Answer:

The answer is B

1 pound = 16 ounce

2 pounds = 32 ounce +3 ounce = 35 ounce.

29 ounce x 0.05 = 1.45

1.45 + 1.50 = $2.95

What in slope-intercept form, can go through the line ( a, 2a) and (-5a, 6a)
Wittaler [7]

Answer:

  • y = -2/3x + 8/3a

Step-by-step explanation:

<u>Given points</u>

  • (a, 2a) and (-5a, 6a)

<u>Slope-intercept form</u>

  • y = mx + b

<u>Slope of the line is</u>

  • m = (6a - 2a)/( -5a - a) = 4a/(-6a) = - 2/3

<u>The y-intercept is:</u>

  • 2a = -2/3*a + b
  • b = 2a + 2/3a
  • b= 8/3a

<u>So the line is:</u>

  • y = -2/3x + 8/3a

Solve using square roots 3x^2+25=73
seropon [69]
Heya !

Given expression -

3 {x}^{2} + 25 = 73

Subtracting 25 both sides ,

3 {x}^{2} + 25 - 25 = 73 - 25 \\ \\ 3 {x}^{2} = 48

Dividing by 3 on both sides ,

\frac{3 {x}^{2} }{3} = \frac{48}{3} \\ \\ {x}^{2} = 16

Therefore ,
x = + \: 4 \: \: \: \: or \: \: - 4 \: \: \: \: \: \: \: Ans.

Julia is allowed to watch no more than 5 hours of television a week. So far this week, she has watched 1.5 hours. Write and solv
mojhsa [17]

Answer:

The inequality to show how many hours of television Julia can still watch this week can be given as:

⇒ x+1.5\leq 5

where x represents he number of hours of television that Julia can still watch this week

On solving for x, we get

x\leq3.5

Thus, Julia can still watch no more than 3.5 hours of television this week.

Step-by-step explanation:

Given:

Julia is allowed to watch television no more than 5 hours a week.

She has already watched 1.5 hours

To write and solve an inequality to show how many hours of television Julia can still watch this week.

Solution:

Let the number of hours of television that Julia can still watch this week be = x

Number of hours already watched = 1.5

Total number of hours of watching television this week would be given as:

⇒ x+1.5

It is given that Julia is allowed to watch no more than 5 hours of television in a week.

Thus, the inequality can be given as:

⇒ x+1.5\leq 5

Solving for x

Subtracting both sides by 1.5

x+1.5-1.5\leq 5-1.5

x\leq3.5

Thus, Julia can still watch no more than 3.5 hours of television this week.
