Answer:

7x-14=2x+11

Step-by-step explanation:

Collect like terms

7x-2x=11+14

5x=25

Divide both sides by the coefficient of x(5).

x=25/5

x=5

Answer:

x=5

Step-by-step explanation:

The first thing we need to do in this equation is to get both of the x variables on the same side.

How do we do this you might ask? Well, need to cancel out the 2x so all we have left is one x variable. We can do this by subtracting 2x from each side.

The important thing to remember when solving equations like these is that whatever you do to one side, you MUST do to the other side.

2x-2x is 0 so that cancels out the 2x on the right side. 7x-2x=5x so we are left with that for our left side.

Now, we have to get rid of the constants (the non-variable numbers)

Let’s cancel out the 14 on the left side so the x is still by itself.

Add 14 to -14 to cancel it out. Do the same to the right side. 14+11=25 so that 25 is what we are left with on the right side.

Our equation becomes 5x=25

Now we have to completely isolate the x with no coefficient. We do this by dividing 5 by each side. But remember the rule, whatever you do to one side, you must do to the other. So we divide 25 by 5 as well.

5x/5 is x and 25 divided by 5 is 5

So our final answer is…

X=5

Hope this helped and please award brainliest.

Have a great day!

Multiply 0.006 by 3.08. Express in standard form​
olga_2 [115]

Answer:

1.848 × 10^-2

Step-by-step explanation:

0.006 = 6 × 10^-3

3.08 = 3.08 × 10^0 (10^0 is equal to 1)

(6 × 10^-3) × (3.08 × 10^0) = 18.48 × 10^-3 = 1.848 × 10^-2

Y= -x +3 and y = x - 1
inysia [295]

Answer:

x=2 and y=1

Step-by-step explanation:

Rewrite equations:

y=−x+3;y=x−1

Step: Solve

y=−x+3

Step: Substitute−x+3foryiny=x−1:

y=x−1

−x+3=x−1

−x+3+−x=x−1+−x(Add -x to both sides)

−2x+3=−1

−2x+3+−3=−1+−3(Add -3 to both sides)

−2x=−4−2x−2=−4−2

(Divide both sides by -2)

x=2

Step: Substitute2forxiny=−x+3:

y=−x+3

y=−2+3

y=1(Simplify both sides of the equation)

Hope this Helps you :)

Please help <br> The diagram shows a 5ft student standing near a tree
Novosadov [1.4K]

Answer:

25 ft

Step-by-step explanation:

The diagram shows two triangles that are similar.  Similar triangles have equal angles and sides that are proportional to each other.  Since the base of each triangle is given, we can find the proportion of the sides:

\frac{smaller}{larger}=\frac{8}{40}=\frac{1}{5}

Given the ratio of the smaller to larger triangle, we can set up a proportion to find the missing height of the larger triangle:

\frac{1}{5}=\frac{5}{x}, where 'x' represent the height of the tree

cross-multiply:  x = (5)(5) or 25 ft
