Simplify the inequality:
-12.4x+8x > -0.4x-5.2-2.7
Answers
Answer:
x < 1.975Explanation:
-12.4x + 8x > -0.4x - 5.2 - 2.7
Add similar elements: -12.4x + 8x = -4.4x
-4.4x > -0.4x - 5.2 - 2.7
Subtract -5.2 - 2.7: -7.9
-4.4x > -0.4x - 7.9
Multiply both sides by 10
-4.4x · 10 > -0.4x - 7.9 · 10
Refine
-44x > -4x - 79
Add 4x to both sides
-44x + 4x > -4x - 79 + 4x
Simplify
-40x > -79
Multiply both sides by -1 (Reverse the inequality)
-40x (-1) > -79 (-1)
Simplify
40x < 79
Divide both sides by 40
40x / 40 < 79 / 40

x < 1.975what number must you add to complete the square?
x^2+14x=3
Answers
Answer: 49
Step-by-step explanation: In order to complete the square, you need a perfect square trinomial on the left side of the equation.
The question is, what is the number we need?
Well it comes from a formula. The number that is added to both sides
comes from half the coefficient of the middle term squared.
So that's half of 14 which is 7, squared which is 49.

Given function
y = c*a^xThe points (-1, 1/6) and (1, 2/3) lie on the graph
Substitute the values of x and y to get the system of equations:
1/6 = c*a^(-1) ⇒ 1/6 = c/a ⇒ a = 6c2/3 = c*a^1 ⇒ 2/3 = acSubstitute a and solve for c:
2/3 = 6c*c1/9 = c²c = √1/9c = 1/3Find a:
a = 6c = 6*1/3 = 2The equation of the function:

The Jackson family is driving from Boston to New York for a summer vacation trip. So far, they have driven 84 miles which is 40% of the total miles of their trip. How many total miles is the Jackson’s trip from Boston to New York?
Answers
The answer you are looking for is 210 miles.
To find this answer you must first make 40% into a decimal. To do so, simply divide 40 by 100. This will give you 0.4.
Next, you divide 84 by 0.4. You divide because the percentage of a number is found by multiplying said number by the decimal form of the percent. Since we arent looking for the percentage of a number, but rather the number from which the percentage came, we do the opposite operation.
84 ÷ 0.4 = 210. Thus meaning 210 miles is your answer.
I hope this helps!
The total number of miles that Jackson’s trip from Boston to New York will be 210 miles.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
The Jackson family is driving from Boston to New York for a summer vacation trip. So far, they have driven 84 miles which are 40% of the total miles of their trip.
Let x be the total number of miles. Then the equation is given as,
0.40x = 84
Simplify the equation, then we have
x = 84 / 0.40
x = 210 miles

Answer:

Step-by-step explanation:
To get from 11 in. to 88 in. (from plans to real life), you multiply by 8.
Therefore, to get from 160,160 to ?? (from real-life to plans), you would divide by 8.
160,160 / 8 = 20,020
To check, you can multiply 20,020 by 8 to go from plans to real-life measurements; 20,020 • 8 = 160,160)

What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
Ms. Cathy bought a package of pencils.
And, Out of every 10 pencils, 8 are black. .
Since, There are 30 pencils in the pack,
Hence, The percent of the pencils in the pack are black is,
⇒ 24 / 30 x 100
⇒ 2400 / 30
⇒ 80%
And, The fraction of the pencils in the pack is black is,
⇒ 8 / 10 = x / 30
⇒ 240 = 10x
⇒ x = 24
Thus, The fraction of the pencils in the pack is black is,
⇒ 24 / 30

Elisa is making strawberry shortcake. One serving of strawberry shortcake requires one third cup of strawberries and one shortbread biscuit to feed one person. Elisa has a dozen shortbread biscuits and three cups of strawberries. How many people can Elisa serve strawberry shortcake to? How many cups of strawberries will Elisa need if she wants to use all dozen shortbread biscuits? Show all your mathematical thinking.
PLEASE HELP!
Answers
Given, To make a strawberry shortcake for one person, we need :
▪︎[tex] \frac{1}{3} [/tex] cup of strawberry
▪︎one shortbread biscuit
Quantity of strawberries Elisa has = 3 cups
Number of shortbread biscuits she has = 12
Number of shortcakes she can make :
[tex] = \tt3 \div \frac{1}{3} [/tex]
[tex] = \tt\frac{3 \times 3}{1} [/tex]
[tex]\color{plum} =\tt 9 \: people[/tex]
Thus, Elisa can serve strawberry shortcakes to 9 people.
With 12 dozen shortbread biscuits she can serve 12 people.
Quantity of strawberries needed to serve 12 people :
[tex] =\tt \frac{1}{3} \times 12[/tex]
[tex] =\tt \frac{12}{3} [/tex]
[tex]\color{plum} = \tt4 \: cups[/tex]
○=> Therefore :▪︎Elisa can serve strawberry shortcakes to 9 people.
▪︎Elisa will need 4 cups of strawberries if she wants to use all dozen shortbread biscuits.
