Answer:
xz=cb = 45/60 = .75
zy=ab = 30/40 = .75
xy=ac = 37.5/50 = .75
Step-by-step explanation:
all lines when put into ratio format show .75 scale factor big to little triangle side lengths.
Answer:
2√3
Step-by-step explanation:
Multiply these binomials in the usual way:
(1 +√3)(3 -√3) = 1(3 -√3) +√3(3 -√3)
= 3 -√3 +3√3 -3 = (3 -3) +√3(-1 +3)
= 2√3
You want to get 6 to equal the total (48) 48/6=8
So 5×8=40
And 6×8=48
So of the 48 tools he sold 40 of them were hammers
Answer:
There is another method for solving systems of equations: the addition/subtraction method. ... Multiply one or both equations by an integer so that one term has equal and opposite coefficients in the two equations. Add the equations to produce a single equation with one variable. Solve for the variable.
Answer:
7
Step-by-step explanation:
Note the relation between x and y
The values of y are 2 less than the corresponding values of x, that is
x = - 3 → y = - 3 - 2 = - 5
x = 0 → y = 0 - 2 = - 2
x = 1 → y = 1 - 2 = - 1
x = 5 → y = 5 - 2 = 3
Thus
x = 9 → y = 9 - 2 = 7 ← missing value
