Answer:
$0.75 per candy bar
Step-by-step explanation:
For this problem, we simply need to set up a system of equations to find the value of a drink, and the value of a candy bar.
Let x represent the cost of a candy bar, and y represent the cost of a drink.
60x + 110y = 265
120x + 90y = 270
Now let's use the elimination method to solve for one of the variables:
60x + 110y = 265 --> -2 ( 60x + 110y = 265 ) --> -120x + -220y = -530
-120x + -220y = -530
120x + 90y = 270
-130y = -260
y = 2
Now plug the value of y into one of the equations to find the value for x:
60x + 110y = 265
60x + 110 (2) = 265
60x + 220 = 265
60x = 45
x = 45 / 60
x = 0.75
With this, we know that the cost of a candy bar is $0.75 and the cost of drink is $2.00.

If the angles of a triangle are (2y - 5)degrees, (y + 20)degrees, and (3y-5) degrees what are the values of the angles
Answer:
[tex] \boxed{ \boxed{ \bold{ \sf{51.68 \: , \: 48.34 \:, \: 80.02}}}}[/tex]Step-by-step explanation:
Let's solve:
As we know that the sum of angles of traingle adds to 180°
[tex] \sf{2y - 5 + y + 20 + 3y - 5 = 180}[/tex]
Collect like terms
⇒[tex] \sf{6y - 5 + 20 - 5 = 180}[/tex]
⇒[tex] \sf{6y + 15 - 5 = 180}[/tex]
⇒[tex] \sf{6y + 10 = 180}[/tex]
Move constant to right hand side and change it's sign
⇒[tex] \sf{6y = 180 - 10}[/tex]
Calculate the difference
⇒[tex] \sf{6y = 170}[/tex]
Divide both sides of the equation by 6
⇒[tex] \sf{ \frac{6y}{6} = \frac{170}{6} }[/tex]
Calculate
⇒[tex] \sf{y = 28.34}[/tex]
Now, let's replace the value:
⇒[tex] \sf{2y - 5 = 2 \times 28.34 - 5 = 51.68}[/tex]
⇒[tex] \sf{y + 20 = 28.34 + 20 = 48.34}[/tex]
⇒[tex] \sf{3y - 5 = 3 \times 28.34 - 5 = 80.02}[/tex]
Hope I helped!
Best regards!!
Answer:
51 2/3 , 48 1/3 and 80 degrees.
Step-by-step explanation:
The 3 angles add up to 180 degrees.
2y - 5 + y + 20 + 3y - 5 = 180
6y + 10 = 180
6y = 180 - 10
6y = 170
y = 170 / 6 = 28 1/3 degrees.
So the 3 angles are 2(28 1/3) - 5, 28 1/3 + 20 and 3(28 1/3) - 5.
The cost C of mailing a letter first class in the United States is $0,45 for the first ounce.
Each added ounce, or fraction of an ounce, o, costs an additional $0.20.
1. Write an equation to represent the total cost, C, to mail a first class letter that
weighs n ounces.
C=
Answer: C= 0.25 + 0.20n
Step-by-step explanation:
Let n be the number of ounces of the letters.
As per given,
Cost per ounce = $0.45
Additional cost per ounce = $0.20
So, the equation to represent the total cost, C, to mail a first class letter that weighs n ounces will be
C= 0.45 + (n-1)(0.20)
⇒ C= 0.45 + 0.20n-0.20
⇒ C= 0.25 + 0.20n
Hence, the required equation is C= 0.25 + 0.20n .

Bruce wants to find the perimeter of a rectangular plot of land. The length is (6x-29) km. The width measures (5x-17) km. What is the perimeter of the plot of land
Units for the perimeter are in kilometers
==============================================
Work Shown:
L = length = 6x-29
W = width = 5x-17
P = perimeter of rectangle
P = 2*(L + W)
P = 2*(6x-29 + 5x-17)
P = 2*(11x - 46)
P = 2*11x + 2*(-46)
P = 22x - 92
If we knew the value of x, then we could find the actual numeric value for the perimeter. However, we don't have that info, so we leave it as is.

NEED HELP ASAP ALGEBRA 2
Answer:
a=9
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle
a^2 + b^2 = c^2
a^2 +40 ^2 = 41^2
a^2 + 1600 = 1681
a^2 = 1681-1600
a^2 = 81
Take the square root of each side
sqrt(a^2) = sqrt(81)
a = 9
Answer:
9.
Step-by-step explanation:
Pythagoras Theorem is used in this case:
a² + b² = c²
a² + 40² = 41²
a² + 1600 = 1681
a² = 1681 - 1600
a² = √81
a = 9
9 is the third answer.

during a basketball game, your team scored three times as many 2-point field goals than it did 3-point field goals, and scored a total of 90 points. How many field goals did your team score?
Answer:
40 field goals
Step-by-step explanation:
Represent 2-point with x and 3-point with y;
Given
[tex]x = 3y[/tex]
[tex]2x + 3y =90[/tex]
Required
Determine x and y
[tex]x = 3y[/tex]
[tex]2x + 3y =90[/tex]
Substitute 3y for x in [tex]2x + 3y =90[/tex]
[tex]2(3y) + 3y = 90[/tex]
[tex]6y + 3y = 90[/tex]
[tex]9y = 90[/tex]
Divide both sides by 9
[tex]y = 10[/tex]
Substitute 10 for y in [tex]x = 3y[/tex]
[tex]x = 3 * 10[/tex]
[tex]x =30[/tex]
The number of field goals = x + y
[tex]x + y = 30 + 10[/tex]
[tex]x + y = 40[/tex]
Hence, the number of field goals is 40
Cool Down: Almond Bags Bags of almonds from a food producer are advertised to weigh 500 grams each. Twenty bags of almonds are weighed. The scatter plot shows the absolute error between the actual weight and the advertised weight of those bags. Estimate the largest absolute error.
Answer:
12 grams
Step-by-step explanation:
Absolute error is the difference between the measured value and the actual value.We can see on the plot that absolute error is spread between zero and 12 grams.
The largest absolute error is approximately 12 grams as per plot on the top right. It gives the bag weight of 512 grams vs advertised 500 grams.

Given: The ratio of the number of boys to the number of girls at Liam's school is 4:5. There are 270 students at his school. Statement 3: There are exactly 30 more girls than boys. True False Explain your thinking.
Answer: True
Step-by-step explanation:
Given: The ratio of the number of boys to the number of girls at Liam's school is 4:5.
There are 270 students at his school.
Then, Total boys = [tex]\dfrac{4}{4+5}\times270=\dfrac{4}{9}\times270=120[/tex]
Total girls =[tex]\dfrac{5}{4+5}\times270=\dfrac{5}{9}\times270=150[/tex]
Clearly, (Number of girls) > (Number of boys)
Difference = (Total girls) - (Total boys)
= 150-120
= 30
So, Statement 3: "There are exactly 30 more girls than boys". is absolutely true.

If a number line shows tick marks that are not labeled, can you determine the coordinate of a point located at an unlabeled tick mark?
If other tickmarks are labeled, then you could do some detective work (of sorts) to figure out the unlabeled tickmarks.
For example, let's say we had a number line with 1,2,3,... and let's say that 7 was covered up or erased or smudged. So we have 1,2,3,4,5,6,__,8,9. We could then easily determine that 7 must go in that blank spot. This is just one example of course.
Another example could be that if we had a tickmark right in the middle of two whole numbers, say 0 and 1. This unlabeled tickmark would most likely be 1/2 = 0.5 as its at the halfway point between 0 and 1.
