Answer:

10

Step-by-step explanation:

→ Expand brackets

-5.4 + 0.55x = 0.05x - 0.4

→ Minus 0.05x from both sides

-5.4 + 0.5x = -0.4

→ Add 5.4 to both sides

0.5x = 5

→ Divide both sides by 0.05

x = 10

Given that Bill saves 1/8 of his $92 income, the amount of money he saves is $11.5.

Given that;

Let the amount saved by be be represented by the variable x.

Hence,

1/8 of Bill's income = Amount saved

1/8 × $92 = x

Multiply the numerators

x = 1/8 × $92

x = $92/8

Divide 92 by 8

x = $11.5

Given that Bill saves 1/8 of his $92 income, the amount of money he saves is $11.5.

The inverse operation for given sentences are 48 ÷ 8 = 6 and 14 + 15 = 29

Inverse operations, such as addition and subtraction, multiplication and division, are pairs of mathematical operations where one operation reverses the effect of the other. The term "inverse" refers to the reciprocal of a number, i.e., x - 1 = 1 / x. One results from multiplying a number by its reciprocal, or inverse. The impact of one operation on another is reversed by using inverse operations.

The inverse operation for the the equations are -

a) 6x8 = 48

⇒ 48 ÷ 8 = 6

b) 29-15 = 14

⇒ 14 + 15 = 29

Answer:

35/8

step 1: turn the mixed fraction to an improper fraction =29/8

step 2: divide 29 by 8 ,it gives you 3

that and a remainder of 5 don't forget to place your decimal piont

step 3:place 0 at the back of 5 it then becomes 50 so we can easily divide 8 by 50

50 divided by 8 is 6 that gives a remainder of 2

step 3:place 0 at the back of 2 like earlier then it becomes 20

divide 20 by 8 ,this gives you 2 and a remainder of 4

step 4:place 0 at the back of 4 as done earlier , divide 40 by 8

it gives you 5 with no remainder

so your answer finally becomes 3+0.625 which is 3.625

The statement that the inequality is d<-60 or(-60>d) is; true.

Let d represent the depth of the researchers' second dive.

We are given that;

Depth of First dive = -60 ft

It was stated that in their second dive, the researchers explored a deeper depth, that is depth deeper than 60 ft.

Since the depth of 60ft is represented by the integer -60, then deeper depth would be represented by integers less than -60.

Thus, we can conclude that d can be represented with the inequality;

d < -60

Therefore the statement that d<-60 or(-60>d) is true.

The digit at unit's place of odd number should be 1 to be divisible by 5  and have remainder 1.

Odd numbers are the numbers that cannot be divided into two equal parts.

In odd numbers the digits in the units place always remains 1,3,5,7 and 9.

According to the question the odd number is divided by 5 and the remainder is 1.

For the number to be divisible by 5 and have remainder 1 the digit that must be in the unit place will be 1

If we see all the digits in units place of odd numbers then 1 is the only possibility as if it is 3 then the remainder will be 3. If it is 5 then the remainder will be 0, if it is 7 then the remainder will be 2 and if it is 9 then the remainder will be 4.

Hence the digit at unit's place of odd number should be 1.

The runners would be able to run 2 times back and forth from the earth to the moon if their distances were added.

An equation is an expression that shows the relationship between two or more numbers and variables.

There are 50,304 runners and each runner runs a distance of 26.2 miles. Hence:

Total distance ran by runners = 26.2 miles * 50304 = 1317964.8 miles.

The distance from the earth to the moon is 2.389 x 10⁵ miles, hence:

Ratio of total distance to distance from earth to moon = 1317964.8 miles/ (2.389 * 10⁵) = 5.516

Time ran back and forth = 5.516 / 2 = 2.76

Step-by-step explanation:

Answer:

No solution for x

Step-by-step explanation:

Subtract 7 from both sides
==> [tex]5\left|x+1\right|+7-7=-38-7[/tex]

==> [tex]5\left|x+1\right|=-45[/tex]

Divide both sides by 5
==>   [tex]\frac{5\left|x+1\right|}{5}=\frac{-45}{5}[/tex]

==>  [tex]\left|x+1\right|=-9[/tex]

But this is not possible since absolute value cannot be negative

Hence the equation is inconsistent and therefore there are no solutions for x

Answer:

No solution

Step-by-step explanation:

5|x+1| + 7 = -38

5|x+1| = -38 - 7

5|x+1| = -45

Divide both sides by -5

|x + 1| = -9

Because of how the modulus works, whatever is inside it, whether positive or negative, will become positive.

And since the left side is always positive and the right side is always negative, there is no value of x that can satisfy the equation.

Therefore there is no solution to this equation

The function composite h(x) = f(x)g(x) is -10x² +  40x.

Option b)-10x² +  40x is the correct answer.

Given the functions in the question;

Since h(x) = f(x)g(x), replace the function designators in f(x)g(x) with the actual functions.

h(x) = f(x)g(x)

h(x) = ( 2x - 8 )( -5x )

Apply distributive property.

h(x) = ( 2x - 8 )( -5x )

h(x) = 2x(-5x) - 8(-5x)

Answer:

No

Step-by-step explanation:

A right triangle needs to have a right angle in this case this triangle does not. The next answer up is a triangle with 6,8, and 10 inches. This would give you a right triangle.

Also, To check if the sides are a right triangle, check if the sum of the squares of the two smaller sides equals the length of the square of the longest side.

I haven't used triangles in a long time..... so I kinda forget but the little I remember I used. Hope this helps!

Answer: No

Step-by-step explanation:  The given side lengths of the triangle are 4 inches, 6 inches, and 9 inches. To determine if the triangle is a right triangle, we can use the Pythagorean theorem.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Let's check if the given side lengths satisfy the Pythagorean theorem:

Using the Pythagorean theorem, we can calculate the squares of the side lengths:

4^2 = 16

6^2 = 36

9^2 = 81

Now, let's compare the sum of the squares of the two shorter sides to the square of the longest side:

16 + 36 = 52

81 = 81

Since 52 is not equal to 81, the given triangle is not a right triangle.
