Your answer would be 8n+10 because you have to combine like terms. you would do 3n+3n+n+n which gives you the 8n and then you would do -5+-5+10+10 which gives you the 10 and when you put it all together, you get 8n+10.

ANSWER: 8n+10

Solve for x<br><br> (picture is included below)

Anna11 [10]

Solve for x:

4x - 7 = 3

Add 7 to both sides

4x = 10

Divide both sides by 4

x = 10/4

Simplify:

x = 5/2

Answer for question 1: x = 5/2

13 + 2x/3 = 15

Multiply both sides by 3

39 + 2x = 45

Subtract 39 from both sides

2x = 6

Divide both sides by 2

x = 3

Answer for question 2: x = 3

10x + 7 = 15

Subtract 7 from both sides

10x = 8

Divide both sides by 10

x = 8/10

Simplify

x = 4/5

Answer for question 3: x = 4/5

posledela

Answer:

1 pounds of apples $=$ $\$ 1·25

1 pounds of cheese $=$ $\$ 7

1 pounds of coffee beans $=$ $\$ 5·5

1 pounds of fudge $=$ $\$ 9

1 pounds of pumpkin $=$ $\$ 0·88

Step-by-step explanation:

Unit Rate is the ratio between two different quantities with different units

The ratio of cost per items is

$=$ $\frac{dollars}{pounds}$

4 pounds of apples $= \$ 5

4 pounds $= \$ 5

Divided 4 both the side

1 pounds of apples $=$ $\$ 1·25

$\frac{1}{2}$ pounds of cheese $= \$ 3·50

$\frac{1}{2}$ pounds $= \$ 3·50

Divided $\frac{1}{2}$ both the side

1 pounds of cheese $=$ $\$ 7

$\frac{3}{2}$ pounds of coffe beans $= \$ 8·25

$\frac{3}{2}$ pounds $= \$ 8·25

Divided $\frac{3}{2}$ both the side

1 pounds of coffee beans $=$ $\$ 5·5

$\frac{3}{4}$ pounds of fudge $= \$ 6·75

$\frac{3}{4}$ pounds $= \$ 6·75

Divided $\frac{3}{4}$ both the side

1 pounds of fudge $=$ $\$ 9

$\frac{25}{4}$ pounds of pumpkin is $= \$ 5·50

$\frac{25}{4}$ pounds $= \$ 5·50

Divided $\frac{25}{4}$ both the side

1 pounds of pumpkin $=$ $\$ 0·88

Joe is hiking a trail that is 30 miles long. after several days, he is two times as far from the beginning of the trail as he is

lora16 [44]

In order to answer this question let's suppose,
Joe is x miles from the beginning and y miles from the end. These assumptions are necessary to answer further:

Now,
x=2y
x+y=30
plugging in x=2y in the above equation
2y+y=30
3y=30
y=10

Hence, according to our calculations, Joe has to hike 10 miles further
