Answer:
x=4
Step-by-step explanation:
3×5=15 therefore, 7+2x=15
15-7=8
8÷2=4
Making x equal to 4
Answer:
x= -3
Step-by-step explanation:
Rewrite the equation 7+2x/3=5
Now subtract 7 from both sides to isolate x.
2x/3= -2
Now to isolate 2x, multiply each side by 3
2x=-6
x=-3
Check 7+2(-3)/3=5
7-6/3=5
7-2=5
So this is correct
A flower garden is circular. The diameter of the garden is 20 feet. Which is the closest to the total area of the garden?
Answer:
40
Step-by-step explanation:
The total area of the garden is 31.75 sq meters
The first step is to calculate the radius if the circle
The diameter of the garden is 20 feet
2π × radius= 20
2π × 3.14= 20
6.28π= 20
π= 20/6.28
π= 3.18
The area of the flower garden can be calculated as follows
= π × radius²
= 3.14 × 3.18²
= 3.14 × 10.1124
= 31.75 sq meters
Hence the total area of the garden is 31.75 sq meters

Step-by-step explanation:
Option A is correct, [tex]-6x^a^-^2+5x^b^-^2[/tex] is the right quotient of the expression [tex]\frac{ (36x^a - 30x^b) }{-6x^2}[/tex]
What is Division?A division is a process of splitting a specific amount into equal parts.
The given expression is[tex]\frac{ (36x^a - 30x^b) }{-6x^2}[/tex]
Thirty six times of x power a minus thirty times of x power b divided by minus six times of x square.
Factor 6 from the numerator.
Six times of six x to the power pf a minus five times of x power b divided by the minus six times of x square.
[tex]\frac{6(6x^a-5x^b)}{-6x^2}[/tex]
When we divide numerator and denominator by 6, 6 will be cancelled in numerator and denominator
[tex]-6x^a/x^2 + 5x^b/x^2[/tex]
When the denominator exponent is taken to numerator then it will be multiplied with negative sign.
[tex]-6x^a^-^2+5x^b^-^2[/tex]
Hence, Option A is correct, [tex]-6x^a^-^2+5x^b^-^2[/tex] is the right quotient of the expression [tex]\frac{ (36x^a - 30x^b) }{-6x^2}[/tex]

Answer:
-4
Step-by-step explanation:
In a linear equation, the terms "unit rate", "rate of change", "constant of proportionality", and "slope" all refer to the coefficient of x (the independent variable).
Here, the coefficient of x is -4.
The slope is -4.
_____
Additional comment
Strictly speaking the "constant of proportionality" only refers to the x-coefficient (k) when the equation is of the form ...
y = kx . . . . . with no added constant
"Slope", "unit rate", and so on, can also refer to the x-coefficient (m) when the equation has a non-zero y-intercept (b):
y = mx + b

Can someone help please
Answer:
14.5 units
Step-by-step explanation:
we need to find the length of the rectangle. To do that, we must find the hypotenuse of the right triangle below the rectangle.
Finding the hypotenuse of a right triangle uses the Pythagorean theorem, or a² + b² = c²
let a be 9 and b be 7.
9² + 7² = c²
81 + 49 = c²
130 = c²
√130 = c
c = approx. 11.4
Now, we know the length of the rectangle.
Once a rectangle is cut diagonally, it forms 2 equal right triangles. We will use the same process to find the hypotenuse of the second right triangle.
9² + 11.4² = c²
81 + 130 = c²
81 + 130 = approx. 211
c² = 211
√211 = c
c = approx. 14.5

Answer:
graph needs a solid dot at 13(c) ... at least 130 miles. ... at least 13 weeks.Step-by-step explanation:
The ≥ symbol means "greater than or equal to". In English, it is equivalent to "at least". On a graph, the boundary dot is drawn as solid to indicate the value represented by the dot is part of the solution.
The inequality is recognizable as the sum of miles added each week (6x) and the number of miles already completed (52). That is said to be greater than or equal to 130, so we presume the road crew's goal is "at least 130 miles."
The solution to the inequality is graphed as x ≥ 13, so we presume the time required to meet the goal will be "at least 13 weeks."
These statements match the 3rd choice.

What if the Ferris wheel below had equally spaced seats, such that the central angle were 20∘. If the radius of the Ferris wheel is 20 feet. How far is the space between the two adjacent seats?
Answer:
about 7 feet
Step-by-step explanation:
The formula to find am arc length of a circle is 2(r)π·Ф/360
Ф=data
r=radius
The word problem provides the radius and the data so just substitute the values to get your answer.
r=20
Ф=20
2(20)(20)π/360
800/360·π
Now, you'd get 2.2 repeated but you'd want to turn it into fraction form then multiply by π.
20/9·π=6.98
It is personally preferable if you round 6.98 to the nearest whole number which is about 7 feet. Hope this helps!
