Step-by-step explanation:

Answer:

4

Step-by-step explanation:

I don't really know how to show the steps, but one of the easiest ways to do this is to see how many times 0.8 goes into 3.2.  So 0.8 + 0.8 + 0.8 +0.8 = 3.2  So 3.2/0.8 is 4

Or you can multiply the numerator and denominator by 10, which keeps the value of the fraction but gets rid of pesky decimals: 32/8 this should be fairly straight forward and a key reason to memorize your times tables.  8*4=32

Step-by-step explanation:

Substituting y = 3x - 4 into the equation gives

7x - 5(3x - 4) = 4 ← distribute and simplify left side

7x - 15x + 20 = 4

- 8x + 20 = 4 ( subtract 20 from both sides )

- 8x = - 16 ( divide both sides by - 8 )

x = 2

Substitute x = 2 into y = 3x - 4

y = 3(2) - 4 = 6 - 4 = 2

Answer:

vertex = (3, 2 )

Step-by-step explanation:

The vertex is the turning point of the graph.

This occurs at (3, 2 ) ← vertex

Answer:

The vertex is at (3, 2)

Step-by-step explanation:

Hello!

The vertex of a parabola is the point of turning, or the minimum/maximum point of the parabola.

Since the graph opens up, the vertex is at the minimum point.

The y-value is 2, and the x-value is 3, giving us the vertex of (3, 2)

There are other parts to parabola than just the vertex.

The number of teams formed by the total number of students will be 4.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that centre, Middle School is having a pie eating contest and needs a team consisting of 5 people from Mrs Brown's classroom. There are 20 students in Mrs Brown's classroom.

The number of teams will be calculated as,

N = 20 / 5

Answer:

1/4 parts of cement

Step-by-step explanation:

Given :

3 parts of cement = 12 parts of sand

For each part of sand, let the part of cement used = x

Writing the relation in the form of cross multiplication :

3 = 12

x = 1

Cross multiply :

12x = 3

x = 3 / 12

x = 1/4

Hence, for each part of sand, 1/4 parts of cement is used.

Explanation:

There are 5 gold and 350 total. That forms the fraction 5/350 which fully reduces to 1/70 after you divide both parts by the GCF = 5

A = 5, B = 350

The fraction 1/70 can be thought of like saying "There's 1 gold coins in 70 coins total" or "there's 1 gold coin for every 70 coins".

Then we could scale up like so

Look at the picture for the answer :D

Step-by-step explanation:

The x coordinate comes first, then the y.

Answer:

(7, 5)

Step-by-step explanation:

(5,12)

x : 5 + 2 = 7

y : 12 - 7 = 5

(7,5)

The value of (x, y) --> (7, 5).

An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. The numeric values in an ordered pair can be integers or fractions.

Given point is (5,12)

We have to solve for

(x,y) --> (x + 2, y - 7)

Now put x=5 in x+2

x = 5 + 2

= 7

and, y= 12 in y-7

y = 12 - 7

= 5

Hence, (x, y) --> (7, 5).

Answer:

150-1/2 (150.5) cups of flour

Step-by-step explanation:

We know there is a ratio of 32.25 / 1.5 (32-1/4 cups of flour for every 1 1/2 batches of pie that she makes). X is the unknown (as we are trying to solve for flour) so we can set up the problem as such:

32.25    =     x  

1.5                 7

Now we cross multiply to solve:

1.5(x) = 7(32.25)

1.5x = 225.75  -- Simplify then divide both sides by x (to isolate the variable)

x = 150.5

Answer: She uses 32 ¼ cups of flour for every 1 ½ batches of pie

Let’s make it into whole numbers to start…

She uses 64 ½ cups of flour for every 3 batches of pie

She uses 129 cups of flour for every 6 batches of pie

She uses 129/6 cups of flour for every 1 batch of pie

She uses 7 x 129/6 cups of flour for every 7 batches of pie

= 150 ½ cups of flour
