X + y = 61
y - 3x = 5...y = 3x + 5
x + (3x + 5) = 61
4x + 5 = 61
4x = 61 - 5
4x = 56
x = 56/4
x = 14
y - 3x = 5
y - 3(14) = 5
y - 42 = 5
y = 42 + 5
y = 47
ur 2 numbers are 14 and 47
B is related to the last term of trinomial
Last term on the left hand side of the equation = Last term on the right hand side of the equation.
The last term on the right hand side is gotten by multiplying all the terms on the right of the two expression.
-32y²= 2*-8y*By
-32y² = -16By² Compare both
32 = 16B
16B = 32
B = 32/16
B = 2.
Answer:
b.
Step-by-step explanation:
that one is easy
Answer: 2 and 17/20 mm is the total thickness of the stack.
Step-by-step explanation:
Get the values you need for the dime and the penny from the chart:
dime: 1 and 7/20mm , penny: 1 and 1/2mm
Find common denominators for the fractions given in the chart.
20 will work because 1/2 is the same as 10/20.
Add the numerators of the fractions: 7 + 10 = 17 so the fraction will be 17/20
Add the whole numbers 1 + 1 = 2
Put it all together and now you've got 2 and 17/20 mm
