Plzzzzz help I’ll mark brainlest thxxxx
Sloan [31]

an = a1 +d(n-1)

a4 =a1+d(4-1)

-4 = -1+d(3)

add 1 to each side

-3 = 3d

d= -1

an = a1 +d(n-1)

an = -1 +-1 (n-1)

an = -1 -n +1

an = -n

The left and right page numbers of an open book are two consecutive integers whose sum is 385. Find these page numbers.
Alona [7]
Consecutive integers are integers that follow one another. For example, 2,3,4,5,etc.... are consecutive integers

So algebraically, consecutive integers follow the form x, x+1, x+2, etc...

Since the sum of two consecutive integers is 239, this means:

x%2Bx%2B1=239

2x%2B1=239 Combine like terms on the left side

2x=239-1Subtract 1 from both sides

2x=238 Combine like terms on the right side

x=%28238%29%2F%282%29 Divide both sides by 2 to isolate x

x=119 Divide

So our first number is x=119

So to find the next number, simply add 1 to it to get 119%2B1=120

Answer: So our two page numbers are 119 and 120

Use mulipation to find 2 equivalent fractions
laila [671]
1/2 is equivalent to 2/4 because,

2(1/2) = 2/4 

So as you can see if you multiply the numerator(top) and the denominator(bottom) by the same number, you get an equivalent fraction! In my example you can see that I multiplied both by 2.
