-8=3x\\4x-3x=8\\x=8$

Fraction = $\frac{x-3}{x}=\frac{8-3}{8}=\frac{5}{8}$

Estimate the slope of the tangent line of the function y(t)=\sqrt{(3t+1} at the point t=2.

Korvikt [17]

Answer: 0.567

Step-by-step explanation:

$y(t)=\sqrt{3t+1} \\\\y'(t)=\dfrac{3}{2\sqrt{3t+1} } \\\\y'(2)=\dfrac{3}{2\sqrt{3*2+1} } =\dfrac{3\sqrt{7} }{14} =0,56694670951384084082177480435127\approx{0.567}$

Ann, Chang, and Kareem sent a total of

Gnoma [55]

It is given in the question that

Ann, Chang, and Kareem sent a total of 89 text messages over their cell phones during the weekend. Ann sent 9 fewer messages than Chang. Kareem sent 3 times as many messages as Ann.

Let number of messages Chang sent be x. And Ann sent 9 fewer than Chang, so Ann sent (x-9) messages. And Kareem sent 3 times as many messages as Ann, so Kareem sent 3(x-9) messages.

And the total messages are 89. That is

$x+x-9+3(x-9)=89$
