Diana has 18 apples more than Roberto. Together, Diana and Roberto's apples are 48. How many apples does each have?​

Answers

Answer:

Diana has 33 and Roberto has 15.

Step-by-step explanation:

Use D for the amount of apples Diana has and R for Roberto

D=R+18

D+R=48

Use Substitution to solve the system of Equations

R+18+R=48 ----> 2R+18=48- Subtract 18

2R=30- DIvide by 2

R=15

Substitute R into another equation

D=R+18

D=15+18

D=33

[tex]y=\frac{1}{6}x+\frac{2}{3}[/tex]

Step-by-step explanation:

(8,2) (2,1)

First, you will need to find the gradient (or the m value in [tex]y=mx+b[/tex])

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

y2=1

y1=2

x2=2

x1=8

Now we can plug in these values to get the m value.

[tex]m=\frac{1-2}{2-8}[/tex]

Because the numerator and the denoinator will be negative, we needed to divide them to get a positive fraction.

[tex]m=\frac{-1}{-6} \\m=\frac{1}{6}[/tex]

Now we need to find the line of the equation using the following equation:

[tex]y-y1=m(x-x1)[/tex]

Now plug in the values using x1 and y1.

[tex]y-2=\frac{1}{6} (x-8)[/tex]

We can use the distributive property to distribute the [tex]\frac{1}{6}[/tex].

[tex]y-2=\frac{1}{6}x-\frac{4}{3}[/tex]

Lastly, we can add 2 to both sides to cancel out the -2 on the left to give us our equation.

[tex]y=\frac{1}{6}x+\frac{2}{3}[/tex]

X1 + X2 =-8
3X1 +2X2 = 18​

Answers

Answer:

X1 = 34

X2 = -42

Step-by-step explanation:

Given the simultaneous equations

X1 + X2 =-8 .... 1 * 3

3X1 +2X2 = 18​ .... 2 * 1

______________________

3X1 + 3X2 = -24

3X1 +2X2 = 18​

Subtract

3X2 - 2X2 =-24 - 18

X2 = -42

Substitute X2 = -42 into 1

X1 + X2 = -8

X1 - 42 = -8

X1 = -8+42

X1 = 34

Hence the solution to the system of equation is (34, -42)

A slope is also known as the gradient of a line. The slope of the line is -0.25. The correct option is B, -0.25.

What is Slope?

A slope is also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

The two points of the graph are given as (-3,3) and (1,2). Now, the slope of the line can be written as,

Slope = (3 - 2) / (-3 - 1)

          = 1/-4

          = -0.25

Hence, the slope of the line is -0.25.

Line M passes through the points (5,-4) and (9,10). When line n is plotted, it has no points in common with line m. Which of the following must be the slope of line n?

Answers

Answer:

Slope, m = 7/2 or 3.5

Step-by-step explanation:

Given the following data;

Points on the x-axis (x1, x2) = (5, 9)

Points on the y-axis (y1, y2) = (-4, 10)

To find the slope;

Mathematically, slope is given by the formula;

[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]

[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Substituting into the equation, we have;

[tex] Slope, m = \frac {10 - (-4)}{9 - 5} [/tex]

[tex] Slope, m = \frac {10 + 4}{4} [/tex]

[tex] Slope, m = \frac {14}{4} [/tex]

Slope, m = 7/2 or 3.5

b. Write an equation showing that Reggie answered all 35 questions on the

test.

Answers

Answer:

5x - 2y = 30

Step-by-step explanation:

Number of correct answers = x

Number of incorrect answers = y

Points won per correct answer = 5

Points lost per incorrect answer = 2

If Reggie received 30 points :

Required equation :

(points won per correct answer * number of correct answers) + (points lost per incorrect answer * number of incorrect answers)

5x + (-2y) = 30

5x - 2y = 30

Equation showing that Reggie answer all 35 questions :

Find the measures of HAB and CAB.

Answers

Answer: Angle HAB= 66 and Angle CAB= 44

Step-by-step explanation:

Since angle EAF=90 and FAD=20 then DAH must equal 70 degrees because it is 180 degree angle. Since DAH and EAC are vertical angles they are equal so EAC = DAH= 70 degrees. For the other side of 180 degrees then 70+5x=180

5x=110

x=22

CAB= 2(22)= 44 degrees

HAB= 3(22)=66 degrees
