Answer:
Selection to make is C, D, E
Step-by-step explanation:
Let the cost of a package of tulip bulbs be $x while the cost of a package of daffodil bulbs be $y
10 tulip = $10x
14 bulbs = $14y
The addition of both gives a total $402
10x + 14y = 402 •••••••(i)
11 tulip = $11x
4 dudafodil = $4y
Total is 237
11x + 4y = 237 ••••••••(ii)
So let’s solve to get the value of x and y
10x + 14y = 402
11x + 4y = 237
Divide equation 1 by 2
5x + 7y = 201
11x + 4y = 237
Multiply equation 1 by 4 and 2 by 7
20x + 28y = 804
77x + 28y = 1659
Subtract i from ii
57x = 855
x = 855/57
x = 15
Recall;
5x + 7y = 201
5(15) + 7y = 201
75 + 7y = 201
7y = 201-75
7y = 126
y = 126/7
y = 18
Cost of tulip is $15, cost of daffodil is $18
Help me with this question plz!!!
2x - 4=x+6
Answer:
x = 10Step-by-step explanation:
2x - 4 = x + 6 add 4 to both sides
2x - 4 + 4 = x + 6 + 4
2x = x + 10 subtract x from both sides
2x - x = x - x + 10
x = 10

Car a travels 15 miles while car b travels 26 miles what is the ratio of car a to car b
Answer: 15:26
Step-by-step explanation:
Given: Car a travels 15 miles while car b travels 26 miles.
Now, the ratio of the distance traveled by car a to car b is given by :-
[tex]\dfrac{\text{15 miles}}{\text{26 miles}}=\dfrac{15}{26}[/tex] , which is the fraction in the simplest as highest common factor of 15 and 26 =1.
So, the the ratio of the distance traveled by car a to car b = 15:26
Hence, the ratio of car a to car b = 15:26
If the perimeter of a
square is 60 feet, what is
the area of the square?
Answer:
225 ft I believe
Step-by-step explanation:
Answer:
225
Step-by-step explanation:
Well, the formula for perimeter is simply 2 times length + 2 times width. In the case of our square, this would simply be 2x+2x (since length = width), or 4x . Therefore, if given an area, all you'd do is take the square root (to get from x2 to x , and then multiply by 4 to find perimeter.

Answer:
1. x= 17
2. x= 31
3. x= 4
4. x= 40
Step-by-step explanation:
first one:
you pass the 10 dividing
x-7 = 100/10 ----> x-7 =10
Pass the 7 adding
x = 10+7 ---> x= 17
second one:
Pass the 7 multiplying
x+11= 6*7 ---> x+11= 42
Pass the 11 in substraction
x = 42-11 ----> x =31
third one:
Add the 3+8 = 11
Pass the 11 dividing
x*11 = 44 -----> x= 44/11 ---> x= 4
fourth one:
Rest the 8-4 = 4
Pass the 4 multiplying
x/ 4 = 10 -----> x = 4*10 ---> x= 40

10.2 and 25.5
198:1,287 and 2:13
Step-by-step explanation:
5:1 and 15:3 is equivalent because 5 ⋅ 3 = 15, and 1 ⋅ 3 = 3.

what is the common difference between successive terms in the sequence
9,2.5,-4,-10.5,-17
Let's find the difference between two consecutive terms
2.5 - 9 = -6.5
-4 - 2.5 = -6.5
-10.5 - (-4) = -6.5
-17 -(-10.5) = -6.5
We can see that the common difference is -6.5
-6.5 is the common difference between successive terms in the sequence 9,2.5,-4,-10.5,-17
the common difference is negative because we subtract 6.5 to get the next term.
Answer:
The common difference between 9, 2.5, –4, –10.5, –17, ...
Is –6.5
Step-by-step explanation:
Because,
2.5 - 9 = -6.5
-4 - 2.5 = -6.5
-10.5 - (-4) = -6.5
-17 -(-10.5) = -6.5
We can see that the common difference is -6.5
-6.5 is the common difference between successive terms in the sequence 9,2.5,-4,-10.5,-17
the common difference is negative because we subtract 6.5 to get the next term.

