Answer:
[tex]x = 18[/tex]
Step-by-step explanation:
Given
[tex]\frac{x}{6} - 7 = -4[/tex]
Required
Solve for x
[tex]\frac{x}{6} - 7 = -4[/tex]
Add 7 to both sides
[tex]\frac{x}{6} - 7+7 = -4+7[/tex]
[tex]\frac{x}{6} = -4+7[/tex]
[tex]\frac{x}{6} = 3[/tex]
Multiply through by 6
[tex]6 * \frac{x}{6} = 3 * 6[/tex]
[tex]x = 3 * 6[/tex]
[tex]x = 18[/tex]

the food pantry distribution 10 oz bags of rice if 3 5 lb bags are donated to the pantry how many 10 ounce bags can be made
Answer:
24 bags can be made from three 5 pounds bags.
Step-by-step explanation:
Given that:
Three 5 pound bags are donated.
Total weight of bags = 3*5 = 15 pounds
We know that:
1 pound = 16 ounces
15 pounds = 16*15 = 240 ounces
A bag weighs 10 ounces.
Number of bags = [tex]\frac{240}{10}[/tex]
Number of bags = 24 bags
Hence,
24 bags can be made from three 5 pounds bags.
aron lei is making identical balloon arrangements for a party. He has 32 maroon balloons and 24 white balloons, he wants each arrangements to have the same number of each color. what is tha greatest number of arrangements that he can make if every balloon is used?
Answer:
The greatest number of arrangements that he can make if every balloon is used is 8.
Step-by-step explanation:
The greatest number of arrangements will be the greatest common factor between 24 and 32.
GCF of 24 and 32:
We keep factoring both numbers by prime factors, while they can both be divided by the same number. So
24 - 32|2
12 - 16|2
6 - 8|2
3 - 4
There is no factor for which we can divide both 3 and 4. So the GCF is 2*2*2 = 8.
This means that the greatest number of arrangements that he can make if every balloon is used is 8.

f) One number is 78 more than
another. If you add 12 to tbe
smaller number, the result is 50.
What is the larger number?
Answer:
The larger number = 116
Step-by-step explanation:
Let the smaller number = x
Given that one number is 78 more than another, so
The larger number = x+78
Given that if we add 12 to the smaller number, the result is 50, so
[tex]x+12=50[/tex]
subtract 12 from both sides
[tex]x+12-12=50-12[/tex]
Simplify
[tex]x=38[/tex]
Therefore,
The smaller number = 38The larger number = x+78 = 38+78 = 116Thus, the larger number = 116
Hello :)
Please help me solve this
Explain answer
Answer:
A. Store A will cost about $1.28 less
Step-by-step explanation:
Store A:
Unit rate = y/x
Using any given pair, say (3, 7.26),
Unit rate = 7.26/3 = $2.42 per gallon
So, of a customer is buying 16 gallons at Store A, he'd pay:
$2.42 * 16 = $38.72
Store B:
Unit rate = y/x
Using any point on the graph, say (20, 50),
Unit rate = 50/20 = $2.5 per gallon
So, of a customer is buying 16 gallons at Store B, he'd pay:
$2.5 * 16 = $40.
Cost of Store B - Cost of Store A = $40 - $38.72 = 1.28
This means that Store A cost about $1.28 less

Find the missing angles.
Answer:
a=30 b=30 c= 75
Step-by-step explanation:
By inferring that all triangles are the same measurments, you can easily knock out A and B since it is the same angle that is labeled 30 degrees.
Now to find C you need to know that all angles of a triangle add up to 180 degrees. You also need to know that both bottom angles are the same angle measurement, indicated by the little circle in the angle.
So, For the middle triangle you can create an equation. 30(which was b) + 2c = 180
Subtract 30 from both sides and you are left with:
2c = 150
Divide by 2 on each side:
c= 75
Solve 3x − 5y = 17
9x − 15y = −4
Answer:
3x - 5y = 17
3(9) - 5(2) = 17
27 - 10 = 17
x = 9
y = 2
---------------------
9x - 15y = -4
I believe this equation has no proper solution. Every "solution" I have found ends with repeating decimals & fractions.
please answer this thank you
Answer:
x = 0,-1,-2,1,2
y = -3,-5,-7,-1,1
(0,-3)
(-1,-5)
(-2,-7)
(1,-1)
(2,1)
Step-by-step explanation:
y = 2x - 3
x = 0,-1,-2,1,2
y = ?,?,?,?,?
x = 0
y = 2x - 3
y = 2(0) - 3
y = 0 - 3
y = -3
x = -1
y = 2x - 3
y = 2(-1) - 3
y = -2 - 3
y = -5
x = -2
y = 2x - 3
y = 2(-2) - 3
y = -4 - 3
y = -7
x = 1
y = 2x - 3
y = 2(1) - 3
y = 2 - 3
y = -1
x = 2
y = 2x - 3
y = 2(2) - 3
y = 4 - 3
y = 1
Check:
x = 0,-1,-2,1,2
y = -3,-5,-7,-1,1
(0,-3)
(-1,-5)
(-2,-7)

