Answer:
One solution
Step-by-step explanation:
Hi,
3(x + 5) = -4x + 8
3x + 15 = -4x + 8
7x + 15 = 8
7x = -7
x = -1

Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for B
B = 180° - (90 + 39)° = 180° - 129° = 51°
Using the tangent and sine ratios in the right triangle for b and c
tan39° = =
Multiply both sides by b
b × tan39° = 27 ( divide both sides by tan39° )
b = ≈ 7.5 ( to the nearest tenth )
sin39° = =
Multiply both sides by c
c × sin39° = 27 ( divide both sides by sin39° )
c = ≈ 28.0 ( to the nearest tenth )
Answer:
16
Step-by-step explanation:
1st group = 30% or .3 as a decimal
.3 * 40 = 12
2nd group = ate 7
Third group = 1/8 or .125 as a decimal
.125 * 20 = 5
12 + 7 + 5 = 24
40 -24 = 16
Answer:
24 times
Step-by-step explanation:
It is given that :
The length of the side of square A = 5 inches
The length of the side of square B = 25 inches
Therefore, area of square A = 5 x 5
= 25 square inches
Similarly, area of square B = 25 x 25
= 625 square inches
Therefore, number of times the square B is bigger than the square A is given by :
= 24
Thus the square B is 24 times bigger than square A

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The surface area of the composite = (6 * 8) + 2(8 * 3.6) + 2(0.5)(6 + 2 + 6 + 2)(3) + (8)(2 + 6 + 2) = 233.6 cm²
The surface area of the composite figure shown in the figure attached is 233.6 cm²
