Answer:
X = 15
Step-by-step explanation:
We move all terms to the left:
<em>x+8+2x-(2x+13)=0</em>
We add all the numbers together, and all the variables:
<em>3x-(2x+13)+8=0</em>
We get rid of parentheses:
<em>3x-2x-13+8=0</em>
We add all the numbers together, and all the variables:
<em>x-5=0</em>
We move all terms containing x to the left, all other terms to the right:
<em>x=5</em>
Answer:
13
Step-by-step explanation:
So just find circumference is
circumfernce=2pir or pid
so diameter 2.5 ft
just for this problem aprox pi=3.14 so
c=pid
c=3.14(2.5)
c=7.85
a. 7.85 ft
b. how many times revolution till one mile (5280)
so
7.85 times x revolutions=5280
divide both sides b y7.85
x revolutions=672.61
round up so we complete the mile (about how many times..)
673 is the answer
a. 7.85 ft
b. 673 times
Answer:
<h2>juice = 21</h2><h2>lemonade = 28</h2>
Step-by-step explanation:
given:
ratio of juice and lemonade = 3:4
She needs to make 49 liters of punch for the party.

How much of each ingredient does she need
solution:
add the ratio 3 + 4 = 7
total punch divide by the total ratio
49 / 7 = 7 (coefficient)
juice 3 x 7 = 21
lemonade 4 x 7 =<u> 28 </u>
total = 49
