Solve tree he system of equations by the substitution method.
12x + 3y =8
-4x = y + 8
Answer:
8x + 2y
Step-by-step explanation:
12x + 3y = 8 you need to transfer the no. 8 to left since it's positive, it will be negative once you tranfer that and the result is this 8x + 3y -8 =0. Then do it again on the second given, -4x = y + 8.
Tranfer the y variable to left, y is positive then it will be a negative. No need to transfer the no. 8. Then the result would be -4x - y + 8=0
To this solve this, wrote it like this:
12x + 3y –8
-4x - y + 8
——————
8x + 2y

Answer:a) Which of the shapes is a heptagon?
Step-by-step explanation:a) Which of the shapes is a heptagon?
Anyone know this?? Question: find the area of the shape. Don’t forget your units and use 3.14 if you need to use pi.
Area of this shape = 614²
Answer with steps :Length of side of the first square = 10
It's area :
[tex] =\tt side \times side[/tex]
[tex] = \tt10 \times 10[/tex]
[tex] = \tt {100}^{2} [/tex]
Thus, the area of the first square = 100²
Length of the side of the second square = 10
It's area :
[tex] = \tt \: side\times side[/tex]
[tex] =\tt 10 \times 10[/tex]
[tex] = \tt{100}^{2} [/tex]
Thus, the area of the second square = 100²
Length of the side of the third square = 10
It's area :
[tex] =\tt side \times side[/tex]
[tex] = \tt 10 \times 10[/tex]
[tex] = \tt {100}^{2} [/tex]
Thus, the area of the third square = 100²
(pi value = 3.14)
Radius of the first semicircle = 10 cm
It's area :
[tex] = \tt \: \frac{\pi {r}^{2} }{2} [/tex]
[tex] = \tt \frac{3.14 \times 10 \times 10}{2} [/tex]
[tex] = \tt\frac{3.14 \times 100}{2} [/tex]
[tex] =\tt \frac{314}{2} [/tex]
[tex] =\tt {157}^{2} [/tex]
Thus, the area of the first semicircle = 157²
Area of the second semi circle :
= area of the first semicircle
= 157²
Thus, the area of the second semicircle = 157²
Total area of the figure :
= Area of the 3 squares + Area of the two semi circles
[tex] =\tt 100 + 100 + 100 + 157 + 157[/tex]
[tex] = \tt300 + 314[/tex]
[tex] = \tt {614}^{2} [/tex]
Therefore, the total area of the figure = 614²

Colton has 888 comedy movies, 666 action movies, 555 fantasy movies, and 111 drama movie on his list of favorite movies. For every 555 movies on the list, there are 222 \_\_\_\_____\_, \_, \_, \_ movies.
Answer: Comedy
Step-by-step explanation:
Find out the percentages of each of the movies. First find the total quantity.
= 888 + 666 + 555 + 111
= 2,220 movies
Comedy = 888/2,220 * 100% = 40%
Action = 666 / 2,220 * 100% = 30%
Fantasy = 555/2,220 * 100% = 25%
Drama = 111/ 2,220 * 100% = 5%
222 movies out of 555 is:
= 222 / 555 * 100%
= 40%
222 movies out of 555 movies will therefore be comedy.
Answer:
222/555 are comedy

what is this 59 divided 535
Answer:
9.07 [Rounded]
Step-by-step explanation:
535 divided by 59 is 9.07, which I rounded.
The value of the division 535 ÷ 59 is 9 with a remainder of 4 and the decimal form can be expressed as 9.067.
To find the value of division 535 ÷ 59, we can perform a long division.
To perform the calculation, we can use long division:
59 ) 535 ( 9
- 531
______
4
Divide the first digit of the dividend (5) by the divisor (59). Since 5 is less than 59, we bring down the next digit, making it 53.
Divide 53 by 59. The result is 0, as 53 is less than 59.
Bring down the next digit, making it 535.
Divide 535 by 59. The result is 9, as 59 can go into 535 nine times.
Multiply 9 by 59, which equals 531.
Subtract 531 from 535, which gives us a remainder of 4.
Therefore, the value of the division 535 ÷ 59 is 9 with a remainder of 4.
In decimal form, the division can be expressed as 9.067, indicating that 59 goes into 535 nine times with a remainder of 4.
