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

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

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.

The amount of flour that the bakery used this month was a 40% increase relative to last month.
Six friends order lunch. Which expression shows the total cost if each person orders one sandwich and one cookie?
Answer:
6(4.75+x)
Step-by-step explanation:
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.
