Can some explain me how to find the answers

r = 2m + 3
r + m = 15
(b) The easiest way to solve this equation would be to use substitution. The first equation says that r is equal to "2m + 3", so we can plug 2m + 3 in for the r in the second equation, and then solve for m:
Now that we have m, we can plug it into one of the equations to find r:
So, the weight of Rajesh's package is 11 pounds, and the weight of Mohib's package is 4 pounds. This makes sense because both of these add up to 15 and Rajesh's package is three more than two times the weight of Mohib's package, as described in the question.
(c) Mohib's graph is the correct graph because it intersects at the correct point (4 on the Mohib axis and 11 on the Rajesh axis). The other graph shows the intersection of the two lines at the wrong point, giving the wrong weights of the two packages.

Simplify both sides of the equation
4(x-3) = 7x+24
4x-12 = 7x+24
Subtract 7x from both sides
4x-12-7x= 7x+24-7x
-3x-12= 24
Add 12 to both sides
-3x-12+12 = 24+12
-3x=36
Divide both sides by -3
-3x/-3= 36/-3
x = -12

Answer:
y = 4x + 7
Step-by-step explanation:
parallel = same slope
y = 4x + b
plug in (-4, -9)
-9 = 4(-4) + b
-9 = -16 + b
b = 7
y = 4x + 7
Answer:
7=4x+7
Step-by-step explanation:
To do this you would just plug in (-4,-9) into the equation y=mx+b so we would get -9=4(-4)+b when you simplify you will get -9=-16+b so we would add 16 to both sides and we would get 7=b so we would know that the y intercept is 7 and we know that if a line is parallel to another line is just has a different b so for our equation we would get 7=4x+7

The nearest a thousand the 7298 as the number is closer to 7000, so 7000 is the nearest a thousand.
What is a thousand?
A thousand is equal to 10 multiplied by 100. It is either 1,000 or 1000 in number. A phrase (such as a thousand, which has the same meaning as 1,000) or another number, such as two thousand (2,000), ten thousand (10,000), or nine hundred ninety-nine thousand, nearly usually comes before the word a thousand (999,000). The figure that is depicted by a one and six zeros
A thousand intervals in which the number 7298 is lying is 7000 - 8000
Here, the number is 298 away from the 7000 and 702 from the 8000, which means the number 7298 is closer to the 7000,
Thus, the nearest thousand is 7000.

Answer:
8, 36, 81, 11, 7, 1000
Step-by-step explanation:
A
Lets start with number one.
x^2 = 64.
That means that x times x equals 64.
To find x's value, simply find the square root of 64, which is 8.
So x = 8.
For the second one, the square root of x is 6.
That means that 6 x 6 = x
6 x 6 = 36.
So, x = 36.
B
For the third one, the square root of x is 9.
That means that 9 x 9 = x
9 x 9 = 81
So, x = 81.
For the fourth one, x^2 = 121
That means x times x = 121
To find x's value, simply find the square root of 121, which is 11
So, x = 11.
C
For the fifth one, x^3 = 343.
That means that x times x times x = 343
To find x's value, simply find the square root of 343, which is 7.
So, x = 7.
For the sixth and last one, the cube root of x is 10.
That means 10 x 10 x 10 = x.
10 x 10 x 10 = 1,000
So, x = 1,000
I hope this helps! :)
