Tom ate 1/4 pizza, so that left him with 3/4 pizza.
Now that 3/4 is divided into 1/12 , so now he got 3/4 : 1/12
= 9 slices of 1/12 pizzas , or 9/12 of the original pizzas
Now it remained 1/6 or 2/12 of the original pizzas.
which mean, the amount of friends that got pizza are : 9 - 2 = 7 friends
hope this helps
Answer:
Step-by-step explanation:
log3^(2x+3) = log243
(2x+3)log3 = log243
2x+3 = log243/log3
2x = (log243/log3)-3
x = [(log243/log3)-3]/2
x = (5-3)/2
x = 2/2
x = 1
Check:
3^2(1)+3 = 243
3^2+3 = 243
3^5 = 243
3×3×3×3×3 = 243
9×9×3 = 243
81×3 = 243
243 = 243
To solve this you have to use cross multiplication.
This gives you 3(x-5)=2(x+2)
3x-15=2x+4
x-15=4
x=19
35+70 = 105
180-105 = 75
x = 75
Answer:
h(-5) = 34
Step-by-step explanation:
h(x) = -5x + 9
h(-5) = -5(-5) + 9 = 25 + 9 = 34
