What is the solution to the inequality 7<=-3x-4

Answers

Answer:

The nearest option is -3 (negative 3)

So, Option B is correct.

Step-by-step explanation:

We need to solve the inequality [tex]7 \leq -3x-4[/tex]

Solving:

Step 1: Switching sides of inequality and reversing the inequality

[tex]-3x-4\geq 7[/tex]

Step 2: Adding 4 on both sides

[tex]-3x-4+4\geq 7+4\\-3x\geq 11[/tex]

Step 3: Dividing both sides by -3 and reversing the inequality

[tex]\frac{-3x}{-3}\leq \frac{11}{-3} \\x\leq -3.6\\[/tex]

The nearest option is -3 (negative 3)

So, Option B is correct.

Jasmin can walk 1/4 mile every 1/5 hour. At this rate, how far can Jasmin
walk in one hour?

Answers

Answer:

hope this helps :)

Step-by-step explanation:

Since we know how far she can walk in 1/5 (one fifth) of an hour, if we multiply this distance by 5, we will find out how far she can walking in 5/5 (five fifths) of an hour, or to be clear: in one hour.

So, 5 x 1/4 miles = 5/4 or 1.25 miles per hour

Use substitution to solve the system.

X= 2y-5
4x+3y=-9

Answers

Step-by-step explanation:

x=2y-5 - equation 1

4x+3y=-9 -equation 2

Replace equation 1 in equation 2

4(2y-5)+3y=-9

8y-20+3y=-9

11y=-9+20

11y=11

y=11/11

y=1

If y=1, therefore x=2(1)-5=-3

x=-3,y=1

A class has 30 students. 18 are boys. what id the ratio of boys to girls? (you must simplify)

Answers

Answer:

number of students =30

boys =18

girls =30-18=12

therefore,the ratio of boys :girls

=18:12

then simpilyfing, =3:2

The ratio of the number of boys to girls in the class is 3 : 2

Total number of students = 30

Number of boys = 18

Nunber of girls = 30 - 18 = 12

The ratio of boys to girls :

Number of boys : Number of girls 18 : 12

Simplify to lowest term :

Divide both sides by 63 : 2

Therefore, the ratio of boys to girls is 3 : 2

Scholars estimate that the sword was first introduced to Japan in 200 B.C. The sword went through many transitions from its original form, and in the middle of the 11th century, it emerged as an elegant weapon with a curved and slightly arched blade.(2) The years passed, and kendo began to take on a new form. In the late 1800s, bamboo swords called shinai took the place of iron swords, and warriors began to wear protective armor to protect themselves from injury. When the samurai class was abolished in 1868, the practice of kendo began to decline. A few years later, the practice was revived and was used to train police officers.(3) By the end of the 12th century, unrest in the government led to the development of a warrior class. The samurai elevated sword making into a revered art form. From the 14th to the 16th centuries, prestigious sword fighting schools developed to help warriors hone their skills.(4) The Dai Nippon Butoku Kai, a martial arts organization, was established in 1895. More than a decade later, kendo was added to the physical education curriculum in Japanese middle schools. Kendo again suffered a decline after World War II. It wasn't until 1952 that a new form of kendo called "Shinai Kyogi" was created and introduced into public schools. Today, kendo is growing in popularity around the world.39What is the best order for paragraphs 2, 3, and 4?A. 3, 2, 4B. 2, 4, 3C. no changeD. 4, 3, 2Plz help , i Ava is driving home from college this winter holiday.
