Answer: ( . is another way to write a multiplication sign.

X = the amount of pounds each rice bag has.)

7 + 4 . X = 64

Not sure if this is needed but X = 14.25 so if there is a follow up question that asks how many pounds are in each bag of rice the answer would be 14.25.

If you can not use X in the equation another way of writing it would be 7 + 4 . 14.25 = 64

I am not sure which equation your teacher would want because that all depends on the teacher and if there are any further details on the question. So if somewhere on the question it said you have to use a variable you would use the equation with the variable.

Step-by-step explanation:

1.  The question claims that the total of all of the pounds of rice and bean bas equals a total of 64 so that would be the answer to the equation.

2. You now need to make an equation that represents the situation by setting up your equation like this: 7 + 4 . X = 64

How to find X and have an equation with an already solved X.

1  We know that in total each bag has 64 pounds so that means we have to subtract 7 from 64. The difference is 57.

2. We now need to divide 57 by 4 because the rest of the bags have an identical amount of pounds so your answer should be 14.25.

3. Your equation should be set up like this: 7 + 4 . 14.25 = 64

Answer:

Around 72.8 inches

Step-by-step explanation:

We are given the infomation that Chris is 185 centimeters tall.

There are 2.54 centimeters in an inch.

185/2.54 = 72.8346 ≈ 72.8

Chris should be around 72.8 inches.

Hope this helps.

Chris should be around 72.8 inches tall.

Here, we have,

given that,

Scott is 72 inches tall and Chris is 185 centimeters tall

We are given the information that Chris is 185 centimeters tall.

now, we know that,

There are 2.54 centimeters in an inch.

Since 1 inch = 2.54 centimeters

all we need to do is to divide 185 by 2.54

i.e. 185/2.54 = 72.8346 ≈ 72.8

The answer will be 72.8.

Chris should be around 72.8 inches.

And so on.

Answer:

1. d ≈ 19

2. a ≈ 39.00°

3. x ≈ 37°

Step-by-step explanation:

1) Using sine to find d, recall that sine = opposite side/hypotenuse. So:

[tex]sin(39) = \frac{d}{30}[/tex]

Cross multiply:

d = 30 (sin(39))

d ≈ 19

2) To find the measure of the angle, we can use sine because we have the opposite side and hypotenuse measures. So:

[tex]sin(a) = \frac{18.88}{30}[/tex]

Using the inverse of sine:

[tex]a = sin-1(\frac{18.88}{30})[/tex]

Input into calculator:

a ≈ 39.00°

3) To find the measure of the angle, we can use tangent because we have the opposite side and adjacent side measures. So:

[tex]tan(x) = \frac{300}{400}[/tex]

Using inverse of tangent:

[tex]x = tan-1 (\frac{300}{400})[/tex]

Input into calculator:

x ≈ 37°

Equation: 0.2*20+x*80=1.36*100

there fore the answer is 33/20

The cost of 1 lb of sugar candies is $1.65.

Given to us

Total cost of candy mix = weight of candy mix [tex]\times[/tex]  Cost of candy mix

                                       [tex]= 100\ lb\times \$1.36[/tex]

Total cost of Jelly beans = weight of Jelly beans [tex]\times[/tex]  Cost of Jelly beans

                                       [tex]= 20\ lb\times \$0.20[/tex]

weight of Sugar candies = weight of candy mix - weight of jelly bean

                                         [tex]=100\ lb - 20\ lb\\= 80\ lb[/tex]

Total cost of candy mix = Total cost of jelly beans + total cost of sugar candies

[tex]100\ lb \times \$1.36 = (20\ lb \times \$0.20) + (80\ lb \times x)\\136 = 4 + (80x)\\136-4 = 80x\\132 = 80x\\x = \dfrac{132}{80}\\x =1.65[/tex]

Hence, the cost of 1 lb of sugar candies is $1.65.

Look at the graph i sent you.

Graph of : y = 3sqrt(x+1) - 2

Answer:

[tex]y=10x+15[/tex]

Step-by-step explanation:

We want the equation of a line with a slope of 10 and passes through (-4, -25).

