Answer: 13

Step-by-step explanation:

got it right

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.

Find the x- and y-intercepts of the graph of each ... CCSS REASONING The equation 5x + 10y = 60 ... 20. SOLUTION: The x-intercept is the point at which the y-coordinate is 0, or the line ... charges $50 for admission before 6 p.m. and $20 for ... (90, 70). 100 f (100) = 160 – (100). 60. (100, 60). 130 f (130) = 160 – (130). 30.

The interval notation given to us means that x is between negative infinity and 5, excluding both endpoints.

So we can write [tex]-\infty < x < 5[/tex] which shortens to [tex]x < 5[/tex]

The graph will have an open hole at 5 on the number line, and shading to the left to indicate all points smaller than 5.

Answer:

75 = k

Step-by-step explanation:

−60 = −0.8k

Divide each side by -.8

−60/-.8 = −0.8k/-.8

75 = k

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 %

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

Answer:

4 because you divide 3 and 15 by three which gives you 5 then divide 20 by that gives you 4

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

Answer:

The value of X should be 8

Answer:

Step-by-step explanation:

a(x) = 3x + 2

-3,0,5,6

a(-3) = 3*(-3) + 2

a(-3) = - 9 +2

a(-3) = - 7

===============

a(0) = 3*0 + 2

a(0) = 2

================

a(5) = 3*5 + 2

a(5) = 15 + 2

a(5) = 17

================

a(6) = 3*6 + 2

a(6) = 18 + 2

a(6) = 20

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.
