Answer:

D

Step-by-step explanation:

The solution is, the value of x is, D) x ≤ -30.

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

given that,

x + 20 ≤ -10

now, we have to solve this,

at first we subtract 20 from both sides, we get,

x + 20 - 20  ≤ -10 -20

or, x  ≤ -30

Hence, The solution is, the value of x is, D) x ≤ -30.

Step-by-step explanation:

multiply 6 time 90 which gives you 180

72x + 436= -96x + 1108x

72x+436=1012x

436=1012x−72x

436=940x

436/940=x

109/235=x

x=109/235

Hope this helps have a blessed and wonderful day!

Answer:

x=4

Step-by-step explanation:

72x+436=-96x+1108

or,72x+96x=1108-436

x=672/168

x=4

Step-by-step explanation:

f(x) = 2x^2 - 7x + 3

f(0) = 2(0)^2 - 7(0) + 3

= 0 + 0 + 3

= 3

f(x) = 2x^2 - 7x + 3

f(-2) = 2(-2)^2 - 7(-2) + 3

= 8 + 14 + 3

= 25

Answer:

[tex]\huge\boxed{\dfrac{4}{7};\ \dfrac{5}{8};\ 0.7;\ 72\%}[/tex]

Step-by-step explanation:

Two ways.

1. Convert to the decimal:

[tex]\dfrac{4}{7}=4:7=0.\overline{571428}\\\\\dfrac{5}{8}=5:8=0.625\\\\0.7=0.7\\\\72\%=\dfrac{72}{100}=0.72[/tex]

therefore

[tex]0.\overline{571428}<0.625<0.7<0.72}[/tex]

[tex]\dfrac{4}{7};\ \dfrac{5}{8};\ 0.7;\ 72\%[/tex]

2. Convert to the fractions with common denominator.

[tex]\dfrac{4}{7};\ \dfrac{5}{8}\\\\0.7=\dfrac{7}{10}\\\\72\%=\dfrac{72}{100}=\dfrac{18}{25}[/tex]

[tex]LCD=7\cdot8\cdot5\cdot5=1400\\\\\dfrac{4}{7}=\dfrac{4\cdot200}{7\cdot200}=\dfrac{800}{1400}\\\\\dfrac{5}{8}=\dfrac{5\cdot175}{8\cdot175}=\dfrac{875}{1400}\\\\0.7=\dfrac{7}{10}=\dfrac{7\cdot140}{10\cdot140}=\dfrac{980}{1400}\\\\72\%=\dfrac{72}{100}=\dfrac{72\cdot14}{100\cdot14}=\dfrac{1008}{1400}\\\\\dfrac{800}{1400}<\dfrac{875}{1400}<\dfrac{980}{1400}<\dfrac{1008}{1400}[/tex]

therefore

[tex]\dfrac{4}{7};\ \dfrac{5}{8};\ 0.7;\ 72\%[/tex]

Answer:

35/6

Step-by-step explanation:

The result of dividing 5/6 by 1/7 is 35/6.

Here, we have,

To divide fractions, we can use the following rule:

To divide one fraction by another, we multiply the first fraction by the reciprocal of the second fraction.

In this case, we have:

(5/6) ÷ (1/7)

To find the reciprocal of a fraction, we simply flip the fraction by swapping the numerator and denominator.

Therefore, the reciprocal of 1/7 is 7/1.

Now, we can rewrite the expression as a multiplication:

(5/6) * (7/1)

Multiplying the numerators and denominators:

(5 * 7) / (6 * 1)

Simplifying:

35/6

Therefore, the result of dividing 5/6 by 1/7 is 35/6.

The value of  g(x) = 2x² - 4, when g(-2) = 4

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.

Given:

g(x) = 2x² - 4

The above function is a quadratic function.

The solution of when g(-2):

Substituting the value of x = -2

 g(x) = 2x² - 4

g(x) = 2(-2)² - 4

g(x) = 8 - 4

g(x) = 4

Therefore, the value of g(-2) = 4.

Answer:

That their milkshakes need more caramel or less ice cream.

Step-by-step explanation:

We can see that Ari's numbers for a perfect milkshake gives us a caramel to ice cream ratio of 333 / 555 = 0,6.

But the Freeze Zone uses a caramel to ice cream ratio of 666 / 888 which is equal to 0,75.

Their milkshakes have less caramel and more ice cream than Ari's perfect milkshake so Ari will think that Freeze Zone's milkshakes are not sweet enough.
