Answer: x=10
Step-by-step explanation:
8x+2=72+x
1. Move like terms
8x-x=72-2
2.Collect like terms and calculate
7x=70
3. divide both sides
what is the answer to 6a + 6c =126
Answer:
Step-by-step explanation:
You can solve 6a + 6c =126 for either a or c, but until you have a second equation in either a or c or both, you cannot find the values of a and c.
6a + 6c =126 reduces to 6(a + c = 23), or just a + c = 23. Then either a = 23 - c or c = 23 - a, but we cannot find a or c as a specific numeric value.
Find the slope of the line passing through the points (3, 4) and (8, -3).
Answer:
[tex]\bold{m=-1\dfrac25}[/tex]Step-by-step explanation:
The slope of the line passing through two given points: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
(3, 4) ⇒ x₁ = 3, y₁ = 4
(8, -3) ⇒ x₂ = 8, y₂ = -3
So, the slope:
[tex]m=\dfrac{-3-4}{8-3}=\dfrac{-7}{5}=-1\dfrac25[/tex]

The edge of a cube is 4 inches.
The area of a cross section perpendicular to one face is
square inches, and its perimeter is
inches
Answer:
Sketch of a cube with side = 4 in as shown.
The shaded area is perpendicular to the right and left vertical faces of the cube, so the cross section is a square with each side equal to 4 in.
The area of the cross section is
4*4 = 16 in²
The perimeter of the cross section is
4+4+4+4 = 16 in.
Answer:
16 and 16

5x-2y=2 slope intercept form?
Answer:
[tex]y = \frac{5}{2}x-1[/tex]
Step-by-step explanation:
Slope-intercept form is represented by the formula [tex]y = mx + b[/tex]. So, to place the given equation in slope-intercept form, isolate the y on the left side and arrange the terms in that matching order. Remember, whatever you do to one side, do to the other:
[tex]5x-2y = 2\\-2y = -5x + 2\\\frac{-2}{-2}y = \frac{-5}{-2} x+\frac{2}{-2} \\y = \frac{5}{2} x-1[/tex]
So, the slope-intercept form is [tex]y = \frac{5}{2}x-1[/tex].

solve for y.
5x + 4 = -4y
Answer:
5x−4=y 5 x - 4 = y . Add 4 to both sides of the equation. Divide each term by 5 and simplify. Divide each term in 5x=y+4 5 x = y + 4 by 5 5 .

Write in equation in slope form of the line shown
Answer:
y=2x-5
Step-by-step explanation:
Slope intercept form is y=mx+b, with m being the slope and b being the y-intercept.
Slope is found through (y2-y1)/(x2-x1) and when the values are plugged in you get (-3-1)/(1-3) which equals -4/-2 or 2.
y=2x+b
Since b is the y-intercept, you plug in the value of the point where the line crosses over the y axis. In this case, that value is -5, so you get y=2x-5.
Solve for x.

See belowStep-by-step explanation:
Given the data set of 15 where:
Mean = 7Median = 6Mode = 5The minimum is 1 and the maximum is 10As per given we conclude
The set will have 7 numbers before 6 and 7 numbers afterSum of 15 numbers is 15*7 = 105The most used number is 5a) Possible set is:
1, 5, 5, 5, 5, 5, 5, 6, 9, 9, 10, 10, 10, 10, 10b) Add number 20, the set will be:
1, 5, 5, 5, 5, 5, 5, 6, 9, 9, 10, 10, 10, 10, 10, 20The mean is different as we have now more numbers with different sum:
(105 + 20)/(15 + 1) = 125/16 = 7.8125The median is different now and moves to the right as 20 added to the far right:
(6 + 9)/2 = 7.5The mode stays same as still most used number is 5:

Note: Used Elimination Method
Multiply the first equation by -2,and multiply the second equation by 1.
−2(−2x+y=3)
1(3x+2y=−15)
Becomes:
4x−2y=−6
3x+2y=−15
Add these equations to eliminate y:
7x=−21
Then we solve 7x = −21 for x:
7x = −21
7 7
(we Divide both sides by 7)
x=−3
Now that we've found x let's put it back in to solve for y.
Put down an original equation:
−2x+y=3
Substitute−3 for x in−2x+y=3:
(−2)(−3)+y=3
y+6=3(Simplify both sides of the equation)
y+6+−6=3+−6(Add -6 to both sides)
y= −3
Solution
(-3, -3)

Find the circumference and area of the circle to the nearest hundredth. Use 3.14 for π. Round to the nearest hundredth if necessary.
56 is the cm.
Answer:
56÷2=28
Circumference=2×3.142×r
c= 2×3.142×28=175.952
hundredth =175.95cm
Area=3.142×r^2
A= 3.142×28^2=2463.328
hundredth =2463.33cm^2

Step-by-step explanation:
There are 4 ropes. Each rope is 3 \large \frac{1}{4} feet long. Select the 3 expressions that would give the total length of the ropes. a \large 3\frac{1}{4}+3\frac{1}{4}+3\frac{1}{4}+3\frac{1}{4} b 4 x \large \frac{12}{4} c 4 x \large \frac{13}{4} d \large \frac{12}{4}+\frac{12}{4}+\frac{12}{4}+\frac{12}{4} e \large \frac{13}{4}+\frac{13}{4}+\frac{13}{4}+\frac{13}{4}
Answer:
The correct answers are;
4 * 3 1/4
3 1/4 + 3 1/4 + 3 1/4 + 3 1/4
13/4 + 13/4 + 13/4 + 13/4
Step-by-step explanation:
Given 4 ropes each 3 1/4 feet long
1 rope = 3 1/4 feet long
4 ropes = x
cross multiply
1 * x = 4 * 3 1/4
x = 4 * 3 1/4
Since 3 1/4 is in 4 places, the total length can also be expressed as;
3 1/4 + 3 1/4 + 3 1/4 + 3 1/4
We can also rewrite as an improper fraction
Since 3 1/4 = 13/4
Total length = 13/4 + 13/4 + 13/4 + 13/4
Share 720cm in the ratio 3:4:2:9
Answer:
120 cm, 160 cm, 80 cm, 360 cm
Step-by-step explanation:
The ratio 3:4:2:9 is the same as the ratio 3x:4x:2x:9x
We add all the terms of the second ratio:
3x + 4x + 2x + 9x = 18x
18x = 720
x = 40
3x = 3(40) = 120
4x = 4(40) = 160
2x = 2(40) = 80
9x = 9(40) = 360
Answer: 120 cm, 160 cm, 80 cm, 360 cm
