Karina is baking bread. She buys a small bag of flour that contains 2[tex]\frac{2}{3}[/tex]cups of flour. The recipe calls for 2 [tex]\frac{5}{7}[/tex]cups of flour. Does she have enough flour to bake the bread? Explain how she can compare the fractions to know for sure.
Answer:
to compare she must calculate...
1) ((2*3)+2)/3 she get 2.666
2) ((2*7)+5)/7 she get 2.714
by approximation the two are the same and she had enough flour.
Using approximation, the two are the same and she has enough flour.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that Karina buys a small bag of flour that contains [tex]2\frac{2}{3}[/tex] cups of flour. The recipe calls for [tex]2\frac{5}{7}[/tex] cups of flour.
1) [tex]2\frac{2}{3}[/tex] cups of flour.
= ((2 x 3)+2)/3
= 2.666
Hence, she get 2.666
2) [tex]2\frac{5}{7}[/tex] cups of flour.
= ((2x 7)+5)/7
= 2.714
Hence, she get 2.714
Using approximation, the two are the same and she has enough flour.

Conversion a mixed number 2 2/5 to a improper fraction:-
=> 2 2/5 = 2 × 5 + 2 = 12/5
To find new numerator:
a) Multiply the whole number 2 by the denominator 5. Whole number 2 equally 2 * 5/5
= 10/5
b) Add the answer from previous step 10 to the numerator 2. New numerator is 10 + 2 = 12
c) Write a previous answer (new numerator 12) over the denominator 5.
Two and two fifths is twelve fifth
Multiple:
= 12/5 × 5/7
= 12 × 5/5 × 7
= 60/35
= 12 × 5/7 × 5
= 12/7
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(60, 35) = 5. In the next intermediate step, , cancel by a common factor of 5 gives 12/7
12/7 in mixed fraction is 1 5/7

Which statement about the solving process when an equation has no solution or infinite solutions is TRUE?
The variable will always end up on the left-hand side of the equation.
The constant terms will always be a multiple of 3.
Collecting the like terms will result in the elimination of the variable.
Gathering the like constant terms will always result in the value 0.
Answer:
A
Step-by-step explanation:
The variable will always end up on the left-hand side of the equation
The statement that is true about the solving process when an equation has no solution or infinite solutions is: “The variable will always end up on the left-hand side of the equation.” Hence, Option A is correct.
What are infinite solutions?Both sides are equivalent in an endless solution. For instance, 12x + 4y - 16 = 6x + 2y - 8 Using a formula or method for infinite solutions, one can simplify the equation and make both sides equal to one another, making it an infinite solution. Infinity is a symbol for boundlessness or infinity. The sign "∞" is typically used to denote it.
When the lines are parallel and they share the same y-intercept, the system of equations has an infinite number of solutions. If the slope and y-intercept of two lines match, they are in fact the exact same line. The variable, which always appears on the left side of the equation, has infinite solutions.
Therefore, Option A is correct.

A (I cant say it on here for some reason )water fish tank requires a certain salinity. To reach this requirement, the relationship between gallons of water and pounds of salt needs to be proportional. The relationship can be modeled as a line on the coordinate plane where x represents the number of gallons of water and y represents the number of pounds of salt. If the line passes through the point (5,1.5) , what does that point represent?
Answer: Represents when the equation is at 5 gallons of water 1.5 pounds of salt is needed to have the correct salinity

Step-by-step explanation:
For all of these, we can use indecy laws such as when there is a power of a power, you can multiply the powers.
Using this, we get 6^-3 x -1 or,
6^3
For the second one we get (6)^-3 x 3 or,
6^ of negative 9 which is neither.
I am guessing that the last 2 are fractions. (1/6)^-3 is equal to 216 which is 6^3.
For the last one, (1/6)^3 is basically the opposite so the answer is 6^-3.

18*42= 756
make an equation with data you have;
If 189 cost $1.31
756 cost $x
____________
756 *1.31 / 189 = $5.24 cost for second fabric
Second way;
(18x42) / (21x9) = 4 x 1.31 = $5.24

A car traveled on 3 gallons of gas = 63 miles
car traveled on 1 gallons of gas = = 21 miles
Therefore, car traveled on 7 gallons of gas = 21 × 7 = 147 miles.
The proportion will be = × 7 = × 7
