Answer:The scale is 1:12, and the actual car has 16-in wheels.
Step-by-step explanation:
So the setup would be a proportion:
1 over 12=x over 16
Then cross-multiply
12x=16
Divide by 12
X=16/12
=4/3 or 1 and 1/3 in. wheels on the model car.
Answer:
15 cm
Step-by-step explanation:
area stands for amount of space in certain spot therefore the answer would be 15
BRAINLIST PLEASE!
The slope(m) is 2/3
Passes through (3,4)
Take a second point (x,y)
Slope(m) = Change in y-axis divide by change in x-axis
(y-4) ÷ (x-3) = 2/3
y - 4 = 2/3x - 2
y = 2/3x + 2
Answer:
Step-by-step explanation:
I assume you mean simple linear equations, maybe not factoring. Anyhow Ill do a few examples:
1. 2x + 5 = 19
2. 14 - 3x = 23
3. 50x / 5 = 150
1. 2x + 5 = 19
Subtract 5
2x = 14
Divide by 2
x = 7
2. 14 - 3x = 23
Subtract 14 to the other side because we have to isolate the term with x in it
-3x = 9
Divide by -3
x = -3
3. 50x / 5 = 150
Multiply by 5 to isolate the value with x
50x = 750
Divide by 50
x = 15
I dont know if this is what you are looking for but this is general idea of how to solve these types of questions. If you need factoring or help with quadratics then let me know!
Answer:
Zero's are X = 2 and X = -7
Step-by-step explanation:
you would set the factorized parts equal to zero, as in x - 2 = 0 and x + 7 = 0, then solve for x, and whatever you get is where y will be zero
