Answer:
Step-by-step explanation:
pythagoras theorem
a^2+b^2=c^2
12^2+x^2=13^2
144+x^2=169
x^2=169-144
x=
x=5
Answer:
1153.5 miles (first answer choice)
Step-by-step explanation:
'1000 miles east' is the change in x ('the run'), and '575 miles south' is the change in x (the 'rise'). Since these two vectors form a right angle, we can immediately apply the Pythagorean Theorem without worrying about signs:
d = √(1000² + 575²) = 1153.5 miles (first answer choice)
C. 35 because if it is 35 roses, it will have to be 7 tulips. Divide 35 by 7 and get 5, and divide 7 and 7 to get 1.
X+(x+10)=104
2x=94
x=47
x+10=57
Your answers are 47 and 57. Hope this helps!

According to the statement of the question, we can assemble the following system of equation
X = 7 + 3Y i
X + Y = 75 ii
So, multiplying ii by -1 and adding with i
X = 7 + 3Y
- X - Y = - 75
- Y = 7 + 3Y - 75
4Y = 68
Y = 17
for X we will use ii:
X + Y = 75
X + 17 = 75
X = 58
The smaller number is: 17
