Tisha and her academic team are working to go to state finals. They must have a certain number of points, T, to advance. They have had three local matches, b, c and d, and will attend a district match. District match points count for four times the number of points than local matches do. Choose the equation that would help Tisha find how many points they need to earn in the district match, a, to advance. a equals T over 4 minus b minus c minus d a equals T minus b minus c minus d all over 4 a equals T plus b plus c plus d all over 4 a = 4(T − b − c − d)

b equals T minus a minus c minus d all over 3 ⇒ 3rd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- Tisha and her academic team have had three local matches

# Assume that the points of the local matches are a , c , d

- They will attend a district match

- District match points count for three times the number of points

than local matches do

# Assume that the points of the district match is b

- T is the total points they will earned in the four matches

∵ The points in the local matches are a , c , d

∵ The point in district mach is 3b

∴ T = a + c + d + 3b

* Lets find b in terms of a , c , d , T

∵ T = a + c + d + 3b

- Subtract a from both sides

∴ T - a = c + d + 3b

- Subtract c from both sides

∴ T - a - c = d + 3b

- Subtract d from both sides

∴ T - a - c - d = 3b

If a 23-ounce box of cereal costs $2.89, what should a 30/ounce box cost?

Answers

Answer:

$3.77

Step-by-step explanation:

We can find the unit cost in dollars per ounce.

$2.89 / 23 oz = $0.1256/oz

Now we multiply the unit cost by 30 oz.

$0.1256/oz * 30 oz = $3.76956

Answer: $3.77

Death Valley has an altitude that is below sea level. Which situation describes a hiker in Death Valley who hikes until he reaches an altitude of 0 feet?

A - The hiker starts at 0 feet then decreases their altitude by 10 feet.
B - The hiker starts at -10 feet then decreases their altitude by 10 feet.
C - The hiker starts at 10 feet then increases their altitude by 10 feet.
D - The hiker starts at -10 feet then increases their altitude by 10 feet.

Answers

Answer: D

Step-by-step explanation:

Think of it logically: A and C are not below sea level so you can cross them out. And B doesn't work because if you decrease -10 by 10 you get -20. So, D is correct.

Answer : D because they started below 0 then reached 0

ANSWER CORRECTLY DONT EXPLAIN

Answers

Answer:

336

Step-by-step explanation:

A square has four equal sides therefore you know the perimeter is 20+20+20+20 = 80. Since the square and the rectangle have the same perimeter the perimeter of the rectangle is also 80. We already know that two of the sides are 28 cm long so we can subtract those two sides from 80. That gives us 24 which is the sum of the two remaining sides. Each of these sides is 24/2 which is equivalent to 12. The formula for area of a rectangle is length times width. Your length is equal to 28 and your width is equal to 12. When you multiply these you get 336 which is your final answer.

Hey i'm Nate

So for this you want to use order of operations AKA (PEMDAS)

P: Parenthesis

E: Exponents

M: Multiplication

D: Division

A: Addition

S: Subtraction

You want to work in that order however Multiplication and Division can be alternated likewise with Addition and Subtraction. So for this question you would take the problem which is 4__ 6 -2 x4 +511 = 527  and then you plug in the signs to see which one works. The answer would be X because you would take -2x4 which is -8 then you would take 6x4 which is 24 then you subtract -8 and 24 and you get 16 then you take 16 and add 511 and then you get 527.

Therefore the answer is X
