-46 - 8x > 22
Step 2: Solve for x
[Addition Property of Equality] Add 46 on both sides: -8x > 68[Division Property of Equality] Divide -8 on both sides: x < -17/2Answer: x < −17/2
Step-by-step explanation:
Let's solve your inequality step-by-step.
−46 − 8x > 22
Step 1: Simplify both sides of the inequality.
−8x − 46 > 22
Step 2: Add 46 to both sides.
−8x − 46 + 46 > 22 + 46
−8x > 68
Step 3: Divide both sides by -8.
−8x/−8 > 68/−8
x < −17/2

There's a piece of a pyramid is a rectangle with a width of 4.6 cm and the length of the 9 cm. What is the height in centimeters of the pyramid if it's volume is 82.8 cm^3
Answer:
6cm
Step-by-step explanation:
Given data
Width= 4.6cm
Length= 9cm
Volume= 82.8cm^3
The expression for the volume is given as
V= lwh/3
82.8= 9*4.6*h/3
cross multiply
82.8*3= 9*4.6*h
248.4= 41.4h
h= 248.4/41.4
h= 6cm

5x - y = -1 - -5x + 3y = 25
Answer:
x = 101/20, y = 1/4
Step-by-step explanation:
Solve the following system:
{-y + 5 x = 25 | (equation 1)
3 y + 5 x - 1 = 25 | (equation 2)
Express the system in standard form:
{5 x - y = 25 | (equation 1)
5 x + 3 y = 26 | (equation 2)
Subtract equation 1 from equation 2:
{5 x - y = 25 | (equation 1)
0 x+4 y = 1 | (equation 2)
Divide equation 2 by 4:
{5 x - y = 25 | (equation 1)
0 x+y = 1/4 | (equation 2)
Add equation 2 to equation 1:
{5 x+0 y = 101/4 | (equation 1)
0 x+y = 1/4 | (equation 2)
Divide equation 1 by 5:
{x+0 y = 101/20 | (equation 1)
0 x+y = 1/4 | (equation 2)
Collect results:
Answer: {x = 101/20, y = 1/4

Answer:
6.11 ft
Step-by-step explanation:

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 63 N acts on a certain object, the acceleration of the object is 7 /ms2. If the acceleration of the object becomes 2nd /ms2, what is the force?
Answer:
18 N
Step-by-step explanation:
Let F denote the force, m denote the mass of the object and a denote the acceleration of the object.
[tex]F=ma[/tex]
[tex]m = \frac{F_{1} }{a_{1} }=\frac{63}{7} =9 kg[/tex]
[tex]F_{2} =ma_{2}=9*2=18N[/tex]
The value
Pi /2
is a solution for the equation 2 sin^2 x- sin x-1=0.
O A. True
B. False
Answer:
A
Step-by-step explanation:
Check the solution by substituting x = [tex]\frac{\pi }{2}[/tex] into the left side of the equation
2sin²x - sinx - 1
= 2sin²([tex]\frac{\pi }{2}[/tex] ) - sin ([tex]\frac{\pi }{2}[/tex] ) - 1
= 2(1)² - 1 - 1
= 2 - 1 - 1
= 0
= right side
[tex]\frac{\pi }{2}[/tex] is therefore a solution to the equation

heyo, algebra is giving me a headache, help me with this pls?
Answer:
H: 41
Step-by-step explanation:
upfront charge = 36
each cone costs .52
sell price 1.40
(sell price - cone cost) * number of cones - upfront cost =0 to find where break even is
-36+(1.40-.52)*x=0
-36+.88x=0
.88x=36
x=40.90
need to round up to break even to 41
Answer:
Option C 41 is correct answer.
Given:
Cost of rent of the equipment = 36 $
Cost on ingredients of each cone = 0.52 $
Selling price of each cone = 1.40
To find:
Number of cones(let = x) joel must sell in order to make a profit?
1.40x > 36+ 0.52x
subtracting 0.52 x from both the side,
1.40x - 0.52x > 36
0.88x > 36
dividing both side by 0.88,
x > 36/0.88
x> 40.909090....~ 41
Option C 41 is correct answer.

