Answer:
X = -1 & and for some additional information Y = -5
Step-by-step explanation:
6 x (-1) = (-6)
5 x (-5) = (-25)
(-6) - (-25) = (-31)
_____________
5 x (-1) = (-5)
3 x (-5) = (-15)
(-5) + (-15) = 10
Answer:
x = -1
Step-by-step explanation:
Rashid may have used elimination to solve the problem, but we can use any method we like to find the correct value of x. One method we like is graphing. The attached graph shows the solution is (x, y) = (-1, 5), so we know Rashid found ...
x = -1
__
If we go down Rashid's path, we multiply the first equation by 3 and add that to the second equation multiplied by 5. (This choice of multipliers results in a positive coefficient for x.)
3(6x -5y) +5(5x +3y) = 3(-31) +5(10)
18x -15y +25x +15y = -93 +50 . . . . . . eliminate parentheses
43x = -43 . . . . . . . . . . . . . . . . . simplify
x = -1 . . . . . . . . . . . . . . . . . divide by 43

Answer:
Step-by-step explanation:
1) Area of triangle= 1/2 x b x h
b = 7.6cm h= 3.4cm
Area= 1/2 x 7.6 x3.4 = 12.92cm²
2)Divide the shape into a triangle and a rectangle
Area of rectangle : l x b
L= 20cm, b= 7cm
= 20 x 7 = 140 cm²
Area of triangle =1/2 x b xh
B = 20cm, h= 16 - 7 = 9cm
1/2 x 20x 9= 90cm²
Total area = 140 + 90 = 230cm²
3) area of triangle = 1/2 x b x h
B = 12cm, h= 5cm
= 1/2 x 12 x 5 = 30cm²
4) area of triangle = 1/2 x b x h
B = 15cm, h= 8cm
= 1/2 x 15 x 8 = 60cm²
5) divide the shape into two rectangles; the lower and the upper
Area of rectangle= l x b
Upper rectangle, l= 10cm, b= 27 - 9 = 18cm
Area= 10 x 18= 180cm²
Lower rectangle, l= 24cm, b= 9cm
Area = 24 x 9= 216cm²
180 + 216 = 396cm²

Miguel's mother builds and sells houses. She wants to buy a piece of land on which to build several houses. There are two lots for sale. One is a rectangular plot that is 3/8 of a mile by 2/3 of a mile. The other square plot that is 2/5 of a mile.
Part A
Which lot should Miguel's mother buy if she wants the biggest lot?
Part B
If the land in the area sells for 750,000 a square mile, how much should she expect to pay?
Answer:
Square lot and 187500
Step-by-step explanation:
To find question number A, we can calculate the area of each lot. The square plot is:
2/5×2/5=4/25
The first one is
2/3×3/8=1/4
Then we can make both have the same denominator:
1/4=25/100, 4/25=16/100
That means that the square lot is bigger.
We know that the area is 1/4 square mile. So it's 1/4 of 750,000
That's
1/4×750000=187500
Hope that helps! :)
there is a bag filled with 6 blue and 5 red marbles.
a marble is taken at random from the bag the colour is noted and then it is replaced. another marble is taken at random. what is the probability of getting 2 reds
Answer:
Step-by-step explanation:
The probability of obtaining a red marble in one sample is 5/11. Since you are sampling twice the probability of picking a red marble both times is 5/11 x 5/11 = 25/121. That is slightly less than one time in five.

The 5th term of an arithmetic sequence is 30, while the 13th term is 70
Answer:
a = 10
d = 5
Step-by-step explanation:
[tex]a_{n}=a + (n-1)d\\\\a_{5}=30\\\\a + (5-1)*d=30\\\\[/tex]
a + 4d = 30 ------------------(I)
[tex]a_{13}=70\\\\a + (13-1)d=70[/tex]
a + 12d =70 -------------(II)
Multiply equation (II) by (-1) and then add.So, 'a' will be eliminated and you can find the value of d
(I) a + 4d = 30
(II)*(-1) -a - 12d = -70 {Now add}
- 8d = - 40
Divide both sides by (-8)
d = -40/-8
d = 5
Plugin d = 5 in equation (I)
a + 4*5 = 30
a + 20 = 30
a = 30 - 20
a = 10

Angle A and B are shown to be the same which means the 2 sides are the same. Using the 2 sides solve for x.
2x -24 = x-2
Add 24 to both sides
2x = x + 22
Subtract x from both sides:
X = 22
Bc = x , so BC = 22

Answer:
8000 (Estimated) and the real difference would be 7934
Step-by-step explanation:
An estimated difference would be 8000, we get this number by subtracting 23,000 from 31,000 to make the subtraction much faster. The real answer to this would be 7934 which is pretty close to 8000 which is the estimation

What is 7/8 divided by 2/8
Answer:
7/8 ÷ 2/8 = 3 1/2
Step-by-step explanation:
When we divide two fractions, such as 7/8 ÷ 2/8, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
The quotient obtained from the division of given fractions is 7/2.
Given that, 7/8 divided by 2/8.
Dividing fractions is nothing but multiplying the fractions by reversing one of the two fraction numbers or by writing the reciprocal of one of the fractions. By reciprocal we mean, that if a fraction is given as a/b, then the reciprocal of it will b/a.
Here, 7/8 ÷ 2/8
= 7/8 × 8/2
= 7/2
Therefore, the quotient obtained from the division of given fractions is 7/2.

(b) If a line is parallel, the slopes will be the same. If they are perpendicular, the slopes will be are negative reciprocals of one another. If they are neither, then their slopes don't match up in any way.

Note - Since 1 & 2 are parallel, then both 1 and 2 will be perpendicular to 3!
