If 2a = -10, that means a = -5 Because 2(-5) makes -10.
Thus, -6(-5) = 30 #
Therefore, -6a = 30
Answer:
Volume = 162 cm
Step-by-step explanation:
multiply 9x9x2
Exponential functions have a horizontal asymptote. The equation of the horizontal asymptote is
y=0.
So,
The secret to solving problems with ratios is to find the value of one unit.
5:7 = 12 units total
To find one unit, divide the total number of students by the total number of units.
600/12 = a
Simplify
50/1 = a
50 = a
The value of each unit is 50.
Now, multiply the units by the numbers in the ratio.
50(5) = b
250 = boys
50(7) = x
350 = x
There are 350 girls.
Answer:
x = 10
Step-by-step explanation:
y = 2x + 1
21 = 2x + 1
21 - 1 = 2x
2x = 20
x = 10
