Answer:
Step-by-step explanation:
A line in 2-dimensional space has the following general equation:
Where m is the slope of the line, and b just a number
the slope can be obtaine using th following formula:
The point 2 is the one with the smallest value for x, that is (-10,-7) and the Point 1 is any other that belongs to the line, in this case, (-5,-9)
Resulting that
To find the other term we can use any other point, I prefer us the first one so...
We have the following equation:
Resulting that b=18
I just have to eval the point (-10,-7) in the equation stated at the beginning knowin that m was calculated previously.
Step-by-step explanation:
Answer: 16 and 5/4 tbsp of sugar.
7 ÷ 2 = 3.5
Don't worry about the decimal for now, just find how many tbsp of sugar she needs for 6 tbsp of milk.
6 ÷ 2 = 3
3 x 5 = 15
Now, we will focus in the 0.5 tbsp of milk.
Find how much 1/2 a tbsp of milk can get for sugar.
4 1/2 tbsp of milk is 5 tbsp of sugar.
5 ÷ 4 = 1.25
So 16 and 5/4 tbsp of sugar is required.
(Answer for Part A)
Answer:
46
Step-by-step explanation:
There is an open + in the middle. It does not have any brackets around it. Therefore you do it at the very last.
Left side of the plus sign.
[16 ÷ (2 + 3*2)] Do the multiplication inside the parenthesis ( 2*3) first.
= [16 ÷ (2 + 6)] Add inside the parenthesis.
= [16 ÷ 8 ] Do the division
= 2
Right side of the open plus sign
[4 * (36 - 25)] Do the subtraction first.
[4 * 11 ] Do the multiplication
44
Now combine both right and left side.
2 + 44
46
The answer is 46.
