Three fourths of a number p less subtracted by 2 is 5 sixths of a number r plus 5
goldenfox [79]
Three fourths of a number p less subtracted by 2 is 5 sixths of a number r plus 5

3/4 of  p subtracted by 2 is 5/6 of a r plus 5

3/4 of p - 2 is 5/6 of r + 5

\frac{3}{4} p-2= \frac{5}{6} r+5   <--- answer?

\frac{3}{4} p= \frac{5}{6} r+7    

\frac{3p}{4} = \frac{5r}{6} +7

\frac{3p}{4}* \frac{6}{5r}  = 7

\frac{18p}{20r} = 7

\frac{9p}{10r} = 7

\frac{p}{r} = 7* \frac{10}{9}

\frac{p}{r} = \frac{70}{9}   <-- answer?

Hope this helps

thomas buys a cardboard sheet that is 8 by 12 inches. let x be the side lenghth of each cut out. create an equation for the volu
nikitadnepr [17]
Hi there! 

Lets dive into the problem, starting with the equation for volume; length x width x height.

If it's 8 x 12 inches, That means the height is 8 and the length is 12. The side, or width, would be x.

The equation should be 8 times 12 times x, or (8)(12)(x).

Which equation should be used to calculate the 43rd partial sum for the arithmetic sequence.
MariettaO [177]

Answer: First Option : Sₙ= n/2(a₁ + aₙ)

Step-by-step explanation:

The nth partial sum of an arithmetic sequence or the sum of the first n terms of the arithmetic series can be defined as the sum of a finite number of term in an arithmetic sequence.

It is calculated using the formula:

Sₙ= n/2(a₁ + aₙ)

Where :

a₁ = First term

aₙ = last term

n = number of terms
