Answer:

The last one   5x-3y=15   This is the same as  y= (5/3)x -5

Step-by-step explanation:

5x-3y=15

Move 5x to the right (becoming negative)

-3y = -5x +15

Divide everything by - 3

y= (5/3)x -5

y intersect= -5   ( line crosses y coordinate at -5)

Slope = 5/3      From -5  you start counting  (5 up,3 right,5 up,3 right....  OR    5 down,3 left,5 down,3 left........)

Answer:

About About 21 km/h

Step-by-step explanation: If they travel 63 km in 3 hours then all it is is just 63 divided by 3 or 63/3.

The average speed for the cycle will be 21 km per hour.

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.

The average speed is defined as the ratio of the total distance traveled and the total time taken by the object.

Given that A student cycles a distance of 63 km in less than 3 hours. The average speed is calculated as:-

Average speed = Distance / time

Average  speed  = 63 / 3

Average  speed = 21 km / hr

Answer:

P(x < 149.6) = 0.11821

Step-by-step explanation:

We start by calculating the z-score of the parameter given

Mathematically,

z-score = (x-mean)/SD/√n

z-score = (149.6-152.8)/26.2/√94

z-score = -3.2/2.70

z-score = -1.18

So the probability we want to calculate is;

P( x < -1.18)

we can use the standard normal distribution table to get this

From the standard normal distribution table, this value is 0.11821

Step-by-step explanation:

Answer: Distributive Property

The term "distribution" is also used in place of "distributive"

This property says

x*(y+z) = x*y + x*z

We multiply the outer term x with each inner term (y and z). Then we add the results.

In this case,

x = 5

y = a

z = 3b

So,

5(a+3b) = 5*a + 5*3b = 5a+15b

Answer:

the answer to your question is y = -30

Answer:

-30

-Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1/2y+5=-10

Step 2: Subtract 5 from both sides.

1/2y+5-5=-10-5

1/2y+-15

Step 3: Multiply both sides by 2.

2*(1/2y)=(2)*(-15)

y=-30

          ×       21  

                332

             664

Answer:

[tex]\frac{7}{8}[/tex]

Step-by-step explanation:

To find the total amount of flour and sugar, you have to find a common denominator for the two fractions and then add them together.

[tex]\frac{1}{2}[/tex] multiplied by 4 equals [tex]\frac{4}{8}[/tex].

Now that the fractions both have a common denominator of 8, we can add them together:

[tex]\frac{3}{8}[/tex] + [tex]\frac{4}{8}[/tex] = [tex]\frac{7}{8}[/tex]

The total amount of flour and sugar is [tex]\frac{7}{8}[/tex]

The inequality which best represents the purchase is x + y > 12.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Given that,

At an end of the year sale, Gabriela bought more than 12 bottles of hand soaps and lotions.

Let x represents the number of hand soaps she bought.

Let y represents the number of lotions she bought.

x + y is more than 12.

So the inequality is,

x + y > 12

Hence the correct inequality is x + y > 12.

Answer:

35 cm^2

Step-by-step explanation:

To find the area you need to find the width and height which we have.

Now all you need to do is to use the formula Height x Width= area

so replace height with 5 cm and width with 7 cm

5 cm x 7 cm = area

5 times 7 is 35 so the area of the parallelogram is 35 cm^2 (cm times cm is cm^2)

Hope this helps!

Step-by-step explanation:

He played 2 games because he already paid $5 to rent a pair of bowling shoes and each game cost $5. So all you have to do is add 5+3 and that would give you 8. That's not quit 11 yet so add another 3. 8+3 would equal 11.

Equation: 5+3+3=11

Answer:

if its not a perfect square(like u can't square it) then its irrational

Answer:

Step-by-step explanation:

We know that the angle of elevation is 8 degrees.

We know that the height of the opposite side of the angle is 3 feet.

We want to know the adjacent side (the side from the start of the ramp to the bottom of the opposite side)

We can do this with tangent

[tex]tan(8) = \frac{3}{adj} \\adj = \frac{3}{tan(8)} \\adj = 21.34611 feet[/tex]

The distance between the ramp and the door can be calculated using the principle of Pythagoras, Hence, the distance should be 21.34 feets

Using SOHCAHTOA :

Tanθ = Opposite / Adjacent

Tan(8°) = 3 / d

0.1405408 = 3 / d

0.1405408d = 3

Divide both sides by 0.1405408 to isolate d

0.1405408d / 0.1405408 = 3 / 0.1405408

d = 21.34 feets

Therefore, the distance of the ramp from the door should be 21.34 feets
