Answer: x=7/5 or 1 2/5
Step-by-step explanation:
Given
x+3/5=2
Subtract 3/5 on both sides
x+3/5-3/5=2-3/5
x=10/5-3/5 (This is to convert 2, as a integer, to a fraction in order to ease the
x=7/5 operation)
If 2x + 7 = -21, what does 2 - x equal?
Answer:
16
Step-by-step explanation:
First, we solve for x.
[tex]2x+7=-21\\2x=-28\\x=-14[/tex]
We now evaluate 2-x, plugging in -14 for x.
[tex]2-x\\2-(-14)\\2+14\\16[/tex]
12.5
Step-by-step explanation:2x+7=-21
2x+7-7=-21-7
2x=-28
2x/2=-28/2
x=-14
2-x=?
2-(-14)
2+14=16

21 = -4h +13-h
Send help:(
Answer:
h = -8/5
Step-by-step explanation:
21 = -4h +13-h
simplify the right side
21 = -5h + 13
subtract 13
21 = -5h + 13
-13 - 13
8 = -5h
divide by -5
8 = -5h
/-5 /-5

Two galaxies are shown. Galaxy U: Dust, gas, and stars in the shape of a pinwheel, relatively small in size. Galaxy NGC 1427A: Dust, gas, and stars in a nonuniform arrangement spread out over a large area. How are NGC 1427A and U different? How are they the same?
Answer:
NGC 1427A has no general shape, so it is an irregular galaxy. U has a bulge in the center and arms, so it is a spiral galaxy. They are similar in that both contain plenty of dust and gas. Both also have active star-forming sites.
Step-by-step explanation:
NGC 1427A is an irregular galaxy with no discernible shape. The spiral galaxy U has a bulge in the middle and arms.
What is a galaxy?A galaxy is a massive clump of gas, dust, and billions of stars and their solar systems bound together by gravity.
The first galaxies were discovered in the 17th century by Charles Messier, who had no idea what they were at the time.
Messier, a proficient comet viewer, noticed many more fuzzy objects in the sky that he knew were not comets.
We would discover 64 galaxies the size of the Milky Way in a cube that now holds one galaxy the size of the Milky Way.
NGC 1427A is an irregular galaxy because it lacks a general shape. U is a spiral galaxy, since it contains a bulge in the center and arms.
They are comparable in that they both have a lot of dust and gas. Both have active star-formation sites.
Hence, they are comparable in that they both have a lot of dust and gas.

Convert from the given standard form of a linear equation to the slope-intercept form of a linear equation
Answer:
y=-1/5x+1
Step-by-step explanation:
divide both sides by 5: 1/5x+y=1
subtract 1/5x so y is alone since slope-intercept has y=mx+b: y=-1/5x+1
The slope-intercept form of the line x + 5y = 5 is y = - (1/5)x - 1.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, An equation of a line in the standard form x + 5y = 5.
We know the equation of the slope-intercept of the line is y = mx + b.
Therefore, The slope-intercept form of the equation x + 5y = 5 is,
5y = - x - 5.
y = - (1/5)x - 1.

Solve for x and find de mesures of Angule B
Answer:
x=9.4
b=77.2
Step-by-step explanation:
a+b=180
as they are interior angles
(6x-48)+(4x+38)=180
6x-48+4x+38=180
6x+4x+38-48=180
10x+86=180
10x=180-86
10x=94
x=94/10
x=9.4
b=(4x+38)
b=4x+38
b=4(9.8)+38
b=39.2+38

4(x-7)=2x-6 (show work)
Answer:
x = 11
Step-by-step explanation:
Given
4(x - 7) = 2x - 6 ← distribute parenthesis on left side
4x - 28 = 2x - 6 ( subtract 2x from both sides )
2x - 28 = - 6 ( add 28 to both sides )
2x = 22 ( divide both sides by 2 )
x = 11

43.82 divided by 7.4
Answer:The answer is 2191/370
Answer:
5.92297297297...
Step-by-step explanation:
First, I made it into a fraction and multiplied the numerator and denominator by 10: [tex]\frac{43.82}{7.4}[/tex]
Then I put it into long division format and solved.
So, these are the following steps that I did:
1. Divide 438 by 74 to get 5.
2. Multiply the quotient digit left (5) by the divisor 74.
3. Subtract 370 from 438, add a decimal point to the solution, and divide to find the remainder.
In the end, I got 5.92297297297... [ 297 will continue to repeat so this is a repeating decimal. ]

Step-by-step explanation:
Calories burned varies directly to miles run. Dustin burns 190 calories for every 2 miles he runs. Part 1: Find the value of k. Part 2: Write the equation for the direct variation. Part 3: Find how many calories Dustin will burn after running 7 miles.
Answer:
C = km
k = 95
C = 665
Step-by-step explanation:
Calories burned varies directly to miles run.
Let
C = calories burned
m = miles
C = km
Dustin burns 190 calories for every 2 miles he runs
C = 190
m = 2
C = km
190 = k2
Divide both sides by 2
k = 95
equation for the direct variation.
C = km
Find how many calories Dustin will burn after running 7 miles.
C = ?
m = 7
k = 95
C = km
C = 95 × 7
= 665
