x to the second power plus 4equals 40 solve for x

Answer:

x = 30

Step-by-step explanation:

x/5 + 1 = 7

subtract 1 from each side

x/5 + 1-1 = 7-1

x/5 = 6

Multiply each side by 5

x/5 *5 = 6*5

x = 30

Answer:

C.

Step-by-step explanation:

Essentially it's 1*0 since anything to the power of 0 is 1 and 0 to the power of anything is still 0.

Step-by-step explanation:

To solve one step equations you have to do the opposite of whatever operation is being performed on the variable so you have to get the variable by itself

The most important thing to remember is that whatever you do to one side of the equation, you have to do the same thing to the other side.

Answer:

π (Pi) is a mathematical constant.

Step-by-step explanation:

The digit π is a mathematical constant. It is interpreted as the ratio of a circle's perimeter to its diameter, and it also has various equivalent definitions. It appears in many formulas in all areas of mathematics and physics. It is roughly identical to 3.14159.

Answer:

m = 68 - c ; 35

Step-by-step explanation:

Given the following :

Number of blocks Tegan needs to make = 68

Number of blocks completed = c

Number of blocks left to make = m

Therefore, the number of blocks 'm' left to make is given by the equation :

(Total number of blocks needed - number of blocks completed) = number of blocks left to make

(68 - c) = m

Equation : m = 68 - c

If completed blocks 'c' = 33 ; number of blocks needed to complete the igloo :

From m = 68 - c

m = 68 - 33

m = 35

Answer:

Equation: m = 68 - c   Answer: 35

Step-by-step explanation:

Tegan needs 68 more blocks for her igloo. The number of blocks she still needs to make depends on c, the number of blocks she completes.

To find the number of blocks she still needs to make, m, we can use the equation m = 68 - c

To find the number of blocks Tegan still needs to make if she completes 33 blocks we can substitute 33 into the equation for c.

m = 68 - c

m = 68 - 33

m = 35

The equation is m = 68 - c

Tegan still needs to make 35 blocks to finish the igloo.

Answer: Nope.

Explanation: In order to combine like-terms, they must all have the same variable. In 3x + 13y + 10, none of them have the same variable, so therefore cannot be combined.

Answer:

A ≈ 47.759 cm²

Step-by-step explanation:

A = πr²

A = (3.14)(3.9)²

A = (3.14)(15.21)

A ≈ 47.759 cm²

Answer:

Step-by-step explanation:

A proportion can be written a number of ways. Here, we're asked for a specific ratio. Ratios are generally written using a colon (:) or a division symbol (/ or ÷). Here, the cable bill must be computed from the amounts of the other portions of the bill. That computation lends itself to being written in different ways. The point of the exercise is unclear, so the desired 'three different ways' are also unclear.

__

If we assume that the cable TV portion of the bill is separable from the package, it can be written as ...

  cable bill = $90 -35 -14 = $55 -14 = $41

So, the ratio of internet to cable bills can be written as any of ...

  internet : cable = 35 : (90 -35 -14)

  internet : cable = 35 : (55 -14)

  internet : cable = 35 : 41

  internet / cable = 35 / (90 -35 -14)

  internet / cable = 35 / (55 -14)

  internet / cable = 35 / 41

__

Of course, the computation of the cable bill can be accomplished other ways, so that expression could be any of

  cable bill = 90 -49 = 76 -35

Then you could have ...

  internet : cable = 35 : (90 -49)

  internet / cable = 35 / (76 -35)

Answer:

x = 2

Step-by-step explanation:

The length of bottle G in cm is 5x + 12

The length of bottle H in cm is 3x + 16

The bottles are of equal length, so set them equal to each other to solve for x:

5x + 12 = 3x + 16

2x = 4

x = 2

Answer:

tbh i would say 1/8 in exact form

Answer:

x = 6

Step-by-step explanation:

[tex]\frac{9+x}{3x} = \frac{5}{6}[/tex]

6(9+x) = 5(3x)

6*9 + 6*x = 5*3x

54 + 6x = 15x

54 = 15x - 6x

54 = 9x

x = 54/9

x = 6

check:

(9+6)/(3*6) = 5/6

15/18 = 5/6

Answer:

∠abc=34°

∠dbc= 44°

Step-by-step explanation:

(5x+4)+(5x-6)=78

10x-2=78

10x=78+2

10x=80

x=8

put x in each equation

∠abc= 5x8-6

        40-6

        34°

78-34= ∠dbc

∠dbc= 44°

Answer:

7.28

Step-by-step explanation:

It’s the hypotenuse of a right triangle, so we can use Pythagorean’s Theorem.

