Answer:
she increased her body guards by 20%
Step-by-step explanation:
15-12 = 3
3/15 = .2 or 20%
OR you can do it like...12/15 = .8
100%-80% = 20% more body guards.
hope that helps
Length of Xianren Bridge is 400 feet.
l represents the length of other natural arches.
Since, Xianren Bridge is the longest arch, we have,
l < 400
Let's graph this inequality.
Take the other natural arches along x-axis and the lengths along y-axis.
Clearly, the graph of l = 400 is a straight line parallel to x-axis.
So, l < 400 is the region below the line l = 400.
Answer:
x = -1 and y = -1
Step-by-step explanation:
Solve 3x+3y=−6;−x+y=0
Steps:
I will solve your system by substitution.
−x+y=0;3x+3y=−6
Step: Solve−x+y=0for y:
−x+y+x=0+x(Add x to both sides)
y=x
Step: Substitutexforyin3x+3y=−6:
3x+3y=−6
3x+3x=−6
6x=−6(Simplify both sides of the equation)
6x
6
=
−6
6
(Divide both sides by 6)
x=−1
Step: Substitute−1forxiny=x:
y=x
y=−1
Answer:
x=−1 and y=−1
Answer:
54 degrees
Step-by-step explanation:
Complementary angles add to 90 degrees
3:2
Multiply each by x
3x:2x
Add the angles together and set equal to 90
3x+2x = 90
Combine like terms
5x= 90
Divide each side by 5
5x/5 = 90/x
x =18
The angles are 3x = 3(18) =54
and 2x = 2(18) = 36
