Three.
They've got the same denominator, so you can act like the nominators are whole numbers and simply divide those. Or...
×
Cross multiply, so 1 times 4 and 4 times 3.
And then divide to get 3.
Since all the terms are odd, the last four terms would be 115+117+119+121
115 + 117 = 232
232 + 119 = 351
351 + 121 = 472
Answer: 472

Answer:
Chef Rita can feed 20 people with 55 pancakes.
Step-by-step explanation:
We can solve this problem using equivalent ratios. Since we know that Chef Rita can feed 8 people with 22 pancakes, we can set up the ratio:
To solve how many people she would be able to feed with 55 pancakes, we can set ratios equal to each other and solve for 'x' which is the number of people.
We can see what factor we multiply 22 by to get 55 and then we multiply the denominator by the same factor to get our equivalent ratio. 55 ÷ 22 = 2.5. So, 8 x 2.5 = 20 people.
Answer: It's 129°
Step-by-step explanation: Because we know x and 51 are supplementary angles (add up to 180), We can do x + 51 = 180, to figure out that x is equal to 129°.
