Answers

You would just do inverse operations. The answer would be x = -54

Multiply the entire thing by-3 so there are no fractions, this will equal x+24=-30. Now isolate x. Subtract 24 from each side so you will come out with x=-54

Assume each tick mark represents 1 cm. Calculate the total displacement from 0 if an object moves 3 cm to the left, then 7 cm to the right, and then 6 cm to the left

Answers

Moving 3 cm to the left would be "-3", then 7 to the right makes it "4" and 6 to the left makes it "-2", so it would be 2 centimeters behind 0, the total displacement is "2" (negative doesn't apply because you can't be -2 cm away from something)

Answer:

Calculate the final displacement from 0 if an object first moves 3 cm to the left and then 5 cm to the right.

The final displacement is 2 cm to the RIGHT .

Step-by-step explanation:

the second of three numbers is 1 less than the first. The third number is 5 less than twice the second. If the number exceeds the first number by 12, find the three numbers

Answers

The three numbers are found by forming and solving a system of equations: the first number is 19, the second is 18 (which is one less than the first), and the third is 31 (which is 5 less than twice the second and exceeds the first by 12).

To solve the problem of finding the three numbers, we can set up a system of equations based on the information given:

The first number is x.The second number is one less than the first, so it is x - 1.The third number is 5 less than twice the second, which translates to 2(x - 1) - 5.The third number also exceeds the first by 12, so 2(x - 1) - 5 = x + 12.

Now we can solve for x:

2(x - 1) - 5 = x + 122x - 2 - 5 = x + 122x - x = 12 + 2 + 5x = 19

The first number is 19. The second number is 18 (19 - 1), and the third number is 31 (2(18) - 5).

Thus, the three numbers are 19, 18, and 31.

You want to make a large bowl of salad to share with your friends. Your brother eats 1/3 of it before they come over.

a.) you want to divide the leftover salad evenly among six friends. What expression describes the situation? Exlplain.

Lets think the entire bowl of salad as 1 unit. Now your brother eats one-third. So the remaining salad is 1 minus 1/3 . And now you want to divide the remaining salad evenly among 6 friends. so it is 1-(1/3) divided by 6. To put it in one single expression, it is (1-(1/3)) / 6

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

The number is 900% of it is 450.

let the number be x.

900% of x= 450

900/ 100 x= 450

9x = 450

x= 50

Hence, 900% of 50 is 450.

Would you solve the equation 0.25x + 7 = 1/3x -1 using fractions or decimals? Explain. Please help I'm very confused! #40

Answers

You would use fractions in my opinion.
0.25 is easy to change to a fraction. It's 1/4
However, 1/3 is not easy to change to a decimal because it would be the repeating decimal 0.333333(going on forever).

So basically it's just easier to change them both to fractions because 1/3 isn't a terminating decimal.

I would use fractions because 0.25=1/4 but 1/3=0.3333333333333 forever

also, we can cancel fractions by multiplying by the least common denomenator

so, write 0.25x as 1/4x

1/4x+7=1/3x-8
times both sides by 12
3x+84=4x-96
minus 3x both sides
84=x-96
add 96 to both sides
180=x
x=180

Is the expression a12 a4 equivalent to a8 a8?

Answers

Final answer:

The expressions a12 a4 and a8 a8 are equivalent because according to the laws of exponents, when multiplying terms with the same base, you add their exponents, resulting in both expressions equating to a16.

Explanation:

The question refers to whether the expressions a12 a4 and a8 a8 are equivalent. These expressions are using the laws of exponents, specifically, the rule which states that when you are multiplying terms with the same base, in this case, a, you add their exponents. Therefore, a12 a4 would actually equal a16 because 12 + 4 equals 16. Similarly, a8 a8 would equal a16 because 8 + 8 equals 16, so yes, these expressions are equivalent as they both simplify to a16.

The volume of a box for earrings is 216 cubic centimeters. What is the length of one edge of the box plz help it's due tm

Answers

I’m pretty positive you divide 216 by 4, since that’s the amount of sides a box normally has. The answer would be 54 cubic centimeters. Please let me know if I’m correct, hopefully this helped.

Answer:

side of the cubic box is 6 cm

Step-by-step explanation:

The volume of a box for earrings is 216 cubic centimeters.

Volume of a cubic box is [tex](side)^3[/tex]

[tex]Volume = a^3[/tex], where 'a' is the side of the cubic box

[tex]216 = a^3[/tex]

Take cube root on both sides

[tex]\sqrt[3]{216} =\sqrt[3]{a^3}[/tex]

Cube and cube root will get cancelled

So 6=a

The side of the cubic box is 6 cm

A safety regulation states that the height h of a guardrail should be 106 centimeters with an absolute deviation of no more than 7 centimeters. Write and solve an absolute value inequality that represents the acceptable heights of a guardrail.

Answers

The expected height is h = 106 cm.
The absolute deviation is 7 cm.

Therefore the range of acceptable heights, h, is
x ≥ 106 - 7 or x ≥ 99 cm

Also,
x ≤ 106 + 7 = 113 cm

Therefore acceptable heights are defined by
99 ≤ x ≤ 113 cm

Answer: 99 ≤ h ≤ 113 cm

A 7/1 and for B turn minutes into seconds. 10 min * 60 = 600 seconds and now 7 times 600 seconds = 4200 feet

The submarine's elevation after 10 minutes is 4200 feet if the Navy submarine descended from sea level at a rate of seven feet per second.

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

A Navy submarine descended from sea level at a rate of seven feet per second writing the descendent rate as an integer.

The rate of drop is 7 feet per second. 7 x 10(60), or 7 x 600, would be the subs elevation.

Consequently, the sub's elevation would be 4,200 feet below sea level.

Thus, the submarine's elevation after 10 minutes is 4200 feet if the Navy submarine descended from sea level at a rate of seven feet per second.
