Answer:
d=12
Step-by-step explanation:
7d-28=56
Add 28 to both sides
7d=84
Divide both sides by 7
d=12
Cha Cha Real Smooth indeed! :3
Answer:
d=12
Step-by-step explanation:
first step is to add 28 to both sides and get 7d=84
then divide 84 by 7
d=12

Which is a reasonable first step that can be used to solve the equation 2(x + 6) = 3(x - 4) + 5?
Combine like terms, 3 and 5, on the right side of the equation.
Distribute 2 to x on the left side of the equation and 3 to x on the right of the equation.
Distribute 2 to (x + 6) and 3 to (X - 4)
Apply the subtraction property of equality to move the 6 from the left side of the equation to the right side.
Answer:
Distribute 2 to (x+6) and 3 to (x-4)
Step-by-step explanation:
The first thing you need to do when solving an equation with parenthesis is to always simplify the expression first before solving. This makes it easier to solve the equation.

The length of an arc of a circle is 9.42cm. If the diameter of the circle is 10cm, find the angle subtended by the arc at the center of the circle. (Take π = 3.142)
SHOW ALL WORKING.
Answer:
1.89 radians or 108 degrees.
Step-by-step explanation:
Circumference of the circle = 10 * 3.142
= 31.42.
So 31.42 is equivalent to 2 pi radians, so:
Angle subtended at the center
= (9.42 / 31.42) * 2 pi
= (9.42 / 31.42) * 2 * 3.142
= 1.89 radians or 108 degrees..
Please help me with those questions please please help

When graphing an equation in slope-intercept form, what is the first step.
Answer:
Typically the answer is Graph the y intercept because when you do slope intercept you cant always start with the origin unless you don't have a b to base it off of.

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term. 89, 178, 267, 356, ...
Answer:
a(n)=89n
Step-by-step explanation:
Given the sequence 89, 178, 267, 356, ...
First Term, a(1)=89
178-89=267-178=89
This is an arithmetic difference with:
Common difference, d=89
The position of any term, n in an arithmetic sequence is derived using the formula:
a(n)=a(1)+(n-1)d
Substituting a(1)=89 and d=89
a(n)=89+89(n-1)
a(n)=89+89n-89
a(n)=89n
The expression that describes the sequence above is: a(n)=89n where n is the position of a term in the sequence.

The population of the United States, u, is about one hundred thousand less than the population of India, i. Write and equation that represents the two populations.
Answer: u = i- 100,000
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given:
Population of the United States = u
Population of India = i
Since the population of the United States, u, is about one hundred thousand less than the population of India, i, we have to subtract 100,000 (one hundred thousand) to the population of India (i). That expression must be equal to the population of United States (u).
Mathematically speaking:
u = i- 100,000

On Rectangle QRST below, if Q is located at -6,-1 and S is located at 1, 5, find RT
Answer:
[tex]|RT|=\sqrt{85}$ units[/tex]
Step-by-step explanation:
On Rectangle QRST
QS is congruent to RT since they are opposite side of a rectangle.
If Q is located at (-6,-1) and S is located at (1, 5), we simply find the length of QS using the distance formula.
For points [tex](x_1,y_1)$ and (x_2,y_2)[/tex] on the coordinate axis,
Distance[tex]=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
In this case,[tex](x_1,y_1)=(-6,-1)$ and (x_2,y_2)=(1, 5)[/tex]
[tex]|QS|=\sqrt{(1-(-6))^2+(5-(-1))^2}\\=\sqrt{(1+6)^2+(5+1)^2}\\=\sqrt{(7)^2+(6)^2}\\|QS|=\sqrt{85}$ units[/tex]
Since
[tex]|QS| \cong |RT|\\ |RT|=\sqrt{85}$ units[/tex]
A circle has a radius of square root 131 units and is centered at (0,-4.3).
Whats the equation of this circle?
Answer:
x^2 + (y + 4.3)^2 = 131
Step-by-step explanation:
The basic equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2. Here the center is (0, -4.3) and the radius is √131. Substituting as indicated, we get:
(x - 0)^2 + (y + 4.3)^2 = 131, or
x^2 + (y + 4.3)^2 = 131
David's car used 8 gallons of gasoline to travel 340 miles. After a mechanic worked on the car, it used 7 gallons of gasoline to travel 350 miles.

A man came to the King and asked, "King, let me pick an apple from your garden." The King agreed to the request so the man went to the garden and saw that it was fenced off with three fences and that there was a gate in each fence. A guard stood next to each gate. "The King has allowed me to pick an apple from the garden," said the man to the first guard. "Go ahead," answered the guard, "but when you exit give me half of all the apples that you have, plus one more." The other two guards each said the same thing to the man. How many apples should the man pick in order to have one apple left for himself after he gives each of the guards all the apples they demanded?
Answer:
The Man must pic 22 Apples.
