Answer:

x=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5x+4x−68=34−8x

5x+4x+ −68=34+ −8x

(5x+4x)+(−68)=−8x+34(Combine like terms)

9x+−68=−8x+34

9x−68=−8x+34

Step 2: Add 8x to both sides.

9x −68+ 8x= −8x +34 +8x

17x −68 =34

Step 3: Add 68 to both sides.

17x −68 +68= 34 +68

17x=102

Step 4: Divide both sides by 17.

17x /17= 102/17

X=6 > final answer hope i could help :)

Answer: The area of the sector formed by central angle AOB is 5/8 th of the total area of the circle.

Step-by-step explanation:

Let r be the radius of the circle having the center O,

⇒ The area of the circle = $\pi r^2$ square unit.

And, the central angle AOB = $\frac{5\pi}{4}\text{ radian}$

$=(\frac{5\pi}{4}\times \frac{180}{\pi})^{\circ}$ ( since, $\pi$ = 180° )

$=(\frac{900}{4})^{\circ}$

$=225^{\circ}$

Hence, the area of sector AOB

$=\frac{225^{\circ}}{360^{\circ}}\times \pi r^2$

$=\frac{5}{8}\times \pi r^2$ square unit.

Now,

$\frac{\text{Area of sector AOB}}{\text{Area of circle}}=\frac{\frac{5}{8}\times \pi r^2}{\pi r^2}$

$=\frac{5}{8}$

⇒ Area of sector AOB = 5/8 × Area of the circle.

Hence, the area of the sector formed by central angle AOB is 5/8 th of the total area of the circle.

Pauline withdrew $7.50 from her savings account every day for 3 days. Which expression is the best choice to help her determine

artcher [175]

Answer:

$\$(-7.50)(3\ days)= - 22.50$

Step-by-step explanation:

Given: Pauline withdrew $7.50 each day from her saving account.

She withdrew money for 3 days.

As Pauline is withdrawing the money, therefore the amount will be in negative

Now finding the expression for total amount of money withdrew.

Total money withdrew = $(Money\ withdrew\ each\ day)\times (number\ of\ day)$

∴ Total money withdrew = $\$ -7.50\times 3\ days= - 22.50$

Hence, the expression to determine the total amount of money she withdrew is $(-7.50)(3)= -22.5$ and Total money she withdrew is -$22.5

attashe74 [19]

The answer is $\frac{2}{7}$ .

Multiple numerators by nums, and denoms by denoms.

$\\\frac{-3}{7}$ · $\frac{-2}{3}$ = $\frac{6}{21}$

$\frac{6}{21}$ simplified is $\frac{2}{7}$

Hope this helped and branluest would be appreciated
