Answer:

Step-by-step explanation:

Lets write an equation for this :)

So, the sum of -3 times a number and 0.3

This would be : -3x +0.3

Is at most, 6.3

so, it is equal to, or less than 6.3

-3x +0.3 < 6.3

Now lets solve!

x> -2

Option 1 : x=2
Option 2 : x=-7
Option 3 : y=2
Option 4 : y=-7

Answers

Answer:

Option 1

Step-by-step explanation:

First we need to analyse the question to figure out what we need to do. The question is saying that a line is parallel to the y-axis. We know that the y-axis goes up and down, meaning that our line should be pointing up and down crossing the point (2,-7). In order to find where the line is placed, we would have to look at the x-axis to figure out where it is. Using the info provided we could see that the line has to pass (2,-7), and the x for that point is 2. Using all the info we have concluded we know that the equation of the line is x=2.

help! Solve for the value of k

Answers

Answer:

k = 42

Step-by-step explanation:

These are complementary angles so they add to 90°

43 = k + 1

k = 42

K will be equal to the number 42
K=42

The triangle-shaped entrance to the cavern is 2 1/2 feet tall and 4 feet wide. What is the area of the entrance?

Answers

Answer:

5 feet²

Step-by-step explanation:

The area of entrance = area of triangle

Height, h = 2 1/2 feets

Width, w = 4 feets

The Area of a triangle is given as :

1/2 * base * height

Base = width = 4 feets

Area of entrance = 0.5 * 4 * 2.5

Area of entrance = 5 feet²

Hence, the area of the entrance is 5 feet square.

Para encher 2/5 de uma piscina são necessários 60.000 litros de água. Qual é a capacidade dessa piscina?

Answers

Answer:

A capacidade dessa piscina é de 150.000 litros de água.

Step-by-step explanation:

A capacidade da piscina é de x.

5 Select the correct text in the passage. Which sentence best gets across the author's message in the story? A True Victory Kelso and his best friend, Adiel, had spent weeks building their go-cart for the annual Wolf Club go-cart race. Then, at the last minute, another team's go-cart broke down. Adiel and Kelso decided to let that team use their go-cart. But now they were regretting their decision. It was painful watching the race from the sidelines. When the first cart crossed the line, Adiel and Kelso couldn't helping wydering how it would have felt If they had won. Within seconds, other carts raced by. Instead of feeling glum, Kelso began to laugh. He delighted in the breeze that blew through his hair as the go-karts rushed past. Adiel noticed a genuine smile spread wide across Kelso's face. Adiel realized that this sense of happiness was also surging throughout his body, even though he had not raced. "You did a really nice thing today," whispered a nearby Wolf Club leader. "Thanks," said Adlel. "I guess I won't ever know if I could've won the race." "Well winning isn't one of the Wolf Club mottos," said the leader. "But we do believe that we should promise to do our best and do something good for somebody every day. I'd say you proved yourself today as one of the worthiest people here to be called a Wolf Cub." Adiel's mother soon appeared. "And I'm more proud of you now than I ever could have been if you had come in first," she said. Reset Next n. All rights reserved.
