Answer:

Well I think the answe is

1. (1,3) (1,7)

2. (2,-3) (6,-5)

The correct value of x is 29.14 or x divided by 6/7 = 3 and 2/5 is 29.14.

Here:

X divided by 6/7 = 3 and 2/5.

x ÷ 6/7 = 3 and 2/5,

To convert into fraction.

x/1 ÷ 6/7, reciprocal of 6/7 is 7/6.

x/1 × 7/6 = 7 x/6,

3 and 2/5 = 17/5.

(7 x/6) = 17/5

x = (6  × 17)/7  × 5

x = 29.19

Therefore X divided by 6/7 = 3 and 2/5 or the value of x is 29.19.

Explanation:

Each equation asks for x . So let's solve it in a way so that at the end remains x = ,then the rest equation.

So first one,

1. a(x+b)=c

ax + ab = c

ax = c - ab

x = (c - ab ) / a

Now we can write that in two ways:

i. We already got the answer for the 2nd blank which is c - ab / a

ii. If we rearrange it so that there is a minus sign, it would be like: c/a  - b

Try solving the rest 3 by your self to make sure you understood them. Then scroll down to match the answers.

2. 8(x + a) = b

8x + 8a = b

8x = b - 8a

x = (b-8a)/ 8

First blank for 2nd equation: x = b/8  - a

Second blank: x = b - 8a  /  8

3. a(x - 9) = b

ax - 9a = b

ax = b + 9a

x = (b + 9a) / a

First blank for 3rd equation: x = b/a + 9

Second blank: x = b+9a  /  a

4. c(2 + x ) = 7

2c + cx = 7

cx = 7 - 2c

x = (7 - 2c) / c

First blank for 4th equation: x = 7/c  - 2

Second blank: x = 7 - 2c  / c

Answer:

[tex]33\frac{1}{3}[/tex] ft

Step-by-step explanation:

Think about the ratio of shadow to actual height.

First, make a ratio table demonstrating the scale factor of the shadow to the height of the object:

height   :   shadow

6 ft        :    4.5 ft

To get rid of the decimal, multiply by 10 on both sides:

60 ft      :    45 ft

In order to get the shadow to 25 ft, multiply both sides by 25/45, which simplifies to 5/9:

height   :   shadow

6 ft        :    4.5 ft

60 ft      :    45 ft

*(5/9)     :    *(5/9)

33 1/3 ft :    25 ft

The answer is the height corresponding to the shadow length 25 ft in the table, in this case, [tex]33\frac{1}{3}[/tex].

Answer:

Sven must get an 83 to reach his goal.

Step-by-step explanation:

Find the mean of the 4 numbers by adding all of them and dividing by the how many numbers, and his average grade is 74.25. Find the number that when added to the others gets a median of 76, and the answer is 83.

Let a, b, c, d be coefficients for the balanced reaction:

a HC₂H₃O₂ + b KNO₂   →   c KC₂H₃O₂ + d HNO₂

Count the elements among the reactants and products:

H: 4a = 3c + d

C: 2a = 2c

O: 2a + 2b = 2c + 2d

K: b = c

N: b = d

Suppose we let b = 1. Then both c = 1 and d = 1, and in the O equation we have

2a + 2 = 2 + 2   ⇒   2a = 2   ⇒   a = 1

(Note that the equations for H and C also hold up.)

So the balanced reaction is simply

1 HC₂H₃O₂ + 1 KNO₂   →   1 KC₂H₃O₂ + 1 HNO₂

Answer:

Let selling price of three-piece suit = x. Applying 7% sales tax, total amount paid = x + xx7 - $152.79. 100 207 100 ०१ This is the $ 152.79 os, x- $142.7943 price after marked down of 40%, let the regular price of three-piece suit be = y. Therefore y [ 3 - 4m] $342.1943 1 - - $237.99 Regular price of 1 piece suit $ 237.99

The regular selling price of the suit will be equal to $209.816

The cost at which any product is sold is called as the selling price of the product.

Given that:-

40% discount on the original price.

The selling price = $152.79

Sales tax = 7%

So the original selling price of the product without discount will be equal to:-

= 157.79   x   0.07  =  $11.04

So the cost without tax will be:-

=  157.79  -   11.09  =  146.7

The original selling price without discount will be:-

= 157.79  x  0.40  =  63.116

So the price will be

=   146.7   +    63.116    =   $209.816

Hence the regular selling price of the suit will be equal to $209.816
