What is the value of a + bc when a = 7, b = 4, and c = 2 ?

Answer:

"in an average of" / "approximately"

Step-by-step explanation:

these clue words do not hold any definite value. therefore, it can be used for estimating.

Answer:

4/8 or 1/2

Step-by-step explanation:

7/8-3/8= 4/8 or 1/2 because 4 is half of 8

Answer: x = 2.

Step-by-step explanation:

By an online search, i found that the question is:

"Given that x satisfies the inequality 20*x > 33,  find the smallest value of x if x is a prime number."

To find the smallest value of x we need to input different possible values of x (where we have the condition that x must be a prime number) and see which one is the first one that makes the inequality true.

The prime numbers are:

2, 3, 5, ....

Let's start with the smaller one, x = 2

So we input it in the inequality and get:

20*2 > 33

40 > 33

this is true.

Then we can have x = 2, which is the smaller prime number that satisfies the inequality.

Answer:

Bob=19.60

Elsa=25.60

Chang=58.80

Step-by-step explanation:

(E)lsa + (C)hang + (B)ob=104

C=3B

E=B+6

substitute

(B+6)+3B+B=104

5B+6=104

5B=98

5B/5=98/5

B=19.60

E=19.60+6=25.60

C=3(19.60)=58.80

Answer:

28.86

Step-by-step explanation:

According to the scenario, computation of given data are as follows,

Exponential smoothing a = 0.1

we can calculate forecast for each week by using following formula,

Forecast for week = Forecast of last week + a × ( actual calls of last week - forecast of last week)

By using this method, forecast for all week are as follows

Week            Actual calls                Forecast                     Calculation

1                        28                               28

2                       34                               28                    [28 + 0.1 × ( 28 - 28)]

3                       38                               28.60              [28 + 0.1 × ( 34 - 28)]

4                       27                               29.54              [28.6 + 0.1 × ( 38 - 28.6)]

5                       25                              29.29               [29.54 + 0.1 × ( 29 - 29.54)]

6.                                                         28.86             [29.29 + 0.1 × ( 25 - 29.29)]

Answer:

3√10

Step-by-step explanation:

Answer:

We conclude that:

[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]

The solution graph on the number line is also attached.

Step-by-step explanation:

Given the inequality

[tex]-8x\:\le 32[/tex]

Solving the inequality

[tex]-8x\:\le 32[/tex]

Multiply both sides by -1 (reverse the inequality)

[tex]\left(-8x\right)\left(-1\right)\ge \:32\left(-1\right)[/tex]

Simplify

[tex]8x\ge \:-32[/tex]

Divide both sides by 8

[tex]\frac{8x}{8}\ge \frac{-32}{8}[/tex]

Simplify

[tex]x\ge \:-4[/tex]

Therefore, we conclude that:

[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]

The solution graph on the number line is also attached.

Answer:

[tex]f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 2x-2& \quad x \geq 5/2 \\ -2x+8 & \quad x < 5/2 \end{array} \right.[/tex]

Step-by-step explanation:

We are given the function:

[tex]f(x)=3+|2x-5|[/tex]

Remember that by the definition of absolute value:

[tex]\displaystyle |x|= \left\{ \begin{array}{ll} x & \quad x \geq 0 \\ - x & \quad x < 0 \end{array} \right.[/tex]

Our absolute value is:

[tex]|2x-5|[/tex]

First, we will find when it becomes 0. Set the equation equal to 0:

[tex]2x-5=0[/tex]

Solve for x:

[tex]x=5/2[/tex]

So, we can see that for all values greater than x = 5/2, 2x - 5 is positive.

For all values less than x = 5/2, 2x - 5 is negative.

Therefore (the positive case go above, and the negative case go below):

[tex]|2x-5|= \left\{ \begin{array}{ll} 2x-5 & \quad x \geq 5/2 \\ -(2x-5) & \quad x < 5/2 \end{array} \right.[/tex]

Finally, we can add a three:

[tex]f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 3+(2x-5) & \quad x \geq 5/2 \\ 3+(-(2x-5)) & \quad x < 5/2 \end{array} \right.[/tex]

Simplify if desired:

[tex]f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 2x-2& \quad x \geq 5/2 \\ -2x+8 & \quad x < 5/2 \end{array} \right.[/tex]

Answer:

I guess the answer is 4.4 cm or 22/5 cm

Step-by-step explanation:

AREA= 15cm^2

Let the Breadth be x

Length= 4x-7

Area = l×b

15 = 4x-7×x

15+7=4x+x

22=5x

22÷5=x

4.4=x

Therefore, Breadth= 4.4cm Length= 10.6cm

Answer:

The slope is 1/2

Step-by-step explanation:

let both unknowns be x and y

x = 5y. ......(1)

x + y = 90. ......(2)

sub eqn (1) into eqn (2)

5y + y = 90

6y = 90

y = 90/6

= 15

sub y = 15 to eqn (1)

x = 5y

x = 5 × 15

Amount fudge he needs = 23/24 kg

Step-by-step explanation:

Given:

Total fudge wants = 1[tex]\frac{1}{2}[/tex] = 3/2 kg

His sister gave = 1/6 kg

He make = 3/8 kg

Find:

Amount fudge he needs

Computation:

Amount fudge he needs = Total fudge wants - His sister gave - He make

Amount fudge he needs = 3/2 - 1/6 - 3/8

Amount fudge he needs = 23/24 kg

A = 3

B = 8

C = 2

D = 5

Step-by-step explanation:

The language is solved and the four digit code is given by

A = 3

B = 8

C = 2

D = 5

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

2 + 1 = A

On simplifying the equation , we get

A = 3

Now , 3 + 5 = B

B = 8

And , D + 3 = 8

Subtracting 3 on both sides , we get

D = 5

And , 3 + C = 5

Subtracting 3 on both sides , we get

C = 2

Hence , the four digit code is A = 3 , B = 8 , C = 2 , D = 5
