first subtract 20 from both sides then you'll have
x/-3=10 then multiply both sides with -3
you should have x by itself and -30 on the other side
answer x=-30

Is 7 + square root of 5 equal to square root of 5 plus a number, what do you know about the number? Why?
The flag of a country contains an isosceles triangle. (Recall that an isosceles triangle contains two angles with the same measure.) If the measure of the third angle of the triangle is 15° more than the measure of either of the other two angles, find the measure of each angle of the triangle. (Recall that the sum of the measures of the angles of a triangle is 180°.)
Answer:
Angle total (180°) = 15° + other 2 angles
165° = other 2 angles
EACH of the other 2 angles = 165/2 = 82.5°

A jug holds 5 gallons of water. If a glass holds 4 ounces of water. How many glasses cam be drawn from the water jug?
Conversion Factors.
1 cup = 8 fluid ounces.
4 cups = 1 quart
4 quarts = 1 gallon
Solution
Use a method call unit fractions. It is simple to use. All you do is arrange the fraction so that 1 part of the unit fraction on the right cancels with 1 part of the fraction on its left. Then divide the numerator by the denominator when each has been multiplied. All this will become clearer if you follow the example below.
[tex]\text{5 gallons} * \dfrac{4 quarts}{1 gal}*\dfrac{4 cups}{1 quart}*\dfrac{8 oz}{1 cup}*\dfrac{1 glass}{4oz}[/tex]
numerator: 5 * 4 * 4 * 8 * 1 = 640
denominator: 1 * 1 * 1 * 1 * 4 = 4
Answer: numerator/ denominator = 640/4 = 160 glasses / 5 gallons.

How many cattle are there on the lazy circle double bar for square ranch
Answer:
There are 5000 cattle
Step-by-step explanation:
Based on your given information there should be 5000 cattleN=100×50
The simplified expression is 22m + 42, and the number of cattle on the Lazy Circle Double Bar for Square Ranch depends on the value of m that represents the relevant metric for cattle population.
To simplify the expression 7(2m + 6) + 8m, we first distribute the 7 across the terms inside the parentheses:
7(2m + 6) = 7 * 2m + 7 * 6 = 14m + 42
Then, we combine like terms by adding the 14m and 8m:
14m + 8m = 22m
Now, we substitute this result back into the original expression:
7(2m + 6) + 8m = 14m + 42 + 8m = 22m + 42
So, the simplified expression is 22m + 42.
To find the number of cattle on the Lazy Circle Double Bar for Square Ranch, we need to know the value of m, which represents the number of cattle per unit area or another relevant metric. Once we know the value of m, we can substitute it into the simplified expression 22m + 42 to find the total number of cattle.
For instance, if m = 100, then the expression becomes 22(100) + 42 = 2200 + 42 = 2242 cattle on the ranch.
In summary, the simplified expression is 22m + 42, and the number of cattle on the Lazy Circle Double Bar for Square Ranch depends on the value of m that represents the relevant metric for cattle population.
The question probable may be:
How many cattle are there on the lazy circle double bar for square ranch. Simplify expression below and find your answer in the corresponding answer column.

Write the equation of line in slope-intercept form.
Line parallel to y=3x−2 that passes through the point (5,8)
y=3x-7 that's the answer
The equation of a line that is parallel to y=3x−2 and passes through the point (5,8) is y = 3x - 7, since parallel lines share the same slope and the y-intercept was calculated using the given point.
Explanation:To write the equation of a line that is parallel to a given line and passing through a certain point, you need to know that parallel lines have the same slope. The line y=3x−2 has a slope of 3. So the line parallel to it will also have a slope of 3.
The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept. Since we already have the slope, we only need to find the y-intercept, b. We do this by plugging the given point coordinates (5, 8) into the equation and solving for b:
8 = 3*5 + b, which gives b = 8 - 15 = -7.
Therefore, the equation of the line parallel to y=3x−2 and passing through the point (5,8) is y = 3x - 7.

