Answer:

30 kids

Step-by-step explanation:

21/30 = .7

.7 is 70% so if there are 30 kids then 70% of that would be 21.

Answer:

Option A. (4,0) and (-1,0)

Step-by-step explanation:

we know that

The equation of a vertical parabola in factored form is equal to

where

a is a coefficient

x_1 and x_2 are the zeros or x-intercepts of the function

In this problem we have

we have

The leading coefficient is negative, that means the parabola open downward

The zeros of the function are

Remember that the x-intercepts are the values of x when the value of the function is equal to zero

therefore

The x-intercepts are (4,0) and (-1,0)

Answer: 0.8925 x

Step-by-step explanation:

First, he gets it on sale, so (x-0.15x = 0.85 x)Then, take that 0.85x and multiply it by 1.05 (to add the sales tax). So the result is (0.85 x)(1.05) = 0.8925 x

Answer:The 5 - 3 goes to the first box and then 3 - x goes to the other

Step-by-step explanation:

Determine the total or difference is  - 2 . 3 . Equations of degree 1 are linear equations. It is the straight line's equation. A linear equation with parameters a and b equal to zero has the conventional form ax+by+c = 0.

Equations of degree 1 are linear equations. It is the straight line's equation. A linear equation with parameters a and b equal to zero has the conventional form ax+by+c = 0.

When two linear expressions are equal, there is a linear equation in one variable (or one is equal to a constant). Or, to put it another way, one method of resolving this problem is to graph the equation y = 2x+4 and locate the point at which its line intersects the line y = 10.

Given ,

3x-2(2.3x+2.5)=-1.6 x- 5 ,

5 - 3(- 1.6x -2.1) =4.8x-1.3 =4.8 x  -  1.3

Rearrange the equation's unknown terms to the left side:[tex]3x-2(2.3x+2.5)=-1.6 x- 5[/tex]

Law of Multiplicative Distribution: [tex]7x-2.6x+1.6x=-5+3[/tex]

Two opposites added together equal zero:[tex]7x-2.6x+1.6x=-5+3[/tex]

combining similar terms:0=0

Use the law of multiplicative distribution:[tex]5 - 3(- 1.6x -2.1) =4.8x-1.3 =4.8 x - 1.3[/tex]

Unknown terms should be moved to the left side of the equation:[tex]1.6x -4.8x= -1.3 -2.1 =4.8x-1.3 -5-3[/tex]

Two opposites added together equal zero:[tex]-1.6 x + 4 .8x =1.3 -5+4.4- 3[/tex]

Therefore Determine the total or difference:0= - 2. 3

Answer:

Callie multiplied incorrectly

Step-by-step explanation:

Here we have 0.42 × 4.73 = 1.9866 then

1.9866 + 29.4 + 168 = 199.3866

we had 0.42 × 4.73 = 1.26 which is incorrect meaning that Callie multiplied incorrectly

Callie multiplied as follows

0.42 × 3 = 1.26 but what was in the question was

0.42 × 4.73 which is equal to 1.9866.

Answer:

y = [tex]\frac{1}{2}[/tex]x + 3

Step-by-step explanation:

This question is simply asking you to find the slope in y=mx+b form.

Slope is rise over run. Because for each time the graph goes up one, it goes two to the left, the slope is [tex]\frac{1}{2}[/tex]. Therefore, your (mx) is [tex]\frac{1}{2}[/tex]x.

Your y-intercept, or b, is where the line intersects the y, or vertical, axis. Therefore, it would be 3.

Answer:

Step-by-step explanation:

First, change 35% to a decimal (0.35). Then do, 20 x 0.35 = 7. Lastly do, 20 - 7 = $13

or

You can First change 35% to a decimal (0.35). Then do, 1.00 - 0.35 = 0.65.

When your multiplying by 10 your just adding a zero onto the end of your current number, so when dividing you taking that away

Answer:

The numbers are 10, 12, and 14

Step-by-step explanation:

x + 2(x+2) = x+4 + 20

x = 10

So the numbers are 10,12,14

Here is your answer

let the numbers be x,x+2,x+4

so,the equation is

x+2(x+2)=x+4+20

3x+4=x+24

2x=20

x=10

therefore the nos. are 10,12,14

y = 3(3)

y = 9

3, 9

Hello there! :)

Instead of x, we plug in some value of x (the values are given)

y=3x

y=3(0)

Answer:

7: $34.25; 8: $20.75 each

Step-by-step explanation:

Question 7: The pattern is that each price is getting higher by $5.15 per hour, so multiply 5.15 by 2 to get the amount it'd be higher by 2 hours. The answer would be 10.30. Add $23.95 and $10.30 and you get $34.25 as your final answer

Question 8: The pattern in this question is that each price is getting lowered by $2.75 as more dogs get added. So, since it only shows the price per dog for 4 dogs, you have to multiply $2.75 by 4, and you get $11. Since thats the amount of money she's removing as she walks 4 more dogs, you subtract $11 from $31.75 ($31.75 - $11)  and get your answer of $20.75.

Hope this helps!
