Hugo took a math test with 40 questions. If he got 75% of the answers correct, how many did he answer incorrectly?

Answer:

x equals 51

Step-by-step explanation:

1. Do the inverse operation of x/-3 which is multipulcation.

2. Multiply -17 by -3 to get the answer of 51.

Finish the equation by saying that x = 51, or 51 = x.

Answer:

X=51

Step-by-step explanation:

You would have to multiply 17 by 3.

10x3=30

7x3=21

then you add 30 and 21 which equals 51

Step-by-step explanation:

Given

[ 6 + ( 10- 8 ) *7 ] + 5

= [ 6 + 2 * 7] + 5

= [ 6 + 14 ] + 5

= 20 + 5

= 25

Answer:

25

Step-by-step explanation:

Using PEMDAS, you start by evaluating the expression in parentheses:

(6 + (2) × 7 ) + 5

Since there are no exponents, you do the multiplication/division next:

(6 + 14) + 5

Then add the rest:

(20) + 5

25

Answer:

0.11

Step-by-step explanation:

To get the probability above, we simply look for the events greater than 4, then add their probabilities

That is;

P(5) + P(6) + P(7)

So the probability in this case will be;

0.07 + 0.03 + 0.01 = 0.11

Answer:

(By mints I hoped you meant candy) 480 packs of gum

Step-by-step explanation:

2 packs of candy for every 6 packs of gum. Divided beach side by two to get ration of 1:3. This means that for every 1 pack of candy 3 packs of gum are sold. 160 x 3 = 480.

Answer:

[tex]x=155[/tex]

Step-by-step explanation:

According to the definition of a linear pair:

[tex](x-25)+(50)=180[/tex]

Solve for [tex]x[/tex].

Combine like terms on the left:

[tex]x+25=180[/tex]

Subtract 25 from both sides:

[tex]x=155[/tex]

Hence, the value of [tex]x[/tex] is 155.

Answer:

x=155, the angle is 130 degrees

Step-by-step explanation:

Assuming you want to find x:

A straight line is 180 degrees so that means

x-25+50=180 add like terms together

x+25=180 subtract 25 from both sides

x=155

If you want to find the degree angle, just replace x with 155

x-25=155+25=130

Also if you want to know, yes I edited my answer as I couldn't tell if that was a + or a - in the picture. Have a nice day and happy thanksgiving!

Answer:

b = -4

Step-by-step explanation:

your equation: -4b + 2 = 18

subtract 2 from both sides: -4b = 16

divide both sides by -4 to isolate the variable: b = -4

Answer:

b= -4b=18-2

=16

b=16+(-4)

=12

Step-by-step explanation:

350-105.20= 244.80 is still needed

I don't have the statements so...

244.80/18 weeks = 13.60 She'll need to save at least $13.60 a week for 18 weeks to make up the difference.

Answer:

Step-by-step explanation:

18x + 105.2 ≥ 350

18x ≥ 244.8

x ≥ 13.6

She has to save at least $13.6 per week.

Answer:

C

Step-by-step explanation:

Answer: x = -10 or 2

Step-by-step explanation:

Given:

√20 - 8x = x

Step 1: Square √20 - 8x

(√20 - 8x)² = (x)²

20 - 8x = x²

Now we can solve the problem

Step 2: Move 20 - 8x to the other side

20 - 8x = x²

-20 + 8x   - 20 + 8x

0 = x² + 8x - 20

This is a quadratic equation

Step 3: Factor the quadratic equation

10(-2) = -20 and 10 - 2 = 8

So our factors are 10 and -2

(x + 10)(x - 2) = 0

Step 4: Create a FOIL equation

For this equation to be true, x would have to make either one of the parenthysis equal to zero

(x + 10)(x - 2)

x = -10 x = 2

10 - 10 equals zero, and -2 + 2 equals zero, so those are your answers.

Answer:

I think the answer would be 5.4 squared would be 80. ( 5.4) squared would be 400. And (3.4) squares would be 114. I hope that this helps.

Answer:

The ordered pair is (4,6)

Step-by-step explanation:

Ordered Pairs

It's given the equation

y = x + 2

Since there are no restrictions for the values of x and y, it has infinitely many solutions, i.e. any ordered pair of values (x,y) that make true the equation is a solution.

We can pick any value for x and then calculate the corresponding value for y as follows:

For x = 4,

y = 4 + 2 = 6

The ordered pair is (4,6)

Answer:

Step-by-step explanation:

1/(x^4) or x^-4

Answer:

[tex]\frac{1}{x^{4}}[/tex]; x ≠ 0

Or if thats wrong, just put 1/x^4

Step-by-step explanation:

Okay so heres how we solve this

Rewrite:

The "x is a non zero" is a very poorly written exception so I completely understand if you started racking your brain over that

[tex]x^{-10}*x^6[/tex] ;  x ≠ 0

Note; you can ignore the expression until you write the simplified answer.

1 - Multiply using rules of exponents

[tex]x^{-10} * x^6 = x^{(-10~+~6)} = x^{-4}[/tex]

2 - Get rid of the negative exponent by using rules of exponents

[tex]x^{-4} = \frac{1}{x^4}[/tex]

3 - Rewrite with it being simplified

1/(x^4); x ≠ 0
