Answer:
4 questions
Step-by-step explanation:
To find a percentage of a number, you move the decimal mark all the way to the left.
87.5% becomes 0.875
Next you multiply 32 by 0.875 to find the percentage of questions that are completed
32 x 0.875 = 28
28 out of 32 questions have been solved, so now you subtract 28 from 32
32 - 28= 4
There are 4 questions to complete
Answer:
35d+ 32 > 25d+68
Step-by-step explanation:
Plan A: $35 a day plus a fee of $32
35d+ 32
Plan B: $25 a day plus a fee of $68
25d+68
We want to know when A costs more than B
35d+ 32 > 25d+68
The most cookies Heidy can make is 36 cookies.
<h3>How to calculate how many cookies can Heidy make?</h3>
To know how many cookies Heidy can make, you have to take into account the following information:
12 cookies need the following ingredients:
- 125g butter
- 200g flour
- 50g sugar
In the case in which Heidy has more ingredients, we must carry out the following operations:
Divide the quantities, in the reference quantity we have:
- 500g of butter ÷ 125g of butter = 4
- 700g flour ÷ 200g flour = 3.5
- 250g of sugar ÷ 50g of sugar = 5
According to the above, we must take into account the lowest value of all because if that ingredient is enough, we can infer that the rest of the ingredients also.
So the number of cookies Heidy can make are:
12 × 3.5 = 42

2x + 4 = 12
We're simply just trying to isolate x.
So, we must get x onto it's own side of the equal sign :)
Our first step is to subtract 4 from both sides.
2x + 4 - 4 = 12 - 4
Simplify.
2x = 8
Then, we divide both sides by 2.
2x ÷ 2 = 8 ÷ 2
Simplify.
x = 4
----------
To check your work, simply plug in the value of x into x in the original equation.
In this problem, x = 4, so plug in 4 for x.
2x + 4 = 12
2(4) + 4 = 12
Simplify.
8 + 4 = 12
12 = 12
Therefore, x = 4
