Answer: ![m\angle 2+m\angle 5=180^{\circ}](https://tex.z-dn.net/?f=m%5Cangle%202%2Bm%5Cangle%205%3D180%5E%7B%5Ccirc%7D)
Step-by-step explanation:
You are ending by proving
and
are supplementary, so right before that, you need to prove their measures add to 180 degrees.
Ok sooo if you get the exponents all together and then divide then you should get your answer but since you’re on here and you need it then I’ll give it to you : f(x)=4 ; sine the past (x)2years there has been f(x) 4 times as much as lions.
Question 2) 6y - 1 = 5
First we need to add 1 to each side.
6y - 1 + 1 = 5 + 1
6y = 6
Then we will divide each side into 6 groups.
6y/6 = 6/6
y = 1
Question 4) 3t - 1 = 8
First we need to add 1 to each side.
3t - 1 + 1 = 8 + 1
3t = 9
Then we will divide each side into 3 groups.
3t/3 = 9/3
t = 3
Answer:
10 liters of orange juice, 5 liters of champagne
Step-by-step explanation:
We can call the amount of orange juice and champagne as x and 15 - x liters respectively. Then, we can write the following equation:
1.50 * x + 12 * (15 - x) = 5 * 15
1.5x + 180 - 12x = 75
-10.5x + 180 = 75
-10.5x = -105
x = 10 so 15 - x = 15 - 10 = 5.
Answer:
5. Katelyn worked 11 hours at the grocery store.
6. 5pounds of steak
Step-by-step explanation:
5. let x hrs be the no. of hours Katelyn worked at the grocery store.
amnt of money she earnt = 9x + (15-x)×15
= 9x -15x + 225
= -6x + 225
-6x + 225 = 159
6x = 225-159
6x= 66
x= 11
Katelyn worked 11 hours at the grocery store.
6. Let x be the pounds of steak he purchased.
total paid= 13.50x + (8-x)×3.25
= 13.50x -3.25x +26
= 10.25x +26
10.25x+ 26=77.25
10.25x = 77.25-26
10.25x= 51.25
x=5
