Answer:
Ratio = 5/12
Jack had = $972
Step-by-step explanation:
<u>Given:</u>
- Total money $1377
- Amy had = x
- Jack had = y
- Amy spent = 0.8x
- Jack spent = 1/3y
<h3>Part A</h3>
<u>Since they spent same amount of money:</u>
- 0.8x = 1/3y
- 8/10x=1/3y
- x/y = 10*1/8*3 = 5/12
The ratio was 5/12
<h3>Part B</h3>
<u>Sum of money:</u>
<u>As per ratio, x = 5/12y, substituting x in above equation:</u>
- 5/12y + y = 1377
- 17/12y = 1377
- y = 1377*12/17
- y = 972
Jack had $972

Answer
42
Step-by-step explanation:
The area of a triangle is "triangle = BxH" Which in your case is 6x7
X is mick's age
twice: 2x
5 more than twice: 5 + 2x
So Tom's age= 5 + 2x
Get rid of brackets:
21x +6 +8x
Put 6 to the other side:
21x +8x = -6
27x = -6
Divide both sides by 27
X= -0.22
