Answer:

A) f(2) = 20

B) g(2) = 2

C) f(2) + g(2) = 22

Step-by-step explanation:

For part A, you change the x to become 2, to have the equation of 5(2)+10. You then solve in order to get 20.

For part B, I'm not exactly sure what the equation is, but you do the same thing for part A. Since there is no x variable then just keep the answer you have. Meaning it is 2

Finally, part C is adding your answers from part A and part B to get the final answer of 22.

Marc is looking at the plans for his new garage. the length of the garage is 8 metres. the scale on the drawing is 1:50. what wi
evablogger [386]
The answer is 16 cm (or 0.16 m).

The scale is the ratio of the model to the real thing.
So, in the scale 1:50, the model is 1, while the real thing is 50.
Now, just make a proportion:
the model : the real thing = the model dimension : the real thing dimension
        1         :          50         =                   x                 :                    8m

From here:
x = 8m * 1 / 50 = 0.16 m = 0.16 * 100 cm = 16 cm.

Eli wants to plant 45 sunflower plants, 81 corn plants and 63 tomato plants in his garden. If he put the same number of plants i
Lynna [10]

Answer:

9

Step-by-step explanation:

For this problem, you would use the GCF

Find the GCF of 45, 81, 63

GCF(45, 81, 63) = 9

45 = 9 * 5

81 = 9 *9

63= 9 * 7

Since 5, 9, 7 have no common factors, the GCF has to be 9.

This means that the greatest number of plants he can put in each row is 9.

The number of rows he uses for each plant will (obviously) vary.
