Answer:

x=11

Step-by-step explanation:

If F is the midpoint for EG, then the length of EF and FG are same

F is a midpoint for EG , so EF = FG4

$EF = 6x - 4, FG = 5x + 7$

LEts replace EF and FG

$EF = FG$

$6x-4= 5x+7$ , solve for x

Subtract 5x on both sides

$6x-5x-4= 5x-5x+7$

$x-4=7$

Add 4 on both sides

x=11

The value of x= 11

I hope this helps you

EF=FG

6x-4=5x+7

x=11

The perimeter of the cover of a math textbook is 34 inches. if the width of the cover is 7 inches, what is the length of the cov

Sauron [17]

The length would be 10 inches.
to find perimeter, you add length+length+width+width.
since both widths and both lengths have to be the same, u add the width 2 times or 7+7=14.
next u subtract 14 from 34 or 34-14=20.
since u still have 2 lengths that are equal, u divide 20 by 2 or 20/2=10

hope this helps! :)

7 out of 28 is what percent?

jeka57 [31]

Here's what I did and I checked it So it is correct!!

$\frac{7}{28} = \frac{1}{4}$

$\frac{1}{4} = 0.25$

25% is your answer.

$28 \times 25\% = 7$

Andrews [41]

Answer:

$f(x) = \frac{24}{25} * \frac{5}{6}^x$

Step-by-step explanation:

Given

$(x_1,y_1) = (2,\frac{2}{3})$

$(x_2,y_2) = (3,\frac{5}{9})$

Required

Write the equation of the function $f(x) = ab^x$

Express the function as:

$y = ab^x$

In: $(x_1,y_1) = (2,\frac{2}{3})$

$y = ab^x$

$\frac{2}{3} = a * b^2$ --- (1)

In $(x_2,y_2) = (3,\frac{5}{9})$

$y = ab^x$

$\frac{5}{9} = a * b^3$ --- (2)

Divide (2) by (1)

$\frac{5}{9}/\frac{2}{3} = \frac{a*b^3}{a*b^2}$

$\frac{5}{9}/\frac{2}{3} = b$

$\frac{5}{9}*\frac{3}{2} = b$

$\frac{5}{3}*\frac{1}{2} = b$

$\frac{5}{6} = b$

$b = \frac{5}{6}$

Substitute 5/6 for b in (1)

$\frac{2}{3} = a * b^2$

$\frac{2}{3} = a * \frac{5}{6}^2$

$\frac{2}{3} = a * \frac{25}{36}$

$a = \frac{2}{3} * \frac{36}{25}$

$a = \frac{2}{1} * \frac{12}{25}$

$a = \frac{24}{25}$

The function: $f(x) = ab^x$

$f(x) = \frac{24}{25} * \frac{5}{6}^x$
