Answer:
add 3.8 to both sides
Step-by-step explanation:
you always want the variable to be on one side so you must add 3.8 first

how many natural numbers from 78 to 234
Answer:
158 natural numbers
158 natural numbers from 78 to 234, and 699 whole numbers from 24 to 721. Step-by-step explanation: Natural numbers are positive integers (whole numbers), so all numbers from the range of 78 to 234 would be included, including 78 and 234 itself.
Hope this helps, have a wonderful day/night, stay safe, happy holidays, and merry christmas!
Step-by-step explanation:
Natural numbers are positive integers (whole numbers), so all numbers from the range of 78 to 234 would be included, including 78 and 234 itself. That is 158 natural numbers. Whole numbers are numbers without a fraction or decimal, they are integers. So all numbers from 24 to 721 would be included, as well as 24 and 721 itself. That is 699 whole numbers from 24 to 721. Hope this helps.
Factorise this expression as fully as possible
2xy2 + 8y
The factorization of the expression 2xy² + 8y will be 2y(xy + 4 ).
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is 2xy² + 8y. The factorized form of the expression is solved as below,
E = 2xy² + 8y
E = 2y ( xy + 4 )
Hence, the expression will be 2y( xy + 4 ).

y=2x-1 is the point with coordinates (5,11) on the line y=ex-1? true or false
Answer:
False
Step-by-step explanation:
Here, we want to check if the point given is on the line
To get this, we simply proceed to substitute the point given into the equation
Thus, we have;
11 = 2(5) - 1
11 = 10-1
11 is not equal to 9
Since these are not equal, then the point is not on the line

80% of the houses on main street where decorated for Christmas if there were 36 decorated houses how many houses on main street were not decorated for Christmas?
Answer:
9 houses were not decorated for christmas
Step-by-step explanation:
If 80% were decorated, then 20% were not decorated
80 to 20 is a ratio of 4 : 1
So the number of decorated houses is 4 times the number of undecorated houses
The number of undecorated houses will be
36/4 = 9

9514 1404 393
Answer:
-8 < r ≤ 3
Step-by-step explanation:
Divide by the coefficient of r. It is negative, so the comparisons will be reversed.
24/-3 < r ≤ -9/-3
-8 < r ≤ 3
The < has no "or equal to" as a part of it, so the number -8 is not in the solution set. There will be an open circle on the graph at that point.
The ≤ includes the "or equal to" case, so the number 3 is in the solution set. There will be a solid dot on the graph at that point.
The line is shaded between the two dots, because values in between -8 and 3 are part of the solution set.

9514 1404 393
Answer:
A) the elements in the domain of f(x) for which g(f(x)) is defined
Step-by-step explanation:
(g circle f)(x) means g(f(x)). In order for a value (x) to be in the domain of this function, f(x) must be defined. That is, x must be in the domain of f(x). In addition, g(f(x)) must be defined.

In ΔQRS, q = 91 inches, r = 67 inches and ∠S=109°. Find the length of s, to the nearest inch.
Answer:
The length of s is 129 inches to the nearest inch.
Step-by-step explanation:
In ΔQRS
∵ q is the side that opposite of ∠Q
∵ r is the side that opposite of ∠R
∵ s is the side that opposite of ∠S
∵ q = 91 inches, r = 67 inches, m∠S = 109°
→ To find side s we will use the cosine rule
∵ s² = q² + r² - 2(q)(r)cos∠S
∴ s² = (91)² + (67)² - 2(91)(67)cos(109°)
∴ s² = 16739.97808
→ Take square root for both sides
∴ s = 129.3830672
→ Round it to the nearest inch (whole number)
∴ s = 129 inches
∴ The length of s is 129 inches to the nearest inch.

Find the measure of the indicated angle that makes lines u and v parallel. Name the converse.
Answer:
59°
Step-by-step explanation:
Both the ? and 121° angles make up to 180° since the lines are (assumed) parallel.
So,
? + 121 = 180
? = 180 - 121
? = 59°
1) x + 4y = 20

2x - 2y + 3z = -6
answer:
x= 124/27
y= 104/27
z= -26/27
Step-by-step explanation:
To solve the system, rewrite it as two systems each consisting of two
[tex]\left \{ {{x+4y=20} \atop {x+5y+4z=20}} \right.[/tex]
[tex]\left \{ {{x+5y+4z=20} \atop {2x-2y+3z=-6}} \right.[/tex]
solve the system
-y-4z=0
7y+z=26
y= 104/27
z= -26/27
substitute the given value of y into the equation x+4y=20
x+4*104/27=20
x= 124/27
Answer:
the correct answer to this equation is: 124/27

Find the slope using the slope formula:
m = (y2 - y1) / (x2 - x1)
Plug in the points (-2, 8) and (0, 6) to solve:
m = (6 - 8) / (0 - (-2))
m = -2 / 2
m = -1
The y-intercept of the function is the y-value when x = 0.
According to the table, at x = 0, y = 6. Therefore, the y-intercept is (0, 6).
