Answer:

25

Step-by-step explanation:

30 goes into 750 25 times.

You can check your answer by multiplying 30 by 25 which equals 750. Therefore your answer is correct.

The 750 divided by 30 equals 25. This means that if we distribute 750 objects into 30 groups equally, each group would contain 25 objects.

When we divide 750 by 30, we can calculate the result as follows:

750 ÷ 30 = 25

Therefore, 750 divided by 30 equals 25. This means that if we distribute 750 objects into 30 groups equally, each group would contain 25 objects. Division is the arithmetic operation that allows us to determine how many times one number (the divisor) can be subtracted from another number (the dividend) without resulting in a negative value.

In this case, when we divide 750 by 30, we find that the quotient is 25. This represents the number of groups or units we can obtain when dividing 750 into 30 equal parts. Division is a fundamental mathematical operation used in various real-life scenarios, such as distributing resources, calculating averages, and solving ratio problems.

Graph is below.

Step-by-step explanation:

The solutions of the equations are : x = [8 ± √ 40] / 4

Given,

Y=2x² - 8x+3

Now,

To get the solution of equation equate it to 0 .

2x² - 8x+3  = 0

By quadratic formula,

x = -b ± √ b² - 4ac/2a

Substitute the values in the formula,

x = [8 ± √ 64 - 4(2)(3)] / 2* 2

x = [8 ± √ 40] / 4

Now plot the points in the graph. The graph is attached below.

Answer:

$23

Step-by-step explanation:

let j be jacob"s money

Then angie is 3j, and Erin is 3j+35 so 7I

=161

j=23

Answer: Erin - $104; Angie - $69; Jacob - $23.

(please give me brainlest ❤️)

Step-by-step explanation:

JACOB has least amount of money, so let's say that he has :

x amount of money

ANGIE has 3 times more than jacob:

Angie has 3x

ERIN has $35 more money than Angie:

3x+35

their money together is $196, that means if we add all of their money, it will be equivalent of 196:

3x+35+3x+x=196

now lets find x value.

put all the xes on right side and all known numbers on left side.

i think u know that when it goes to another side it changes sign; for example - makes + and × makes /

3x+35+3x+x=196

7x=161

x=161/7

x=23

now plug x values for each kid:

so Jacob had x=23

Angie had 3x=3×23=69

and Erin had 3x+35=69+35= 104

lets check our answer:

23+69+104=196

196=196

so sum of their money really gives us $196.

Let

x------> height of Leon's older brother

Convert mixed number to an improper fraction

4\frac{3}{4}\ ft=\frac{4*4+3}{4}= \frac{19}{4}\ ft443 ft=44∗4+3=419 ft

we know that

x=\frac{19}{4}\ ftx=419 ft -----> equation A

y=x-\frac{1}{3}y=x−31 -----> equation B

substitute equation A in equation B

y=\frac{19}{4}-\frac{1}{3}=\frac{53}{12}\ fty=419−31=1253 ft

Convert to mixed number

\frac{53}{12}=\frac{48}{12}+\frac{5}{12}=4\frac{5}{12}\ ft1253=1248+125=4125 ft

therefore

Answer:

[tex]y = \frac{-7}{3}x -12[/tex]

Step-by-step explanation:

Point-slope form is [tex]y-y_1= m (x-x_1)[/tex]. The [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] have to be substituted for with real values in order to make an equation of a line. From there, you can isolate [tex]y[/tex] to turn it into slope-intercept form.

1) First, let's find the slope of the line, which is represented by the variable [tex]m[/tex]. Use the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], to find the slope. [tex]x_1[/tex] and [tex]y_1[/tex] are the x and y values of one point, [tex]x_2[/tex] and [tex]y_2[/tex] are the x and y values of another point. For this problem, let's use the given points (-3, -5) and (-6, 2):

[tex]\frac{(2)-(-5)}{(-6)-(-3)} \\= \frac{2+5}{-6+3} \\= \frac{7}{-3}[/tex]

Thus, the slope is [tex]\frac{7}{-3}[/tex].

2) Now that we have the slope, let's substitute it into the point-slope formula. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point that the line intersects so you could either use (-3, -5) or (-6,2), but for this answer, I used (-6,2). (The answer will always be the same no matter which point you choose.) Substitute these values then isolate y to put it in slope-intercept form:

[tex]y-(2) = \frac{-7}{3} (x-(-6))\\y -2 = \frac{-7}{3} (x+6)\\y-2 = \frac{-7}{3}x-\frac{42}{3} \\y -2 = \frac{-7}{3}x-14\\y = \frac{-7}{3}x-12[/tex]

So, [tex]y = \frac{-7}{3}x -12[/tex] is the answer.

Step-by-step explanation:

because you do some math, open a calculator and boom, you have that.

Answer:

They got 14 books at $22 and 21 books at $34.

Step-by-step explanation:

From the information given, you can write the following expressions:

x+y=35 (1)

22x+34y=1022 (2), where:

x is the number of books that cost $22

y is the number of books that cost $34

First, you can solve for x in (1):

x=35-y (3)

Then, you can replace (3) in (2) and solve for y:

22(35-y)+34y=1022

770-22y+34y=1022

12y=1022-770

12y=252

y=252/12

y=21

Finally, you can replace the value of y in (3) to find x:

x=35-y

x=35-21

x=14

According to this, the answer is that they got 14 books at $22 and 21 books at $34.

Reduce the number with the greatest common factor 4:

[tex] - \frac{1}{9} \times \frac{3}{2} [/tex]

Reduce the number with the greatest common factor 3:

[tex] - \frac{1}{3} \times \frac{1}{2} [/tex]

Multiplying the fractions:

[tex]1 \times 1 = 1 \\ 3 \times 2 = 6[/tex]

Therefore, the answer will be - 1/6.
