Answer:
140 people
Step-by-step explanation:
We can make two ratios...
7:10
x:200
We can since 10*20 = 200, we can multiply 7 by 20 to get x.
x=7*20=140
140 people are expected to be able to curl their tongue
Answer:
Number of years between 1950 and 2100 =

150 = 50 + 50 + 50 years.

So, total population in 2100 is 375,000,000.
Answer:
y = -2x+2
Writing the slope was the more difficult part. Writing the y-intercept was the easiest because I had to select to points on the line and solve to get the slope. The y-intercept was already explicitly shown on the line.
Step-by-step explanation:
y = mx+b
y = -2x + 2
Answer:
Option 1
Step-by-step explanation:
The equations in the options are in the slope-intercept form (y= mx +c, where m is the slope and c is the y-intercept).
In the graph, the line cuts through the y-axis at y= -2. Thus, c= -2 and the 2nd option can be eliminated.
The slope can be found using the formula below.

Let's choose 2 points on the line: (0, -2) and (-2, 4)
Slope



= -3
The equation of the line is thus y= -3x -2.

Answer:
n = 4
Step-by-step explanation:
you have to do the opposite of whatever the equation is to cancel it out from one side
-6n + 22 = -4n + 14
8 = 2n
8 ÷ 2 = 4
n = 4
