=2y^2 - 3y^2 - y^2 + 3yz - yz - z^2 + 6zy ( arranging the like terms )

= -2y^2 + 2yz - z^2 + 6z ( simpliflying the like terms and leaving the unlike terms same as it is rule )

Over the summer, for every 12 okra seeds Dana planted, 7 grew into plants. If he planted 156 okra seeds, how many grew into plan

drek231 [11]

Set this up as a proportion with seeds on top and plants on bottom. Ours will look like this: $\frac{12}{7}= \frac{156}{x}$ . Cross multiply to get 12x=1092. Divide to get that the number of plants to expect from 156 seeds is 91, choice B from above.

1. A farmer is planting a 47-acre field of green beans. How many seeds must be purchased if the farmer plants 140,000 seeds per

Sedaia [141]

Answer:

Step-by-step explanation:

There are 47 acres and the farmer is planting 140,000 per acre.

You got to times 140,000 by 47 but you can multiply 14 by 47 instead and place the zero later.

So take 10 times 47 and that is 470

Then take 4 times 47 and that is 188

Add 470 and 188 and you get 658

Take 658 a place the four zeros and you get 6,580,000 seed

The ratio of red cars to blue cars in a parking lot was 5 : 3. If there were 40 red cars, how many blue cars were there?

Ne4ueva [31]

Answer:

24 blue cars

Step-by-step explanation:

In this problem, one is given the ratio of red to blue cars in the parking lot. One is given the actual number of red cars, and one is asked to find the number of blue cars. One can set up a proportion; ratio to actual, then solve to find the number of actual blue cars using the method of cross-products. One can set up the proportion using the ratios, but it is easier to express the proportion as the equality of two fractions. Thus, the following equation can be formed, let the parameter (x) represent the actual amount of blue cars;

$\frac{red}{blue}= \frac{5}{3} = \frac{40}{x}$
