Marizza181 [45]

Answer:

Step-by-step explanation:

Since Greg has calculated that his least or minimum speed should.be 50 miles per hour ;

Then the line starts at 50 with the starting point shaded due to the atleast notation.

Then atleast means that, Gregg may need to travel at a higher speed than 50, so the direction of the arrow moves to the right of the number line depicting a possible increase in Gregg's speed.

Therefore, the number line which best conveys Gregg's situation is B.

* WILL GIVE BRIANLIEST 5 QS PLZZ HELP MEH ;D*(07.01)What is the solution to the equation 5x = 40?

Maru [420]

Hello there! :)

Answer:

1. B. 8. and x=8

*The answer must have a positive sign.*

2. D. Infinitely many.

3. D. -1 and y=-1

*The answer must have a negative sign.*

4. C. He didn't add 13 to 26.

5. B. 4 and y=4

*The answer must have a positive sign.*

Step-by-step explanation:

1. First, you divide by 5 from both sides of an equation.

$\frac{5x}{5}=\frac{40}{5}$

Then, simplify.

$40/5=8$

Answer: → $\boxed{x=8}$

_______________________________________________

2. 4x=4x both sides are equal and it's true.

Answer: $\boxed{D.}$

________________________________________________

3. First, switch sides of an equation.

$y+9=8$

Then, you subtract by 9 from both sides of an equation.

$y+9-9=8-9$

Simplify and solve.

$8-9=-1$

Answer: → $\boxed{y=-1}$

________________________________________________________

4. First, add by 13 from both sides of an equation.

$x-13+13=26+13$

Then simplify and solve.

$26+13=39$

Answer: $\boxed{x=39}$ and $\boxed{C.}$

_______________________________________________________

5. First, subtract by 9 from both sides of an equation.

$y+9-9=13-9$

Then simplify and solve.

$13-9=4$

Answer: $\boxed{y=4}$
