2 1/7 + 3/7 (3x-5)= - 4

2 1/7 + (9/7)x - 15/7 = - 4

15/7 + (9/7)x - 15/7 = - 4

(9/7)x  = - 4

x = - 4 * 7/9 = - 28/9 = - 3 1/9

Answer is   - 28/9  or  - 3 1/9.

Mrs. Ramiriz is making pies to sell at the local farmer’s market. It costs her $5 to make each pie, plus a one-time cost of $30
Elena L [17]
<span>We can represent the number of pies she makes to be x. We also need to add $30 to the equation to take the baking supply cost into consideration. The Cost can be represented by C. C = 5x + 30 is the equation to use to determine the Cost! 5 times the number of pies she makes plus the $30 for baking supplies! If we look at just the cost when she doesn't sell any pies, we can say x = 0 That means C = 5(0) + 30 or C = 30, it means that she has to pay $30 or the Cost is $30 when she sells no pies. This makes sense since the baking supplies were $30. Are you with me so far?</span>

A monument in a park is shaped like a square pyramid. The dimensions are shown in the net. What is the surface area of the monum
vampirchik [111]

The surface area of the monument shaped like a square pyramid is 14 m².

<h3>Area </h3>

Area is the amount of space that is occupied by a two dimensional shape or object.

From the diagram

Area of each triangle = (1/2) * base * height = (1/2) * 2 * 2.5 = 2.5 m²

Area of square = length * length = 2 m * 2 m = 4 m²

Surface area of monument = 4(2.5) + 4 = 14 m²

The surface area of the monument shaped like a square pyramid is 14 m².

Write the equation for the area (A) in terms of width (w) of a playground if the length (l) is twice as long as the width (w)
Crazy boy [7]
It will be a system of equations.

A=1*w
l=2w

Solve by substitution.
