Your friend really wants to buy the newest cell phone which will cost him $750. He gets a job detailing cars and SUVs and plans to save all the money he earns. If he gets paid $55 to detail a car and $70 to detail an SUV, what linear inequality can be used to determine how many of each he must detail in order to earn at least $750?
A: 55c+70x [tex]\leq[/tex] 750
B: 55c+70x > 750
C: 55c+70x [tex]\geq[/tex] 750
D: 55c+70x < 750
Answer:
C, 55c + 70x ≥ 750
Step-by-step explanation:
He needs a minimum of $750.
The equation 55c + 70x 750 can be used to calculate how many of each he needs detail in order to make at least $750. The right answer is A.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
Given that,
Number of cars = c
Number of SUVs = x
Amount paid for detailed car = $55
Amount paid for detailed SUV = $70
Cost of coolest cellphone = $750
The inequality for the given data will be written as below,
(Amount paid for detailed car × Number of cars) + (Amount paid for detailed SUV × Number of SUV) ≤ Cost of coolest cellphone
55c + 70x ≤ 750
Therefore, the equation 55c + 70x 750 can be used to calculate how many of each he needs detail in order to make at least $750. The right answer is A.

b = 9
c = 9
Step 3: Solve for x

C. x= 2
O D. x= 6
SUBMI
Answer:
Think
Step-by-step explanation:
4x - 6 + 2x = 18
You are solving for x so obviously you have to have your x variable on one side of the equal sign by itself.
So how do you do that? Combine the same calues together and seperate the rest
4x + 2x = 6x
6x = 18 + 6
6x = 24
x = 3
Practice practice practice. Simple stuff. You got this!
Answer:
A. x = 4
Step-by-step explanation:
To answer this question, we first have to combine like terms:
4x - 6 + 2x = 18
6x - 6 = 18
Now, we take away 6 from the left side and add it to the right side:
6x - 6 = 18
+6 +6
6x = 24
Then, we isolate the variable:
6x = 24
/6 /6
x = 4

There were 28 boys on the boy's basketball team and 16 girls on the girl's basketball team last year. This year the number of boys decreased by 8% but the number of girls increased by 19%. Was there an increase or decrease in overall participation?
There is an increase in total participants.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
number of boys = 28
Number of girls = 16
Total participants = 28 + 16 = 44
Now, there is decrease in number of boys by 8%
= 28- 8% x 28
=28- 8/100 x 28
=28 - 0.08*28
=28 -2.24
= 25.76
and, there is 19% increase in number of girls
=16 + 0.19 x 16
=16 + 3.04
=19.04
So, total participants = 25.76 + 19.04
= 44.8
Hence, there is an increase in total participants.

We can tell that the whole L shaped angle is 90 degrees because it has the little box in the corner. Now, the 90 degree angle is split into two parts with that line coming from the box. Those two parts of the whole 90 degree angle add up to 90 degrees.
90 = 4v + 2 + 9v - 3
Now, let's solve for v. Combine like terms.
90 = 13v - 1
Add 1 to both sides.
91 = 13v
Divide both sides by 13
7 = v

Okay, let's define what a circumference is.
Circumference - The entire outside of a circle, think of it as the "perimeter" of the circle, like how there is a perimeter for a triangle or square.
The equation for finding the circumference is as follows:
[tex]2\pi r[/tex]
r - the radius, or half-way line is a circle.
So, you see the number thats on a half way line in the circle? That is the radius. All you have to do is plug in that number into the equation (for r), and you get the answer.
#3
r = 15
[tex]2\pi (15) = 30\pi \\[/tex]
Now use a calculator and type in 30, then times it by pi (which is this symbol: [tex]\pi[/tex])
Circumference = 94.248
#4
r = 10
[tex]2\pi (10) = 20\pi \\[/tex]
Circumference = 62.832

Amy sold 10 t-shirts and 2 sweatshirts for $56.
Adam sold 5 t-shirts and 3 sweatshirts for $48.
Write a system of equations to represent this
situation. Let x=cost of a t-shirt and y=cost of a
sweatshirt.
Determine the price of one t-shirt and the price
of one sweatshirt.
Answer:
$3.6 = cost of a t-shirt
$10 = cost of a sweatshirt
Step-by-step explanation:
Given:
10 t-shirts and 2 sweatshirts = $56.
5 t-shirts and 3 sweatshirts = $48.
x = cost of a t-shirt
y = cost of a sweatshirt
Find:
Price
Computation:
10x + 2y = 56.......eq1
5x + 3y = 48........eq2
From 2 x eq2
10x + 6y = 96.........eq3
From eq3 - eq1
4y = 40
y = 10
from eq1
10x + 2(10) = 56
10x + 20 = 56
10x = 36
x = 3.6
$3.6 = cost of a t-shirt
$10 = cost of a sweatshirt
