Write the sentence as an inequality. A number x is no less than –8.
x ≥ -8
Answer choice D is correct
x ≥ -8 represents the given inequality. Option C is correct.
What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here.
A number x in no less than -8,
Implies that the number x must be equal to -8 or more,
Applying the greater equal to sign(≥) between the x and -8
x ≥ -8
Thus, x ≥ -8 represents the given inequality. Option C is correct.

3:5. Then, it sold four times as many fiction books and 40%
more cartoon books. As a result, it sold 800 more fiction books
than cartoon books. How many fiction and cartoon books were
sold altogether in the end?
Complete question:
A book shop sold fiction books and cartoon books at a ratio of 3:5. Then, it sold four times as many fiction books and 40% more cartoon books. As a result, it sold 800 more fiction books than cartoon books. How many fiction and cartoon books were sold altogether in the end?
Answer:
3040
Step-by-step explanation:
Given the following :
Sales ratio = 3:5 (fiction : cartoon)
Let total number of books sold = x
Fiction books = 3x
Cartoon books = 5x
Four times as many fiction books = 4 × fiction books = 4*(3x) = 12x - - - (1)
40% more cartoon books = 40/100 = 0.4
5x(1.40) = 7x - - - (2)
As a result, 800 more fiction books than cartoon :
Fiction - cartoon = 800
12x - 7x = 800
5x = 800
x = 160
Substitute x into (1) and (2)
Fiction books : 12(160) = 1920
Cartoon books : 7(160) = 1120
1920 + 1120 = 3,040
A regular polygon of n sides has its sum of interior
angles as 900° What is n?
A. 5
B.6
C.7
D. 8
Answer:
C. 7Step-by-step explanation:
n is the number of sides of the polygon
[tex](n - 2) \times 180 = 900[/tex]
Divide both sides of the equation by 180
[tex] \frac{(n - 2) \times 180}{180} = \frac{900}{180} \\ n - 2 = 5 \\ n = 5 + 2 \\ n = 7[/tex]

Step-by-step explanation:
You are baking and run out of an important ingredient. Rather than fire up the car, you decide to use a bicycle. The store is 1/2 mile away. Assume your car gets 30 miles to the gallon. If every driver on the planet made a similar decision once per week for a year, approximately how much gas would be saved for that year
Answer:
approximately 1.213 billion gallons of fuel will be saved per year.
Step-by-step explanation:
Distance to the store = 1/2 mile
If my car gets 30 miles to one gallons, then for 1/2 mile my car will use
1/2 ÷ 30 = 1/2 x 1/30 = 1/60 gallons
Statistics puts the number of cars users on Earth to be about 1.4 billion = 1.4 x 10^9 cars
If every driver makes this decision once a week for a year, that will be 52 times a year since there are 52 week in a year.
Total gas that will be saved in one week = 1/60 x 1.4 x 10^9 = 23333333.3 gallons
In a year that will be = 23333333.3 gallons x 52 = 1.213 x 10^9 gallons
that is approximately 1.213 billion gallons of fuel saved per year

Find the value of h(-67) for the function below. h(x) = -49x − 125
Answer:
h(-67) = 3158
Step-by-step explanation:
Simply plug in -67 for x:
h(-67) = -49(-67) - 125
h(-67) = 3283 - 125
h(-67) = 3158
Answer: h(-67) = 3158
Step-by-step explanation:
-49(-67)-125
3283-125

Answer:
Step-by-step explanation:
2x + 17
twice a number 2x
more than: add
Answer:
7 + 2 × a.
Step-by-step explanation:
Take a as the number.
Twice the number means 2 multiplied by the number.
More than means addition.
So, it would be 7 + 2 × a.
It's an equation.

Find the midpoint of the line segment connecting the two points (5,-3) (-4,7)
Answer:
The answer is
[tex]( \frac{1}{2} \: , \: 2)[/tex]Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(5,-3) and (-4,7)
The midpoint is
[tex]M = ( \frac{5 - 4}{2} , \: \frac{ - 3 + 7}{2} ) \\ = ( \frac{1}{2} \: , \: \frac{4}{2} )[/tex]We have the final answer as
[tex]( \frac{1}{2} \: , \: 2)[/tex]Hope this helps you
There are 4,200 butterflies. 800 are orange, 200, purple, 400 are yellow and the rest are blue. What fraction of the butterflies are blue ?
Answer:
2/3 is the answer
Answer:
2/3
Step-by-step explanation:
First you add all the colors. Then you subtract that number from 4200 to get the total number of blue buterfiles. After that, you put the total number of blue butterflies in the numerator and the 4200 would go in the denominator. Then you reduce until u get the final fraction.

PLEASE HELP
Answer:
1/2+1/5=7/10
Step-by-step explanation:
1/2=5/10
1/5=2/10
2/10+5/10=7/10
Answer:
0.7 or 7/10
Step-by-step explanation:
When adding fractions they always need to have the same denominators,and the one they both have similar to is being equal to 10.
1/2 will get multiply with 5 on the numinator and the denominator having you get a fraction of 5/10.
You will do the same with 1/5 multiply it with 2 on the numinator and denominator having you get 5/10.
Since the dneominators are the same you keep it 10,and just add 5 and 2. Giving you a answer of 7/10
What is the value of x in the equation LaTeX: \frac{3}{2}\left(4x-2\right)-3x=5-\left(x+2\right) 3 2 ( 4 x − 2 ) − 3 x = 5 − ( x + 2 ) ?
Answer:
3/2
Step-by-step explanation:
Given the equation 3/2(4x-2)-3x = 5-(x+2)
Open the parenthesis
3/2(4x) - 3/2(2) -3x = 5-x-2
6x-3-3x = 3-x
3x-3 = 3-x
Collect like terms
3x+x = 3+3
4x = 6
Divide both sides by
4x/4 = 6/4
x = 3/2
Hence the value of x is 3/2

What is the length of the given segments EF and GH?
Answer:
[tex] EF = 5 [/tex]
[tex] GH = 5 [/tex]
Step-by-step explanation:
Length of EFis the distance between E(-4, -3) and F (-1, 1).
[tex] EF = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] E(-4, -3) = (x_1, y_1) [/tex]
[tex] F(-1, 1) = (x_2, y_2) [/tex]
[tex] EF = \sqrt{(-1 -(-4))^2 + (1 -(-3))^2} [/tex]
[tex] EF = \sqrt{(3)^2 + (4)^2} [/tex]
[tex] EF = \sqrt{9 + 16} = \sqrt{25} [/tex]
[tex] EF = 5 [/tex]
Distance between G(-2, -3) and H(3, -3)
[tex] GH = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] G(-2, -3) = (x_1, y_1) [/tex]
[tex] H(3, -3) = (x_2, y_2) [/tex]
[tex] GH = \sqrt{(3 -(-2))^2 + (-3 -(-3))^2} [/tex]
[tex] GH = \sqrt{(5)^2 + (0)^2} [/tex]
[tex] GH = \sqrt{25 + 0} = \sqrt{25} [/tex]
[tex] GH = 5 [/tex]
