Generic sugar which costs $2.23/kg is made by combining brand X sugar which costs $1.18/kg with brand Y sugar which costs $3.98/kg. Find the number of kg of brand X sugar and brand Y sugar required to make 40 kg of generic sugar.
Answer:
X = 14 kg
Y= 7 kg
Step-by-step explanation:
LET X and Y equal the amounts of brand X and Y
X = kg of brand X
Y = kg of brand Y
we know:
1) X + Y = 21 (kg)
2) 1X + 4Y = 2(X + Y) (This is the cost/kg * amounts for total cost)
Coefficients 1,4,2 are the cost/kg)
substitute eq. 1 (X+Y), = 21 into right side of equation 2
1X + 4Y = (21)*2
use elimination to solve 2 equations
X + Y = 21
X + 4Y = 42 (now subtract, note: I wrote the 1X as just X)
------------------
0 -3Y = -21 OR Y = 7 kg so X = (21-7) OR X = 14 kg

Can someone please help me with ALL 5 QUESTIONS? You will receive brainliest if you do so. Please help me I beg. I will fail my math class if I don't get a good grade on this assignment.
Evaluate a + b if a = 0 and b = -20
The answer is -20.
The number 0 has no value to it. So we would be adding nothing.0+-20=-20Even if we did add 0+20 the value would still be -20
Now if we added 1+-20 would be -19. We would need exactly 20+-20 to get out of the negitives.
Hope this helps ya!

Answer:
X=12
Step-by-step explanation:
I USED THE AREA TO FIND THE VALUE OF X.
I THOUGHT ABOUT THE 2 NUMBERS THAT GIVES US 48.
ONE OF THEM WAS (8 X 6)
AND BECAUSE THE UPPER X IS DEVIDED INTO 5 +N +N, THE 5 SHALL BE 8 SO N = 3 AND IN THE VERTICAL X , WE HAVE 2N AND A BLANK AND THE WHOLE GRAPH IS A SQUARE SO THE UPPER 8+N IS ALSO THE SIDE 6+2N
AND THE VALUE OF N = 3
SO X = 12

The sanctuary’s gift shop purchases items for the amounts shown in the table. Leo marks up the cost of each item by 45% to determine the gift shop’s selling price. How much would a customer pay for one pair of binoculars and one bird guide after the markup and 8.5% sales tax? Explain.
Answer:
382. 5
Step-by-step explanation:
Answer:
26.74 ($) or change currency sign to suit.
Step-by-step explanation:
Binoculars Mark up = 10x 1.45 = 14.50
Sales tax = 14.5 x 1.085 = 15.7325
Total cost per Binocular = 15.73 ($,)
Bird Guide Mark up = 7 x 1.45 = 10.15
Sales Tax = 10.15 x 1.085 = 11.01275
Total cost per Bird Guide = 11.01 ($)
One of each is found by addition.
15.73 + 11.01 = 26.74 ($) or change currency sign to suit.

Which explanation best completes the proof that QRST is square? Will give Brainlest
Answer:
It's the top one. No further explanation is needed.
Step-by-step explanation:
We know that a square is made-up of four equivalent sides, and four right angles. So, by process of elimination, you are left with the top one.
Another way of getting the same answer is we know that the only quadrealateral with four equivalent sides is a square, so the top answer is correct.
There you have two, different explainations and ways of getting the same answer, proving that it is correct. Hope that helps!
