Answer: T=1/2 Y + -5/2
Step-by-step explanation:
y=2t+5
2t+5 +-5= y +-5
2t=y-5 2t/2=y-5/2
t=1/2y+-5/2
= t=1/2y + -5/2
Answer:
x=7
Step-by-step explanation:
Opposite of subtraction is adding so you do 4+10=14 so that means that x equals seven because 2x7 equals 14.
Answer:
A
Step-by-step explanation:
The median AB bisects DC at right angles ,hence BD = 4
Using Pythagoras' identity on the right triangle ABD
The square on the hypotenuse AD is equal to the sum of the squares on the other 2 sides, that is
AB² + BD² = AD², that is
AB² + 4² = 5²
AB² + 16 = 25 ( subtract 16 from both sides )
AB² = 9 ( take the square root of both sides )
AB = 
= 3 feet → A
STEP 1:
convert gallons to cups & calculate total number of cups
1 gallon= 16 cups
= 8 gallons * 16 cups/gallon
= 128 cups total
STEP 2:
calculate total cups estimated for 20 guests
= 20 guests * 2 cups/guest
= 40 cups needed for guests
STEP 3:
subtract the difference between step 1 and step 2 to find leftover punch
= 128 cups - 40 cups
= 88 cups leftover
OR
GALLONS LEFTOVER
= 88 ÷ 16 cups/gallon= 5 1/2 gallons
ANSWER: There will be 88 cups or 5 1/2 gallons of punch leftover.
Hope this helps! :)
