Arisa [49]

<u><em>Answer:</em></u>

<u>She will use:</u>

3 tablespoons of pepper

7 tablespoons of garlic powder

\frac{1}{4} tablespoon of thyme

8 tablespoons of onion powder

<u><em>Explanation:</em></u>

To double the amount, Stephanie will need to double the amount of each ingredient used. This means that she will multiply each amount by 2

<u>Therefore:</u>

New amount of any ingredient = old amount of that ingredient x 2

<u>This means that:</u>

New amount of pepper = 1\frac{1}{2}*2= 3 tablespoons

New amount of garlic powder = 3\frac{2}{4}*2=7 tablespoons

New amount of thyme = \frac{1}{8}*2=\frac{1}{4} tablespoons

New amount of onion powder = 4*2=8 tablespoons

Hope this helps :)

Simplify the expression completely. 7b+3(4b−2)+6÷3
Karo-lina-s [1.5K]

Answer:

19b-4

Step-by-step explanation:

7b+3(4b-2)+6÷3

Bracket comes first so we distribute 3 over the terms in the bracket

= 7b + 12b -6 +6 ÷ 3

First we solve division

= 7b + 12b -6 +6 ÷ 3

= 7b + 12b -6 +2

= (7b+12b)+(-6+2)

= 19b -4

This can't be simplified further as it can't be solved anymore