2²+7²=C²

4+49=c²

53=c²

c=7.28

Answer:

7.28 to the nearest hundredth.

Step-by-step explanation:

A is (-5, -4) and B is (-3,3)

The distance AB = √ [(-5 - (-3)^2 + (3 - (-4)^2]

= √(4 + 49)

=√53

= 7.2801

Step-by-step explanation:

first obvious thing is the line is positive

it goes up 3 over 2

so its 3/2

positive = 3/2

Step-by-step explanation:

To solve this problem, let's set up our equation to solve for x (time to travel 13 miles).

[tex]\frac{65}{1} =\frac{13}{x}[/tex]

We use this equation to find x. To solve, we divide 13 by 65 to get our answer.

13 ÷ 65 = 0.2

Answer:

  2√41 ≈ 12.81 units

Step-by-step explanation:

The distance between two points is conveniently found using the distance formula:

  d = √((x2 -x2)^2 +(y2 -y1)^2)

  d = √((-3-5)^2 +(8-(-2))^2) = √(64 +100) = 2√41 ≈ 12.81 . . . units

Answer:

The last table with x and y values:

x       y

40    60

160   15

200   0

is the correct table

Step-by-step explanation:

Notice that the x-value 40 appears in all four tables, so let's use it according to the piece-wise function definition to decide which table can be the true one.

Notice that from the function's description, when x = 40 the function that should be used is (its domain includes 40 according to: [tex]40\leq x\leq 200[/tex] ) : [tex]f(x)=-\frac{3}{8} x+75[/tex],

which therefore gives : [tex]f(40)=-\frac{3}{8} (40)+75= -15+75=60[/tex]

therefore, we know that the only table that shows a y-value of 60 associated with x=40 is the last table. We should check that the other two pairs are also correct before deciding for it:

Is f(160) = 15 , and is f(200) = 0 according to the function's definition?

Let;s calculate f(160) (for which we need to use again the second function given which is valid for x values such that: [tex]40\leq x\leq 200[/tex]

[tex]f(160)=-\frac{3}{8} (160)+75= -60+75=15[/tex]

so, this pair is also correct.

Now the last check (for x = 200):

[tex]f(200)=-\frac{3}{8} (200)+75= -75+75=0[/tex]

which also checks with the values in the given table.

Answer:

x=1

Step-by-step explanation:

-2x+4=1-4x-3

↦-2x+4x=1-3+4

↦2x=2

↦x=2/2

↦x=1

.°. x = 1

Answer:

[tex] - 2x + 4 = 1 - 4x - 3[/tex]

Firstly take all numbers with variable to L.H.S

and Take all numbers to R.H.S

[tex] - 2x - 4x = 1 - 3 - 4[/tex]

Now solve the equation we get our answer

[tex]-6x = -6[/tex]

Take -6 to the R.H.S and divide -6 by -6

[tex]x = 1[/tex]

Answer: b. 51 - 3

Step-by-step explanation:

Given, Easha has 3 less than 5 times the number of quarters (I)  that Isabelle has.

Here I is the number of quarters that Isabelle has.

Then, as per given,

Number of quarters Easha has = 5 ( number of quarters that Isabelle has) -3

= 5I-3

Hence, the  expression shows the number of quarters Easha has is "5I-3"

So the correct option is b.

Step-by-step explanation:

Simplify the following:

5 - 2×9 + 9^2/3

Hint: | Evaluate 9^2.

9^2 = 81:

5 - 2×9 + 81/3

Hint: | Reduce 81/3 to lowest terms. Start by finding the GCD of 81 and 3.

The gcd of 81 and 3 is 3, so 81/3 = (3×27)/(3×1) = 3/3×27 = 27:

5 - 2×9 + 27

Hint: | Multiply -2 and 9 together.

-2×9 = -18:
