Answer:
24,950.
Step-by-step explanation:
You can use the arithmetic series formula (a sequence is the list of numbers; a series is the summation of the list).
To find the sum...
(100 / 2) (2 * 2 + (100 - 1)5) = 50 * (4 + 99 * 5) = 50 * (4 + 495) = 50 * 499 = 24950.
Hope this helps!
Answer:
Step-by-step explanation:
Give the expression ax – c = bx + d, we are isolate x i.e we are to make x the subject of the formula.
ax – c = bx + d
Step 1: subtract bx from both sides
ax – c = bx + d
ax-bx = d+c
Step 2: Factor out x in the left hand side of the resulting expression
x(a-b) = d+c
Step 3: Divide both sides by the coefficient of i.e (a-b)
Hence Victoria can justify the step 3 of her work by dividing both sides of the expression in 2 by a-b