I dont know to put for the boxes. When I work the math out I get 5.4 more gallons but I'm confused on what to put for the other boxes
Step-by-step explanation:
One possible solution would be p being the total gallons of paint needed to buy, 250 in the first box (because 250 square feet per gallon), 250 in the second box (because you have 1 gallon = 250 sq. feet leftover) = 1600 (total)

A machine wheel spins at a rate of 500 revolutions per minute. If the wheel has a diameter of 80 centimeters, what is the angular speed of the wheel, in radians per second? Round your answer to the nearest hundredth.
Answer: 3,140 radians per minute.
Step-by-step explanation:
We know that the wheel does 500 revolutions per minute.
This is called the frequency of the wheel, and this is written as:
f = 500 rev/min = 500 RPM
The angular speed (or Angular velocity) is written as
ω = 2*pi*f
And this quantity is in radians/unit of time.
where pi = 3.14
then:
ω = 2*3.14*500 (rev/min)*(rad/rev) = 3,140 rad/min
This means that the angular velocity (or angular speed) is 3,140 radians per minute.

Given:
Multiply: [tex](3x-5)(-x+4)[/tex].
To find:
The simplified product in standard form.
Solution:
We have,
[tex](3x-5)(-x+4)[/tex]
Applying the distributive property, the expression becomes
[tex]=(3x)(-x)+(3x)(4)+(-5)(-x)+(-5)(4)[/tex]
[tex]=(-3x^2)+12x+5x+(-20)[/tex]
On combining like terms, we get
[tex]=-3x^2+(12x+5x)-20[/tex]
[tex]=-3x^2+17x-20[/tex]
Therefore, the simplified product in standard form is [tex]-3x^2+17x-20[/tex].

Find the zeros of y = x2 – 6x – 4 by completing the square.
Answer:
The solutions to the quadratic equations are:
[tex]x=\sqrt{13}+3,\:x=-\sqrt{13}+3[/tex]
Step-by-step explanation:
Given the function
[tex]y\:=\:x^2\:-\:6x\:-\:4[/tex]
substitute y = 0 in the equation to determine the zeros
[tex]0\:=\:x^2\:-\:6x\:-\:4[/tex]
Switch sides
[tex]x^2-6x-4=0[/tex]
Add 4 to both sides
[tex]x^2-6x-4+4=0+4[/tex]
Simplify
[tex]x^2-6x=4[/tex]
Rewrite in the form (x+a)² = b
But, in order to rewrite in the form x²+2ax+a²
Solve for 'a'
2ax = -6x
a = -3
so add a² = (-3)² to both sides
[tex]x^2-6x+\left(-3\right)^2=4+\left(-3\right)^2[/tex]
[tex]x^2-6x+\left(-3\right)^2=13[/tex]
Apply perfect square formula: (a-b)² = a²-2ab+b²
[tex]\left(x-3\right)^2=13[/tex]
[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]
solve
[tex]x-3=\sqrt{13}[/tex]
Add 3 to both sides
[tex]x-3+3=\sqrt{13}+3[/tex]
Simplify
[tex]x=\sqrt{13}+3[/tex]
now solving
[tex]x-3=-\sqrt{13}[/tex]
Add 3 to both sides
[tex]x-3+3=-\sqrt{13}+3[/tex]
Simplify
[tex]x=-\sqrt{13}+3[/tex]
Thus, the solutions to the quadratic equations are:
[tex]x=\sqrt{13}+3,\:x=-\sqrt{13}+3[/tex]
