A. 2x6x8=96 units^3
B. 1x7x4=28 units^3
C. 2x3x5= 30 units^3
D. 4x4x2= 32 units^3
E. 5x4x3= 60 units^3
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
10x + 2 = 7
10x = 7 - 2
10x = 5
x = 5/10 reduces to 1/2
2x = 2(1/2) = 1 <==
Answer:
x = 14
AB = 37
BC = 36
AC = 28
PQ = 28
QR = 28
PR = 45
Step-by-step explanation:
we can add together the sides of ΔABC and set it equal to the sum of the sides of ΔPQR
2x+9 + 2x+8 + 2x = 2x + 2x + 3x+3
combine 'like terms':
6x + 17 = 7x + 3
subtract 6x from each side to get:
17 = x + 3
subtract 3 from each side to get:
14 = x
CHECK:
Does 6(14) + 17 equal 7(14) + 3?
84+17 = 98+3
101 = 101 checks out correctly
The third equation is the correct one. After 100 years, about 115 grams will remain.
