What’s 2(b+3y+4z+7) if b=3 and y=6 and z=1

64

Step-by-step explanation:

You need to substitute the value of each number into its corresponding variable

2(3 + 3(6) + 4(1)+ 7)

You multiply to get this

2(3+18+4+7)

You then add all of the numbers up to get this

2(32)

Then, multiply 2 by 32 to get 64

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
