Answer:
1:4
Step-by-step explanation:
Given
3: 12
To express in the form 1:n
Consider how to make 3 equal to 1, we simply divide 3 by 3 to get 1 as such, we would also divide 12 by 3
3:12
= 3/3:12/3
= 1:4
Comparing with 1:n, it is safe to say that n = 4
Use the distributive property:
5*b+5*2+b=20
5b+10+b=20.
Combine like terms:
6b+10=20.
Subtract 10 from both sides:
6b+10-10=20-10
6b=10.
Divide both sides by 6:
6b/6=10/6
b=5/3=1 2/3.
Brian travels 1 2/3 hours. This means Annie travels
5(1 2/3+2)=5(3 2/3)=5(11/3)=55/3=18 1/3 hours.
Hope this helps!
a = 1
x = 8
3x - y = 9
3(8) - y = 9
24 - y = 9
-y = 9 - 24
-y = -15
y = 15
ax + y = 23
a(8) + 15 = 23
8a = 23 - 15
8a = 8
a = 8/8
The answer to this question is: 44.
The even numbers that we can form with the numbers 2,4,5 and 8 are:
2, 4, 8, 22, 24, 28, 42, 44, 48, 52, 54, 58, 82, 84, 88, 222, 224, 228, 242, 244, 248, 252, 254, 258, 282, 284, 288, 422, 424, 428, 442, 444, 448, 482, 484, 488, 522, 524, 528, 542, 544 and 582, 584, 588.
1/2x-7
Add 3/8x and 1/8x to get 4/8x which is the same as 1/2xThen add the integers: -2 + -5 = -7.
