-4x/5 < 20
(Show your work)
Answer:
x > -25
Step-by-step explanation:
Write it out: [tex]-\frac{4x}{5} < 20[/tex] Multiply each side by 5 to cancel out the 5 under -4x. It should now look like this: -4x < 100Divide each side by -4 to cancel out the -4 next to x. It should now look like this: x > -25I hope this helps!

150+25x=55x what is the answer?
Answer:
x = 5
Step-by-step explanation:
150+25x= 55x
-25x -25x
150= 30x
150/30 = 30x/30
x = 5
Hope this helps!
Answer: x =5
Steps: 150 + 25x = 55x
Subtract 150 from both sides: 150 + 25x - 150 = 55x - 150
Simplify: 25x = 55x - 150
Subtract 55x from both sides: 25x - 55x = 55x - 150 - 55x
Simplify: -30x = -150
Divide both sides by -30: -30x ÷ -30 = -150 ÷ -30
Simplify: x = 5

Solve each equation.
7(1 +4n) - 5=-38 + 8n
Answer:
B) n=-2
Step-by-step explanation:
First, distribute.
7(1+4n)-5=-38+8n
7+28n-5=-38+8n
Combine like terms.
2+28n=-38+8n
To make solving the equation easier, subtract 8n first, so there isn't a negative variable.
2+28n=-38+8n
-8n -8n
2+20n=-38
Subtract 2 on both sides.
2+20n=-38
-2 -2
20n=-40
Divide by 20 on both sides.
20n=-40
/20 /20
n=-2
Hope this helps!! Have a wonderful day :3

What is the equation of this line?
y= 2x - 3
y= 3x - 2
y= 1/3x - 2
y= 1/2x - 3
Answer:
y= 3x - 2
Step-by-step explanation:
The line passes through (0, -2). '-2' is the y-intercept.
The line passes through the points (2,4) and (1,1).
[tex]m=\frac{rise}{run}=\frac{1-4}{1-2}=\frac{-3}{-1}=3[/tex]
The equation should be y= 3x - 2.
Hope this helps.
A dancer took forward and backward steps of equal length during a dance. After taking 16 steps total, she was back at her starting position. How many steps did the dancer take in the forward and backward directions?
8 steps
this is because when she moves front, she takes 1 step back, so 16/2=8

How do I find x and what’s the relation ?
Answer:
X=17
Step-by-step explanation:
Im sorry if this sounds a bit confusing. Im better at doing the math then explaining it. All the angles in that are 90-degree angles and because of that, you can assume that the angle that you trying to find is also 90 degrees. So to find that equation you can do this.
4x+22=90 -22 from both sides.
-22=-22
you are left with
4x=68 then divide 4 from both sides.
/4=/4
you then get x=17 which is your answer.
Check your answer by plugging 17 into x.
4*17+22=90
The answer is 90 so you are correct.
What is the solution to the equation –5w + 3 = 4w – 6?
Answer:
-2=2
Step-by-step explanation:
Answer:
w = 3
Step-by-step explanation:
-5w + 3 = 4w - 6
were going to get the variable and the numbers on different sides
-5w + 3 - 3 = -5w
4w - 6 - 4w = -6
-5w + 4w = -1w or -w
-6 + 3 = -3
-w = -3
and since there're both negatives you can just take that away and you get
w = 3

find m
we learned this last week and I forgot, please help!
Answer:
x=8
Step-by-step explanation:
I think you mean find x, not m.
since angle DEG and angle GEF are a linear pair, they equal 180º.
18x-9 + 4x+13 = 180
22x + 4 = 180
subtract 4 from each side
22x = 176
divide each side by 22
x=8

1/3 (12f-3)=4f-1
Answer:
4F-1
Theres infinite amount of solutions
Step-by-step explanation:
12f/3=4f
-3/3=-1
4f-1=4f-1
Answer:
f = 0
No solutionStep-by-step explanation:
[tex] \frac{1}{3} (12f - 3) = 4f - 1[/tex]
Use ⅓ to open the bracket
[tex] \frac{1}{3} \times \: 12f = 4f \\ \frac{1}{3} \times 3= 1[/tex]
[tex]4f - 1= 4f - 1[/tex]
Collect like terms
[tex]4f - 4f = - 1+1 \\ - 1f = 0 \\ \\ f = 0[/tex]
Which linear inequality is represented by the graph?
Is this right?
Answer:
y ≤ [tex]\frac{1}{2} x + 2[/tex]
Step-by-step explanation:
≤ because the area below the line is shaded.

Do rozwiązania są następujące zadania tekstowe:
Luca ma kilka 10-centówek oraz kilka 5-centówek. Razem ma 40 monet, o wartości
3.15 Euro. Ile monet każdego rodzaju ma Luca?
d = liczba monet 10-centowych
p = liczba monet 5-centowych
Razem, Luca ma 40 monet:
d + p = 40
Jedna 10-centowa moneta ma wartość 10 centów, i jedna 5-centowa ma wartość 5 centów, więc
10d + 5p = 315
bo 3,15 euro = 315 centów.
Znajdź d i p :
(10d + 5p) - 5(d + p) = 315 - 5•40
5d = 115
d = 23
d + p = 40
23 + p = 40
p = 17

what is the approximate value of x?
Answer: 17 would be the approximate value of x.
Step-by-step explanation: 4 is the √16, so the value plotted on the number line, 4.1 represents the square root of a slightly larger number than 16.
In 1968 it cost $54 000 for a 30-second commercial during the super bowl. In 1973, the cost for a 30-second commercial was $88,000. What is the percent increase, rounded to the nearest whole number, in the cost for a 30-second commercial from 1968 to 1973?
Answer:
63 %
Step-by-step explanation:
Percentage change in value value for any number is given by
percentage change = (new value - old value) /old value * 100
we can also write it as
percentage change = (change in value ) /old value * 100
________________________________________
cost of commercial in 1968 = $54000
cost of commercial in 1973 = $88000
change in cost of commercial = cost of commercial in 1973 - cost of commercial in 1973 = $(88000-54000) = $34000
thus,
percentage change in cost of commercial
= change in cost of commercial/cost of commercial in 1968 * 100
= 34000/54000*100 = 62.96 %
Thus, percentage change in cost of commercial is 62.96 %
we have to round it to nearest whole number
rounded value of 62.96 is 63
in that case
percentage change in cost of commercial is 63 %
X2+ 5x -24=(x – 3) (x + m)
Answer:
m = 8
Step-by-step explanation:
put -24 into the equation so : [tex]x^{2} +5x -24[/tex] find two numbers that : times to make -24, and add to make 5those two numbers are 8 and -3 (since 8-3=5 and 8*-3=-24)put those into double brackets: (x-3)(x+8)(x-3)(x+8) = (x-3)(x+m)+8 goes into where m ism = 8FInd the GCF of the numbers using prime factorizations.
24,90
52,68
32,56,96
Also find the GCF of 28,48, 64
Answer:
GCF(330, 75, 450, 225) = 15
Steps:
Prime factorization of the numbers:
330 = 2 × 3 × 5 × 11
75 = 3 × 5 × 5
450 = 2 × 3 × 3 × 5 × 5
225 = 3 × 3 × 5 × 5
GCF(330, 75, 450, 225)
= 3 × 5
= 15
