Answer:
Step-by-step explanation:
Let 'x' be the original price.
x + 39% of x = 197.38
x + 0.39 x = 197.38
1.39x = 197.38
x = 197.38/ 1.39
x = 142
Answer:
55
Step-by-step explanation:
Since this is an isosceles triangle, the angles at the bases of the identical legs must be equal
<A = <C
3x+40 =x+50
Subtract x from each side
3x-x+40 = x+50-x
2x +40 = 50
Subtract 40 from each side
2x+40-40=50-40
2x = 10
Divide each side by 2
2x/2=10/2
x = 5
We want to find <A
3x+40
3(5)+40
15+40

Answer:
25min
Step-by-step explanation:
40 is the unit rate so 40 words per minute so it's 25 because 1000÷(40)*
(the unit rate)*. Sorry if I'm worng.
Answer:
1 m³
Step-by-step explanation:
first find volume of smaller cubes
V = lwh
S = 1/3*1/3*1/3
S = 1/27
find volume of large cube. there are 27 smaller cubes.
V = 27S
V = 27(1/27)
V = 1
S: volume of small cube
V: volume of large cube
