Well, I believe you can set up a proportion for this. So:
d/c = d/c or 8/9 = x/6
*cross multiply*
9x = 48
*divide both sides by 9 to get x by itself*
x = 5 1/3
Answer:
260.55682 mL
Step-by-step explanation:
Given :
(1 lb =454 g, 1 L= 1.0567 qt, 4 cups=1 qt, 1 L=1000 mL)
1 pounds of coffee beans = 50 cups of coffee
Number of mL of coffee that can be obtainwd from 10 g of coffee beans
1 pound = 454g
10 * 50 cups = 500 cups / 454 = 1.1013215 cups
1.1013215 / 4 = 0.2753303 qt
0.2753303 qt / 1.0567 qt = 0.2605568 L
0.2605568 L * 1000 = 260.55682 mL
Answer:
D. false; if a = 1, b = 2, and c = 3, then 1(2 + 3) ≠ 1(2) + 2(3)
Step-by-step explanation:
A is false, because the a is being distributed/ being multiplied to all terms inside the parenthesis, and not the term b.
B is also false. There is no indicated negative signs.
C is also false because 1(1 + 1) is EQUAL to 1(1) + 1(1)
D is true.
we know that
a) 
gallon is equal to 
quarter of gallon
so
by proportion
gallons is equal to
quarter of gallon
b) liter is equal to 
quarter of gallon
by proportion
quarter of gallon is equal to
liters
therefore
the answer is the option
Answer:
Step-by-step explanation:
∠A + ∠B = 180 {supplementary angles}
8x - 25 + 7x - 5 = 180 {bring the like terms together}
8x + 7x - 25 - 5 = 180 {add the like terms}
15x - 30 = 180 {add 30 to both the side}
15x = 180 +30
15x = 210 {divide both sides by 15}
15x/15 = 210/15
x = 14
∠B = 7x - 5 = 7*14 - 5
= 98 - 5
∠B = 93°
