If you multiply a number by 3 and then add 40, the result is the same as if you add 17 to the number and then multiply by 2. What is the result if you subtract 9 from the number and then multiply by 4? .

Answer:

27.5

Step-by-step explanation:

Radius is half the diameter of a circle so just divide 55 by 2.

Answer:

27.5

Step-by-step explanation:

55/2=27.5

Answer:

0.78125g

Step-by-step explanation:

Since there are 35 days in 5 weeks, 7 half-lives of Bismuth-210 will take place. To solve for that, you can divide 100g by 2, 7 times or simply: [tex]\frac{100}{2^{7}}[/tex]

[tex]\frac{100}{2} =50\\\frac{50}{2} =25\\\frac{25}{2} =12.5\\\frac{12.5}{2} =6.25\\\frac{6.25}{2} =3.125\\\frac{3.125}{2} =1.5625\\\frac{1.5625}{2} =0.78125[/tex]

Answer:

4y = 2

Step-by-step explanation:

9y + 5 = 7 + 3y + 2y

9y-2y-3y=7-5

4y=2

Answer:

4y=2 is your answer

Step-by-step explanation:

9y + 5 = 7 + 3y + 2y

9y+5=7+5y

maintaining common form in each side

9y-5y=7-5

Answer:

For Example:  Evaluate a2b for a = –2, b = 3, c = –4, and d = 4.

Step-by-step explanation:

To find my answer, I just plug in the given values, being careful to use parentheses, particularly around the "minus" signs. Especially when I'm just starting out, drawing the parentheses first may be helpful:

a2 b

(    )2 (  )

(–2)2 (3)

(4)(3)

12

Note how using parentheses helped me keep track of the "minus" sign on the value of a. This was important, because I might otherwise have squared only the 2, ending up with –4, which would have been wrong.

By the way, it turned out that we didn't need the values for the variables c and d. When you're given a big set of expressions to evaluate, you should expect that there will often be one or another of the variables that won't be included in any particular exercise in the set.

Evaluate a – cd for a = –2, b = 3, c = –4, and d = 4.

In this exercise, they've given me extra information. There is no b in the expression they want me to evaluate, so I can ignore this value in my working:

(–2) – (–4)(4)

–2 – (–16)

–2 + 16

16 – 2

Given:

A dealer made a profit of 25% by selling a car for a 1000 naira.

To find:

The cost price of the car​.

Solution:

Let x be the cost price of the car.

A dealer made a profit of 25% by selling a car. So, the selling price of the car is

[tex]S.P.=x+\dfrac{25}{100}x[/tex]

[tex]S.P.=x+0.25x[/tex]

[tex]S.P.=1.25x[/tex]

It is given that the selling price of the car is 1000. So,

[tex]1.25x=1000[/tex]

[tex]x=\dfrac{1000}{1.25}[/tex]

[tex]x=800[/tex]

Therefore, the cost price of the car​ is 800.

Answer:

Step-by-step explanation:

Where a transversal crosses parallel lines, the angles outside the parallel lines are called exterior angles. When they are on opposite sides of the transversal, they are alternate exterior angles.

Alternate exterior angles are congruent.

The share a side (the transversal, but not a vertex. So they are non-adjacent.

_____

Additional comment

In this geometry, corresponding angles are congruent. Of course, vertical angles are always congruent. Each alternate exterior angle is a vertical angle with one that is corresponding to the other alternate exterior angle.

Answer:

34 degrees

Step-by-step explanation:

A triangle equals 180 degrees

180 - 90 = 90

90 - 56 = 34

Therefore it's 34 degrees

Answer:

The correct answer is: Find half the difference of 14 and 6, multiply by 6, then add 4.

Step-by-step explanation:

By Hierarchy Rules of Operators, we must follow these steps:

(i) Subtract 6 from 14.

[tex]\frac{1}{2}\times 8\times 6 + 4[/tex]

(ii) Multiply the result in (i) by [tex]\frac{1}{2}[/tex] and 6.

[tex]24+4[/tex]

(ii) Add 4 to the result in (ii).

[tex]28[/tex]

Hence, the correct answer is: Find half the difference of 14 and 6, multiply by 6, then add 4.

Answer:

f(0) is approximately equal to 7.07

Step-by-step explanation:

All you need to do here is substitute a zero wherever you see an x in the equation, giving us:

[tex]f(0) = 2(0)^2 + 5\sqrt{0 + 2}\\f(0) = 5\sqrt{2} \\f(0) \approx 5 \times 1.414\\f(0) \approx 7.07[/tex]

Answer and Step-by-step explanation:

To solve for r, we need to get everything away from r. We can start off by moving five thirds, and pi.

[tex]x = \frac{5}{3} \pi r^{3}[/tex]

Multiply each side by [tex]\frac{3}{5}[/tex], then divide by [tex]\pi[/tex] (pi)

[tex]\frac{3x}{5\pi } = r^{3}[/tex]

Now, take the cubed root of both sides.

[tex]\sqrt[3]{\frac{3x}{5\pi } } = r[/tex]

^^ That is the answer.

Answer:

B x 0.16 = T

If the bill is $ 145, the tip will be $ 23.2.

Step-by-step explanation:

Since Jack’s BBQ has a policy of adding a 16% tip if there is a party of 8 or more, to write an equation to represent the relationship between tip (t) and the bill (b), the following reasoning must be performed:

B x 0.16 = T

B is the value of the bill after consumption.

In turn, to determine how much the tip would be if the bill is $ 145, the following calculation must be performed:

145 x 0.16 = T

23.2 = T

Thus, if the bill is $ 145, the tip will be $ 23.2.
