Wouldn’t the answer be 48 if I’m correct because it’s talking about renting a bike for a hour and if you do the math 72-24 is 48 hours hope it’s right

Which is a correct first step for solving this equation? 2x−1(5−3x)=4x+2

GuDViN [60]

Answer:

distribute

Step-by-step explanation:

so multiply -1 with 5 and -3

this turns it to 2x(-5+3x)=4x+2

then you multiply 2x to -5 and 3x

so on...

Roberto needs some roofing tiles to be cut from a large tile. How many tiles that are each 14 3/8 inches in length can he cut fr

ratelena [41]

Answer:

6 tiles.

Step-by-step explanation:

We have been given that Roberto needs some roofing tiles to be cut from a large tile.

Let us find the number of tiles that can be cut from a larger piece of tile.

$\text{Tiles can be cut from large piece}=\frac{\text{length of large tile}}{\text{length of each small tile}}$

Let us convert our given mixed fractions in improper fractions.

$14\frac{3}{8}=\frac{115}{8}$

$100\frac{3}{8}=\frac{803}{8}$

Now let us substitute our given values in above formula.

$\text{Tiles can be cut from large piece}=\frac{803}{8}\div\frac{115}{8}$

Since we know that dividing a fraction by a fraction is same as multiplying the reciprocal of second fraction with the first fraction.

$\text{Tiles can be cut from large piece}=\frac{803}{8}\times\frac{8}{115}$

Upon cancelling out 8 from numerator and denominator we will get,

$\text{Tiles can be cut from large piece}=\frac{803}{115}$

$\text{Tiles can be cut from large piece}=6.9826086956521739$

We can see that number of tiles turns out to be 6.98, although it is very close to 7, but we cannot round our answer because the 7th tile will still be shorter than the required measure. Therefore, we can only cut 6 tiles of the required size from the given large tile.

What is the equation of the line perpendicular to y=1/2x+6 that passes through the point (4, 1)?

Oksana_A [137]

Answer:

Step-by-step explanation:

Find the slope of the perpendicular line.

The slopes are related by the formula

m1 * m2 = - 1

Since m1 is 1/2, m2 must be -2

So far what you have is y = -2x + b

Find the y intercept (b).

The new line goes through (4,1)

x = 4

y = 1

1 = -2(4) + b

1 = - 8 + b

b = 1 + 8

b = 9

The answer is

y = - 2x + 9

X-2y=4 How to solve this

WARRIOR [948]

Since x does not contain the variable to solve for, move it to the right side of the equation by subtracting x from both sides
.−2y=−x+4
divide each term by −2 and simplify.
 the answer is y=x/2−2

slope= 1/2
y-intercept = -2
