Answer:
X = -5
Step-by-step explanation:
3x-4=5x-10
Subtract 3x from both sides
-4=2x-10
Add 10 to both sides
6= 2x
X= 3
3 times 3-4
AB=5
Answer:
131.3 miles
Step-by-step explanation:
The two cars are moving from different directions. The total distance between the two cars = 118 miles + 256 miles = 374 miles.
Let us assume that the two cars meet at point O, let the distance between car c and O be d₁, the distance between car d and point O be d₂, hence:
d₁ + d₂ = 374 miles (1)
Let speed of car d be x mph, therefore speed of car c = 2x mph (twice of car d). If it take the cars t hours to meet at the same point, hence
For car c:
2x = d₁/t
t = d₁ / 2x
For car d;
x = d₂/t
t = d₂/ x
Since it takes both cars the same time to meet at the same point, therefore:
d₁/2x = d₂ / x
d₁ = 2d₂
d₁ - 2d₂ = 0 (2)
Solving equation 1 and 2 simultaneously gives d₁ = 249.3 miles, d₂ = 124.7 miles
Therefore the distance from point of meet to Boston = 249.3 - 118 = 131.3 miles
Answer:
15 girls, 35 boys
Step-by-step explanation:
Step 1:
3 : 7 Ratio
Step 2:
3x + 7x = 50 Substitute
Step 3:
10x = 50 Add
Step 4:
50 ÷ 10 Divide
Step 5:
x = 5
Answer:
15 girls, and 35 boys Multiply
Hope This Helps :)
The greatest common factor of 64 and 96 is... uhh... hmm... 32! Because 64/32 is 2, and 96/32=3. 2 and 3 have no factors in common, except 1.
The answer is 32(2+3).
This means 32*2 + 32*3
this is the same as 64+96
