Answer:
Step-by-step explanation:
Acme Company:
Let the number of shirts = x
Cost = 50 + 9x
Beta Company:
Cost = 14x
50 + 9x < 14x
Subtract 9x from both sides
50 < 14x - 9x
50 < 5x
Divide both sides by 5
50/5 < x
10 < x
Minimum number of shirts for which a customer saves money by using Acme = 11 T-shirts

How would I simplify this expression
Answer:
-3 - 16b
Step-by-step explanation:
by simply doing the multiplication and then add combinable terms.
9 - 4(3 + 4b) = 9 - 12 - 16b = -3 - 16b
Explanation:
Let's simplify step-by-step:
9-4(3 + 4b)
Distribute:
= 9 + (-4)(3) + (-4)(4b)
= 9 + (-12) + (-16b)
Combine Like Terms:
= 9 + (-12) + (-16b)
= (-16b) +(9 + (–12) )
= -16b + (-3)
Answer:
-16b + (-3)

wrie down the equation of the line that is parallel to 4x - 2y = 7 and passes through (9, -3)
Answer:
4x-2y =42 is the required equation
Step-by-step explanation:
given equation is,
4x-2y -7=0---------eqn1
parallel equation of given equation is
4x -2y+k =0-------eqn 2
now passing it through (9,-3), we get,
4×9 + 2×3 +k = 0
or,36+6+k =0
or,42+k =0
or, k= -42
putting the value of k in eqn2
4x-2y - 42=0
4x-2y = 42

Find the length of the arc
Answer:
C
Step-by-step explanation:
There are two arcs a major and a minor arc. You should never have to rely on a diagram to get the right answer.
The circumference is 2 * pi * r
r = 6 km
C = 2* pi * 6
C = 12 pi
The arc size is
arc size = 135 / 360 * 12pi
arc size = 3/8 * 12 pi
arc size = 4 1/2 pi = 9 pi /2 km

Addition can be defined as the process of adding two numbers. The two integers with different signs that have a sum of -28 are -29 and 1.
What is Addition?Addition can be defined as the process of adding two numbers such that the result is the combined value of the two numbers.
An integer is a number that can be written without using a fractional component.
Given that the two integers with different signs have a sum of -28. Therefore, we can write,
-29 + 1 = -28-30 + 2 = -28-31 + 3 = -28-32 + 4 = -28-33 + 5 = -28-34 + 6 = -28-35 + 7 = -28Hence, the two integers with different signs that have a sum of -28 are -29 and 1.

Xian and his cousin Kal both collect stamps. Xian has 52 stamps, and Kal has 68 stamps. The boys recently
joined different stamp-collecting dubs. Xian's club will send him 20 new stamps per month. Kai's club will
send him 16 new stamps per month. After how many months will Xlan and Kal have the same number of
stamps? How many stamps will each have?
Answer:
In 4 months, they will both have 132 stamps.
Step-by-step explanation:
Let x = # of months
52 + 20x = 68 + 16x
4x = 16
x = 4
Plug x value into both expressions and see if it checks out
52 + 20(4) = 68 + 16(4)
52 + 80 = 68 + 64
132 = 132
EMERGENCY A speeding ticket costs $80 plus $10 for each mile per hour over the speed limit the violator was traveling. How much would someone going 12 miles per hour faster than the speed limit have to pay for their ticket?
Answer:
$200
Step-by-step explanation:
Fine calculated per mile = $10
Fine calculated for 'm' mile = 10 * m = 10m
Cost paid by violator = 80 + 10m
m = 12 miles
Cost paid by the violator = 80 + 10*12
= 80 + 120
= $ 200

Solve for the value of k
Answer:
4k-7 + 3k+ 6 = 90
7k -1 = 90
7k = 91
k=13
Step-by-step explanation:
Notice that if we add the 3 angles in the image, the outcome should be an angle of 180° (the one of the line alone)
With this, we will found that the answer is k = 13
Let's do the math, for the initial information we can write:
(4k - 7)° + 90° + (3k + 6°) = 180°
Where the 90° comes from the right angle, the one written with a little square.
Now we can solve this for k
(4k - 7)° + 90° + (3k + 6°) = 180°
(4k + 3k)° + (-7° + 90° + 6°) = 180°
7°k + 89° = 180°
7°k = 180° - 89° = 91°
k = 91°/7° = 13
So we found that the value of k is 13.

I’m confused on the subtraction behind the one, am I supposed to turn the one into a negative?
1-(4+3x)<-3
Answer:
x>0
Answer to your question:
Because the subtraction sign is after the negative, it applies to the term in front of it, in this case because there is a parenthesis, it would multiply into that and your equation from there would be 1-4-3x<-3. Then combine like terms from there.

The area of a campground is exactly halfway between 25.9 acres and 26 acres . What is the area of the compound?
We have an algebra problem. Here we want to find the mid-value between 25.9 acres and 26 acres, we will find that the area of the compound is 25.95 acres.
For two given numbers A and B, such that A < B, the mid-value between these is given by:
A + (B - A)/2.
In this case, our two numbers are 25.9 and 26.
Using the above formula we get:
25.9 + (26 - 25.9)/2 = 25.95
Then we can conclude that the area of the compound is 25.95 acres.

if angle c=60° , b=5 ,a=4 then find the value of the c ?
Answer:
c=sqrt21
Step-by-step explanation:
angle c is the angle between a and b, so use the cos law

a.a + b.b = 612
And
a+b = 30
so a.b?
Pls help.
Answer:
ab = 144
Step-by-step explanation:
Assuming you mean a² + b² = 612, then
(a + b)² = a² + 2ab + b² , that is
30² = a² + 2ab + b² , so
a² + 2ab + b² = 900
a² + b² + 2ab = 900 ← substitute a² + b² = 612
612 + 2ab = 900 ( subtract 612 from both sides )
2ab = 288 ( divide both sides by 2 )
ab = 144
