Answer:
x=9
Step-by-step explanation:
2x+10=28
2x=18
x=9
Answer:
D for the first one A for the second
Using the formula for lines y=mx+b
To find out the gradient of the line, we do (y2-y1)/(x2-x1).
(3-6)/(-1-2)= -3/-3= 1 is the slope of the line
So far, y=(1)x+b
Now substitute one of your given coordinates into this equation:
6=2+b
b=4
Therefore, the equation of the line is y=x+4
97.336 is the answer i found it on a calculator, hope it helps :)
Answer: 1.33-inch wheels
Step-by-step explanation:
The scale factor is 1 : 12. (i.e 12 inches on the actual is represented by one unit on the scale model)
So, If the actual car has 16-inch wheels,
The size of the wheels on the scale model will be 16-inch / 12 = 1.33-inch
Thus, Thom's car will have 1.33-inch wheels
