Answer:
3. It's b and c 4. total number of participants in marathon=99+121=220 percentage of female = 121/220×100 =55% 5. the answer is 7
Step-by-step explanation:
The dividend of the given expression above is,
3d² + 2d - 29
and its divisor is equal to d+3. The steps in the long division are written below.
1. First, divide the first term of the dividend (3d²) by first term of the divisor (d). This gives us 3d.
2. Next, multiply the answer, 3d, by the divisor (d+3). This gives us 3d² + 9d.
3. Then, subtract the answer, 3d² + 9d from the dividend, 3d²+2d-29. This gives us,
-7d - 29
4. Next, divide the first term of -7d by the first term of the divisor, d. This gives us the answer of -7.
5. Next, multiply the answer, -7, by the divisor, d+3. This gives us -7d-29
6. Then, subtract the answer in step 5 from the answer in step 3. This gives us,
-7d-29 - (-7d-39) = 0
7. Combining the answer in steps 1 and 4 for the final answer will give us the answer of
3d-7
<em>Answer: 3d-7</em>
Answer:
(2,1)
Step-by-step explanation:
Step-by-step explanation:
According to rules of Proportionality :

(A) When (a = 10, b = 8, c = 2)
K = 5
(B) When (b = 20, c = 5)

70% of the total distance is 210 miles...
0.70x = 210
x = 210/0.70
x = 300....so the total distance is 300 miles
and if he traveled 210 miles, and the total distance is 300 miles, then he would have (300 - 210) = 90 more miles to go to reach grandpa