A sequence is defined recursively by the formula f(n + 1) = –2f(n). The first term of the sequence is –1.5. What is the next term in the sequence?
–3.5
–3
0.5
3
Answer:
The answer is 3
Step-by-step explanation:
It's just wisdom I mean think about it it
1.5 then 3
⭐ Initially, we have to find the reason why it was -1.5:
[tex]\large {\text {$ \sf f (n+1) = -2 f(n) $}}[/tex]
➡️ Having n, then we'll find the value of n, then we'll replace it with the found result.
[tex]\large {\text {$ \sf f (x+1) = -2.x = -1,5 $}}[/tex]
⌛ So, we will have to find what x is worth in this case:
[tex]\large {\text {$ \sf f ( 0,75 +1 ) = -2 \cdot 0,75 $}}[/tex]
[tex]\large {\text {$ \sf f ( 0,75) = -1,5 $}}[/tex]
→ Knowing this...
[tex]\large {\text {$ \sf f ( 1,5 + 1 ) = -2 \cdot 1,5 $}}[/tex]
[tex]\large {\boxed {\boxed {\sf f ( 2,5 ) = -3 }}}[/tex] [tex]\checkmark[/tex]

Rachel has two coupons for a bicycle.
Coupon A:
15% off of a $95 bicycle
$18 rebate on a $95 bicycle
Coupon B:
Choose the coupon that gives the lower price.
Then fill in the blank with the correct value.
Coupon A gives the lower price.
Х
The price with coupon A is $(less than the price with coupon B.
Coupon B gives the lower price.
The price with coupon B is $ less than the price with coupon A.
$
Answer: Coupon B gives the lower price
The price of coupon B is 3.75 dollars less than the price of coupon A.
======================================================
Explanation:
15% off means she saves 15% of the original price.
15% of 95 = 0.15*95 = 14.25
Rachel saves $14.25 if she goes with coupon A.
We can see that coupon B gives the lower price because we have more in savings (since 18 is larger than 14.25).
If she goes with option A, then she spends 95-14.25 = 80.75 dollars. If she goes with option B, then she spends 95-18 = 77 dollars. Going with option B means she saves 80.75-77 = 3.75 dollars
Or you could note that 18-14.25 = 3.75 is another way to find out how much is saved when comparing the two coupons.

The profit from a business is described by the function P(x) = -x^2 + 10x - 4, where x is the number of items made, in thousands, and P(x) is the
profit in dollars. How many items will maximize the profit?
A 5,000
B. 10,000
C. 20,000
D. 50,000
Therefore, 5000 items can maximize the profit
The correct answer is an option (a)
What is Profit ?The money that you make when you sell something for more than it cost you.
For given example,
profit is described by the equation :
[tex]P (x) = -x^2 + 10x -4[/tex]
We need to maximize the profit P(x)
[tex]\Rightarrow \frac{d}{dx}P(x)=0\\\\\Rightarrow \frac{d}{dx}( -x^2 + 10x -4 ) =0\\\\\Rightarrow -2x+10=0\\\\\Rightarrow -2x=-10\\\\\Rightarrow x=5[/tex]
since , x is the number of items made in thousand
Therefore, 5000 items can maximize the profit
The correct answer is an option (a)

Lucy knows about 6 Web sites that sell a designer T-shirt she loves. The mean price of the T-shirt is $14 and the range of price is $7. What are possible prices for the T-shirt?
Answer:
D
Step-by-step explanation:
Given that :
Mean = 14
Range = 7
Evaluating the options given :
A. $14, $14, $14, $14, $7, $7
For option A :
Mean = (14 + 14 + 14 + 14 + 7 + 7) = 70 / 6 = 11.66 (incorrect)
B. $14, $14, $14, $14, $14, $21
Mean = (14 + 14 + 14 + 14 + 14 + 21) = 91 / 6 = 15.17 (Incorrect)
C. $13, $13, $13, $15, $15, $15
Range = 15 - 13 = 2 ( Incorrect)
D. $13, $12, $15, $15, $11, $18
Range = (18 - 11) = 7
Mean = (13+12+(15*2)+11+18) / 6 = 84/6 = 14
Option D is Correct
