(8v3-80v2+6)\(v-10)

Leto [7]

$\frac{(8v^3-80v^2+6)}{v-10}$

Use long division for dividing

$(8v^3-80v^2+6)$ Here 'v' term is missing so we use 0vW

Divide $(8v^3-80v^2+0v+6)$ by v-10 using long division

Step 1: Put 8v^2 at the top

step 2: multiply 8v^2 with v-10 and put it at the bottom

step 3: subtract it

We will get remainder 6

so quotient is $8v^2$

Remainder is 6

Hi:) I need help with part 9(ii) ? Thanks :)!

Goshia [24]

Answer:

see explanation

Step-by-step explanation:

Given

2BD = 7BT , then

2(d - b ) = 7(t - b) ← distribute both sides

2d - 2b = 7t - 7b ( add 7b to both sides )

2d + 5b = 7t, thus

2 $\left[\begin{array}{ccc}10.5\\10\\\end{array}\right]$ + 5 $\left[\begin{array}{ccc}0\\3\\\end{array}\right]$ = 7t

$\left[\begin{array}{ccc}21\\20\\\end{array}\right]$ + $\left[\begin{array}{ccc}0\\15\\\end{array}\right]$ = 7t

$\left[\begin{array}{ccc}21\\35\\\end{array}\right]$ = 7t , thus

t = $\frac{1}{7}$ $\left[\begin{array}{ccc}21\\35\\\end{array}\right]$ = $\left[\begin{array}{ccc}3\\5\\\end{array}\right]$

Hence T = (3, 5 )

Stephanie has the same number of dimes and nickels. She has $6.10 in all. Write an equation that you could use to find the numbe

Igoryamba

Answer:

The equation is

15x = 610

Step-by-step explanation:

A dime is 10 cents while a nickel is 5 cents

$6.10 is same as 610 cents

Let the number of dimes and number of nickels be x

10x + 5x = 610

15x = 610
