Answer:
y= -3.6
Step-by-step explanation:
-9.5(1.4)-2.5y=-4.3
-13.3-2.5y=-4.3
-9=2.5y
y=-3.6

10.) x+25=30
x=5
11.) 60=3x-12
72=3x
x=72/3
x=24
12.) <1+<2=90
<1+17=90
<1=90-17
m <1=73 degrees
13.) m <3+m <4=180
46+m <4=180
180-46=m<4
134=m<4
Answer:
Let x be the number of 3- point questions and y be the number of 5-points questions.
Step-by-step explanation:
Answer:
Step-by-step explanation:
AREA FORMULA: LENGTH * WIDTH
L*W=30
L=W+4 thus
(W+4)W=30
W^2+4W=30
W^2+4W-30=0
USING THE QUADRATIC EQUATION WE GET
X=(-B+-SQRT[B^2-4QC])/2A
X=(-4+-SQRT16-4*1*-30])/2*1
X=(-4+-SQRT16+120])/2
X=(-4+-SQRT136)/2
X=(-4+-11.66)/2
X=(-4+11.66)/2
X=7.66/2
X=3.83M IS THE WIDTH.
THUS THE LENGTH IS
L*3.83=30
L=30/3.83
L=7.83M IS THE LENGTH
