Answer:
-2
Step-by-step explanation:
3 + - 5 is basically 3 -5 because when a negative meets a positive the signs turn into a negative.
3 -5 is 5 less than three which is -2.
find the distance traveled in 15 seconds by an object moving with a velocity of v(t)= 20 + 3t feet per second where t is the time in seconds.
Answer:
4 because you divide 3 and 15 by three which gives you 5 then divide 20 by that gives you 4

A student has passed 60 percent of the 20 quizzes he has written so far successfully. If the student writes 50 quizzes during the year, and passes 80 percent of the remaining quizzes successfully, what would his average percentile be?
Answer:
A student has passed 60 percent of the 20 quizzes he has written so far successfully mean:
successfully quizzes = 60 % of 20 quizzes = ( 60 / 100 ) * 20 = 60 * 20 / 100 = 1200 / 100 = 12
The remaining quizzes = 50 - 20 = 30 quizzes
80 percent of the remaining quizzes successfully mean:
The remaining successfully quizzes = 80 % of 30 = ( 80 / 100 ) * 30 = 80 * 30 / 100 = 2400 / 100 = 24
Total successfully quizzes = 12 + 24 = 36
Average = ( 36 / 50 ) * 100 % = 0.72 * 100 % = 72 %
Pls rate Brainliest!
Answer:73%
Step-by-step explanation:A student has passed 60 percent of the 20 quizzes he has written so far successfully mean:
successfully quizzes = 60 % of 20 quizzes = ( 60 / 100 ) * 20 = 60 * 20 / 100 = 1200 / 100 = 12
The remaining quizzes = 50 - 20 = 30 quizzes
80 percent of the remaining quizzes successfully mean:
The remaining successfully quizzes = 80 % of 30 = ( 80 / 100 ) * 30 = 80 * 30 / 100 = 2400 / 100 = 24
Total successfully quizzes = 12 + 24 = 36
Average = ( 36 / 50 ) * 100 % = 0.72 * 100 % = 72 %

Diego pays $4.50 for 3 pounds of bananas and 2 pounds of oranges. one pound of oranges cost $0.75 more than one pound of bananas let b represent the price per pound of bananas. Which equation represents the situation, and what is the price per pound of each fruit? 3b + 2b = 4.50; $0.90 per bananas, $0.90 per pound of oranges 3b + 2(0.75) = 4.50; $1.00 per bananas, $1.75 per pound of oranges 3b + 2(b + 0.75) = 4.50; $0.60 per bananas, $1.35 per pound of oranges 3b + 2b = 4.50; $1.35 per bananas, $0.60 per pound of oranges
Given:
Diego pays $4.50 for 3 pounds of bananas and 2 pounds of oranges.
One pound of oranges cost $0.75 more than one pound of bananas.
To find:
The equation which represents the situation, and what is the price per pound of each fruit.
Solution:
Let b represent the price per pound of bananas.
Cost of 3 pound of banana = $3b
One pound of oranges cost $0.75 more than one pound of bananas.
So, cost of one pound of oranges = $(b+0.75)
Cost of 2 pound of oranges = $2(b+0.75)
Diego pays $4.50 for 3 pounds of bananas and 2 pounds of oranges.
[tex]3b+2(b+0.75)=4.50[/tex]
Therefore, the required equation is [tex]3b+2(b+0.75)=4.50[/tex].
On solving the above equation, we get
[tex]3b+2b+1.50=4.50[/tex]
[tex]5b=4.50-1.50[/tex]
[tex]5b=3[/tex]
Divide both sides by 5.
[tex]b=\dfrac{3}{5}[/tex]
[tex]b=0.60[/tex]
Now,
[tex]b+0.75=0.60+0.75=1.35[/tex]
Therefore, the price of fruits are $0.60 per bananas, $1.35 per pound of oranges.
Hence, the correct option is C.

A granola bite contains 27 calories. Most of the calories come from grams of carbohydrates. The rest come from other ingredients. One gram of carbohydrate contains 4 calories.The equation represents the relationship between these quantities. What is the prolom asking you to find? * 4c + 5 = 27
Answer:
Quantity of carbohydrate in gram = 5.5 gram
Step-by-step explanation:
Given:
Amount of calories contain = 27
1 gram carbohydrate = 4 calories
Equation : 4c + 5 = 27
Find:
What is c
Computation:
Equation asking for quantity of carbohydrate in gram
So,
4c + 5 = 27
4c = 22
c = 5.5
Quantity of carbohydrate in gram = 5.5 gram
What is the variable expression that represents the word phrase.
The product of 2 and x is increased by 7
Answer:
2x + 7
Step-by-step explanation:
The product of 2 and x
Product means multiplication
The product of 2 and x means multiplication of 2 and x
Which is equivalent to
2 * x = 2x
The product of 2 and x is increased by 7
That is, 7 is added to the product of 2 and x
Here,
2x + 7
The variable expression that represent the word phrase "The product of 2 and x is increased by 7" is 2x + 7

A drone costs $200, and you receive a 15% discount due a coupon. What is
the total amount to be paid?
Answer:
the total would be 170 dollars
Step-by-step explanation:
200x0.15
Answer:
$170
Step-by-step explanation:
15% of 200 is 30, so subtracting 30 from 200 gets you 170.
If you're having trouble with finding 15% of 200, just flip it around, and find 200% of 15. 15% of 200 and 200% of 15 are both 30. This works no matter what numbers you have. For example, 8% of 100 and 100% of 8 are equivalent, 70% of 200 and 200 and 200% of 70 are equivalent as well.

The measure of the supplement of an angle is three times the measure of the
angle.
Find the measures of the angle and its supplement.
Let the angle to be solved be x
Let the supplement/compliment by y
x+y=90 Complimentary angles add up to 90 degrees.
x+3y=180 Supplementary angles add up to 180 degrees, the other angle is thrice the other compliment.
Evaluating this as a system:
x+y=90 Isolate x:
x=90−y Input into the other equation:
(90−y)+3y=180 Combine like terms, isolate y and its coefficients:
2y=90 Isolate y
y=45 Input into the first equation:
x+45=90 Isolate x:
x=45degrees

Sammy bought 15.3 Liters of milk. She poured the milk equally into 5 bottles. There was 0.35 liters of milk left over. Calculate the capacity of milk in 1 bottle.
please show work.
Answer:
The capacity of milk in 1 bottle is 2.99 liters
Step-by-step explanation:
Let us solve the question
∵ Sammy bought 15.3 liters of milk
∵ She poured the milk equally into 5 bottles
∵ There were 0.35 liters of milk leftover
→ At first, subtract the leftover from the quantity she bought to
find the capacity of the five bottles
∴ The capacity of the 5 bottles = 15.3 - 0.35
∴ The capacity of the 5 bottles = 14.95 liters
→ To find the capacity of each bottle divide the total capacity by 5
∴ The capacity in one bottle = 14.95 ÷ 5
∴ The capacity in one bottle = 2.99 liters
∴ The capacity of milk in 1 bottle is 2.99 liters
