Answer:

-2

Step-by-step explanation:

since the base are the same you add the exponent.

4x+2 + 2x-1= -3x-17

4x+2x +3x =-17-2+1

9x =-18

x=-2

Emily needs enough Fabric for 3 1/2 hats. Since she has half a hat done. If each bag requires 1 2/7 ft of Fabric, how much fabri

kow [346]

first off let's convert the mixed fractions to improper fractions.

$\stackrel{mixed}{3\frac{1}{2}}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}} ~\hfill \stackrel{mixed}{1\frac{2}{7}}\implies \cfrac{1\cdot 7+2}{7}\implies \stackrel{improper}{\cfrac{9}{7}}$

she already did half a hat, so we can say $\cfrac{7}{2}-\cfrac{1}{2}\implies \cfrac{7-1}{2}\implies 3$

so she only needs enough fabric to make 3 more full hats, we know each one uses 9/7 ft, so

$3\cdot \cfrac{9}{7}\implies \cfrac{27}{7}\implies 3\frac{6}{7}$

What are the steps to solving this? 70-8x=56+x

guapka [62]

Answer:

x = 14/9

Step-by-step explanation:

70 - 8x = 56 + x

- 8x - x = 56 - 70

- 9x = - 14

- x = - 14/9

x = 14/9

What are the coordinates of B

Kitty [74]

The coordinates of B are (14, -10).

<h3>How to find mid point?</h3>

The midpoint is already know . we can use it to find the coordinates of B.

Therefore,

(xₙ, yₙ) = (x₁ + x₂ / 2, y₁ + y₂ / 2)

Hence,

M(5, - 4) and A(-4, 2)

The coordinates of B are as follows:

(5, - 4) = (-4 + x₂ / 2 , 2 + y₂ / 2)

5 = -4 + x₂ / 2

10 = -4 + x₂

x₂ = 14

hence,

-4 = 2 + y₂ / 2

-8 = 2 + y₂

y₂ = - 10

Therefore, the coordinates of B are (14, -10)

The results of the car race are shown below.Explain how to determine who drove the fastest.

gizmo_the_mogwai [7]

Answer:

Evans was the fastest

Explanation:

The relation between velocity, time and distance is as follows:

$velocity = \frac{distance}{time}$

1- For Cutwright:

We have the time = 84 minutes and the distance = 35 laps

This means that:

velocity = $\frac{35}{84}$ = 0.61667 lap/minute

2- For Evans:

We have time = 96.6 minutes and distance = 42 laps

This means that:

velocity = $\frac{42}{96.6}$ = 0.43478 lap/minute

3- For Loza:

We have time = 102.6 minutes and distance = 38 laps

This means that:

velocity = $\frac{38}{102.6}$ = 0.37037 lap/minute

Based on the above calculations, we can note than Evans was the fastest

Hope this helps :)
