Make me brainliest please
Answer:
Since we knew that the triangles are similar, we have:
19/38 = (x + 7)/(3x + 3)
=> 1/2 = (x + 7)/(3x + 3)
=> 3x + 3 = (x + 7) . 2
=> 3x + 3 = 2x + 14
=> 3x - 2x = 14 - 3
=> x = 11
This question is actually alot easier than it sounds.
Actual height = 412
Model height = 4
Seems easier?
Doesn't?
Divide
412/4 = 103 scale of model
*now i need those points*
Answer:
s = 32
Step-by-step explanation:
First distribute the -5:
-5s + 150 = -10
Add 10 to both sides
-5s = 160
Divide by -5 on both sides
s = 32
Answer:
Slope= 7/5
Step-by-step explanation:
The slope of a line is determined as a ratio of the change in y to the change in x.
Slope=Δy/Δx
Δy=y₂-y₁
Δx=x₂-x₁
Therefore we can use the the x and y coordinates from the points given, (-3,0) and (2,7) to calculate the slope.
m= (7-0)/(2-⁻3)
Slope= 7/5
When a negative number is subtracted from a number it the operation sign changes to addition.
