0.75 (x + 16) = 3 – 0.5 (x-8)
Answer:
x= 18.29
Step-by-step explanation:
- distribute then simplify- .75x + 12 = 2.5x - 20
- subtract .75x from each side- 12 = 1.75x - 20
- add 20 on each side- 32 = 1.75x
- divide each side by 1.75x- x= 18.29
not 100% sire if thats correct
[tex]0.75\left(x+16\right)=3-0.5\left(x-8\right)[/tex]
[tex]0.75\left(x+16\right)\cdot \:100=3\cdot \:100-0.5\left(x-8\right)\cdot \:100[/tex]
[tex]75\left(x+16\right)=300-50\left(x-8\right)[/tex]
[tex]75x+1200=-50x+700[/tex]
[tex]5x+1200-1200=-50x+700-1200[/tex]
[tex]75x=-50x-500[/tex]
[tex]75x+50x=-50x-500+50x[/tex]
[tex]125x=-500[/tex]
[tex]\frac{125x}{125}=\frac{-500}{125}[/tex]

The picture says it all ty! <3
Answer:
only Katie is right
Step-by-step explanation:
first, find the nth rule using the equation n = a + (n - 1)d
a = first term (here, it's 22)
n = the position of a term
d = the constant difference between each term (here, it's -5 since each term reduces by 5)
put these in and then simplify:
n = a + (n - 1)d
n = 22 + (n - 1)(-5)
n = 22 - 5n + 5
n = -5n + 27
this can be rewritten as n = 27 - 5n, which means therefore that only Katie is right. hope this helps!
Answer: Only Katie
Reason: Only Katie is correct!

Carlos is a member of a gym. He pays a monthly fee plus a per- visit fee. The equation y = 3x + 10 represents the monthly amount Carlos pays for x visits.
if Carlos pays $85 in the last month how many times did he visit the gym?
Answer:
25 times
Step-by-step explanation:
To find how many times he visited, plug in 85 as y and solve for x:
y = 3x + 10
85 = 3x + 10
75 = 3x
25 = x
So, Carlos visited the gym 25 times

1). what is the area of the rectangle whose length is (x+5) and width (x-5)?
Answer:
[tex]x^{2}[/tex]-25
Step-by-step explanation:
formula for areas of rectangles= width x height
width=x-5
height=x+5
(x-5)(x+5)= [tex]x^{2}[/tex]-5x+5x-25
since the 5x's cancel out each other
=[tex]x^{2}[/tex]-25 will be the answer
The area of rectangle is [tex](x^{2} -25)[/tex] unit square.
The area of rectangle is product of length and width.
[tex]Area = length*width[/tex]
Given that length is [tex](x+5)[/tex] and width is [tex](x-5)[/tex].
[tex]Area=(x+5)*(x-5)\\\\Area=x^{2} -5x+5x-25=x^{2} -25[/tex]
Hence, the area of rectangle is [tex](x^{2} -25)[/tex] unit square.

Answer: No, the scenario won't earn you enough money
====================================================
Explanation:
You work 4 hours with your uncle, at $8 an hour, so that means you earn 4*8 = 32 dollars.
You work 12 hours online, at $4 an hour, so you earn 12*4 = 48 dollars.
In total, you earn 32+48 = 80 dollars overall when combining the two lines of work.
The total 80 is smaller than 120, so this scenario isn't possible if you want to aim for $120 or more. You'll need to work more hours somehow.
Find the missing length.
Answer:
Triangle 1 - 4
Triangle 2 - 10
Step-by-step explanation:
To find the missing side lengths of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem states that: a² + b² = c². In this equation, a and b are legs, and c is the hypotenuse.
Using this to solve triangle 1, you get the equation: a² + 3² = 5² or a² + 9 = 25. To solve for a², you subtract 9 from both sides to get a² = 16. To solve for a, find the square root of 16, which is 4.
Using the Pythagorean Theorem to solve for triangle 2, you get the equation: 6² + 8² = c² or 36 + 64 = c². Add 36 + 64 to get 100 = c². Find the square root of 100 to solve for c. The square root is 10.

feet per minute.
Bob's linear speed is higher than Jack's because the radius of the circle
around which Bob rotates is larger.
Responses:
Jack's linear speed is approximately 377 feet per minuteBob's linear speed is approximately 527.8 feet per minuteWhat is the relationship between linear speed and angular speed?Given:
The rotational speed of the merry go round = 6 revolution per minute
Jack's distance from the center = 10 feet
Bob's distance from the center = 14 feet
The angular speed, ω, of the merry-go-round is found as follows;
[tex]\omega = \mathbf{\dfrac{6 \times 2 \cdot \pi}{1 \ minute}} = 12 \cdot \pi \ rad/minute[/tex]Linear speed = ω × rWhich gives;
Jack's linear speed = 12·π rad/min × 10 feet ≈ 377 feet per minuteBob's linear speed = 12·π rad/min × 14 feet ≈ 527.8 feet per minuteLearn more about angular speed and linear speed here:
