So for this you just want to divide 4/5 by 9/10 because it is the opposite of the equation.

9/10 / 4/5

To divide fractions, you just multiply and reverse the second fraction.

For example:

9/10 * 5/4

Now you can just normally multiply.

45/40

Or, simplified,

9/8

(Or 1 1/8)

Anni [7]

Hello,

1)
$a_{1}=7$
$a_{2}=7*3$
$a_{3}=7*3^2$

$a_{n}=7*3^{n-1}$

$s=a_{1}+a_{2}+a_{3}+a_{4}+a_{5}=7*(1+3^1+3^2+3^3+3^4)$
$=7*\frac{3^{5}-1}{3-1}$
$=7*242/2=847$

$b_{8}=6*8^{8-1}=12582912$

Solve: 2x2-x = 21 {-7/2,3} {-3, 7/2}

Sergio039 [100]

Answer:

The answer is (-3,7/2)

Step-by-step explanation:

$2 {x}^{2} - x - 21 = 0 \\ (2x - 7)(x + 3) = 0 \\ 2x - 7 = 0 \: \: \: or \: \: x + 3 = 0 \\ x = \frac{7}{2} \: \: and \: x = - 3$

How many solutions exist for the system of equations graphed below?

Zinaida [17]

Answer:

one

Step-by-step explanation:

When a system of equations is graphed, the solution is the coordinate that is plotted at the intersection of the two lines.

If the two lines cross once, there is only one solution.

If the two lines are on top of each other then there are infinitely many solutions.

If the two lines are parallel ( and never touch ) then there are no solutions

By looking at the graph we notice the two lines intersect once. So we can conclude that there is only one solution.
