what did he do wrong

Answer:

7

Step-by-step explanation:

We can solve this problem by making an equation.

Let x represent the second number

3x + 2 will be the first number because it is 2 more than triple x

This makes our equation:

3x + 2 + x = 30

Combine like terms

4x + 2 = 30

Subtract 2 from both sides

4x = 28

Divide both sides by 4

x = 7

The smaller number aka the second number is 7

Step-by-step explanation:

First, remove the 1/8 by subtracting 1/8 on both sides

-3p = -3/8

Then, isolate the variable by diving each side by -3

p = 0.125

Answer:

From the formula above, you see that your slope would be the $12.

Step-by-step explanation:

So, from this problem the base rate is the y-intercept because it is fixed. The slope of the is the additional fee because it's changing by the number of albums sold. Below is the equation that should have been created using the slope intercept formula.

220 + 12x = 644

You will need the slope intercept form, y = mx + b  

m is the slope

b is the y-intercept

Answer/Step-by-step explanation:

✔️<1 can be named in two ways using letters, with the middle letter being the letter of the vertex of the angle. Thus is can be named as:

[tex] \angle ADB [/tex] or as [tex] \angle BDA [/tex]

✔️It is unclear to name <1 as <D because <2 can equally be named as <2 since both angles share a common point or vertex D.

Answer:

Angles measuring 90°, 45°, and 45°: Can make triangle

Angles measuring 27°, 35°, and 108°: Can not make triangle

Angles measuring 82°, 41°, and 57°: Can make triangle

Sides measuring 8 cm, 12 cm, and 5 cm: Can make triangle

Sides measuring 7 in., 4 in., and 13 in: Can not make triangle

Sides measuring 43 cm, 41 cm, and 58 cm: Can make triangle

Step-by-step explanation:

For the angles to form a triangle, there sum must be equal to 180°

Angles measuring 90°, 45°, and 45°

Sum of Angles = 90° + 45° +45° = 180°

Hence, this combination can make triangle.

Angles measuring 27°, 35°, and 108°

Sum of Angles = 27° + 35° + 108° = 170° ≠ 180°

Hence, this combination can not make triangle.

Angles measuring 82°, 41°, and 57°

Sum of Angles = 82° + 41° +57° = 180°

Hence, this combination can make triangle.

For three sides to form a triangle the sum of the two sides must be greater than the length of third side.

Sides measuring 8 cm, 12 cm, and 5 cm

(8 cm + 12 cm) > 5 cm (True)

(8 cm + 5 cm) > 12 cm (True)

(12 cm + 5 cm) > 8 cm (True)

Hence, this combination can make triangle.

Sides measuring 7 in., 4 in., and 13 in

(7 in + 4 in) > 13 in (False)

Hence, this combination can not make triangle.

Sides measuring 43 cm, 41 cm, and 58 cm

(43 cm + 41 cm) > 58 cm (True)

(43 cm + 58 cm) > 41 cm (True)

(41 cm + 58 cm) > 43 cm (True)

Hence, this combination can make triangle.

Answer:

A- Angles measuring 90°, 45°, and 45°.

C- Angles measuring 82°, 41°, and 57°.

D- Sides measuring 8 cm, 12 cm, and 5 cm

F- Sides measuring 43 cm, 41 cm, and 58 cm.

Answer:

The sale price is $34

Step-by-step explanation:

If we are given the regular price P and the markdown percentage r, we follow these steps:

1) Calculate the markdown or discount amount M.

M = P*r/100

2) Subtract it from the regular price:

S = P - M

S is the sale price.

Example: The regular price is $40 and the markdown percentage is 15%. Thus:

1) M = $40*15/100 = $6

2) S = $40 - $6 = $34

The sale price is $34

Answer:

$494

Step-by-step explanation:

Given that:

Cost of golf club = $1700

Number of months taken to balance payment after down payment = 6 months

Amount paid per month = $201

The down payment made :

Cost of golf clubs - (monthly payment * number of months)

$1700 - ($201 * 6)

$1700 - $1206

= $494

Hence, the downpayment made = $494

Answer: B

Step-by-step explanation:

The lines outside the number on the left represent absolute value, meaning it doesnt matter if it is negative you just count it as positive. Since the number on the left is greater than the number on the right, the answer is B

Answer:

£30

Step-by-step explanation:

→ Model the situation in terms of x

Richard = x, Natasha = 3x and Krutika = 6x

→ Now put the values into ratio form

6x : 3x : x = 50

→ Collect the x terms

10x = 50

→ Divide both sides by 10 to isolate

x = 5

→ Substitute x = 5 into Krutika

6 × 5 = 30

Answer:

£30

Step-by-step explanation:

Let's break down the information given to help us find how much Krutika gets.

"Natasha gets three times as much as Richard" - We can express the value that Natasha gets as [tex]3r[/tex] in terms of what Richard gets.

"Krutika gets twice as much as Natasha" - We can express this as [tex]2(3r)[/tex] which equals [tex]6r[/tex].

We know that the total money is £50, so we can write the equation:

[tex]r+3r+6r=50[/tex]

[tex]10r = 50[/tex]

[tex]r=5[/tex]

∴ Richard gets £5.

Since the money Krutika gets can be expressed as [tex]6r[/tex]:

[tex]6(5) = 30[/tex]

∴ Krutika gets £30.

The equation of a line in point-slope form is  (y + 8) = 4(x - 2).

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, A line passes through the point (x₁, y₁) ⇒ (2,-8) and had a slope of 4.

We know the equation of a line in point-slope form is (y - y₁) = m(x - x₁).

∴ The equation of this line is (y + 8) = 4(x - 2).

Step-by-step explanation:

First find 28% of $19.50:

($19.50) / (100) × (28) = $5.46

Now minus the 285 from the original price:

($19.50) - ($5.46) = $14.04

The answer is $14.04

Hope it helped :)

Answer:

the answer is 341(I think)

113 = 3 • 36 + 5

(That is, 36 = 6² is the largest power of 6 that fits into 113. The next power 6³ = 216 exceeds 113.) Then

113₁₀ = 3 • 6² + 5 • 6⁰ = 305₆

Answer: Point A

Step-by-step explanation:

The temperature at midnight is;

= 5 - 15

= -10°C

Looking at the number line, one can surmise that the scale is in multiples of 5. This means that C is 10, B is -5 and A is -10.

With point A being -10°C, it represents the colder midnight temperature.

Answer:

Point A

Step-by-step explanation:

We know that the temperature dropped 15 degrees, and that it was initially of 5°C. So, by midnight, the temperature will be of -10°C (5-15=-10).

We also know that the distance between points is of 5°C. So, the point that we have to mark is point A, which represents -10°C.

Answer:  [tex]-p^2-(q+r)^2[/tex]

Work Shown:

I'm assuming your teacher wants you to factor as much as possible.

[tex]-p^2-q^2-r^2-2qr\\\\-p^2-q^2-2qr-r^2\\\\-p^2-(q^2+2qr+r^2)\\\\-p^2-(q+r)^2\\\\[/tex]

In the last step, I used the rule that [tex](a+b)^2 = a^2+2ab+b^2[/tex]

We cannot factor any further. If the first term was [tex]p^2[/tex] instead of [tex]-p^2[/tex], then we could use the difference of squares factoring rule.
