Solve the simultaneous equations 2x + y = 5 and 2y = x – 10.
Answers
The first equation can be substituted into the second one. It would be: 2(-2x+5)=x-10 and after solving it, x = 4

The given equations are :
[tex]2x + y = 5[/tex][tex]2y = x - 10[/tex]From the first equation, we get :
[tex]2x + y = 5[/tex][tex]y = 5 - 2x[/tex]now, let's put the value of y as (5 - 2x) in second equation to find the value of x :
[tex]2y = x - 10[/tex][tex]2(5 - 2x) = x - 10[/tex][tex]10 - 4x = x - 10[/tex][tex]5x = 20[/tex][tex]x = 4[/tex]hence, value of x = 4, Plugging the value of x in second equation :
[tex]2y = x - 10[/tex][tex]2y = 4 - 10[/tex][tex]2y = - 6[/tex][tex]y = - 3[/tex]so, the required values are :
x = 4 y = -3421 divide by 27 with remadire help
Answers
Answer:
Therefore, the answer to 421 divided by 27 calculated using Long Division is:
15
16 Remainder
Step-by-step explanation:
421 = dividend
27 = divisor
Step 1:
Start by setting it up with the divisor 27 on the left side and the dividend 421 on the right side like this:
2 7 ⟌ 4 2 1
Step 2:
The divisor (27) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:
0
2 7 ⟌ 4 2 1
Step 3:
Multiply the divisor by the result in the previous step (27 x 0 = 0) and write that answer below the dividend.
0
2 7 ⟌ 4 2 1
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.
0
2 7 ⟌ 4 2 1
- 0
4
Step 5:
Move down the 2nd digit of the dividend (2) like this:
0
2 7 ⟌ 4 2 1
- 0
4 2
Step 6:
The divisor (27) goes into the bottom number (42), 1 time(s). Therefore, put 1 on top:
0 1
2 7 ⟌ 4 2 1
- 0
4 2
Step 7:
Multiply the divisor by the result in the previous step (27 x 1 = 27) and write that answer at the bottom:
0 1
2 7 ⟌ 4 2 1
- 0
4 2
2 7
Step 8:
Subtract the result in the previous step from the number written above it. (42 - 27 = 15) and write the answer at the bottom.
0 1
2 7 ⟌ 4 2 1
- 0
4 2
- 2 7
1 5
Step 9:
Move down the last digit of the dividend (1) like this:
0 1
2 7 ⟌ 4 2 1
- 0
4 2
- 2 7
1 5 1
Step 10:
The divisor (27) goes into the bottom number (151), 5 time(s). Therefore put 5 on top:
0 1 5
2 7 ⟌ 4 2 1
- 0
4 2
- 2 7
1 5 1
Step 11:
Multiply the divisor by the result in the previous step (27 x 5 = 135) and write the answer at the bottom:
0 1 5
2 7 ⟌ 4 2 1
- 0
4 2
- 2 7
1 5 1
1 3 5
Step 12:
Subtract the result in the previous step from the number written above it. (151 - 135 = 16) and write the answer at the bottom.
0 1 5
2 7 ⟌ 4 2 1
- 0
4 2
- 2 7
1 5 1
- 1 3 5
1 6
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 421 divided by 27 calculated using Long Division is:
15
16 Remainder

Find the x- and y-intercepts of : 4y-6x = 24
Answers
Answer:
x-intercept: (-4, 0)
y-intercept: (0, 6)
Step-by-step explanation:
4y - 6x = 24
To find the x-intercept, set the y value equal to 0.
4(0) - 6x = 24
Simplify by removing 4(0) since it just equals 0.
-6x = 24
Divide both sides of the equation by -6
x = -4
Since we set y equal to 0 and we know that the x value is -4, we can create a coordinate for the x-intercept of the equation.
(x, y) = (-4, 0)
Repeat the process for finding the y-intercept, but set x equal to 0.
4y - 6(0) = 24
4y - 0 = 24
4y = 24
Divide both sides of the equation by 4
y = 6
Write as a coordinate/intercept.
(x, y) = (0, 6)

Jake earns $8 per hour for cutting grass. If he works a 35-hour week,
how much money will he earn?
Answers
There are many ways to solve these types of questions. But I am going to use the fraction method.
Step 1: Set up a fraction.
Setting up a fraction, given the question will be the units on the same level. And the money earned will be a variable, "[tex]m[/tex]". It does not matter whether they are top or bottom.
[tex]\frac{8}{1} = \frac{m}{35}[/tex]
Step 2: Solve
[tex]\frac{8}{1} = \frac{m}{35}[/tex]
Multiply 35 to both sides[tex]\frac{35m}{35}=8\cdot \:35[/tex]
[tex]m=280[/tex]
Therefore, Jake will earn $280.

Answer:
a) x=56º
b= Angle x is on a line. All lines create linear angles, so together all angles that are on that side of the line = 180º. Since the two lines were parallel we know that the two angle measurements next to x are congruent. So 180=62+62+x.

D. SAT scores compared to hours spent studying
Answers
Answer: B
Step-by-step explanation: The tomato grows more over time so it will be a positive..
The height of a tomato plant throughout the year shows a positive linear correlation coefficient option (B) is correct.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
A. grade point average compared to the number of hours a student watches TV.
The grade points depend on the number of hours a student watches TV.
If watching time increases the grade point decreases.
B. the height of a tomato plant throughout the year
The height of a tomato and the number of years show a positive linear correlation.
C. a person's salary compared to the amount of education they have attempted:
The above situation represents an exponential regression.
D. SAT scores compared to hours spent studying
If the time spent in studying increases the SAT scores increases rapidly.
Thus, the height of a tomato plant throughout the year shows a positive linear correlation coefficient option (B) is correct.

Answers
Answer:
x = 9
y = 6
Step-by-step explanation:
Let's set up equations:
x + y = 15
x - y = 3
Let's rearrange one of these equations to use the substitution method:
x - y = 3
Add y to each side:
x = y + 3
Substitute in for x:
x + y = 15
y + 3 + y = 15
Combine like terms:
( y + y ) + 3 = 15
2y + 3 = 15
Subtract 3 from each side:
2y = 12
Divide each side by 2:
y = 6
Substitute this in to find the other variable:
x + y = 15
x + 6 = 15
Subtract 6 from each side:
x = 9
