Answer:

70mph = 112.6538kph

Thats a whole number? It can't be rounded to the tenth percent if it doesn't even have a decimal point

But if you mean as a number and not a percent, it would be 9.9

Substitute y = 2x - 15 to the second equation:

4x + 3(2x - 15) = -5      use distributive property

4x + (3)(2x) + (3)(-15) = -5

4x + 6x - 45 = -5       add 45 to both sides

10x = 40      divide both sides by 10

x = 4

Substitute the value of x to the equation y = 2x - 15:

y = 2(4) - 15 = 8 - 15 = -7

and

[tex]y= \frac{-9}{62}[/tex]e have

EXPLANATION

[tex]17x-3y=4---(1)[/tex]

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

Let us make y the subject and call it equation (2)

[tex]2x=1+4y[/tex]

[tex]x=\frac{1}{2}+2y--(2)[/tex]

We put equation (2) in to equation (1)

[tex]17(\frac{1}{2}+2y)-3y=4[/tex]

[tex]\frac{17}{2}+34y-3y=4[/tex]

[tex]34y-3y=4- \frac{17}{2} [/tex]

Simplify to get,

[tex]31y= \frac{8-17}{2} [/tex]

[tex]31y= \frac{-9}{2} [/tex]

Divide both sides by 31,

[tex]y= \frac{-9}{2} \div 31[/tex]

[tex]y= \frac{-9}{2} \times \frac{1}{31}[/tex]

[tex]y= \frac{-9}{62}[/tex]

We put this value in to equation (2) to get,

[tex]x=\frac{1}{2}+2\times -\frac{9}{62}[/tex]

[tex]x=\frac{1}{2} -\frac{18}{62}[/tex]

We collect LCM to obtain,

[tex]x=\frac{31-18}{62}[/tex]

[tex]x=\frac{13}{62}[/tex]

Look at the picture.

you do 4 3/4 times 5= 95/4-23 3/4

Total amount of money spent: 305.42

Money spent the first month: 213.20

Money spent on the second month: ??

Subtract 305.42 - 213.20= Amount of money spent the second month

Answer: 92.23

In Mathematics, the solution to this subtraction problem is to subtract the amount spent in the first month, $213.20, from the total amount spent on groceries, $305.43. The result is $92.23, the amount spent in the second month.

This appears to be a simple subtraction problem within the domain of Mathematics. If the total amount spent on groceries is $305.43 and she spent $213.20 in the first month, then to find out how much she spent in the second month, you need to subtract the amount spent in the first month from the total amount.

To solve this, you do the following calculation: $305.43 - $213.20 = $92.23.

Therefore, she spent $92.23 on groceries in the second month.

The speed of the boat in still water is 8 miles per hour.

To find the speed of the boat in still water, we can use the formula:

Speed of the boat in still water = (speed downstream + speed upstream) / 2

Given that it takes the same amount of time for the boat to travel 36 miles downstream and 12 miles upstream, we can set up the following equation:

36 / (v + 4) = 12 / (v - 4)

Where v is the speed of the boat in still water. Cross multiplying and solving the equation, we get:

36(v - 4) = 12(v + 4)

36v - 144 = 12v + 48

24v = 192

v = 8

Therefore, the speed of the boat in still water is 8 miles per hour.

Let denote the two numbers with X and Y. n represent one number

Y=X + 3 1/3

The sum of the two numbers is: X+Y=X + X + 3 1/3

The triple sum is: 3(X + X + 3 1/3)

3(X + X + 3 1/3) = 133

3X + 3X + 10 = 133            

6X + 10 = 133                    

6X = 123                            

X = 12 1/2                  , Y= X+ 3 1/3 =  12 1/2 = 3 1/3 is the largest number

Answer:

[tex]23\frac{5}{6}[/tex]

Step-by-step explanation:

Let x be the smaller number,

Thus, according to the question,

Second number or larger number = [tex]x+ 3\frac{1}{3}[/tex]

Now, sum of these number = [tex]x+x+ 3\frac{1}{3}=2x+\frac{10}{3}[/tex]

Again according to the question,

[tex]3\times ( 2x + \frac{10}{3})= 133[/tex]

[tex]6x + 10 = 133[/tex]

[tex]6x = 123[/tex]

[tex]\implies x = \frac{123}{6}[/tex]

Thus, the larger number = [tex]\frac{123}{6}+3\frac{1}{3}=\frac{123}{6}+\frac{10}{3}=\frac{123+20}{6}=\frac{143}{6}=23\frac{5}{6}[/tex]

Answer:

Volume of Gold = 0.4 cubic feet.

Step-by-step explanation:

First we have to make sure the units are same as the units the answer is required in.

Answer should be given in cubic feet.

Density is given in pounds per cubic foot. And Mass is given in pounds. So units are in order. Therefore, we can go ahead with the calculation.

The Density of Gold = [Mass of Gold/Volume of Gold]

By substituting values,

[tex]1204[/tex] ponds per cubic foot = [[tex]481.6[/tex] pounds / Volume of gold]

Making Volume of God the subject of the equation,

Volume of Gold = [[tex]481.6[/tex] pounds / tex]1204[/tex] ponds per cubic foot ]

Volume of Gold = 0.4 cubic feet.

To write an expression in function notation, you must solve it for the dependent variable.

Assuming that you want the expression to be written in the form [tex] y = f(x) [/tex] (i.e., assuming that x is the independent variable), we have to solve the expression for y, which means that we want y to remain alone on the left hand side, and move everything else to the right hand side.

So, first of all, we can add 9x to both sides to get

[tex] 3y = 9x+24 [/tex]

Finally, we divide both sides by 3:

[tex] y = 3x + 8 [/tex]

It's an identity equation.

Hey there!!  

Given equation :

... 2t + 8 > -4 ( t + 1 )

Using the distributive property :

... 2t + 8 > -4t - 4

Adding 4t on both sides :

... 6t + 8 > - 4

Subtracting 8 on both sides :

... 6t > - 12

Dividing by 6 on both sides :

... t > -2

Hence, the number in the blank is -2.

When a number is raised to the power of 2, it is squared. This means the number is multiplied by itself once.

When a number is raised to the power of 2, it is squared. Squaring a number means multiplying it by itself. For example, if you have the number 4 and you square it (raise it to the power of 2), you would multiply 4 by 4, which equals 16. Therefore, 4 squared (or 4 to the power of 2) equals 16.
