Step-by-step explanation:
A citrus grower purchased 25 orange trees and 20 grapefruit trees for $290. The next week, at the same prices, the grower bought 20 orange trees and 30 grapefruit trees for $330. Find the cost of an orange tee and the cost of a grapefruit tree.
Answer:
The cost of an orange tree is $ 6 while that of a grapefruit tree is $
Step-by-step explanation:
Let x be the cost of an orange tree and y be the cost of a grapefruit tree. In the first week, the citrus grower purchased 25 orange trees and 20 grapefruit trees for $290, so 25x + 20y = 290 (1).
In the next week, the grower bought 20 orange trees and 30 grapefruit trees for $330. So, 20x + 30y = 330 (2)
From (2) y = (330 - 20x)/30 = (33 - 2x)/3
substituting y into (1), we have
25x + 20[(33 - 2x)/3] = 290
multiplying through by 3, we have
75x + 20(33 - 2x) = 870
expanding the bracket, we have
75x + 660 - 40x = 870
collecting like terms, we have
75x - 40x = 870 - 660
35x = 210
dividing both sides by 35, we have
x = 210/35
x = 6
substituting x = 6 into y, we have
y = (33 - 2x)/3
= (33 - 2(6))/3
= (33 - 12)/3
= 21/3
= 7
So the cost of an orange tree is $ 6 while that of a grapefruit tree is $ 7.

Answer:
d. -4 <= x - 5
Step-by-step explanation:
I think youre asking about question 5.
First replace the x with the -2 in every problem.
Now solve:
a. 6 × -2 < 10
6 times -2 is -12, and -12 is less than -10, so that ones true and not the answer
b. -2 × -2 > -3
-2 times -2 is 4, and 4 is greater than -3, so that ones true and not the answer
c. -2/4 <= 0
-2 divided by 4 is -1/2, and -1/2 is less than 0. so that ones true and not the answer
So obviously the answers d, but we're gonna check anyway
d. -4 <= -2 - 5
-2 minus 5 is -7, and -7 is not less than -4, so its not true and the answer
Dividing by 3 is the inverse of multipiying by 3.
Yes that is indeed correct

You spent $60 in supplies to sell shirts. You sell your shirts for $10
each. How many do you have to sell to make a profit?
Answer: Atleast 7
Step-by-step explanation:
In order to make a profit you have to amke more money than what you spent for supplies. So if each shirt is 10$ then you would have to sell atleast 7 shirts since if you do you will have made 70$, therefore a 10$ profit. If you sell 6 shirts, you make 60$, meaning you gain all your money back, but you do not make a profit.
the answer is 7
Step-by-step explanation:
7×10=70-60=10
While dining at yet another 5 star restaurant, which is my normal, I received the bill for $95.11 which by the way included an automatic 15% p. Because my generosity is my weakness, I wanted to leave a 20% p, instead. How much should I add to the bill to make this happen?
Answer:
$16.54
Step-by-step explanation:
First step we need to do is to find the bill without the 15% tips:
95.11 = 1.15x
x = $82.70 is the original bill
Now we can add the 20% tips and multiply it into the original:
82.70 x 1.2 = $99.24 is the new bill
To find out how much you tipped:
99.24 - 82.7 = $16.54 is your new tip

Answer:
-20
Step-by-step explanation
To make the sentence into an equation it would be y+13=(-17). To solve this you would need to get y by itself. To do this, you would make the equation y+13-13 , since you need to do the same thing from both sides, it would be y+13-13=(-17)-13 . Simplify the equation to make y=(-7)-13 . Counting back 13 from -7 gets you to -20 . Finally you get to y=(-20) , so the answer is -20

Tank B, which initially contained 80 liters of water, is being drained at a rate of 2.5 liters per minute. How many liters of water remain in the tank after 30 seconds?
Answer:
78.75 ?
Step-by-step explanation:
calculator..
The volume of water remain in the tank after 30 seconds is 78.75 liters.
The given parameters;
initial volume of water in Tank B, V₀ = 80 litersrate at which water is being drained, R = 2.5 liters per minute.time of water drain, t = 30 secondsThe amount of water drained after 30 seconds is calculated as follows;
[tex]V_1 =2.5 \ \frac{liters}{\min} \times \frac{1 \min}{60 \ s} \times 30 \ s\\\\V_1 = 1.25 \ liters[/tex]
The volume of water remain in the tank after 30 seconds is calculated as follows;
V₂ = V₀ - V₁
V₂ = 80 liters - 1.25 liters
V₂ = 78.75 liters
Thus, the volume of water remain in the tank after 30 seconds is 78.75 liters.

Solve the Equation: 2(6b + 1) = 4(b-5)-2 halp me pls, thank you
Answer:
B= -3
Step-by-step explanation:
So first distribute what you can
12b+2=4b-20-2
Now combine like terms
12b+2=4b-22
Now subtract 2 on both sides
12b=4b-24
Now subtract 4b on both sides
8b=-24
Now divide 8 on both sides
b= -3
A sporting goods store manager was selling a ski set for a certain price. The manager offered the markdowns shown, making the one-day sale price of the ski set $323. Find the original selling price of the ski set.
Answer:
The original selling price is $520.632
Explanation:
Consider the initial selling price be $x
After marking down 10%,
Final Selling price = Selling price(1-10%)
Selling price = x – 10% of x = x – 0.1x = 0.9x
After marking 30%
Final Selling price = Selling price(1-10%)
Selling price = 0.9x – 0.3*0.9x = 0.9x – 0.27x = 0.63x
According to the question,
0.63x = 328
Therefore, the original selling price is $520.632
