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

How many days is 1,000 hours?
Answer:
41.6666667 or 41 2/3 days
Step-by-step explanation:
There are 24 hours in a day. So you need to divide the hours by 24.
1000/24 is 41 and 2/3 days
Answer:
41.666667
Explanation:
Divide by 24 because 1 day is 24 hours
1000 / 24 = 41.666667

Answer:
[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]

the sum of 2 fractions 8/9. the difference 2/9. what are the 2 fractions?
Answer:
5/9 and 3/9
Step-by-step explanation:
run through the different possibilities and see what has a difference of 2/9th. Here is the way I ran through it
1/9 + 8/9 Difference is not 2/9th
2/9 + 6/9 Difference is not 2/9th
3/9 + 5/9 Difference is 2/9th. This is our answer
Step-by-step explanation:
5/9 and 3/9.....add 5/9 and 3/9 and you will get 8/9....if you subtract 5 and 3 it will give you 2....5/9-3/9=2/9

Which of the following is known as a simpler form of Euclid's fifth postulate
and led to the discovery of non-Euclidean geometry?
A. Playfair's axiom
B. Poincaré disk
C. Riemann's negation
D. Zeno's paradox
Answer:
A. Playfair's axiom.
Step-by-step explanation:
In a plane, given a line and a point not on it, at most, one line parallel to the given line can be drawn through the point.
- this implies Euclid's fifth postulate.
X1 + X2 =-8
3X1 +2X2 = 18
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?
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
Romell receives five points for each correct answer on a
test and loses two point for each incorrect
answer.
a. Write an equation showing that Reggie received 30 points.
6x = 30
b. Write an equation showing that Reggie answered all 35 questions on the
test.
Answer:
5x - 2y = 30
x + y = 35
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 :
Number of correct answers + number of incorrect answers = 35
x + y = 35

Find the measures of HAB and CAB.
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
