Answer:22

Step-by-step explanation:

Answer:

x=22

Step-by-step explanation:

add 38 to both sides

you'll have 3x=66 after adding

then divide both sides by three so have x by itself and you'll get

x=22

Answer:

50+12x≥158

Step-by-step explanation:

starting with $50, adding $12 for every car washed (x), must be at least, but can be greater than, $158.

The required inequality for Silvio to earn more than $158 in one day is, $50 + 12x ≥ 158.

Given that,
Silvio works at a car wash. He earns $50 per day and $12 per car washed. Silvio wants to earn at least $158 in 1 day.
To determine the inequality represents the number of cars (C) Silvio must wash to reach his goal.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
Let the number of cars washed by Silvio be x,
According to the question,
Silvio works at a car wash. He earns $50 per day and $12 per car washed.
Total earning of the day = $50 + 12x
Silvio wants to earn at least $158 in 1 day. So, his total earnings of the day must be greater equal to $158.
$50 + 12x ≥ 158.

Thus, the required inequality for Silvio to earn more than $158 in one day is, $50 + 12x ≥ 158.

Answer:

Area=15in²

Perimeter=16in

Step-by-step explanation:

area=L×W

Perimeter=L+L+W+W

Answer:

Your answer is

Area  =  ( 5 * 3) = 15 inch ^2

Perimeter = 2(5+3) = 16 inch

Step-by-step explanation:

Answer:

The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0. When the product of factors equals zero, one or more of the factors must also equal zero. Once the polynomial is factored, set each factor equal to zero and solve them separately.

Answer:

D-$4,900

Step-by-step explanation:

Answer:

The answer is D. $4,900

Step-by-step explanation:

$196 in commissions  => a = 196

s = a / 0.04 = 196 / 0.04 = $4900 = Ann's sales

so the answer for Ann's sales is $4,900

Answer:

Probability of spinning a odd number is 5/9

I don't know about flipping head

Probability of spinning a 3 is 1/9

=========================================================

Explanation:

The sample space of the spinner is {1,2,3,4,5,6,7,8,9} which represents all the possible outcomes. We can only pick one of those values. Of that list, the subset {1,3,5,7,9} represents all the odd numbers. This is the event space because we want to land on an odd number.

There are 5 items in the event space and 9 items in the sample space. The probability of getting an odd number is 5/9.

The probability of flipping heads is 1/2 since we have one side we want (heads) out of two sides total.

Lastly, the probability of landing on a '3' is 1/9 because there's only one '3' out of 9 values total.

---------

We'll multiply those fractions to get the final answer. This works because each event is independent of one another.

(5/9)*(1/2)*(1/9) = (5*1*1)/(9*2*9) = 5/162

Now use your calculator to find that: 5/162 = 0.030864 approximately which rounds to 0.0 or just 0 when rounding to the nearest tenth.

Unfortunately this is one case where rounding will creates a misleading result. The true probability isn't 0 because the events described are possible. The probability is just really small.

Answer:

x has the values -4 and -3

Step-by-step explanation:

x² + 7x + 12 = 0

x² + 3x + 4x + 12 = 0

x(x + 3) + 4(x + 3) = 0

(x + 4)(x + 3) = 0

Answer:

are you sure those are all the options because it is -82

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the equation is, y = x² + bx + c

Here, b = Sum of the roots

And c = multiplication of the roots

Roots of the equation are (5 + 2i) and (5 - 2i).

Step 1,

Sum of the roots 'b' = (5 + 2i) + 95 - 2i)

                             b = 10

Step 2,

Multiplication of the given roots = (5 - 2i)(5 + 2i)

                                                     = 5² - (2i)²

                                                     = 25 + 4

                                                     = 29

Step 3

Therefore, equation of the quadratic function will be,

y = x² + 10x + 29

Answer:

3√512 = 8

Step-by-step explanation:

Step 1: Find the prime factors of 512

512 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2

Step 2: Pair the factors of 512 in a group of three, such that they form cubes.

512 = (2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2)

512 = 23 × 23 × 23

Using the law of exponent, we get;

512 = 29 [am.an = (a)m+n]

Or

512 = (23)3 [(am)n = amn]

512 = 83

Step 3: Now, we will apply cube root on both the sides to take out the factor (in cubes) as a single term.

3√512 = 3√(83)

So, here the cube root is eliminated by the cube of 8.

Hence, 3√512 = 8
