Find the common difference if the 8th term is 55 and the first term is 13

Vlad [161]

Answer:

Step-by-step explanation:

Equation

L = a + (n - 1)*d

Givens

L = 55

a = 13

n =8

Solution

55 = 13 + (8 - 1)*d Combine

55 = 13 + 7d Subtract 13 from both sides

55 - 13 = 7d

42 = 7d Divide by 7

d = 6

7.5% of what number is equal to 85% of 200?

Ksivusya [100]

Solving:

$\frac{7.5}{100} *x = \frac{85}{100} * 200$

$\frac{7.5x}{\diagup\!\!\!\!\!\!\!\!100} = \frac{17000}{\diagup\!\!\!\!\!\!\!\!100}$
$7.5x = 17000$
$x = \frac{17000}{7.5}$
$x = 2266.6666... \:\to \boxed{\boxed{x \approx 2266.67}}\end{array}}\qquad\quad\checkmark$
