What is x in this equation .3=.5x-.7

NARA [144]

By solving the linear equation it can be obtained that

The value of x is 2

What is a linear equation?

At first it is important to know about equation

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation.

The given linear equation is

0.3 = 0.5x - 0.7

0.5x = 0.3 + 0.7

0.5x = 1

x = $\frac{1}{0.5}$

x = 2

The solution of this linear equation is x = 2

0.63 =<br> How do you convert this into a fraction

ohaa [14]

Answer:

63/100

Step-by-step explanation:

first, since the decimal goes to the hundredths place, you would put it into a fraction as 63/100. Then you see if you can simplify it from there. It cannot be simplified, so your answer will just be 63/100.

Write an equation in point-slope form of the line that passes through the point 4,-1and has slope of -5

Basile [38]

Answer:

y=-5+19

Step-by-step explanation:

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was -5. So you can right away fill in the equation for a line somewhat to read:

y=-5x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(4,-1). When x of the line is 4, y of the line must be -1.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the -5 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (4,-1).

So, why not plug in for x the number 4 and for y the number -1? This will allow us to solve for b for the particular line that passes through the point you gave!.

(4,-1). y=mx+b or -1=-5 × 4+b, or solving for b: b=-1-(-5)(4). b=19.

Can anybody do all of number 1??

MAXImum [283]

Answer:

You use the formulas for the shapes

Cylinder= 2×π×r×h+2×π×r² π×r²×h

Cone= $\pi*r(r+\sqrt{ h^{2} +r^{2}} )$ π×r²× $\frac{h}{3}$

Square Prism= 2×a²+4×a×h a²×h

↑a=base edge

Step-by-step explanation:

Surface Area Volume

Cylinderical Head ≈282.74 ≈314.16

Conical Hat ≈170.13 ≈78.54

Right Cylinder Torso ≈471.24 ≈785.4

Right Cylinder Arm ≈56.55 ≈25.13

Square Prism Leg =224 =192
