To solve this problem you must apply the proccedure shown below:
1. Let's call: the number of roses and the number of lilies.
2. You must make a system of equation based on the information given in the problem above:
3. Use the method of substitution. First, solve for in the second equation, then substitute it into the first equation, and then solve for :
4. Now, substitute into the second equation:
Therefore, the answer is: roses and lilies.
Answer:
when dividing fractions folow these steps:
first, you need to switch the denom and num of the second fraction:
3/4 ÷ 1/3---> 3/4 ÷ 3/1
Next you just switch the sign of the negative to a multiplication sign and multiply:
3/4 ÷ 3/1---> 3/4 x 3/1
3/4 x 3/1 -----> 9/4
9/4, 2 1/4 - these are your answers. Either are correct

Answer:
A Mudslinger tire weighs 20.71 pounds and a Roadripper tire weighs 19.52 pounds
Step-by-step explanation:
Let the weight of a Mudslinger tire=m
Let the weight of a Roadripper tire=r
4 Mudslinger tires and 6 Roadripper tires weigh 200 pounds
4m+6r=200.....(i)
7 Mudslinger tires and 2 Roadripper tires weigh 184 pounds
7m+2r=184....(ii)
To find the values of m and r, we solve the two derived equations simultaneously.
4m+6r=200.....(i)
7m+2r=184....(ii)
Multiply (ii) by 3 to get (iii)
21m+6r=552....(iii)
4m+6r=200.....(i)
SUbtract (i) from (iii)
17m=352
m=352/17=20.71 pounds
Substitute m=20.71 in (i)
4(20.71)+6r=200
6r=200-82.84=117.16
r=117.16/6=19.52 pounds
Answer:
The solution is (-17,80.5) and (1,8.5)
Step-by-step explanation:
Equation 1 :
Equation 2:
Substitute the value of y from equation 2 in equation 1
Equation 1 :
After substitution :
Substitute the value of x = -17
y = -4x+12.5
y = -4(-17)+12.5
y=80.5
Substitute the value of x = 1
y = -4(1)+12.5
y=8.5
Hence the solution is (-17,80.5) and (1,8.5)
Answer:
Step-by-step explanation:
If I have 90 pounds shared between A, B, and C, then in a mathematical equation,
A + B + C = 90
However, we have way too many unknowns.
We are told that the ratio of A to B is 1 to 2, or
and cross multiplying,
2A = B or
We are also told that the ratio of B to C is 4 to 3, or
and cross multiplying,
3B = 4C or
Now we have everything in terms of B, so we will rewrite it like that:
, and
and
9B = 360 so
B = 40. If B is 40 and A is half of B, then A is 20.