Solve the problem. The formula d = rt gives the distance traveled in time t at rate r. If a bicyclist rides for 2.3 hours and travels 41 miles, what was her average speed ?
Question options:
a: 38.7 miles per hour
b: 5.6 miles per hour
c: 17.83 miles per hour
d: 9.43 miles per hour
Answer:
17.83
Step-by-step explanation:
d = r*t
d = 41 miles
t = 2.3 hours
r = ??
d = rt Substitute
41 = r * 2.3 Divide by 2.3
41 / 2.3 = r Switch sides
r = 41/2.3

two numbers sum to 65 twice the first subtracted from the second is 5 find the numbers
a+b = 65
b - 2a = 5
Solve one variable in terms of another:
b = 5 + 2a
Substitute in this variable:
a + 5 + 2a = 65
3a = 70
a = 23.3
Use this to find the other variable:
23.3 + b = 65
b = 41.7
Check the answer:
23.3 + 41.7 = 65
65 = 65
ANSWERS:
a = 23.3

if the average (arithmetic mean) of 2,7, and x is 12, what is the value of x
x is equal to 27.
In order to find the value of x, you have to use the average formula and solve for the missing variable. The mean formula is all of the numbers added together divided by the number of inputs.
(inputs added)/(number of inputs) = Average
(2 + 7 + x)/3 = 12 ----> Multiply by 3
9 + x = 36 ----> Subtract 9
x = 27
To find the value of x when the average of 2, 7, and x is 12, you set up and solve the equation (2 + 7 + x) / 3 = 12. After simplifying, you will find that x equals 27.
Explanation:The question asks us to find the value of x when the average (arithmetic mean) of the numbers 2, 7, and x is 12. To find the value of x, we use the formula for the arithmetic mean, which for three numbers is (number1 + number2 + number3) / 3 = average. So, we set up the equation: (2 + 7 + x) / 3 = 12.
First, we multiply both sides of the equation by 3 to eliminate the fraction:
2 + 7 + x = 36. Next, we add the known values on the left side: 9 + x = 36. Finally, to find x, we subtract 9 from both sides of the equation: x = 36 - 9, which simplifies to x = 27. Therefore, the value of x is 27.

A.

B.
77 square inches
C.

D.

The area cannot be calculated without knowing the shape of the object these measurements belong to or how these measurements are arranged. Different shapes require different calculations for area.
Explanation:The question is asking for the area of an object given certain dimensions, but without knowing what type of object these measurements belong to or how these measurements are arranged, it's impossible to accurately calculate an area. Area calculation differs based on the shape of the object. For instance, the area of a square or rectangle is calculated by multiplying its length by its width, the area of a circle is calculated using pi times the radius squared, and the area of a triangle is calculated by multiplying the base by the height and then dividing by two. Each of these calculations uses different dimensions in different ways. We would need more information to solve this problem.

The area of the object will be 63 square inches. Then the correct option is C.
It addresses the various forms' sizes, shapes, regions, and densities in both two and three dimensions.
In the event that w = 7 inches, x = 6 inches, y = 8 inches, z = 5 inches, and u = 3 inches, v = 4 inches.
The figure displays all of the dimensions.
The combination of two rectangles and one triangle then makes up the geometry's area.
Area is equal to the sum of the areas of the three triangles, the rectangles 1 and 2.
Area = 5 x 8 + 4 x 5 + (1/2) x 3 x 2
Area is 40 + 20 + 3.
Area = 63 square inches
Then, choice C is the right one.

Given points (5,102) (4,74) and (-2,-10)
We frame 3 equations using the given points
[tex]y=ax^2+bx+c[/tex]
Plug in (5,102)
[tex]102=a(5)^2+b(5)+c[/tex]
102 = 25a +5b + c -------> first equation
Plug in (4,74)
[tex]74=a(4)^2+b(4)+c[/tex]
74 = 16a +4b + c----> second equation
Plug in (-2,-10)
[tex]-10=a(-2)^2+b(-2)+c[/tex]
-10 = 4a -2b + c -----> third equation
Now we use the three equation and solve for a,b,c
Use first and second equation and subtract it
102 = 25a +5b + c
-74 = -16a -4b - c
----------------------------------
28 = 9a + b --------------> fourth equation
Subtract third equation from first equation
102 = 25a +5b + c
10 = -4a +2b - c
----------------------------------
112 = 21a + 7b --------------> fifth equation
Use fourth and fifth equation
28 = 9a + b
112 = 21a + 7b
Multiply the fourth equation by -7
-196= -63a -7b
112 = 21a + 7b
-----------------------
-84 = -42a
Divide by -42 on both sides
a= 2
Plug in the value of a=2 in fourth equation
28 = 9a + b
28 = 9(2) + b
28 = 18 + b ( subtract 18 from both sides)
b = 10
Plug in the values in third equation and find out c
-10 = 4a -2b + c
-10= 4(2) -2(10)+c
-10 = -12 + c
c= 2
We got a=2, b=10 and c=2
So equation becomes [tex]y=2x^2+10x+2[/tex]
