Factor the expression:<br> 16y-8
natima [27]

Answer: 8 (2y-1)

Step-by-step explanation: first start by writing like this below:

16y-8

Then factorise the numbers(cut the numbers)

2×2×2×2×y - 2×2×2

Now take all which is common like:

2×2×2=8

Then,take the remained numbers and add it into the brackets.

8 (2y - 1) Here, why we should put 1,because there's nothing left.

If you want to check the answer, factorise this expression and see:

8 (2y-1)

16y-8.

Hope it helps you!!

For Tammy's wedding she wants to
zmey [24]

Answer:

She can only buy 12 centerpieces.

Step-by-step explanation:

To solve this question, we must first create an expression. We know that the total would be $1000. The delivery is included in that budget and it is a constant. EACH centerpiece is $80. From that information, you can build an expression.

80c + 35 = 1000

-------------------------------------

Next, you will need to solve for c, or any variable you choose. If you solve it, you will be left with:

c= 12.06

--------------------------------------

Since you cannot buy a fraction of a centerpiece, this concludes that the answer would be 12.

Good Luck!!
