Amanda has $40 to spend on flowers. She wants to buy a pair of red rose flowers for $18 and spend the rest on lly flowers. Each lily flower costs $11. Choose the inequality for the number of lly
flowers she can purchase:
o
A
11x + 18 5 40
B. 18x + 11 S 40
G
C. 11x + 18 < 40
D. 18x + 18 < 40
Answer:
[tex]11x + 18 \leq 40[/tex]
Step-by-step explanation:
She can buy x illy flowers, and each illy flower costs $11.
She wants to buy a pair of red rose flowers for $18 and spend the rest on lly flowers. Each lily flower costs $11.
This means that the total amount she will spend is:
[tex]18 + 11x[/tex]
Amanda has $40 to spend on flowers.
This means that her total spending can be at most $40, which means that:
[tex]11x + 18 \leq 40[/tex]
This is the inequality that models this situation.

James has collected 3985 stamps so far. He had 787 stamps from countries other than the United States. What percent of the stamps are from countries other than the United States?
Answer:
divide 787 by 3985 then multiply that by 100
Step-by-step explanation:
if it were 100 stamps total and 50 from non US countries, you could pretty easily tell it was half, or 50% to ge that you need to divide the number in question by the total so 50/100. which gets .5. to get the percent you multiply it by 100
so given the numbers we divide 787 by 3985 then multiply that by 100

Anna has 15 blue blocks, 18 red blocks, 15 green blocks, and 21 yellow blocks. She has 69 blocks altogether
What is the ratio of red to yellow
A) 6 to 7
B) 6 to 23
C) 5 to 7
D) 5 to 6
Answer:
A 6 to 7
Step-by-step explanation:
18 divided by 3 is 6
21 divided by 3 is 7
Answer:
A. 6 to 7
Step-by-step explanation:
18 : 21 then you simplify
6 : 7

i) For an given A.P. t7
= 4, d = -4 then a = . . .
Answer:
a = 28
Step-by-step explanation:
Given : t7= 4 , d = -4
Solution : tn = a + (n - 1) d ......( formula)
t7 = a + (7 - 1) (-4)
4 = a + (6)( - 4)
4 = a - 24
4 + 24 = a
28 = a
therefore, the first term (a) is 28.
If you have $3250 how many board feet can you buy if the cost per board foot is $2.29?
Answer:
If i am right i think its 1419
Step-by-step explanation:
3250/2.29= about 1419
Answer:
1419.21= 1419
Step-by-step explanation:
Divide the amount of money you have with the cost price of what you want to buy.
$3250/$2.29=1419.213974
The answer is a decimal. But we can not have a unit as decimal so we have to round it down to the nearest whole number.
Therefore = 1419
Find the values of x and y in parallelogram PQRS. PT=y, TR=4x+1, QT=2y, TS=3x+12 In parallelogram PQRS, diagonals PR and QS cross at point T. Q P S R T x=nothing and y=nothing
Here is my answer. I hope this is helpful.
The required values of x and y are x = -2 and y = 7 in parallelogram PQRS.
How to find the values of x and y?To find the values of x and y, we can use the fact that the diagonals of a parallelogram bisect each other. This means that the line segment PT is equal to half of the diagonal PR, and the line segment QT is equal to half of the diagonal QS.
We can set up two equations to represent this information:
PT = 1/2 × PR
QT = 1/2 × QS
Since we are given the lengths of PT and QT, we can substitute those values into the equations:
y = 1/2 × PR
2y = 1/2 × QS
We can then use the fact that the opposite sides of a parallelogram have equal lengths to find the values of PR and QS:
PR = PT + TR = y + (4x + 1)
QS = QT + TS = 2y + (3x + 12)
Substituting these values into the equations above, we get:
y = 1/2 × (y + (4x + 1))
2y = 1/2 × (2y + (3x + 12))
Solving these equations simultaneously will give us the values of x and y.
First, we can solve the second equation for y:
y = (1/2) × (2y + (3x + 12))
y = y + (3x + 12)/2
0 = 3x + 12/2
0 = 3x + 6
-6 = 3x
x = -2
Substituting this value of x into the first equation, we can solve for y:
y = 1/2 * (y + (-2 * 4 + 1))
y = 1/2 * (y - 7)
2y = y - 7
y = 7
Therefore, the values of x and y are x = -2 and y = 7.

Least the containers from least to greatest capacity; 1.73, 2.061, 1.59, 2.1
Answer:
1.59 < 1.73 < 2.061 < 2.1
Step-by-step explanation:
Hello,
We know that 2 is higher than 1. So to pick the first ones we know it won't be the two numbers starting with a 2. We are left with two numbers : 1.73 and 1.59. In this case we can multiply these two numbers by 100. We are allowed to do this only if we do it to all the numbers we are trying to figure out. In this case, it is 1.73 and 1.59 (we are excluding the 2s). So we end up with : 173 and 159. This might help you. We obviously know that 173 is a larger number than 159.
So, we then proceed to the numbers starting with a 2. In this case we can multiply both by 1,000 considering the fact that the number 2.061 has 3 digits after the dot. This will make it easier for us. When we multiply both by 1,000 we end up with 2,061 and 2,100. We obviously know that 2,061 is smaller than 2,100.
I hope this helped
