Answer:
y = 3
Step-by-step explanation:
y/9 = 2/6
y/9 = 1/3 (dividing by 2in both numerator and denominator.)
CROSS MULTIPLYING WE GET
3y = 9*1
3y = 9
y = 3
Answer:
$969.04
Step-by-step explanation:
now at age of 18 Brad has 1500 * 1,065^18
at age of 21 he will have 1500 * 1,065^21
if he waits the difference will be 1500 * 1,065^21 - 1500 * 1,065^18 = $969.04
Answer:
12
Step-by-step explanation:
First figure the ratio of the real building to the model which is 21 divide 3. So the ratio is 1:7, since we're finding the height of the model, we divide 7 by 84 which is 12
F(x) = x² + x - 20 = x² + 5x - 4x - 20 = x(x + 5) - 4(x + 5) = (x + 5)(x - 4)
f(x) = 0 ⇔ (x + 5)(x - 4) = 0 ⇔ x + 5 = 0 or x - 4 = 0 ⇒ x = -5 or x = 4
Answer: C. x = -5 and x = 4.
It there are 2 rows of 8 chairs all you have to do is add 8+8 which equals 16
Unless it means there are 8 chairs altogether split into 2 even rows then you do 8\2 =4
I would write down both answers if your not sure which one it is :)
