Answer:
2x + 4y = 14 = x= −2y+7
3x - 4y = -39= x= 4=3
y−13
Step-by-step explanation:
Hello,
The sum of the angles of a triangle is equal to 180°.
<u>So :</u>
x = 180 - 40 - 55 = 85°
Have a nice day :)
An independent variable is the variable that can be changed whilst the dependant variable cannot be changed to keep a fair test ✅
Since I can't draw the Venn diagram, I will solve it mathematically.
Let n be the number of drinkers:
n( lattes) = 16
n(espresso) = 12
n(elates AND espresso) = 8
Let's find the number of those who drink either latte or espresso)
n(Lattes OR espresso) = n(lattes) + n(espresso) - n(lattes AND espresso)
n(Lattes OR espresso) = 16 + 12 - 8 = 20
Then 20 likes either lattes or espresso + 8 likes both = 28 like coffee
The total is 50, out of them 28 like coffee, then those who don't like coffee are: 50-28 = 22 (answer B)
1 kilogram = 2.2 pounds.
Multiply the total kilograms by 2.2 to get total pounds.
31.5 kilograms x 2.2 = 69.3 pounds
