how do I solve -3x+8y=18 and -x+y=-4
9514 1404 393
Answer:
(x, y) = (10, 6)
Step-by-step explanation:
Any of the usual methods work to solve this: elimination, substitution, graphing, matrix methods. For a "no-work" solution, I prefer a graphing calculator.
__
In the second equation, both x and y have coefficients of ±1, so substitution or elimination can be used with equal ease. Adding x to the second equation gives an expression for y that can be substituted in the first equation.
y = x -4
-3x +8(x -4) = 18
-3x +8x -32 = 18 . . . eliminate parentheses
5x = 50 . . . . . . . . . add 32, collect terms
x = 10 . . . . . . . . . . .divide by 5
y = 10 -4 = 6 . . . . . use the expression for y to find y
The solution is (x, y) = (10, 6).

Especial on a cruise to Atlantis is advertising is being eight nights of the regular price the regular price is $1827 what is the sales price price
Answer:
$14,616
Step-by-step explanation:
The computation of the sales price is shown below:
The regular price is $1,827
And it would be advertised having 8 nights of the regular price so here we assume that the sales price is 8 times of the regular price
so, the sales price is
= $1,827 × 8
= $14,616
John has 2,700 seeds of corn to plant in 9 rows on his farm. Each row will have the same number of seeds. Part A Which basic fact can John use to find out how many seeds will be planted in each row?
Answer: A. We will divide total seeds by the number of total rows.
300 seeds will be planted in each row.
Step-by-step explanation:
Given: Total seeds = 2700
Total rows = 9
If each row will have the same number of seeds.
Then, the number of seeds will be planted in each row = (Total seeds) ÷ (Total rows)
= 2700÷9
= 300
Hence, 300 seeds will be planted in each row.

Suppose that the height H of a Ferris wheel can be modeled by the function n H(t)= -16cos(t/45)+24, where t is the time in seconds. What is the maximum height of a cabin? Use 3.14 for π
Answer:
40 feet.
Step-by-step explanation:
The height of the Ferris Wheel is modeled by:
[tex]\displaystyle H(t)=-16\cos\Big(\frac{t}{45}\Big)+24[/tex]
Where H(t) is the height (in feet (assuming)) and t is the time in seconds.
Remember that the value of cosine, regardless of the input, will always be between -1 and 1. That is:
[tex]-1\leq \cos(t)\leq 1[/tex]
So, we can use the two maximums. Testing -1 and 1, we get:
[tex]H(t)=-16(1)+24=8[/tex]
And:
[tex]H(t)=-16(-1)+24=40[/tex]
Therefore, the maximum height of a cabin of the Ferris Wheel will be 40 feet in the air.
Notes:
And the minimum height will be 8 feet.
We are not asked to find t. To do so, however, set H(t) = 40 and find the general solution for t.

A 50 centimeter piece of wire is bent into a circle. What is the area of this circle?
Answer:
198.95 cm²
Step-by-step explanation:
Circumference = 50cm
C = πD
D = C/π
r = D/2
r = 50/π/2
r= 7.957747…..cm
Area = π r²
A = π x 7.957747….²
A = 198.95 cm² (2dp)

Answer:
The mean is 82.727272727273 rounded 83
Step-by-step explanation:
You add all the numbers:
40 + 75 + 80 + 80+ 81 + 84 + 88 + 90 + 92 + 100 + 100= 910
You divide that result by the total of numbers to add, in this case 11
910/11= 82.727272727273
To round any number, consider that if it is 5 or above it you can round it to the nearest hundred.
Just in case

A school club purchases sandwiches and pretzels for a lunch. Each sandwich costs $4.25 and each bag of pretzels costs $0.75. A total of 48 items (sandwiches and pretzels) were purchased for a total cost of $175. If s = the number of sandwiches and p = the number of pretzels, which system represents this situation?
A. s + p = 48
4.25s + 0.75p = 175
B. s + p = 175
4.25s + 0.75p = 48
C. s + p = 48
0.75s + 4.25p = 175
D. s - p = 48
4.25s + 0.75p = 175
Answer: I’m 95% sure it’s A

A 4-foot-long sandwich is cut into servings that are each foot long. How many
servings will there be after the sandwich is cut?
3
12
Answer: 4
Step-by-step explanation:
If the foot-long sandwhich is 4 feet long, and is cut into parts that are each 1 foot long, then we need to divide 4 by 1.
4 ÷ 1 = 4, so there will be 4 servings after the sandwich is cut.

A straight angle is broken into 3 angles. The first angle measures 38°, the second angle is a right angle. What is the measurement of the 3rd angle?
Answer: The measurement of the 3\large ^{rd} angle is
Answer:
52°
Step-by-step explanation:
Let the measure of the third angle be x°.
Since, straight line is broken into three angles. So, the sum of all the three angles will be equal to 180°.
38° + 90° + x = 180°
128° + x = 180°
x = 180° - 128°
x = 52°
Answer:
52°
Step-by-step explanation:
So, we basically know that,
A straight Angle=180°
When it has been broken into 3 pieces, we have gotten one which is 38°and a right angle.
Now , we know that
A right angle= 90°
So, we need to do,
Sum of known angles= 38+90=128°
Lastly,
Unknown angle = 180° - 128° = 52°

how many square feet of outdoor carpet will we need for this hole
Answer:
42 ft²
Step-by-step explanation:
First of all, who makes a hole in this shape?
Anyways,
You're going to want to split the figure into multiple different shapes. We already have a triangle, so I would split the remaining shape into a rectangle and trapezoid.
We can find the area of the triangle easily with the equation 1/2(bh)
So
1/2(2 · 3)
1/2(6)
3
So the triangle is 3 ft²
Now we can find the area of the rectangle.
The measurements will be 3 and 7. It's just base x height so it'll be 21 ft²
Finally the trapezoid.
Base 1: 6
Base 2: 3
Height: 4 (11-7)
Formula: 1/2h (b1 + b2)
1/2 · 4 (6+3)
2(9)
18 ft²
Now just add them together:
3+21+18=42
Hence, your answer is 42 ft²
