Answer:
Q1. No solutionQ2. (5, 6)Q3. Infinitely many solutionsQ4. No solutionQ5. (2, 3)Step-by-step explanation:
Q1.
y = -1/3x - 1x + 3y = -12Solution
x + 3(-1/3x - 1) = -12x - x - 3 = -12-3 = -12No solution
Q2
y = 2x - 4y = x + 1Solution
2x - 4 = x + 1x = 5y = 6(5, 6)
Q3
y = -3x + 36x + 2y = 6Solution
6x + 2(-3x + 3) = 66x - 6x + 6 = 66 = 6Infinitely many solutions
Q4
- 5x + y = 1- 10x + 2y = -2 ⇒ -5x + y = -1Solution
1 = -1No solution
Q5
y = 1/2x + 2y = x + 1Solution
1/2x + 2 = x + 11/2x = 1x = 2y = 3(2, 3)

ABCD is a parallelogram. If mZCDA = 63, then mZABC = _?_ The diagram is not to scale.
Answer:
b. 63
Step-by-step explanation:
A Parallelogram is known to be a flat shape quadrilateral which has four opposite sides Each two opposite sides are parallel and are equal in length. The opposite angles are equal.
The above answer is correct because opposite angles of a parallelogram are equal:
m∠CDA = m∠ABC
where m∠CDA = 63
∴ m∠ABC = 63 (answer)
Ali, Ben, and Cliff plant seedlings in their neighborhood park. Ali plants 40% of the total number of seedlings, Ben plants 45% of the total number of seedlings, and Cliff plants the rest of the seedlings. If Cliff plants 87 seedlings, how many seedlings do the three boys plant altogether?
Answer:
580 seedlings altogether.
Step-by-step explanation:
Given that,
Ali plants 40% of the total number of seedlings, Ben plants 45% of the total number of seedlings, and Cliff plants the rest of the seedlings. Cliff plants 87 seedlings.
The percentage of the seedling planted by Cliff = 100% - 45% - 40% = 15%
Let x = the total number of seedlings
[tex]15\%\ of\ x=87\\\\x=\dfrac{87\times 100}{15}\\\\x=580[/tex]
Hence, three boys plant 580 seedlings altogether.

1/2(6x - 10)-x+=? plz
Answer:
x=2.5
Step-by-step explanation:
1/2(6x-10)-x=0 Replace the ? with a 0 so you can solve for x.
So your going to want to distribute everything in parentheses by 1/2 first to get 3x-10-x=0 Next your going to simply the equation by combining like terms to get 2x-5=0. Next add five to both sides so that 2x=5. Finally divide both sides by 2 and the answer is x=2.5.

A stainless steel pipe is used as a vent over a restaurant stove. The pipe is 6 feet long and its diameter is 12 inches. The pipe is open at both ends. To the nearest whole number, how many square feet of steel is the outer surface of the pipe?
Answer: 18 feet
Step-by-step explanation:
Well, first we need to find the circumference because that is the outside of the pipe.
Circumference = 2 x Pi x Radius
Radius is half of diameter.
So we plug in all the values in to the formula.
2 x Pi x 6 inches = Circumference
12Pi = 37.69911184 inches
37 inches to feet = about 3 feet.
3 x 6 = 18 feet.
