Answers
Answer: C
Step-by-step explanation:
The triangle in the picture is an equilateral triangle. We know this is true because all sides are equal, as denoted by the tick marks. In equilateral triangles, each angle is 60° because when you add all the angles, you get 180°.
4x+8=60 [subtract both sides by 8]
4x=52 [divide both sides by 4]
x=13
Now, we know that C is the correct answer.

When Sergio went to dinner with his brother, the bill was $51.19. What was the total they paid if they left a 15% tip?
Answers
Answer:
The total they paid was $58.8685
Step-by-step explanation:
Let us solve the question using the percentage method
∵ Sergio went to dinner with his brother
∵ The bill was $51.19
∵ They left a 15% tip
→ That means they pay extra money 15% of $51.19
∴ The total they paid = the bill + 15% of the bill
∵ 15% of the bill = 15% × 51.19
→ Change 15% to a decimal by divide it by 100
∴ 15% of the bill = [tex]\frac{15}{100}[/tex] × 51.19
∴ 15% of the bill = 0.15 × 51.19
∴ 15% of the bill = $7.6785
→ Substitute it in the total they paid
∵ The total they paid = 51.19 + 7.6785
∴ The total they paid = $58.8685
∴ The total they paid was $58.8685

There are 90 calories in a 3/4 cup serving of cereal.
How many calories are in 1 cup?
How many calories are in 6 cups?
90
3/4
=1
=6
Answers
Answer:
120 calories in 1 cup, 720 in 6 cups
Step-by-step explanation:
I divided 90 by 3 to get 1/4 cup and then multiplied it by 4 to get for one cup. From there I multiplied by 6
Answer:
1 cup=120 calories 6 cups=720 calories
Step-by-step explanation:
We know that there are 90 calories in 3/4 of a cup and we can figure out that 30 calories are in each 1/4 of a cup because 90 divided by 3 equals 30 then just add 30 calories to 90 and get 120. Finally just do 120 times 6 and get 720 .

0
Step-by-step explanation:
Step-by-step explanation:
okay, 7 (n) if n = 4 that means 7 times 4 so that equals 28 BUT we do (m + 18) first so if m= 10 that means (10 + 18) would be 28, so
28 - 28= 0

c ≈ 5.83095189485
Step-by-step explanation:
We can use the Pythagorean Theorem [tex](a^{2} +b^{2} =c^{2} )[/tex] for these kinds of problems.
So, pretend that line is the hypotenuse of a right triangle. One side would be
3 units long and another would be 5 units long. Let's plug that into the theorem.
3² + 5² = c²
Simplify.
9 + 25 = c²
Add.
34 = c²
And now square root both sides.
√34 = c
c ≈ 5.83095189485

The constraints that represent the given situation in the question are; Option D;
f ≥ 0
m ≥ 0
f ≤ 30
45m + 30f ≤ 30
InequalitiesWe are told that;
Maths sessions (m) are 45 minutes long per week. French sessions (f) are 30 minutes long per weekThus; we can say that; m ≥ 0 and f ≥ 0
We are told that Mary doesn't want to deliver more than 30 French sessions in one week. Thus;
f ≤ 30
Combining all the inequalities, we can say that;
45m + 30f ≤ 30
