If there’s 195 countries in the world and only 78 of them have food guides, what’s the % of countries with food guides?

40%

Step-by-step explanation:

You divide the part by the total and multiply the result by 100:

78/195 * 100 = 0.4 * 100 = 40%

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
