-6^2 - 28/4 + (-9)
Multiply -6 by it's exponent.
36 - 28/4 + (-9)
Divide 28 by 4
36 - 7 + (-9)
Subtract 7 from 36.
29 + (-9)
Add -9 to 29. This would be the same as subtracting 9 from 29(29-9).
Final Answer: 20
Answer:
6 , 2 , 5 , 7 , 4 , 1 , 3
Step by Step:
1) x - 3(10 - 2x) = -2
x - 30 + 6x = -2
7x - 30 = -2
7x = 28
x = 4
2) x + 2(4 - 2x) = 5
x + 8 - 4x = 5
-3x + 8 = 5
-3x = -3
x = 1
3) 5(18 - 4y) + y = 33
90 - 20y + y = 33
90 - 19y = 33
-19y = -57
y = 3
x = 18 - 4(3)
x = 18 - 12
x = 6
4) 8x + 4(13 - 2x) = 52
8x + 52 - 8x = 52
52 = 52
5) x + 3(-11 + 6x) = 5
x - 33 + 18x = 5
19x - 33 = 5
19x = 38
x = 2
6) -6(5 - 2y) - 3y = -2
-30 + 12y - 3y = -2
-30 + 9y = -2
9y = 28
y = 3
2x + 3(3) = 5
2x + 9 = 5
2x = -4
x = -2
7) 2x + 3(10+x) = 45
2x + 30 + 3x = 45
5x + 30 = 45
5x = 15
x = 3
9/12 matches to 3/4 For questions like this I like to use apps like Socratic, it shows answers from multiple sites and can solve almost any question.
Answer:
15ft by 18ft
Step-by-step explanation:
Start with 2.5 divided by .25
That equals 10
10 times 1.5 ,because we know it takes ten .25inches to equal 2.5 and 2.5, is the size of one of the sides.
10 time 1.5 is 15ft
3 divided by .25 is 12
using the same logic and math as stated above we know 3 x .25 equals 12 by 12 quarter inches to make 3 inches
12 x 1.5 Same logic as before
12 x 1.5 equals 18ft
The kitchen is 15ft by 18ft
