Jade normally leaves work at 5:00 pm, but she is leaving work 10 minutes late today. She decides to make up time by taking the toll road instead of side streets. She can travel two times faster by taking the toll road. Create an equation in terms of x to represent the number of minutes after 5:00 pm she arrives home from work if she leaves late. Let x represent the number of minutes her normal commute takes when she leaves on time.

Otto used 5.5 cups of whole wheat flour and x cups of white flour in the recipe. What is the equation that can be used to find the value of y, the total amount of flour that Otto used in the recipe, and what are the constraints on the values of x and y?y=5.5x; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 5.
y=5.5x; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 5.5.
y=x+5.5; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 5.
y=x+5.5; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 5.5.

Answers

Answer: y = x + 5.5

Step-by-step explanation:

This situation of the recipe can be represented as y=x+5.5 and it is expected that x is ≥ 0 and y is ≥ 5.5.

What is the equation for this situation?

It is known the total amount of flour (y) is equivalent to the total amount of whole wheat flour (5.5) added to the total white flour (x). Therefore, the equation is:

What are the possible values?

x = It is expected x is equalthan 0 or greater to it since the minimum amount of white flour that can be added is 0.

y = It is expected y is equal than 5.5 or greater to it since even if no white flour is added the minimum total is 5.5.

If a soccer team played 160 games and won 65% of them, how many games did they win?

Answers

The correct answer is 104 games.

You get that number by dividing 160 with a 100, to find out how large 1% is, and then you multiply it with 65 to find out how much 65% is, and the answer is 104 games.

6(7a-10) how do I solve this

Answers

$6(7a-10) \n \n 6 * 7a + 6 * -10 \ / \ distribute \n \n 42a + 6 * -10 \ / \ simplify \n \n 42a + -60 \ / \ simplify \n \n 42a - 60 \ / \ simplify \n \n Answer: \fbox {42a - 60}$

solve the brackets, to do that you should multiply the numbers inside the bracket with the first number outside and in the right to the brackets.so,

6(7a-10)= 42a-60
hence the answer is, 42a-60

Solve the equation x+10=30

Answers

get x alone on one side and solve

x = 30 - 10
x = 20

X+10=30
Subtract 10 from both sides
X+10=30
-10 -10
X=20
Answer:
X=20

The sum of two numbers is 30 & their difference is 12.

Answers

x+y=30
x-y=12
add them together

x+y=30
x-y=12+
2x+0y=42

2x=42
divide 2
x=21

subsitute
x+y=30
21+y=30
subtrat 21
y=9

number sare 21 and 9

The answer is 21 and 9. You can use guess and check to solve this. If you add 21 and 9, the sum is 30, and if you subtract 9 from 21, the difference is 12.
