Answer:

x=9   :))

Step-by-step explanation:

First set up your equation.

"3 times" is multiplication

"THE SUM of A NUMBER and seven" that is parenthesis because of the multiplication before it

"is increased by ten" that is an addition at the end

Now we have 3(x+7)+10=4

Solve your equation!

Distribute the 3 now we have 3x+21+10=4

Add like terms

now it should look like this... 3x+31=4

Subtract 31 from both sides and it looks like...

3x=27

Divide by the x-value

x=9

The value of the number will be -9.

What is an expression?

Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that;

The word expression is;

''Three times the sum of a number and seven is increased by ten, the result is four. ''

Now, Let a number be x.

Then, we can formulate the expression as;

3 (x + 7) + 10 = 4

Solve the expression for x as;

3 (x + 7) + 10 = 4

3x + 21 + 10 = 4

3x + 31 = 4

3x = 4 - 31

3x = -27

x = -9

Thus, The value of the number will be -9.

Answer:

h(x) = 2x² - 2x - 8

Step-by-step explanation:

Step 1: Write out equation

h(x) = 2(x + 1)(3x - 4)

Step 2: FOIL

h(x) = 2(x² - 4x + 3x - 4)

Step 3: Combine like terms (x)

h(x) = 2(x² - x - 4)

Step 4: Distribute

z = 7 and w = 10

Equation:

7z + 10w

Substitution:

49 + 100

Answer:

149

Hope this helps :)

The required value of the given expression at z = 7 and w = 10 is given as 179.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Given expression,
z = 7 and w = 10

Now put these values in the given expression,
= 7z + 10w

= 7 × 7 + 10 × 10
= 49 + 100
= 149

Thus, the required value of the given expression is given as 179.

Answer:

r = - 2

Step-by-step explanation:

Use the slope formula to find m then equate to - 1

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (6, r) and (x₂, y₂ ) = (9, - 5)

m = [tex]\frac{-5-r}{9-6}[/tex] = [tex]\frac{-5-r}{3}[/tex]  = - 1 ( multiply both sides by 3 )

- 5 - r = - 3 ( add 5 to both sides )

- r = 2 ( multiply both sides by - 1 )

r = - 2

mike's final position relative to the ground is 3 feet's underground

Step-by-step explanation:

We take positive value when he is above the ground and then take negative value when he is below or underground

6 feet's underground = -6

He climbs up 14 feet = +14

He climbs down 11 feet = -11

We are required to find his last position relative to ground level

= -6+14-11

= (-6) + (-11) + 14

= -17 + 14

= -3

So we have it that mike's final position relative to the ground is 3 feet's underground

Answer:

it should be 2nd option, 3rd, and 5th.

Step-by-step explanation:

From the given options

options I, III and IV  are Arithmetic sequences.

Given :

we are given with sequences. we need to check which one is arithmetic sequence.

A sequence is arithmetic when the consecutive terms have common difference.

Lets check one by one

[tex]-8.6, -5.0, -1.4, 2.2, 5.8,......\\-5-(-8.6)=3.6\\-1.4-(-5)=3.6\\2.2+1.4=3.6\\[/tex]

Its arithmetic because common difference is same 3.6

2, –2.2, 2.42, –2.662, 2.9282, …

-2.2-2=-4.2

2.42+2.2=6.62

Its not arithmetic

5, 1, –3, –7, –11, …

1-5=-4

-3-1=-4

-7+3=-4

-11+7=-3

Common difference is -4. So it Arithmetic

–3, 3, 9, 15, 21, …

3+3=6

9-3=6

15-9=6

Its Arithmetic

–6.2, –3.1, –1.55, –0.775, –0.3875, …

-3.1+6.2=3.1

-1.55+3.1=1.55

Its not Arithmetic

So, options I, III and IV  are Arithmetic sequences.

Answer:

Toby Vail wis taxed for $456

Step-by-step explanation:

First, we make the deductions:

gross pay 18,200 - 1,500 deductions = 16,700 taxable income

Now, we make the tax-calculations:

first $3,000 x 0.015 =       $ 45

above:

(16,700 - 3,000) x 0.03 =  $411

Total tax levied from the State:  $45 + $411 = $456

Notice how the tax is calcualte in brackets to solve for the different taxation rate at different income levels.

Answer:

10

Step-by-step explanation:

If there is a direct relation between two variables x and y then it can be represented as

y = kx ,

where y is dependent variable

x is  independent variable

k is constant of variation

_____________________________

First condition

y = 400

x = r

using y = kx then relationship will be

400 = kr

finding k here

k = 400/r

Second condition

y = r

x = 4

using y = kx then relationship will be

r = 4k

finding k

k = r/4

since  in both condition equation is same

thus, value of k will also be same

thus,

400/r = r/4

=> 400*4 = r*r

=> 1600 = r^2

[tex]\sqrt{r^{2} } = \sqrt{1600} \\r = 40[/tex]

Thus, 40 is the value of r

k = r/4 = 40/4 = 10

Thus, constant of variation is 10 which is correct choice.

To cross validate

k = 400/r = 400/40 = 10

Answer:

40

Step-by-step explanation:

[tex]\frac{r}{400}[/tex] = [tex]\frac{4}{r}[/tex]

cross multiply - 400*4 = 1600 and r*r = r^2

square both - √1600 = 40

✦ Sometimes in math simplify could mean just solve and get the smallest version of that number. That's what it means in this case. So the simplified version would be 3.2.
