Answer:
X = -12.54 (I am a Math Class Topper in both 6th Grade an 7th Grade)
Step-by-step explanation:
5 x .27 = 1.35
8x - (3 x .27) = .81
1.35 + 8x - .81 = 7x - 12
- 7x - 7x
----------------------------------
1.35 + X - .81 = -12
+ .81 +.81
---------------------------
1.35 + X = -11.19
-1.35 -1.35
-----------------------
X = -12.54
Your answer is $1.26
You can solve this problem with or without a calculator, and I don't know if you're allowed one or not so I'll show you both ways
Calculator:
The easiest way to find percentages of values on the calculator is to use the decimal multipliers, which are just the decimal value of the percentage. For example, 50% would be 0.5, 75% would be 0.75 etc. The decimal value of 15% is 0.15, so you would do 8.40 × 0.15 = 1.26
Non-Calculator:
This is a bit longer, but gives you the same answer. To solve without a calculator, you first divide 8.40 by 10 to find 10%, which is 0.84. Now you can divide that by 2 to find 5%, which would be 0.42, and then you add the two values (because 10% + 5% = 15%) to get 1.26
I hope this helps!
Answer: 48 oz is the best buy
Step-by-step explanation:
You can get way more for cheaper considering 24oz costs $19.12 and if you do 24x2 you get 48 so if you buy 2 of the 24oz ones you have to pay $18.24
HOPE THIS HELPS ^^
Answer:
PQ=36
Step-by-step explanation:
o=114
PQ I named a because it was easier for me and SP I named b.
o=2(a+b)
114=2(3x+3+2x-1)
114=6x+6+4x-2
114=10x+4
10x=114-4
10x=110/:10
x=11
a=3*11+3
a=33+3
a=36
Answer:
it's (6,0) I can't explain though
