9:14 and a:7 are equal ratios 14/2=7 and 9/2=4.5 so the answer is 4.5
Answer:
m<3 = 70 and m<4 = 110
Step-by-step explanation:
<3 and <4 are vertical angles so they add up to 180
(3y + 7) + (5y + 5) = 180
(3y + 5y) + (7 + 5) = 180
8y + 12 = 180
-12 -12
8y = 168
/8 /8
y = 21
find the angle measures:
3(21) + 7
63 + 7
70
5(21) + 5
105 + 5
110

B.
200x + 800 = 1,600; 4 months
Step-by-step explanation:
Since 200 is the amount you pay each month, and x is the months, we pay 200 dollars for each month. We also add 800 because that was the initial price she paid, which is known. We then complete the equation by making it equal to 1600 dollars, which is the total amount she paid.
When we get 200x + 800 = 1,600, we solve for x.
First, we minus 800 on each side to isolate x. 200x=1600-800
Then, we simplify, 200x=800
Lastly we divide by 200 on both sides to completely isolate x and complete the equation. 200x=800÷200
Simplify, getting x=4 (months)

Answer:
10\frac{7}{12}
Step-by-step explanation:
First thing you want to do is find the common denominator for \frac{1}{3} and \frac{3}{4}. You do this by multiplying to denominators together, so 3*4=12.
Next, multiple the numerators with the opposite denominator. 1*4=4 and 3*3=9.
Now you are left with \frac{4][12] and \frac{9}{12}.
Add those back to your numbers
16\frac{4}{12} - 5\frac{9}{12} = 10\frac{7}{12}
