What is y when x =17
Answer:
The answer is 30
Answer:
y = 30
Step-by-step explanation:
There are 2 ways to find the answer to this.
#1
The relationship between x and y is y = x+13.
x is 17 so 17+13 would equal y.
17+13 = 30
y = 30
#2
rule for y: y increases by 4
26+4 = ?
26+4 = 30
y = 30

Solve y = x + 6 for X.
x= y + 6
x= -y + 6
x = y - 6
x= -y - 6
Answer:
x=y-6
Step-by-step explanation:
First, flip the equation.
x+6=y
Finally, add -6 to both sides.
x+6+−6=y+−6
x=y−6

In a company, 65% of the workers are women. If 1820 people work for the company who are men, how many workers are there in all?
Answer:
women=x=65%
so men=100-65=35%=1820
let total workers be y
atq....y×35/100=1820=y=5200workers
6. Write an equation for a line that passes through (6, 12) and (10, 20).
Answer:
Step-by-step explanation:
Y = mx +b / Slope intercept form
mx - y = -b / Standard form
6m -2 = -b / Plug in ( 6,2)
-9m -10 = -b / Plug in ( -9, 10)
Solve the system of equation for m and b.
6m -2 = -9m -10 , then 15m = -8 m = -8/15
b = -6m +2 ,then b= -6 ( -8/ 15) +2 = 78/15
-8/15 X - y = - 78/15
8X +15y = 78 / Equation of in standard form
Note: This is a different methods of solving this problem. All methods find their roots coming from the basic premises.
Equation of a line in the slope intersect form is
Y = mx +b
To convert to standard form of ax + by =c
Simply move over the parameters
mx - y = -b where a = m , and c = -b
Then we feed coordinates of 2 points in there
make a 2 equation with 2 unknown( m,b) to
solve.
the length of the rectangle is 7 cm less than 4 times its width the area is 15 square cm
Answer:
I guess the answer is 4.4 cm or 22/5 cm
Step-by-step explanation:
AREA= 15cm^2
Let the Breadth be x
Length= 4x-7
Area = l×b
15 = 4x-7×x
15+7=4x+x
22=5x
22÷5=x
4.4=x
Therefore, Breadth= 4.4cm Length= 10.6cm

-8x is less than or equal to 32
What is the inequalities that are possible.
Answer:
We conclude that:
[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
The solution graph on the number line is also attached.
Step-by-step explanation:
Given the inequality
[tex]-8x\:\le 32[/tex]
Solving the inequality
[tex]-8x\:\le 32[/tex]
Multiply both sides by -1 (reverse the inequality)
[tex]\left(-8x\right)\left(-1\right)\ge \:32\left(-1\right)[/tex]
Simplify
[tex]8x\ge \:-32[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}\ge \frac{-32}{8}[/tex]
Simplify
[tex]x\ge \:-4[/tex]
Therefore, we conclude that:
[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
The solution graph on the number line is also attached.

A temperature probe registers a temperature
of -124° C. If the probe's temperature increases
by 8 °C per hour, after how many hours will it
be at a temperature of 4°C?
Answer:
16 hours
Step-by-step explanation:
Given
[tex]Initial = -124[/tex]
[tex]Rate = 8[/tex] per hour
Required
Determine the number of hours it gets to 4 degrees
Let the temperature at every hour, h be T.
So, we have:
[tex]T = Initial + Rate * h[/tex]
[tex]T = -124+ 8* h[/tex]
[tex]T = -124+ 8h[/tex]
To calculate the time it gets to 4 degrees. We first substitute 4 for T; then solve for h
[tex]4 = -124+ 8h[/tex]
Collect Like Terms
[tex]8h = 4 + 124[/tex]
[tex]8h = 128[/tex]
Solve for h
[tex]h = \frac{128}{8}[/tex]
[tex]h = 16[/tex]

Find the value of. X in the proportion 5/9=x/36
Answer:
x=20 hope this helps :)
The value of X is 20.
To find this answer, you must first find the least common denominator of both fractions. In this case, the LCD is 36.
Next, you multiply the left side by 4/4. The fraction 4/4 is simply found by dividing the right side denominator (36) by the left side denominator (9). 9 goes into 36 4 times.
5/9 * 4/4 = 20/36.
Thus meaning X = 20. I hope this helps!
Jamal has $15.00 to spend at the concession stand. He buys nachos for $7.50, and he wants to purchase some sour straws for $1.50 each. How many sour straws can Jamal purchase with the money that he has?(solve with inequality/solve for x)
Answer:
x = 5
$15.00 is the total amount of money Jamal has right? To find the remaining amount of money Jamal has subtract 15 - 7.5 (price of nachos) = 7.5 (remaining amount of money Jamal has.) Now for part 2, since the sour straws are $1.50 each you just have to multiply X to get close as close to the remaining amount of money as possible.
1.50× 5 (amount of sour straws) is equal to 7.50 (price of 5 sour straws).
To check your answer let's add the price of nachos (7.50) and 5 sour straws (7.50) which is 15.00 the total amount Jamal brought with him.

