Step-by-step explanation:
1/20-1/4 ×<1/5-2/5×
<h3>collection of like terms</h3>
1/20+1/5 <-2/5×-1/4×
<h3>= 1/4 <-13/20×</h3>
8 because AB=BC as they are isosceles and 5/2.5=2 therefore ACx2=JL= 8
Answer:
x=9
Step-by-step explanation:
logx (531441) = 6
Changing this to an exponential
x^6 =531441
Take the 6th root of each side
(x^6)^1/6 = (531441)^1/6
x =9
Answer/Step-by-step explanation:
What we already know:
Pizza slices $2.75 - Ice cream cones $2.25 - Tacos $1.75
Total Items sold - 121 / Total amount of money - $260.75/ <u>$87.50 made from selling Tacos</u>
<u>____________________________________</u>
Tacos - 87.5 ÷ 1.75 = 50 Tacos sold -- 121 - 50 = 71 items
& 260.75 - 87.5 = 173.25 left
____________________________________
You can't sell half an Ice-Cream
Ice Cream - 71 - 1 = 70 -- 70 ÷ 2 = 35 -- 35 × 2.25 =
<h3>
$78.75 made from Ice-cream cones</h3><h3>
35 Ice- cream cones sold</h3><h3>
**************************************************</h3>
Pizza slices - 71 - 70 = 1 -- 1 + 35 =
<u>36 Pizza slices sold</u>
36 × 2.75 =
<u>99 dollars made off of Pizza slices</u>
