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)
(URGENT) Worth all my points 7.3
Answer:
Step-by-step explanation:
I'll assume that all the angles are 90°, and there is no bottom to the box.
To determine the wood needed, calculate the surface area of the bed. Since there is no bottom or top to the box, the amount of wood is 2(45 in × 21 in) + 2(22 in × 21 in) = 1890 in² + 924 in² = 2814 in²
To determine the soil needed, calculate the volume of the box.
volume = 45 in × 21 in × 22 in = 20,790 in³

You invest $400 at 7 % annual interest, compounded continuously. When will the account be worth $600?
Answer:
8 years
Step-by-step explanation:
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
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

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

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

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

What is the population in 2020 of a place that has a population of 4 million people in 2011 and is growing at a rate of 1.3%?
Answer:
370 million
Step-by-step explanation:
In the 10 years from 2000 to 2010, the population was multiplied by the factor ...
100% + 9.6% = 109.6% = 1.096
In the next 20 years from 2010 to 2030, the population will be multiplied by that factor twice, if it grows at the same rate:
2030 population = (308 million)·(1.096²) ≈ 370 million
