What is the value of k in the following equation?
2(4k + 5) + 3(3 – 3k) = 25
Answer:
K = - 6
Step-by-step explanation:
Let's solve your equation step-by-step.
2(4k+5)+3(3−3k)=25
Step 1: Simplify both sides of the equation.
2(4k+5)+3(3−3k)=25
(2)(4k)+(2)(5)+(3)(3)+(3)(−3k)=25(Distribute)
8k+10+9+−9k=25
(8k+−9k)+(10+9)=25(Combine Like Terms)
−k+19=25
−k+19=25
Step 2: Subtract 19 from both sides.
−k+19−19=25−19
−k=6
Step 3: Divide both sides by -1.

First 37.50 divided by 3 and that will equal 12.5
second, you need to find out how much 2 games cost so you eithermultiply
12.5 by 2 or add 12.5 two times and you will get 25

Determine if the equation y = 15(1.35)* represents exponential growth or decay and justify. Hint: Think about the growth and decay equations.
Answer:sdfghgfdfghnhgfdfgh
Step-by-step explanatsdfghjhgfghjk
====================================================
Explanation:
The equation is in the form y = a*(b)^x
The 'a' is the initial or starting value. In this case, a = 15.
The b is the base of the exponent which is tied to growth or decay. If 0 < b < 1, then we have decay. If b > 1, then we have growth.
Since b = 1.35, and 1.35 > 1, this means b > 1 and the given equation represents exponential growth.
Solving 1+r = 1.35 leads to r = 0.35. This means the growth rate is 35%

Brenda invited 32 people to her graduation party. If each person will drink about 3 cups of punch, how many gallons of punch does Brenda’s mom need to buy?
How many quarts is this equal to?
Answer:
6 gallons and 24 quarts
Step-by-step explanation:
First, we need to figure out how many cups there are all together. To do this, we do 32*3, which is 96. Now, we can figure out how many gallons 96 cups is equal to. There are 16 cups in one gallon. So, we do 96/16, which is 6. This means that she will need 6 gallons of punch at her party. There are 4 quarts in one gallon. To find how many quarts are in six gallons, we do 4*6, which is 24. There are 24 quarts in six gallons.
Answer:
6 gallons and 24 quarts

A local ice cream shop sells root beer floats for $2.75 and milkshakes for $6. One day the shop sold 10 more root beer floats than milkshakes and made $290. How many root beer floats were sold on this day? How many milkshakes?
Answer:
30 milkshakes and 40 root beer floats
Step-by-step explanation:
Set up a system of equation (r is root beer and m is milkshake)
2.75r+6m=290
m+10=r
Substitute
2.75(m+10)+6m=290
2.75m+27.5+6m=290
8.75m=262.5
m=30
Now plug in 30 and solve for r
30+10=40

A model rocket is launched directly upward at a speed of 28 meters per second from a height of 12 meters. The function f(t) = - 4.9t ^ 2 + 28t + 12, mo models the relationship between the height of the rocket and the time after launch. in seconds When seconds after launch will the rocket hit the ground? Do not round until the final answer. Then round your answer to two decimal places. Provide your answer below:
Answer:
6.11 seconds
Step-by-step explanation:
Given
[tex]f(t) = -4.9t^2 + 28t + 12[/tex]
Required
When will it hit the ground?
When it hits the ground, f(t) = 0.
So, we have:
[tex]0 = -4.9t^2 + 28t + 12[/tex]
Solve quadratic equation using formula
[tex]t = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]t = \frac{-28 \± \sqrt{28^2 - 4*-4.9*12}}{2*-4.9}[/tex]
[tex]t = \frac{-28 \± \sqrt{1019.2}}{-9.8}[/tex]
[tex]t = \frac{-28 \± 31.92}{-9.8}[/tex]
Split
[tex]t = \frac{-28 + 31.92}{-9.8}[/tex] or [tex]t = \frac{-28 - 31.92}{-9.8}[/tex]
[tex]t = \frac{3.92}{-9.8}[/tex] or [tex]t = \frac{-59.92}{-9.8}[/tex]
[tex]t = -0.4[/tex] or [tex]t = 6.11[/tex]
Time can not be negative. So:
[tex]t = 6.11[/tex]

carlos is planting a vegetable garden. He has 30 carrot seeds, 24 tomato seeds, and 36 lettuce seeds. Each row will have the same number of seeds, but carrots, tomatoes and lettuce will not appear in the same row. If he puts the greatest possible number of seeds in each row how many rows will there be?
Answer: 15
Step-by-step explanation:
The GCF of 30, 24, and 36 is 6. 30 divided by 6 is 5, 24 divided by 6 is 4, and 36 divided by 6 is 6. 5+4+6=15
The number of rows when he puts the greatest possible number of seeds should be considered as 15.
Calculation of the number of rows:Since
He has 30 carrot seeds, 24 tomato seeds, and 36 lettuce seeds.
So
The GCF of 30, 24, and 36 is 6.
Now we have 30 that should be divided by 6 is 5,
And, 24 divided by 6 is 4,
and 36 divided by 6 is 6
So the no of rows should be
= 5+4+6
=15

Which expression is equivalent to f(x)=6x^2-13x+5
Answer:
(3x - 5)(2x - 1)
Step-by-step explanation:
6x² - 13x + 5
6x² - (10 + 3)x + 5
6x² - 10x - 3x + 5
2x(3x - 5) - (3x - 5)
(3x - 5)(2x - 1)
Which means, 6x² - 13x + 5 is equivalent to (3x - 5)(2x - 1) or vice versa
