Answer:
Each daylilies cost $7
Step-by-step explanation:
Step one:
let roses be x
and daylilies be y
so
8x+15y=193--------------1
also
3x+12y=117--------------2
we can solve equations 1 and 2 by substitution
8x=193-15y
x=(193-15y)/8
put x= (193-15y)/8 in 3x+12y=117
3((193-15y)/8)+12y=117
(579-45y)/8+12y=117
579-45y=8(117-12y)
579-45y=936-96y
collect like terms
579-936=-96y+45y
-357=-51y
divide both sides by -51
y=-357/-51
y=7
Hence each daylilies cost $7
put y=7 in eqn 1
8x+15(7)=193
8x+105=193
8x=193-105
8x=88
x=88/8
x=11
rose cost $8
Help! I'm a little stumped when it comes to variables in matrices. An explanation would be super rad!
What is the determinant of A = [ -2 2 b 0 3 a 0 0 -5 ]
Answer:
30
Step-by-step explanation:
To find the determinant of a 3x3 matrix, you can use this method. (See picture.)
Start with the first number in the top row, and block off the row and column. A 2x2 matrix will be left. Find the determinant of this 2x2 matrix, and multiply it by the number in the top row.
Repeat for the other two numbers in the top row. Add the first result, subtract the second, and add the third.
det A = -2 [(3)(-5) − (a)(0)] − 2 [(0)(-5) − (a)(0)] + b [(0)(0) − (3)(0)]
det A = -2 (3)(-5) − 0 + 0
det A = 30
Solve for G. g+ (-5) = 27
g=
Answer:
G=32 I think,
Step-by-step explanation:
Hope it helps
Answer:
G = 32
Step-by-step explanation:
To do this problem, we first should rewrite the problem.
g + (-5) =27
Turns into
g - 5 = 27.
Then you can do the problem:
g - 5 = 27
+ 5 + 5
----------------
g = 32

Angelo wants to graph the quadratic function shown.
Answer:
c is actually correct lol
Step-by-step explanation:
g(x) = (x-4)(x+2)
set both (x-4) and (x+2) equal to zero
x-4=0
x=4
& bx+2=0
x=-2
c has 4 and -2 as x values

Ben wrestles in the 132 to 138-pound weight class. If he currently weighs 133 pounds, how much weight can he gain if he wishes to stay in the same class?
Answer:
X is less than or equal to 5
Step-by-step explanation:
I cant do the less than or equal to sign so I wrote it in words. Hope this helps :)
Answer:
5 pounds
Step-by-step explanation:
Let x represent Ben's weight gain.
[tex]138 \geq 133 + x\\[/tex]
Subtract 133 from both sides
[tex]5 \geq x[/tex]
Therefore, Ben can't gain more than 5 points if he wishes to stay in the same weight class.

Step-by-step explanation:
In 56 years, Kevin will be 9 times as old as he is right now.
Answer – 7 years old
SOLVINGS
Let Kevin’s present age be ‘x’
In 56 years, Kevin’s age will be x + 56
In 56 years, Kevin’s age will be 9x
Therefore, x + 56 = 9x
Solving for x
x + 56 = 9x
9x – x = 56
8x = 56
x = 56/8
x = 7
Kevin is 7 years old right now.
Here are some letters and what they represent. All costs are in dollars. m represents the cost of a main dish. n represents the number of side dishes. s represents the cost of a side dish. t represents the total cost of a meal. Discuss with a partner: What does each equation mean in this situation? a. M = 7.50
The given question is incomplete
Here are some letters and what they represent. All costs are in dollars.
m represents the cost of a main dish.
n represents the number of side dishes.
s represents the cost of a side dish.
t represents the total cost of a meal.
Discuss with a partner: What does each equation mean in this situation? a. a. m = 7.50
b. m = s + 4.50
c . ns = 6
d. m + ns = t
2. Write a new equation that could be true in this situation.
Answer:
t = 3m -n(s+1)
Step-by-step explanation:
Using the information we can describe the value of each letters
using a and b
we have m = 7.50 and m = s + 4.507.50 = s + 4.50
s = 3
substitute s in c, we get
ns = 6n = 6/3 = 2using equation d we have
m + ns = t7.50 + 6 = tt = 13.50so we an equation using the above data
t +ns = 3m - n
t = 3m -n(s+1)
Zena needs a salesperson. Salesperson A is offering his services for an initial $100 in addition to $5 per hour. Salesperson B is offering her services for $25 per hour. When will the two salespeople charge the same amount of money?
Answer:
Step-by-step explanation:
The correct question is
Zena needs a salesperson. Salesperson A is offering his services for an initial $50 in addition to $5 per hour. salesperson B is offering her services for an initial $40 in addition to $7 per hour. When will the two coaches charge the same amount of money?
Let
x ----> the number of hours
y ----> the total charge
we know that
Salesperson A
------> equation A
Salesperson B
------> equation B
To find out when the two coaches charge the same amount of money, equate equation A and equation B and solve for x

what is the slope of the line below
Answer:
m=1/2
Step-by-step explanation:
When finding the slope of a line on a graph, I like to count the steps up/down and to the side between two of the line's points. For this line, we can see that it has points at (2,-1) and (4,0). To get from (2,-1) to (4,0), you need to count
"up 1, over 2"
1/2
Therefore, the slope is 1/2.

Hurryyy !!! Lincoln Glass pays it workers overtime if they work on weekends or
holidays. Overtime is 1/2 times the usual hourly pay. If Tim was
earning $8.25 an hour, how much would he get for 1 hour of
overtime? For 8 hours of overtime?
Step-by-step explanation:
since overtime is 1/2 the usual pay which is 8.25 or 8 1/4 then its 8 1/4 (divided) by 1/2 which is equal to 4.125 or 4 1/8 so: in 1 hour the workers get paid 4 1/8 dollars and in 8 hours its 8 x 4 1/8 which is equal to 33
really hope this helps :) good luck

Coach De Leon purchases sports equipment. Basketballs cost $20.00 each, and soccer balls cost $18.00 each. He had a budget of $150.00. Part A: Use the drop downs to create an inequality that represent the situation. Let s represent the number of soccer balls and let b represent the number of basketballs. 18s+20b > 150 Part B: Given the coach's budget, which of the following is a viable option for the equipment he can purchase? 4 basketballs and 6 soccer balls 5 basketballs and 2 soccer balls 2 basketballs and 7 soccer balls 6 basketballs and 5 soccer balls
Answer:
5 basketballs and 2 soccer balls
Step-by-step explanation:
5 times 20= 100
2 times 18= 36
equals 136
4 basketballs and 6 soccer balls- wrong-185
2 basketballs and 7 soccer balls-wrong-166
6 basketballs and 5 soccer balls- wrong- over 200
Answer:
The Inequality Equation is
20b + 18s <_ 150
5 Basketballs and 2 Soccer Balls