We can use the point-slope form given by:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

So, we will substitute 10 for m and (-4, -25) for (x₁, y₁):

[tex]\displaystyle y-(-25)=10(x-(-4))[/tex]

Simplify:

[tex]y+25=10(x+4)[/tex]

Distribute:

[tex]y+25=10x+40[/tex]

Subtract 25 from both sides:

[tex]y=10x+15[/tex]

And we have our equation.

=========================================================

Work Shown:

The given equation y = (1/5)x+4 is in the form y = mx+b with m = 1/5 as the slope.

Apply the negative reciprocal to this slope to go from 1/5 to -5/1 or -5.

The original slope is 1/5 and the perpendicular slope is -5. Note the two slopes multiply to -1. This applies to any pair of perpendicular lines as long as neither line is vertical.

---------

We'll use m = -5 as the slope and (x,y) = (5,-4) to find the y intercept

y = mx+b

-4 = -5*5+b

-4 = -25+b

-4+25 = b

21 = b

b = 21

The y intercept of the perpendicular line is b = 21

With m = -5 and b = 21, we go from y = mx+b to y = -5x+21 which is the equation of the perpendicular line.

The sequence of dots for each of the steps is: {0, 2, 4, 6, ...}

Each time we're increasing by 2 dots. This suggests a linear pattern

The linear equation that models this is y = 2x. The slope is 2 and the y intercept is 0. The slope of 2 tells us how much the dots grow each time, while the y intercept tells us our starting point.

Given:

The system of equations is

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

[tex]2y-4x=?[/tex]

To find:

The missing value for which the given system of equations have infinitely many solutions.

Solution:

Let the missing value be k.

We have,

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

[tex]2y-4x=k[/tex]

Taking all the terms on the left side, the given equations can be rewritten as

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

[tex]-4x+2y-k=0[/tex]

The system of equations [tex]a_1x+b_1y+c_1=0[/tex] and [tex]a_2x+b_2y+c_2=0[/tex] have infinitely many solutions if

[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}[/tex]

We have,

[tex]a_1=-2,b_1=1,c_1=5[/tex]

[tex]a_2=-4,b_2=2,c_2=-k[/tex]

Now,

[tex]\dfrac{-2}{-4}=\dfrac{1}{2}=\dfrac{5}{-k}[/tex]

[tex]\dfrac{1}{2}=\dfrac{1}{2}=\dfrac{5}{-k}[/tex]

[tex]\dfrac{1}{2}=\dfrac{5}{-k}[/tex]

On cross multiplication, we get

[tex]-k=10[/tex]

[tex]k=-10[/tex]

Therefore, the missing value is -10.

Answer:

y=2/3x-4/3

Step-by-step explanation:

1- reword the statement to equal y

3y=-4+2x

2-Bring the 3 over

y=2/3x-4/3

Answer:

3(7-2y)=9

Because there is no symbol between the 3 and the "(" we can tell that it wants you to multiply.

With the distributive property you must distribute the 3 within (7-2y)

To that you would multiply 7 by 3, and multiply -2y by 3. This would get you:

21-6y=9

To get y you must isolate it, the first step to isolate it is remove the number with no "y" next to it. Which is "21" Also for further problems your way, You should add/subtract/divide/multiple the number that does not have the same or even a variable as the variable you are trying to find to the other side.

In this case it would be subtracting 21 from the left side and subtracting it to the right side which would give us: 6y=-12

(Because there was already a number with no variable: "9" you will subtract 21 from 9 which is why you get -12).

Next you will further isolate the y by removing the -6. "-6y" means -6 multiplied by y. So you will divide -6 from the left side AND the right side.

-6y ÷ -6 = y ; -12 ÷ -6 = 2

y=2

More tips: When you are moving something to the other side always do the opposite to remove it from one side and move it to the other. Example: -12 + y = 5

You want to move the -12 to the right side. So you need to remove "-12" from the left side by ADDING 12 because -12 + 12 = 0.

Now you simply add it to the right.

Another example: 4y = 8

Because 4y is multiplication (4 times y) you must divide it from each side to isolate the y! : y=2

If you divide a number from the left side, you must also divide it from the right side. If you add a number on the left side, you must also add it on the right side. Same goes for subtraction and multiplication. Think like that!
