Answer:
The answer should be 8. Hope this help you out.
Answer:it should be true
Step-by-step explanation: for example 2+2c^2=18 18-2 is 16 divide by 2 then square root this etc
Answer:
It should be also zero because it is zero
{-2x + 7y = -5
{-2x - 4y = 6 | · (-1)
{-2x + 7y = -5
{2x + 4y = -6 (+)
----------------------------------
-2x + 2x + 7y + 4y = -5 + (-6)
11y = -11 | : 11
y = -1
{y = -1
{2x + 4y = -6
{y = -1
{2x + 4 · (-1) = -6
{y = -1
{2x - 4 = -6 | + 4
{y = -1
{2x = -2 | : 2
{y = -1
{x = -1
Answer:
Step-by-step explanation:
a) We're working with the ratio 3:1
x:500
500/1 = 500
500 * 3 = 1,500
x = 1,500
She would need to use 1,500 mL of yellow ink.
b) We're working with the ratio 2:3
x:750
750/3 = 250
250 * 2 = 500
x = 500
She would need to use 500 mL of red ink.
You can check both of these by:
(a) 1,500/500 = 3/1 = 3 : 1 which is the ratio we're working with.
(b) 500/2 = 250
750/2 = 375
250 : 375
Then, divide both 250 and 375 by 125
250/125 = 2
375/125 = 3
We are then left with the ratio 2 : 3 which is the ratio we're working with.
