Svet_ta [12734]

Answer:

No solution

Step-by-step explanation:

Given: 12x+7 and  5x-8\geq 40

Handle each inequality separately.

12x+7              Utilizing the subtraction property of inequalities

12x

12x

x

x

and

5x-8\geq 40               Utilizing the addition property of inequalities

5x\geq 40+8

5x\geq 48

x\geq \dfrac{48}{5}

Thus, the solution to the combined inequality is the overlap of both solutions.

Molly and Arthur are taking their daughter Ginny on a roller coaster ride. For safety, they need to find their total weight befo
Zina [12379]

Answer:

This phrasing is unusual, but let's attempt to tackle it:

M stands for Molly's weight

A represents Arthur's weight

G signifies Ginny's weight.

We can express the total weight as:

(M + A) + G

or alternatively as:

A + (G + M)

the first configuration illustrates Molly and Arthur's weights combined (hence their weight is presented as a single value), followed by Ginny's weight calculated separately.

The second configuration indicates Arthur's weight on its own, while Ginny and Molly's weights are combined (which is why their total weight appears as a single value)

Sandy takes a day off once every 4 days, and Morgan takes a day off once every 10 days. Today, both of them have taken the day o
Zina [12379]
Assuming that the departure day for both is day 0, Sandy's next day off occurs on day 4, while Morgan's falls on day 10. Sandy's days off will be on days 4, 8, 12, 16, and 20. Meanwhile, Morgan's days off will be on days 10, 20, 30, 40, and 50. Thus, both of them will share a day off on day 20, meaning they will next have a joint day off in 20 days.

The mayor of a town receives 75% of the votes in a town election. If 680 people voted, how many votes did the mayor receive? 360
zzz [12365]
First, you need to convert everything to a single unit. For this example, I'll use fractions.
75% = 3/4

680/1 * 3/4

Cross Multiply

2040/4

Reduce

510

The mayor garnered 510 votes.

Sam bought brushes for $8, a palette for $5, and oil paints for $15. He paid $29.82 in all. What sales-tax rate did Sam pay?
PIT_PIT [12445]
The total cost before tax was calculated as $8 + $5 + $15 = $28
He spent (including tax) $29.82, thus
$29.82 - $28 = $1.82 (sales tax)

To determine the sales tax rate, we can use the following calculation:

$1.82 / $28 * 100 = 0.065 * 100% = 6.5%

To verify:

$28 * 6.5 / 100 = $1.82

Adding that to $28 gives a total of $29.82 that he paid altogether.

Therefore, the sales tax rate is 6.5%
