xAnswer:
-10 -8 -6 -4
Step-by-step explanation:
The numbers are
first =x
second= x+2
third=x+4
4th= x+6
2(x + (x+4)) = 3(x+6)-20
4x+8 = 3x+18–20
4x-3x=18–20–8
x=-10
So the numbers are -10, -8, -6, -4
first 2nd 3rd 4th
Check:
2( -10-6) = 3(-4) -20
2(-16) = -12-20
-32 = -32
Answer:
10
Step-by-step explanation:
0.31 x 10 = 3.1
10z box = $5.90
1 oz = $5.90 ÷ 10 = $0.59
24 oz box = $6.48
1 oz = $6.48 ÷ 24 = $0.27
24 oz box is cheaper, it is a better buy
Answer:
Step-by-step explanation:
take 30 degree as reference angle
using cos rule
cos 30=adjacent/hypotenuse
/2=7/y(do cross multiplication)
14
=y
14
/=y
14=y
for x
using pythagorsa theorem
H^2=P^2+B^2
14^2=X^2+(7)^2
196=X^2+147
196-147=X^2
49=X^2
=X
7=X
