Answer:

-4

Step-by-step explanation:

-4(3) = -12

-12 + 8 = -4

After solving the algebraic equation, the unknown number is equal to -4.

To write the word problem as an algebraic equation:

In this exercise, we are required to translate the given word problem into a mathematical (algebraic) expression and then solve for the unknown variable (number):

Translating the word problem into an algebraic expression, we have;

Eight more than three times a number:

[tex]3x + 8[/tex]

Equating the above to the number, we have:

Answer:

5

Step-by-step explanation:

Answer:

y+8=-5(x-3)

Step-by-step explanation:

The formula for point-slope form is y-y1=m(x-x1)

The points for (x1, y1) are (3, -8), meaning that 3 is x1 and -8 is y1.

So, start by writing your equation like this: y--8=m(x-3)

For the equation y--8=m(x-3), the y--8 will change to a + sign because two negatives make a positive, right? So, the equation should now look like this: y+8=m(x-3).

We know that the slope (m) is -5. Plug that into the equation to get this: y+8=-5(x-3)

And there you have it!! The equation is now in point-slope form!!

y+8=-5(x-3) is the final answer!!

Answer: -1t + 720

Step-by-step explanation:

He worked at both jobs for 90 hours for this month.

He worked t hours as a tutor which means that as a waiter he worked;

= 90 - t hours

The amount earned is therefore;

= 7t + (8 * (90 - t))

= 7t + 720 - 8t

= -1t + 720

Step-by-step explanation:

Answer:

C = 48.5° ; B = 131.5°

Step-by-step explanation:

When any two angles are supplementary , it means that their sum is equal to 180°.

It's given in the question that B is 83 more than C . So,

[tex]B = C + 83[/tex]

Also it's given in the question that B & C are supplementary angles.

[tex]=> B + C = 180[/tex]

[tex]=> C + 83 + C = 180[/tex]

[tex]=> 2C = 180 - 83 = 97[/tex]

[tex]=> C = \frac{97}{2} = 48.5[/tex]

Hence,

[tex]B = 83 + 48.5 = 131.5[/tex]

∴ C = 48.5° ; B = 131.5°

Answer:

[tex]\%Increase = 118\%[/tex]

Step-by-step explanation:

Given

[tex]Initial\ Weight = 550g[/tex]

[tex]First\ Addition = 350g[/tex]

[tex]Second\ Addition = 300g[/tex]

Required

Determine the percentage increment

First, we have to calculate the new weight

[tex]New\ Weight = Initial\ Weight + First\ Addition + Second\ Addition[/tex]

[tex]New\ Weight = 550g + 350g + 300g[/tex]

[tex]New\ Weight = 1200[/tex]

The percentage increment is then calculated as:

[tex]\%Increase = \frac{New\ Weight - Initial\ Weight}{Initial\ Weight} * 100\%[/tex]

[tex]\%Increase = \frac{1200g - 550g}{550g} * 100\%[/tex]

[tex]\%Increase = \frac{650g}{550g} * 100\%[/tex]

[tex]\%Increase = \frac{650}{550} * 100\%[/tex]

[tex]\%Increase = 1.182* 100\%[/tex]

[tex]\%Increase = 118.2\%[/tex]

[tex]\%Increase = 118\%[/tex] -- Approximated

Hence, the percentage increment is approximately 118%

Answer:

[tex]f(g(-7))=10[/tex]

Step-by-step explanation:

We have the two functions:

[tex]\displaystyle f(x)=\frac{1}{3}x+7\text{ and } g(x)=-2x-5[/tex]

And we want to find:

[tex]f(g(-7))[/tex]

So, we will first find g(-7). We know that:

[tex]g(x)=-2x-5[/tex]

Then by substitution:

[tex]g(-7)=-2(-7)-5[/tex]

Evaluate. Multiply:

[tex]g(-7)=14-5=9[/tex]

Therefore, we can rewrite our expression as:

[tex]f(g(-7))=f(9)[/tex]

Since we know that:

[tex]\displaystyle f(x)=\frac{1}{3}x+7[/tex]

By substitution:

[tex]\displaystyle f(9)=\frac{1}{3}(9)+7[/tex]

Evaluate:

[tex]f(9)=3+7=10[/tex]

Therefore:

[tex]f(g(-7))=10[/tex]

Answer:

[tex]\boxed {\boxed {\sf f(g(-7))= 10}}[/tex]

Step-by-step explanation:

We are asked to find f(g(-7)) given these 2 functions:

We must work from the inside out, so first find g(-7).

1. g(-7)

The function for g is:

[tex]g(x)= -2x-5[/tex]

Since we want to find g(-7), plug -7 in for x.

[tex]g(-7)= -2(-7)-5[/tex]

Solve according the PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Multiply -2 and -7.

[tex]g(-7)=14-5[/tex]

Subtract 5 from 14.

[tex]g(-7)=9[/tex]

2. f(9)

Refer back to the original problem: f(g(-7))

Since we found that g(-7) is 9, we can substitute 9 in: f(9)

The function for f is:

[tex]f(x)= \frac{1}{3} x+7[/tex]

Plug 9 in for x.

[tex]f(9)=\frac{1}{3}(9)+7[/tex]

Solve according to PEMDAS and multiply 1/3 and 9.

[tex]f(9)=3+7[/tex]

Add 3 and 7.

[tex]f(9)=10[/tex]

f(g(-7) is equal to 10

Answer:

44,39 in

Step-by-step explanation:

To find the space diagonal (whatever it's called in English) you begin looking at the bottom of the box. We want to know the diagonal since the diagonal is one of the sides of the other triangle.

To do this we can start by using trigonometry. (SOH-CAH-TOA)

We need to use Sin t. (Since we wanna know the hypothenuse and we have the opposite.)

So...

Sin(40) = 24 in ÷ h

Then we need to actually be able to calculate this, which we will be able to do if we multiply with h on both sides.

hSin(40) = 24 in

Like that. And now we can divide both sides with Sin(40). So we calculate 24 in devided by Sin(40).

h = 24 in ÷ Sin(40) = 37,34 in

Okay so now we now the diagonal, 37,34 in. Now we can use Pythagorean theorem. (2a+2b=2c and c = square root of (2a+2b))

37,34 in^(2) + 24 in^(2) = 1970,28

And now we take the square root of 1970,28.

Which is about 44,39 in.

Answer:

Spelling word questions = 10

vocabulary word questions = 16

Step-by-step explanation:

Let

Spelling word questions = x

vocabulary word questions = y

Total points = 100

Total questions = 26

x + y = 26 (1)

2x + 5y = 100 (2)

From (1)

x = 26 - y

Substitute x = 26 - y into

2x + 5y = 100

2(26 - y) + 5y = 100

52 - 2y + 5y = 100

- 2y + 5y = 100 - 52

3y = 48

y = 48 / 3

= 16

y = 16

Substitute y = 16 into

x + y = 26

x + 16 = 26

x = 26 - 16

= 10

x = 10

Spelling word questions = 10

vocabulary word questions = 16
