The answer is 4, 320, 000
explanation: the problem is asking what the population of city c is, and to do that you need to multiply city b times 2. therefore you do not need the population of city a, it is just there to confuse you
Answer:
9x + 1 = 7x + 13
<=> 2x = 12
<=> x = 6
with x = 6, UW = 7.6 + 13 = 55

Answer:
a = 0.
Step-by-step explanation:
2(a - 4) = 2a - 8 + 4a
2a - 8 = 2a - 8 + 4a
2a - 2a - 4a = -8 + 8
-4a = 0
a = 0.
Answer:length of the strip =3 1/3 meters
Step-by-step explanation:
Step 1
Given that
Area of the rectangular strip= 2/3 square meter
width = 1/5 meter
length = ?
W e know that the formulae for area of a rectangle = Length x width
using this equation, we will solve for length
Step 2
area of the rectangular strip= Length x width
Length = Area / Width
2/3 square meter / 1/5 meter
Length= 2/3 x 5/1 = 10/3= 3 1/3 meter
Answer:
y = -x + 2
Step-by-step explanation:
for this problem, you need the equation of a line.
the equation for a line -----> y = mx + b
- m = the slope (
) - b = the y-intercept of the line
1) b is always the easiest to find! it's always where y = 0. when you look on the graph, you will see that when y = 0, x = 2. that's the y-intercept!
y = mx + 2
2) let's find the slope now! rise is how much the line increases or decreases (up or down), run is how far across the line moves (left to right).
- this line <u>decreases </u> 2 spaces and is moving left 2 spaces
- 2/2 = 1
y = 1x + 2 or y = x +2
3) the final step is seeing if this line is negative or positive. the way you can tell is if it increasing or decreasing. this line is decreasing and you can tell because it starts high in the left corner, and falls in the bottom right.
y = -x + 2