4y+2x+30 if x=2and y=5
Answer:
54
Step-by-step explanation:
First let's replace the values x and y.
4y + 2x + 30 will become (4 * 5) + (2 * 2) + 30
Then we do order of operations.
(4 * 5) is 20..
20 + (2 * 2) + 30
Then we do (2 * 2) which is just four.
20 + 4 + 30
Lastly we add it all up.
24 + 30 = 54

Maya is working two summer jobs, making $7 per hour babysitting and $11 per hour landscaping. Last week Maya earned a total of $96 and worked 3 times as many hours babysitting as she worked hours landscaping. Determine the number of hours Maya worked babysitting last week and the number of hours she worked landscaping last week.
Answer:
3 hours for landscaping and 9 hr for babysitting
Step-by-step explanation:
So take x to be babysitting and y to be landscaping
The equation will be 7x+11y=96
$7 for the baby sitting and $11 for the landscaping and 96 for the total
So then it says 3 times as many hours than landscaping so x equation will look like this x=3*y
So replace the terms - 7*(3y)+11y=96
Simplify (7*3)y+11y=96
Simplify more 21y+11y=96
You get 32y=96
Divide both sides by 32 to have y only 32y/32=96/32
You will get y=3
So landscaping will be 3 hours and it says that babysitting is 3 times so multiply 3 you get 9
So landscaping is 3 hours and babysitting is 9 hours
Hope this help
(It may be wrong so if it is im sorry :( )

Anita is filling a small pool for her kids. Currently, there are 60 gallons of water in the pool and she is filling the pool at a rate of 50 gallons every 5 minutes. The pool holds 200 gallons of water.
Which equation represents the amount of minutes (m) that it will take to fill the pool?
-10m + 200 = 60
50m +200 = 60
-10m + 140 = 60
-50m +140=60
Answer:
M/140 = 50/60
Step-by-step explanation:
Since the total is 200 it will be the denominator but we already have 60 gallons so we do 200-60=140
the ratio is 50 per 60

Step-by-step explanation:3.1 minus 5 =-2.1
The required expression will be x = 3.1 n - 5
It is given that a number is 5 less than 3.1 times a number "n" .
We have to find the expression for the given statement.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as multiplication , division , etc.
Let's assume the number be x.
So ,
3.1 times of number n = 3.1 × n = 3.1 n
Let's subtract 5 from the above number, i.e.,
3.1 n - 5
and , the required expression will be ;
x = 3.1 n - 5
Thus , the required expression will be x = 3.1 n - 5

The menu price of a sandwich at a restaurant is $6. The purchase is subject to a 5% food tax, and you would like to leave a tip of 20% on the pre-tax cost. How much tax do you pay? How much of a tip should you leave? What is the total cost of your meal, after tax and tip?
Answer: See explanation
Step-by-step explanation:
Price of sandwich = $6
Food tax = 5% of $6
= 0.05 × $6
= $0.3
Tip = 20% of $6
= 0.2 × $6
= $1.2
Total cost of meal:
= $6 + $0.3 + $1.2
= $7.5
Answer: 1: $0.30 2: $1.20 3: $7.50

[tex]y=-\frac{1}{4} x-1[/tex]
Step-by-step explanation:
[tex]y=mx+b[/tex]
where m = slope, and b = y intercept
The y intercept is -1. That is because the given line intersects the y axis at the point (0,-1)
The slope is -1/4
That is because it goes up one, and right -4. That means it goes up 1 and left 4.
Which set contains the value below?

Answer:
A or d
Step-by-step explanation:a or d
A or d
The set of natural numbers, rational numbers and integers contain 50. Therefore, options B, C and D are the correct answer.
We need to find which set contains the value 50.
What are real numbers?Real numbers include rational numbers like positive and negative integers, fractions, and irrational numbers.
Irrational numbers: Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers.
Here, 50 is not an irrational number.
Rational numbers: A rational number is any number that can be written as a fraction, where both the numerator (the top number) and the denominator (the bottom number) are integers, and the denominator is not equal to zero.
Here, 50=50/1 is a rational number.
Natural numbers: Natural numbers are the numbers that start from 1 and end at infinity.
So, 50 is a natural number.
Integers: An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.
So, 50 is an integer.
The set of natural numbers, rational numbers and integers contain 50. Therefore, options B, C and D are the correct answer.
