Answer: X=1.5
Step-by-step explanation:
Solution
Perimeter= 2(l+w)
25= 2( 3x+4 +2x+1)
25= 2(3x+2x+4+1)
25= 2(5x+5)
25= 10x+10
Now subtract 10 on both sides..
25-10= 10x+10-10
15=10x
Now divide 10 on both sides to get x
15/10= 10x/10
1.5=X
Answer
The density of the gold is 772.8 kilograms\cubic meters
Answer:
x ≈ 26.4
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos47° = = = ( multiply both sides by x )
x × cos47° = 18 ( divide both sides by cos47° )
x = ≈ 26.4 ( to the nearest tenth )
If 50 students prefer vanilla ice cream then 259 students were surveyed.
Answer:
C, 0.28 x 63 = p
Step-by-step explanation:
Basically, C is getting 28% of 63.
This can be better shown in terms of 100. Let's say you want 28 percent of 100.
0.28 x 100 = 28
