Answer:
yo
Step-by-step explanation:
we know that
Perimeter of a triangle is equal to
P=a+b+c
where
a,b and c are the length sides of the triangle
<u>Find the perimeter of the triangles</u>
<u>Triangle N 1</u>
P=(x-2)+(x)+(3x+1)-------> P=5x-1
<u>Triangle N 2</u>
P=(2x-5)+(x+4)+(6x-7)------> P=9x-8
equate the perimeters
5x-1=9x-8--------> 9x-5x=-1+8-------> 4x=7
x=7/4------> x=1.75
therefore
the answer is
x=1.75
A) (5s + 2 / 4) x (4) = Perimeter
B) ( s + 9) x (2) + ( 3s - 5 ) x (2) = Perimeter
C) 22 + 48 = 70
Multiply 80 by 5/8ths.
80*5/8=50
Answer:
A: Neither is a better deal, they cost the same person cubic foot
------
B: The large truck's volume is 2.3 times greater than the small truck's
C: At least: three vans, or two small trucks, or one large truck
Step-by-step explanation:
V=Lhw R=$/ft³
Vv=10.5(6)(6)
Vv=378 ft³
Rv=94.5/378
Rv= 25¢ per ft³
Vs=12(8)6.75
Vs=648 ft³
Rs=162/648
Rs=25¢ per ft³
------
Vl=20(8.75)8.5
Vl=1487.5 ft³
1487.5=648n
2.295=n
