Answer:
337.5 and also 202.5
Step-by-step explanation:
do 8x = 540 since 5 and 3 are in a ratio... so you get 5x plus 3x. Then you solve for x and get 67.5..67.5 times 3 is 202.5 and 67.5 times 5 is 337.5.
Hi there!

f(x) = -2x - 3
Plug in 0 for "x" to solve for f(0):
f(0) = -2(0) - 3
f(0) = -3
Since the question is asking you to evaluate f(0) - 7, simply subtract:
-3 - 7 = -10.
{x+2y+2z=0
{2x+y+z=3
{x-3y-z=1
{x+2y+2z=0
-
{4x+2y+2z=6
{-3x=-6 → x=2
{-3y-z=-1
+
{y+z=-1
{-2y=-2 → y=1
{2+2+2z=0 → 2z=-4 → z=-2
Final triple is
(2; 1; -2)
Answer:
(1/3)(n - 4) = 1/6
Step-by-step explanation:
Let the number be n. Then the given phrase can be written symbolically as (1/3)(n - 4) = 1/6. This is the second answer choice.
