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

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

A farmer's land is separated into sections of size 3 3/4 acres. Suppose there are 2 1/5 such sections. How many acres of land does the farmer own?
Write your answer as a mixed number in simplest form.
Answer:
This is simple multiplication of fractions, not too bad!
we have 2 7/9 sections of farmland, each 2 1/5 acres large. To find the total acreage, multiply 2 1/5 by 2 7/9. The first step here is to convert to improper fractions.
To convert to improper fractions, multiply the denominator of the mixed number by the "whole number" portion of it. Then, add the numerator of the mixed number. For example, for 2 1/5, I would multiply 5 * 2 to get 10, then add 1 to get 11. Then, I keep the original denominator, so 11/5.
Let's do the same for 2 7/9. 9 * 2 = 18, then add 7 to get 25. The improper fraction is 25/9.
Now, we multiply the two fractions. This is just multiplying both numerators and both denominators, straight across.
(11*25)/(9*5) = 275/45 => 55/9, so that's the total acreage, or in decimal form, about 6.11 acres.

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.

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.
simplify the expression by arranging the steps in sequence, based on the order of operations.

How is solving a two-step equation similar to solving a one-step equation?
Answer:
Because it is the same concept, now u have to do more work.
For example
1+1 would be a one step equation
and
1+1(5) would be a two step equation
it's just a bit more.
Each step in solving an equation is like solving a one-step equation so solving a two-step equation is similar to solving a one-step equation
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 9 is an equation
We have,
Two steps equation.
Example:
2 + 3 - (3 x 4)
Step 1:
2 + 3 - 12
Step 2:
5 - 12
-7
One-step equation.
Example:
2 + 4
Step 1:
2 + 4
6
We see that,
Solving a two-step equation is similar to solving a one-step equation because, in the two-step equation, each of the two steps is like one step individually.
Thus,
Solving a two-step equation is similar to solving a one-step equation.

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.

What is the equation of the graph obtained by reflecting y=3^x In the x axis
Answer:
y=-3x
Step-by-step explanation:
Shows the original equation reflected arcoss x axis
The equation of the graph obtained by reflecting y = 3ˣ in the x-axis is y = -3ˣ .
To reflect a function in the x-axis, we change the sign of the y-values of each point on the graph. In this case, we are reflecting the function y = 3ˣ .
When we reflect y = 3ˣ in the x-axis, the equation becomes y = -3ˣ. The negative sign in front of the 3ˣ term indicates the reflection in the x-axis .
Therefore, the equation of the graph obtained by reflecting y = 3ˣ in the x-axis is y = -3ˣ .
