4. Harry is going to send some flowers to his wife. Summerfield Florist charges $1 per rose, plus
$39 for the vase. Grayson’s Flowers, in contrast, charges $3 per rose and $15 for the vase. If
Harry orders the bouquet with a certain number of roses, the cost will be the same with either
flower shop. How many roses would there be? What would the total cost be?
The number of roses purchased will be; 12 roses
The total cost of the bouquet is; $51
Let number of roses be x
For Summerfield florists;
At $1 per rose and $39 for the vase, cost is;
C = x + 39
For grayson's flowers;
At $3 per rose and $15 for the vase,total cost is;
C = 3x + 15
We are told when he orders a certain number of roses, the cost will be the same with each flower shop.
Thus;
x + 39 = 3x + 15
3x - x = 39 - 15
2x = 24
x = 24/2
x = 12
Total cost is;
C = 12 + 39
C = $51

Answer:
7.5 hours
Step-by-step explanation:
y=mx+b, where y is cost and x is hours.
175 = 20x + 25

7.5 = x
He worked 7.5 hours
The number line shows the graph of an inequality:
A number line is shown from negative 5 to positive 5 with increments of 0.5. All the whole numbers are labeled on the number line. An empty circle is shown on the seventh mark to the left of 0. The region to the left of the empty circle is shaded.
Which statement explains whether −4.5 can be a value in the shaded region? (5 points)
No, it cannot because −4.5 lies to the left of −3.5.
No, it cannot because −4.5 lies to the right of −3.5.
Yes, it can, because −4.5 lies to the right of −3.5.
Yes, it can, because −4.5 lies to the left of −3.5.
If you get the best answer I will mark you as brinitlylist
if 2 people answer
Answer:
Yes, it can, because -4.5 lies to the left of -3.5
Step-by-step explanation:
we know that
The solution of the inequality is equal to the interval------> (-∞,-3.5)
All real numbers less than -3.5
x<-3.5
Substitute in the inequality
-4.5<-3.5 ------> is true
therefore
The number -4.5 is a value in the shaded region, because lies to the left of -3.5

Abigail’s family was going on vacation. They decided to rent a jet ski. When they went to rent the jet ski, they had to pay a $40 deposit and then $35 an hour.
Which equation could be used to calculate how many hours they rented the jet ski if they ended up paying a total of $145.
A. 145 + 35x = 40
B. 35x = 145 + 40
C. 35x - 40 = 145
D. 40 + 35x = 145
Answer:
The Answer To This Question Is D.
Step-by-step explanation:
So they had to pay 40 and then 35 an hour = 40 + 35x = 145

What is the slope of the line that passes through the points (-2, -5)(−2,−5) and (-3, -6) ?(−3,−6)? Write your answer in simplest form.
Answer:
0 & 0
Step-by-step explanation:
In order to find the answer to these two questions you need to use the slope formula, substitute, subtract, and simplify if needed.
[tex](-2,-5),(-2,-5) = (x^1,y^1),(x^2,y^2)[/tex]
Slope formula = [tex]m=\frac{y^2-y^1}{x^2-x^1}[/tex]
Substitute: [tex]\frac{-5--5}{-2--2} =[/tex]

Which is one solution, no solution, and infinite solutions?
3(4x-2) = 12x - 6
3(4x-2)= -12x - 6
-3(4x-2) = -12x - 2
Step-by-step explanation:
3(4x - 2) = 12x - 6
12x - 6 = 12x - 6
that is always true, no matter what value we pick for x.
so, this has infinite many solutions.
3(4x - 2) = -12x - 6
12x - 6 = -12x - 6
24x = 0
x = 0
this has one solution.
-3(4x - 2) = -12x - 2
-12x - 6 = -12x - 2
-6 = -2
this is never true, no matter what value we pick for x.
so, this has no solution at all.
Answer:
see below
Step-by-step explanation:
Hi!!
Here's how I found it:
First, I simplified all my equations.
1.12x-6=12x-6
2.12x-6=-12x-6
3.-12x+6=-12x-2
#1 has infinite solutions, given that the equations are identical to eachother. Any value of x will sufice.
#2 can be simplifed with algebra.
Cancel out the -6, since it is on both sides.
we are left with 12x=-12x, which can be solved with the value of 0. This has one solution.
#3 can also be simplifed using algebra.
Cancel out the -12x, since both sides have that.
you are left with:
6=-2
this will never have a solution, therefor, it is no solution.

A computer and printer cost a total of $930 . The cost of the computer is two times the cost of the printer. Find the cost of each item.
Answer:
Computer: $620
Printer: $310
Step-by-step explanation:
c + p = 930
c = 2p
c = cost of the computer
p = cost of the printer
replacing the second eq. in the first eq.
2p + p = 930
3p = 930
p = 930/3
p = 310
from the second eq.
c = 2p
c = 2*310
c = 620
Check
from the first eq.
620 + 310 = 930
Eli is now one quarter of his father’s age. In 5 years’ time his age will be one third of
his father’s age. How old is Eli now?
Answer:
10
Step-by-step explanation:
This is because 10×4=40
10+5=15
40+5=45
45/15=3
Answer:
Step-by-step explanation:
Let E and F represent Eli and his Father's current ages.
We are told that E = (1/4)F. ["Eli is now one quarter of his father’s age"]
But in 5 years, that will be:
(E+5) = (1/3)(F+5) ["In 5 years’ time his age will be one third of
his father’s age"]
-------------
We have two equations and two unknowns. Find a way to eliminate one of the two variables and then solve for the remaining variable.
E = (1/4)F
(E+5) = (1/3)(F+5)
It seems to me the easiest would be to use the first equation's definition of E [=(1/4)F] in the second equation:
(E+5) = (1/3)(F+5)
((1/4)F+5) = (1/3)(F+5)
(1/4)F - (1/3)F = (1/3)*5 - 5
F - (4/3)F = (4/3)*5 - 20
-(1/3)F = (20/3) - (60/3)
-(1/3)F = (-40/3)
F = (120/3)
F = 40 years
E = 10 years (based on E = (1/4)F)
====
In five years: F is 45 and E is 15, which would make Eli 1/3 of his father's age in 5 years.

Answer:
√85
Step-by-step explanation:
The distance formula is used for this purpose.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((3 -5)² +(5 -(-4))²) = √((-2)² +9²) = √(4 +81)
d = √85 . . . . the distance between the two points

Hey there!
(ab + 3c)^2
= (ab + 3c)(ab + 3c)

what is the answer -v+91=261
Answer:
v = -170
Step-by-step explanation:
-v + 91 = 261
(-v + 91) - 91 = 261 - 91
-v = 170
-v / -1 = 170 / -1
v = -170
Step-by-step explanation:
(-v) +91 = 261
(-v) =91=261
(-v)=261-91
(-v)=170
v= - 170 (change the signs)
