1 answer:
mel-nik [20]3 years ago
7 0

Answer:

x = -17

Step-by-step explanation:

7(2x + 3) = 12x - 13

Distribute

7*2x +7*3 = 12x-13

14x +21 = 12x-13

Subtract 12x from each side

14x-12x+21 = 12x-12x-13

2x+21 = -13

Subtract 21 from each side

2x+21-21 = -13-21

2x = -34

Divide by 2

2x/2 = -34/2

x = -17

(1 point) a rectangular box has length 3 inches, width 13 inches, and a height of 4 inches. find the angle between the diagonal
Lapatulllka [165]

The length of the base diagonal (d) can be found using the Pythagorean theorem on length and width:

... d = √((3 in)² +(13 in)²) = √(9+169) in = √178 in

The tangent of the angle you want to find is the ratio of the height of the box to this length:

... tan(α) = 4/√178

Taking the arctangent, we have

... α = arctan(4/√178) ≈ 0.291285 radians

300 is 10 percent of her entire savings, 300+300=600

so 10%+10%=20%
