The answer is B, or 2x + 3y - 5 = 0. This is because when you substitute both points in for x and y, you get the values of 0=0, which is true!
Answer:
196 minutes
Step-by-step explanation:]
2x10 is 20 and if you divide 5/10 its 2 so the 4 in 4/5 is the total of 8 because 10 would mean 5/5 and 20+8=28 so 28x7 is 196
Step-by-step explanation:
If you mean 5 + 3 over 4, then:
5 + 3/4 = 5 3/4.
_________________________________
If you mean 5 + 3 divided by 4, then:
5 + 3 = 8
8 divided by 4 = 2.
Answer:
67.5°, 107.5°
Step-by-step explanation:
For supplementary angles, their sum equals 180°.
Let x be the first angle and y be the second angle, then
x + y = 180°.
It is given that x = y + 45°.
So x + y = 180°
substituting x into the equation, we have
y + 45° + y = 180°
simplifying, we have
2y + 45° = 180°
collecting like terms, we have
2y = 180° - 45°
2y = 135°
dividing through by 2, we have
y = 135°/2
y = 67.5°
Since y = 67.5°
then x = y + 45°
x = 67.5° + 45°
x = 107.5°
In this question, each package has 8 notecards.
one notecard costs $8
2 notecards cost $16
3 notecards cost $24
if n - number of packages
d - selling price in dollars
We can see that with each additional notecard bought the cost increases by $8
therefore there's a proportional relationship between n and d
As n increases, d increases by the same amount.
if we put it in an equation,
d = 8*n
n - 1 package and d is 8
if n - 2
d = 8*2
d = 16
Therefore we can use the following equation;
d=8n
