Step-by-step explanation:
w(x)=5/6x-3;w(x)=-18
Answer:
x = -18
Step-by-step explanation:
Step 1: Define
w(x) = 5/6x - 3
w(x) = -18
Step 2: Substitute and Evaluate
-18 = 5/6x - 3
-15 = 5/6x
x = -18

What is the solution to this equation?
2x + 3 = x − 4
Answer:
x = −7
Step-by-step explanation:
2x + 3 = x − 4
Subtract 3 from both sides of the equation
2x = x −7
Subtract x from both sides of the equation
x = −7
Answer:
X=7
Step-by-step explanation:
Step 1
Having all the
x
terms on one side of =
Subtract
2 x
from both sides
2 x − 2 x + 3 = 3 x − 2 x − 4
0 + 3 = x − 4
Swap round
x − 4 = 3
Step 2
Have just
x
on the left of =
Add
4
to both sides
x − 4 + 4 = 3 + 4
x = 7

Answer:
5 cm/s
Step-by-step explanation:
The rate of change (ROC) is the speed at which the y variable (hieght) increases with the x variable (time). so ROC = 5.
the linear equation is y = mx + b, m is also the roc, b is the initial value, so,
if y = 60, x = 4 & b = 40, then making m the subject of equation will give the value of the ROC. i.e m = (y - b)/x = (60 - 40)/4.
The total weight of 15 boxes is 45 pounds. How much would 40 boxes weigh? *
Answer:
120 pounds
Step-by-step explanation:
15 boxes = 45 pounds
45/15= 3
1 box= 3 pounds
40 x 3 = 120
40 boxes would weigh 120 pounds
hope this helps :)
Answer: 120 lbs.
Explanation: One box weighs 3 pounds (divide 45 by 15). 3 times 40 equals 120. So the total weight is 120 pounds.

. If the difference between a number and its reciprocal is 24/5, find the number.
Answer:
The answer is 5/25 you just switch it
Answer:
number is 5
Step-by-step explanation:
The reciprocal of a number n is [tex]\frac{1}{n}[/tex] , thus
n - [tex]\frac{1}{n}[/tex] = [tex]\frac{24}{5}[/tex]
Multiply through by 5n to clear the fractions
5n² - 5 = 24n ( subtract 24n from both sides )
5n² - 24n - 5 = 0 ← in standard form
(n - 5)(5n + 1) = 0 ← in factored form
Equate each factor to zero and solve for n
n - 5 = 0 ⇒ n = 5
5n + 1 = 0 ⇒ 5n = - 1 ⇒ n = - [tex]\frac{1}{5}[/tex]
However, n > 1 , thus n = 5
That is the number is 5

Answer:
The mean age of the frequency distribution for the ages of the residents of a town is 43 years.
Step-by-step explanation:
We are given with the following frequency distribution below;
Age Frequency (f) X
0 - 9 30 4.5 135
10 - 19 32 14.5 464
20 - 29 12 24.5 294
30 - 39 20 34.5 690
40 - 49 25 44.5 1112.5
50 - 59 53 54.5 2888.5
60 - 69 49 64.5 3160.5
70 - 79 13 74.5 968.5
80 - 89 8 84.5 676
Total 242 10389
Now, the mean of the frequency distribution is given by the following formula;
Mean =
= = 42.9 ≈ 43 approx.
Hence, the mean age of the frequency distribution for the ages of the residents of a town is 43 years

How many solutions to y=2x-3 y=-x+3
Answer:
One solution, as there is only one intersection between these two lines.
x = 2, and y = 1 (point of interesection (2, 1) )
y = 2x-3
y = -x + 3
first step is to substitute the y of one equation into the other and solve for x.
- x + 3 = 2x - 3
___________
+x. +x
_____________
3 = 3x-3
_____________
+3 +3
____________
6 = 3x
_____________
÷3 ÷3
_______________
2 = x
______________
x = 2
_______________
We can verify this value is true by substituting it back into the equations and as a result also solving for the working y value.
x = 2 -> y = 2(x) - 3
2(2) - 3 = 4 - 3 = 1
y = 1
____________
x = 2 -> y = -(x) + 3
-(2) + 3 = -2 + 3 = 1
y = 1

plz mark brainliest
The midpoint of the points R(-3,3) and S(1,6) is (-1,4.5).
What is a midpoint?A location that is halfway between two other points is considered to be a line segment's midway. The distance between the midway and each endpoint is the same.
The midpoint is calculated by using the formula:- ( x₁ + x₂ ) / 2 , ( y₁ + y₂ ) / 2.
Given points are R(-3,3) and S(1,6). The midpoint of the given points are calculated as below:-
M = (-3+1 ) / 2 , ( 3 + 9 ) / 2
M = ( -1,4.5)
Therefore, the midpoint of the points R(-3,3) and S(1,6) is (-1,4.5).
