Answer: 3x

Step-by-step explanation: since they are all like terms, you start from the left in the parentheses and subtract 3x from -7x which equals -4x. Then add 3x to 4x which is 7x. Then add -4x to 7x and you get your answer which is 3x

Answer:

A positive 3x

Step-by-step explanation:

since both parts have the same variable you could add them or subtract them together

(3x-7x)+(3x+4x)

You will subtract 3x-7x which will give you a negative 4x

You will do the same on the other side

Add 3x+4x and it will give you a positive 7x

-4x+7x=will give you an positive 3x

Hopes this helps

if the circumference of the shield is 100.48inches, nits radius is 16 inches and the area of the front of the shield is about 803.84 square inches.

proof

circumference = 2x r x Pi implies r =circumference / 2Pi=100.48/2x3.14=16

area = Pi x r²=3.14 x 16²=804.84

Twice the greater of two consecutive odd intergers is 13 less than three times the lesser. Find the intergers

erastova [34]

Answer:

$\large\boxed{15, 16}$

Step-by-step explanation:

2 consecutive integers represented as variables:

x, x + 1

Greater one: x + 1

Lesser one: x

Write as an equation

2(Greater) + 13 = 3(Lesser)

Substitute in known values

2(x + 1) + 13 = 3(x)

Multiply

2x + 2 + 13 = 3x

Subtract 2x from both sides of the equation

2 + 13 = x

Add 2 + 13 to simplify

x = 15

Lesser = x = 15

Greater = x + 1 = 15 + 1 = 16

$\large\boxed{15, 16}$

Hope this helps :)
