Mathematics
2 answers:
Basile [38]3 years ago
6 0

Answer: x=2

Step-by-step explanation:

1. Regroup terms.

1+4x=7x-5

2. Subtract 4x from both sides.

1=7x-5-

3. Simplify  7x-5-4x  to  3x-5.

1=3x-5

4. Add 5 to both sides.

1+5=3x1+5=3x

5. Simplify  1+5  to  6.

6=3x

6. Divide both sides by 3.

​3/​6=x

7 Simplify 3​/6 to  22.

2=x

8 Switch sides.

x=2

1+4.x= -5+7.x
you take the 1 and -5 add them
= -4
then you have the 4.x and the 7.x
the x’s leave them subtract 4 from 7
it’s 3x now
so now you have -4=3x
divide and you will have what x equals

Sally was walking to Ocean Front Housing Complex, In miles, how far is her distance?
Vanyuwa [196]

Answer:

Sally is 10 miles

The coordinate ofthe deli is (1, -1)

Step-by-step explanation:

✍️Coordinate of Sally = (-3, 2)

Coordinate of Ocean Front = (5, -4)

The distance of Sally to Ocean Front Housing Complex = the distance between point (-3, 2) and (5, -4).

Use the distance formula, d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}, to calculate the distance between (-3, 2) and (5, -4):

d = \sqrt{(5 -(-3))^2 + (-4 - 2)^2}

d = \sqrt{(8)^2 + (-6)^2}

d = \sqrt{64 + 36}

d = \sqrt{100} = 10

✅The distance of Sally is 10 miles

✍️the coordinate of Deli would be half the distance between Sally and Ocean Front.

Therefore, use the midpoint formula to calculate the coordinate of the midpoint between Sally (-3, 2) and Ocean Front (5, -4).

Midpoint of (-3, 2) and (5, -4).

M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})

Plug in the values

M(\frac{-3 + 5}{2}, \frac{2 +(-4)}{2})

M(\frac{2}{2}, \frac{-2}{2})

M(1, -1)

✅The coordinate ofthe deli is (1, -1)

Find the value of the missing coefficient in the factored form of 27f^3 + 125g^3. 27f^3+125g^3=(3f+5g)(9f^2-?fg + 25g)^2
7nadin3 [17]

Answer:

15

Step-by-step explanation:

The formula for factoring a sum of cubes is:

a^3+b^3=(a+b)(a^2-ab+b^2)

We have a=3f and b=5g here.

So a*b in this case is 3f*5g=15fg.

The ? is 15.

Solve the equation below for x.<br><br> -1<br> 2(3x - 4) = 11
kumpel [21]
If the -1 is not included, then your answer is 3.17.

2(3x-4)=11

3x2=6 and -4x2= -8

6x-8=11

+8 +8

6x=19

/6 /6


X= 3.17
