Terms are the numbers and variables that are usually separated by an addition sign or a subtraction sign. In the expression 2x, 3y, 5z, and 4 are all terms.
Variables are the letters that come after a number. They represent the unknown number in the equation. The x, y, and z in the expression are the variables.
Coefficients are the numbers in front of the variables. For example, 2, 3, 5, and 4 are the coefficients.
The constants are the "signs" in between the terms. These include the addition sign and the subtraction sign.
Answer:
y=4/3x+4
Step-by-step explanation:
y-y1=m(x-x1)
y-(-8)=4/3(x-(-9))
y+8=4/3(x+9)
y=4/3x+36/3-8
y=4/3x+12-8
y=4/3x+4
How much is in one pack? then add one pack + pack and then divide it by 3
Answer:
see below
Step-by-step explanation:
a. -11r ≥ 220
Divide both sides by -11 to isolate r.
r ≥ -20
b.
-8 ≤ -7 + (x/10)
Add 7 to both sides.
-1 ≤ x/10
Multiply both sides by 10 to cancel out the denominator of x.
-10 ≤ x
c. -1 - 6(5q - 2) ≥ -139
Distribute the -6 across the parentheses.
-1 - 30q + 12 ≥ -139
Combine like terms on the left side.
-30q + 11 ≥ -139
Subtract 11 from both sides.
-30q ≥ -150
Divide both sides by -30 to isolate q.
q ≥ 5

Answer:
Percent = 9.6%
Step-by-step explanation:
Given the following data;
Number of suburbs = 170
Total number of suburbs = 1780
To find the percentage;
Percent = 170/1780 * 100
Percent = 17000/1780
Percent = 9.55 ≈ 9.6%
Therefore, 170 suburbs is 9.6 percent of 1780.
