:- Six more than one third of a number is three. Find the number.

:-

Let the number be x

One third of a number = x =

Six more than one third of a number = + 6

Their sum = 3

Accoeding to the question,

+ 6 = 3

Multiplying both sides by 3 we get,

x + 18 = 9

Moving constant to the right, we get,

x = 9 - 18

By calculation, we get,

x = -9

∴ The number is -9

Verification :-

+ 6 = 3

=> + 6 = 3

=> -3 + 6 = 3

=> 3 = 3

LHS = RHS ✔✔

∴ The number is -9

x =14

Answer:

$m\angle ABC = 51°$

Step-by-step explanation:

11. By inscribed angle theorem:

$83°=\frac{1}{2} \times (9x+40)°\\\\83°\times 2 = (9x+40)°\\166°= (9x+40)°\\166 = 9x + 40\\166 - 40 = 9x\\126 = 9x\\\\x = \frac{126}{9}\\\\\huge \red {\boxed {x = 14}}$

12. Again by inscribed angle theorem:

$(5x+11)°=\frac{1}{2} \times (16x-26)°\\\\2\times (5x+11)°= (16x-26)°\\(10x+22)°= (16x-26)°\\10x + 22 = 16x - 26\\22+26 = 16x - 10x\\48= 6x\\\\x = \frac{48}{6}\\\\\huge \purple{\boxed {x = 8}}\\m\angle ABC = (5x+11)°\\m\angle ABC = (5\times 8+11)°\\m\angle ABC = (40+11)°\\\huge \orange{\boxed {m\angle ABC = 51°}} \\$

Each morning a gardener uses 25 gallons of water from a barrel. Each afternoon, she adds 15 gallons of water to the barrel. By h

mr_godi [17]

Given :

Each morning a gardener uses 25 gallons of water from a barrel.

Each afternoon, she adds 15 gallons of water to the barrel.

To Find :

By how much has the volume of water in the barrel changed after 5 days.

Solution :

Amount of of water used from the barrel per day is :

A = 25 - 15 gallons

A = 10 gallons

Now, volume of water in the barrel changed after 5 days is :

V = A × 5 gallons

V = 10 × 5 gallons

V = 50 gallons

Therefore, volume of water in barrel is changed by 50 gallons.

A linear relationship with a slope of 2 and a<br> y-intercept of 3

qwelly [4]

Answer:

The linear relationship is represented by y = 2x + 3.

Step-by-step explanation:

We are given a y-intercept of an equation as well as a slope:

slope = 2
y-intercept = 3

We can use this information and substitute it into the slope-intercept form equation to get our linear relationship:

y = mx + b

In this formula, m is our slope and b is our y-intercept.

Therefore:

m = 2
b = 3

Finally, let us substitute these into the equation:

$y = 2x + 3$

This is our final equation.

Answer:

See below

Step-by-step explanation:

Which is the closest to 6

$\sqrt{34}$

$\sqrt{39\\$

$\sqrt{35$

or $\sqrt{38}$

So, find the square root of each ( I suggest using a calculator)

$\sqrt{34} = 5.83\\\sqrt{39} = 6.24\\\sqrt{35} = 5.91 \\\sqrt{38} = 6.16$

Which is closest? Let's see.

6 - 5.83 = 0.17

6.24 - 6 = 0.24

6 - 5.91 = 0.09

6.16 - 6 = 0.16

Find the smallest #

0.09 is the smallest, so 5.91 is the closest. Square the #, we get $\sqrt{35}$

Hope this helps! =D