6. Two numbers are in the ratio of 2:3 If the bigger number is 6. what is the smallest one
_7. What number compared with 6 is the same as 36 compared to 6?
8. There are 24 red roses for every 6 roses. How many red roses are there if there
are 8 roses?
9.There are 7 children for every 2 adults in a plaza. How many adults are there,
if there are 21 children?
10.1f 12 pencils are bought for P60, how much will you pay for 25 pencils
Ratio of two numbers = 2:3
The larger number = 6
Let the smaller number be x.
Which means :
[tex] =\tt 2 : 3 \: = \: x : 6[/tex]
[tex] = \tt \frac{2}{3} = \frac{x}{6} [/tex]
[tex] =\tt 2 \times 6 = 3 \times x[/tex]
[tex] =\tt 12 = 3x[/tex]
[tex] =\tt x = \frac{12}{3} [/tex]
[tex]\hookrightarrow\color{plum}\tt \: x = 4[/tex]
▪︎Therefore, the smaller number = 4
○=> Solution (7) :36 compared to 6 = [tex] \tt \frac{36}{6} [/tex]
Let the number be x.
Which means :
[tex] = \tt \frac{36}{6} = \frac{x}{3} [/tex]
[tex] =\tt \frac{36 \div 2}{6 \div 2} = \frac{x}{3} [/tex]
[tex] =\tt \frac{36}{6} = \frac{18}{3} [/tex]
▪︎Therefore, the fractional number [tex] \tt \frac{18}{3} [/tex] is equal to [tex] \tt \frac{36}{6} [/tex].
○=> Solution (8) :Number of Rose's for 24 red Rose's = 6
This can be written in a ratio as 24:6
Number of roses = 8
Let the number of red roses for these roses be x.
Which means :
[tex] =\tt \frac{24}{6} = \frac{x}{8} [/tex]
[tex] =\tt 24 \times 8 = 6 \times x[/tex]
[tex] =\tt 192 = 6x[/tex]
[tex] =\tt x = \frac{192}{6} [/tex]
[tex]\hookrightarrow \color{plum}\tt x = 32[/tex]
▪︎Therefore, 32 red roses are there if there are 8 roses.
○=> Solution (9) :Number of children for 2 adults = 7
This can be written in a ratio as 7:2
Number of children in the plaza = 21
Let the number of adults be x.
Which means :
[tex] = \tt \frac{7}{2} = \frac{21}{x} [/tex]
[tex] =\tt7 \times x = 2 \times 21 [/tex]
[tex] =\tt 7x = 42[/tex]
[tex] =\tt x = \frac{42}{7} [/tex]
[tex] \hookrightarrow \color{plum}\tt \: x = 6[/tex]
▪︎Therefore, 6 adults were there in the plaza.
○=> Solution (10) :Cost of 12 pencils = P60
Cost of 1 pencil :
[tex] = \tt \frac{60}{12} [/tex]
[tex] =\tt P5[/tex]
Thus, the cost of one pencil = P5
Cost of 25 pencils :
= Cost of one pencil × 25
[tex] =\tt 5 \times 25[/tex]
[tex] \color{plum}=\tt \: P \: 125[/tex]
▪︎Therefore, the cost of 25 pencils = P125
A drama class has a total of 39 students. The number of males is 9 more than the number of females. How many males and how many females are in the class?
Answer:
Step-by-step explanation:M+F=39
M+F=39
F=M-9
Substitute
M + M - 9 = 39
2M = 48
M=48/2
M=24
24+F=39
F=39-24=15
F=15, M=24
Answer:
15 females
24 males
Step-by-step explanation:
Given;
39 students total
9 more male student than female
1. Set up an equation
Call the number of female student "x"
Since there are 9 more male students, the number of male students is (x + 9),
Assuming those are the only genders in the class, the equation formed is;
females + males = total
x + x + 9 = 39
2. Solve,
Simplify and inverse operations;
x + x + 9 = 39
2x + 9 = 39
2x = 30
x = 15
15 females
24 males
