R= 5
You divide -7 by both sides to 1. Cancel out the -7 2. To simplify the -35. So simplified -35/-7=5
Hello! We can go ahead and eliminate C and D, because those answers don't make any sense. There are 2 cups in 1 pint and there are 4 pints. 2 * 4 is 8. There are 8 cups in 4 pints. The cost for that much ice cream is $16.39. To dins the cost per cup, let's divide that number by the number of cups, which is 8. 16.39/8 is 2.04875 or 2.05 when rounded to the nearest hundredth. The cost for a cup of ice cream is $2.05. The answer is A: $2.05.
Perimeter = 72m
length = x
width = x - 4
P = 2l + 2w
72 = 2x + 2(x - 4)
72 = 2x + 2x - 8
72 = 4x - 8
72 + 8 = 4x
80 = 4x
80/4 = x
x = 20
Therefore, the length = 20m and width = 16m
X + 3y = 7
x = -3y + 7
2x + 4y = 8
2(-3y + 7) + 4y = 8
-6y + 14 + 4y = 8
-2y = 8 - 14
-2y = - 6
y = -6/-2
y = 3
x + 3y = 7
x + 3(3) = 7
x + 9 = 7
x = 7 - 9
x = -2
solution is (-2,3)
