We know by definition that complementary angles add up to 90 degrees. We can set up an equation using the ration given:
17x+13x=90, with x representing the amount you need to multiply the ratio by to get 90.
17x+13x=90
30x=90
x=3
We now know that the number we multiply the ratio by is 3. The smaller number in the ratio is 13, and so therefore we multiply it by 3.
3*13=39
The answer is 39 degrees.
It’s easy just find the slope and the answer is gonna be obvious
Slope= y2-y1/x2-x1
Slope = -2-(-1)/0-4 = -1/-4 = 1/4
Slope = 1/4x
So the answer should be C
Answer:
cost of each sub = $6, delivery fee = $2
Step-by-step explanation:
Let $x be the cost of each sub and $c be the delivery fee
3x + c = 20
4x + c = 26
x = 6, c = 2
Answer:
-108
108
Step-by-step explanation:
Since it is withdrawing, we are taking away -$18 every day for 6 days.
(-18)*6 = -108
Since it is deposits, we are adding to the amount in her account, +$18 for 6 days.
18*6 = 108
The difference is that one is taking away and one is adding each day, resulting in negative or positive change.
