11. If 1 is subtracted from the numerator and from
the denominator of a fraction, the value obtained
1
is z. If 1 is added to its numerator and to its
denominator, the resulting value is Ž. Find the
fraction.
Answer:
3/5
Step-by-step explanation:
Let x be the numerator
Let y be the denominator
1st equation:
(x-1) / (y-1) = 1/2
By simplifying the equation, 2(x-1) = y-1
y = 2(x-1) + 1
2nd equation:
(x+1) / (y+1) = 2/3
By simplifying the equation, 3(x+1) = 2(y+1)
3x + 3 = 2y + 2
2y = 3x + 1
y = (3x + 1) / 2
Substituting the value of y from the 1st equation to the 2nd equation:
1st equation: y = 2(x-1) + 1
2nd equation: y = (3x + 1) / 2
2(x-1) + 1 = (3x+1) / 2
x = 3
After finding the value of x, let's find y using the 2nd equation:
y = (3x + 1) / 2
y = [(3)(3) + 1] / 2
y = 5
Alternatively, we may also find the value of x using the first equation, and the result is still the same:
y = 2(x-1) + 1
y = 2(3-1) + 1
y = 5
CHECKING TIME!!!
Substituting the values of x and y:
Let x be the numerator, x = 3
Let y be the denominator, y = 5
1st equation: (x-1) / (y-1) = 1/2
(3-1) / (5-1) = 1/2
2/4 = 1/2
By simplification, 1/2 = 1/2
2nd equation:
(x+1) / (y+1) = 2/3
(3+1) / (5+1) = 2/3
4/6 = 2/3
By simplification, 2/3 = 2/3

Answer:
h(-4) = -1
h(-1) = -1
h(0) = 2
Step-by-step explanation:
h(-4) = -1 because -4<-1 and from the instructions if x < -1, it is -1
h(-1) = -1 because -1 = -1
h(0) = 2 because if 1<x<2 than we have to solute this -(x-1)^2 + 3
in this we have to replace x with 0
-(0-1)^2 + 3= -(-1)^2 + 3 = -1 +3 = 2

Maia was baking cupcakes for a party. She mixed 4 drops of red food coloring for every 6 drops of yellow food coloring to dye her icing orange. Circle the ratios of food coloring drops that would create the same orange color and justify your choices
Choice 1: 2 red to 3 yellow
Choice 2: 24 red to 26 yellow
Choice 3: 40 yellow to 100 red
To make the same orange circle, you would need 2:3 drops of food coloring.
A ratio is defined as:A ratio is a mathematical statement that compares and equals two variables.
Fractions, percentages, and decimals are used to represent ratios.
According to this ratio (2:3), Maia uses 60% of yellow food coloring to create an orange circle for every 40% of red food coloring.
Information and calculations: 4 red food coloring drops
Yellow food coloring drops equal six.
Food coloring ratio = 4:6 or 2:3.
The ratios are as follows in percentages:
Red food coloring drops equal 40% (2/5 x 100)
60 (3/5 x 100) drops of yellow food coloring
As a result, the food coloring is divided into 40% red and 60% yellow.

Krishnan had $10.he bought box of crayons and a pen. A box of crayons cost twice as much as a pen. He received $4 change.how much did the pen cost?
The cost of the Crayons will be $4 and the cost of the Pen will be $2.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Krishnan had $10. He had to purchase a box of pastels and a pen. A case of pastels costs two times as much as a pen. He got a $4 change.
Let c be the cost of crayons and p be the cost of a pen. Then the equations are given as,
c = 2p ...1
c + p = 10 - 4 ...2
From equations 1 and 2, then we have
2p + p = 10 - 4
3p = 6
p = 2
Then the cost of the crayons will be given as,
c = 2 x 2
c = 4
The cost of the Crayons will be $4 and the cost of the Pen will be $2.

Answer:
7
Step-by-step explanation:
5(5)-3x7+3 Due to parenthesis you need to multiply 5 to 13-8 (which is 5) first.
25-3x7+3 Now you need to multiply 3 and 7 before anything else
25-21+3 now since its just subtraction and addition you go from left to right
4+3
7
Answer:
7
Step-by-step explanation:
Using order of operations to solve the expression:
Step 1: any terms in parenthesis
(13-8)=5
The expression becomes 5(5)-3*7+3
Step 2: any exponents
There are no exponents so the expression doesn't change.
Step 3: multiplication or division
5(5)=25
3*7=21
The expression becomes 25-21+3
Step 4: addition or subtraction
25-21+3=7

Answer: [tex]7\sqrt{2[/tex]
Step-by-step explanation:
a²+b²=c²
7²+7²=c²
49+49=c²
[tex]\sqrt{98}=\sqrt{c^2}\\\sqrt {49}\sqrt{2} =c\\ 7\sqrt{2} =c[/tex]
Answer:
7[tex]\sqrt{2}[/tex]
Step-by-step explanation:
To find the missing length of a right triangle use the Pythagorean theorem. This theorem is [tex]a^2+b^2=c^2[/tex]. The variables a and b are the legs (shorter sides) and c is the hypotenuse (longest side). In this case, the hypotenuse is the missing side. So, add and square 7. This looks like [tex]7^2+7^2=x^2[/tex]. So, [tex]98=x^2[/tex]. Finally, square root 98 to get the final answer, [tex]\sqrt{98}[/tex]. This can be simplified to [tex]7\sqrt{2}[/tex].
Additionally, this is a special right triangle because the legs are of equal length. If the legs are equal then the hypotenuse with be equal to x[tex]\sqrt{2}[/tex], where x is the length of the legs. So this problem can also be solved using this method.
