Answer is D) take 5 blocks away from the left side.

There are 8 blocks on the left and only 3 on the right, 8 - 3 = 5

Since there are 8 block on the left side and 3 on the right side, they have to have the same amount to be equal.

A) 8 = 3 + 3 → 8 = 6? No, this isn't right

B) 8 = 4 + 3 → 8 = 7? Nope

C) 8 - 3 = 3 → 5 = 3? No

D) 8 - 5 = 5 → 3 = 3? Yes, so to balance the two sides you would need to take 5 blocks from the left side (or add 5 to the right side but that isn't a choice)

Translating a sentence into a multi-step equation
Kryger [21]

Answer:7x-4= 3

Step-by-step explanation:

4 less than the product of 7 and a number is equal to 3.

The answer is 7x-4= 3 beacuse:

(a.  whenever you have something less than , the first number in the sentence (in this cacse 4) goes after the second number (in this case 7) with a subtraction sign in the middle. (imagine this equation looking like 7-4 <u>for now)</u>.Thats a little trick i use whenever i have to write "something less than something"

(b. okay so now we know it has to be 7 times somethig -4=3, but now we just need to write the "product of 7 and a number" in proper form. in other words, whenever you get somethig times a number, it is always going to be  that number with an x right next to it. so thats why i made it 7x.

(c. "equals 3" is easy because you just turn it into an "=3".

(d. Now put it together. "4 less than the product of 7 and a number is equal to 3." becomes 7x-4=3.

Hope this helps :)) Also brainliest would be appreciated, worked pretty hard on this ! :D

 <span>P(t) = Po(1 - r)^t 

P(t) = price after t months --> S 
Po = initial price -- P 
r = rate as a decimal 

S = P(.9)^4

Please help to find an explicit formula for calculating the sum Mn
defon

The explicit formula for calculating the sum is

S_N=\frac{n(n-1)}{2} \cdot\frac{n(n+1)}{2}

The sum of the nth term of a sequence is expressed as;

S_n=\frac{n}{2}(2a+(n-1)d)

a is the first term

d is the common difference

n is the number of terms

For the sequence  0 + 1 + 2 + 3  +...

S_n=\frac{n}{2}(2(0)+(n-1)1)\\S_n= \frac{n}{2}(n-1)\\S_n= \frac{n(n-1)}{2}

Similarly for the sequence:

1 + 2+ 3 + 4+...

S_n=\frac{n}{2}(2(1)+(n-1)1)\\S_n= \frac{n}{2}(2+n-1)\\S_n= \frac{n(n+1)}{2}

Taking the product of the sum to get the explicit formula for calculating the sum

S_N=\frac{n(n-1)}{2} \cdot\frac{n(n+1)}{2}
