Answer:
Step-by-step explanation:
Given system of equations:
To solve by the method of substitution, substitute the first equation into the second equation and rearrange so that the equation equals zero:
Factor the quadratic:
Apply the <u>zero-product property</u> and solve for x:
Substitute the found values of x into the <u>second equation</u> and solve for y:
Therefore, the solutions are:
Conversion.
1 yard = 3 feet
So the fabric has 2 yards. Then the size of the patch is 1/4 foot.
So the number of patches that Marcus used is..
= 3 * 2
= 6 / (1/4)
= 24 patches.
So a total of 24 patches Marcus used.
Answer:
1. 75%
2. 20%
3. 20%
4. decrease 5.4%
Step-by-step explanation:
1. 119-68=51, 51/68=0.75
2. 30-24=6, 6/30=0.20
3. 18-15=3, 3/15=0.20
4. 762-721=41, 41/762=0.0538
Answer: I believe the 23rd, but if its in 10 years I must be wrong
I graphed the equation, but replaced t with x
Theorems are proven with geometric proof
