Answer:

x/5 +1 = 21

Step-by-step explanation:

x is your variable. first step is divided by 5, so you put x/5. then it says add 1 so simply add it on to the equation x/5 + 1. the entire equation equals to 21 so you put the equal sign after x/5 +1 =21

Answer:

P' (-7, -4) , Q' (7, -8) , R' (-8, 4)

Step-by-step explanation:

Reflection in the y -axis:

The rule for a reflection over the y-axis is (x, y) → (−x, y).

P (7, -4) → P' (-7, -4)

Q (-7, -8) → Q' (7, -8)

R (8, 4) → R' (-8, 4)

The steps your teacher gave you are on the right track, but not quite 100% correct.

The first line has us find the area of the entire patio. That area being 110.25 square feet.

The next step is to find the area of each stone. That would be 1.5 x 1.5 = 2.25 square feet.

Therefore, the patio is made up of 110.25 ÷ 2.25 = 49 tiles

When arranged into a square, we'll have a 7 by 7 square set of stone tiles. Notice how 7 x 7 = 49.

Answer:

150°

Step-by-step explanation:

They are complimentary angles, 30° is compliment x°

x° = 180° - 30° = 150°

Answer:

x = 30°

Step-by-step explanation:

We know that the angles of the corresponding interior angles are equal.

Therefore,

Answer:

a+b=-34

Step-by-step explanation:

a and b represent the two unknown numbers, which we know to sum to -34

Answer:

x-18°+24°=180°[co interior angle]

x+6°=180°

x=180°-6°

x=174°

The question is an illustration of simple interest.

The equation that relates Barry's savings after t years is; [tex]f(t)=1300 + 28.6t[/tex]

The given parameters are:

[tex]P = 1300[/tex] --- the amount deposited

[tex]r = 2.2\%[/tex] --- annual interest

So, the interest is calculated using:

[tex]I = PRT[/tex]

This gives

[tex]I = 1300 \times 2.2\% \times t[/tex]

[tex]I = 28.6 \times t[/tex]

[tex]I = 28.6t[/tex]

So, the equation that relates Barry's savings after t years is;

[tex]f(t)=P + I[/tex] --- i.e. the amount deposited plus the interest

This gives

[tex]f(t)=1300 + 28.6t[/tex]

Hence, the required equation is: [tex]f(t)=1300 + 28.6t[/tex]

Step-by-step explanation:

Distance is the product of speed and time. Hence, the distance covered by Leika is 12k - 72 miles.

Given that :

Recall :

Distance covered by Leila can be calculated thus :

Distance = 12 × (k - 6)

Distance = 12k - 72

Therefore, the distance covered by Leila is 12k - 72 miles.

For the time k less than 6 hours, the distance that Leila travel is less than 72 miles.

The given parameters;

The maximum distance that Leila can travel in a time less than 6 hours is calculated as follows;

Distance < speed x time

Distance < 12 mph x 6 hours

Distance < 72 miles

Thus, for the time k less than 6 hours, the distance that Leila travel is less than 72 miles.

Answer:

What is the length of an arc cut off?

If θ (in radians) is a central angle in a circle with radius r, then the length of the arc cut off by θ is given by s = r θ (θ is in radians).

Step-by-step explanation:

Length of an Arc = θ × r, where θ is in radian.

Length of an Arc = θ × (π/180) × r, where θ is in degree.

Answer:

-31/4

Step-by-step explanation:

[tex]\frac{1}{2} ^{2}[/tex] is actually just (1/2)(1/2) and that equals 1/4

2 - (2/3) you can simplify to (6/3) - (2/3). that equals 4/3

now put it together!

(1/4) - 6(4/3)

(1/4) - (24/3) --------> (which simplifies to 8)

1/4 - 8 ----> (now you have to simplify this to match 1/4 denominator)

(1/4) - (32/4)

-31/4

Answer:

division property of equality

Step-by-step explanation:

First in order to solve we must learn the properties of equality:

Addition property of Inequality:

If a > b , then a + c > b + c

substraction property of inequality

If a > b , then a - c > b - c

Multiplication property of inequality

If a > b , then a * c > b * c (if c > 0)

Division property of inequality

If a > b , then a / c > b / c (if c > 0)

Step 3: 2x>10

Step 4: x>5

When we divide by 2x/2 and 10/2 we get x>5 so we must use the division property of equality

Answer:

The equation which relates the height of the flower pot based on the number of pots is 4a + 16

Creating a system of linear equations based on the information given :

4a + b = 32 - - - - - (1)

2a + b = 24 - - - - - (2)

From (2)

2a + b = 24

Make b the subject ;

b = 24 - 2a - - - - (3)

Put b = 24 - 2a in (1)

4a + 24 - 2a = 32

4a - 2a + 24 = 32

2a = 32 - 24

2a = 8

a = 8/2

a = 4

From (3) :

b = 24 - 2(4)

b = 24 - 8

b = 16

The equation which relates the height of a flower pot is 4a + 16
