Answer:
97, 485, 197
Step-by-step explanation:
<u>Given</u>:
- First number = a
- Second number = b
- Third number = c
<u>Then we have:</u>
- b = 5a
- c = 100+a
- a + b + c = 779
<u>Substituting b and c in the third equation:</u>
- a + 5a + 100+a = 779
- 100 + 7a = 779
- 7a = 779- 100
- 7a=679
- a= 679/7
- a = 97
- b= 5*97 = 485
- c = 100+ 97 = 197
Answer:
x = 5, y = 2
Step-by-step explanation:
First, find the value of x in respect to y:
2x + 3y = 16
2x = 16 - 3y
x = 8 - 3/2y
Then, substitute this expression into the second equation (Since we've established x is equal to 8 - 3/2y, we can put that in place of x):
4(8 - 3/2y) + 10y = 40
Then, distribute and solve for y:
32 - 6y + 10y = 40
32 + 4y = 40
4y = 8
<u>y = 2</u>
Now that we know what y equals, we can substitute the value of y in the equation to find x:
2x + 3(2) = 16
2x + 6 = 16
2x = 10
<u>x = 5</u>
Answer: each side is 1/8 yards long
Step-by-step explanation: since a square has four sides, and you have 1/4 yards of wood, 1/4 divided by 4 would equal 1/8.
True since each inch is 4 miles you time 6 by 4
false it says it is 12 miles so you divide that by 4 to get the inches
false if A to B is 24 and B to C is 12 miles there is clearly much more then 4 miles between A and C
