Answer:

475 students, 125 adults

Step-by-step explanation:

x + y= 600......equation 1

5x +9y= 3500.......equation 2

From equation 1

x +y = 600

x= 600-y

Substitute 600-y for x in equation 2

5(600-y) +9y= 3500

3000-5y+9y= 3500

3000+4y= 3500

4y= 3500-3000

4y= 500

y= 500/4

y= 125

Substitute 125 for y in equation 1

x + y= 600

x + 125= 600

x = 600-125

x= 475

Hence there are 475 students and 125 adults

$\huge\text{Hey there!}$

$\mathsf{5^{x - 2} = 5^8}$

$\mathsf{5^{x - 2} = 5\times5\times5\times5\times5\times5\times5\times5}$

$\mathsf{5^{x - 2} = 25\times25\times25\times25}$

$\mathsf{5^{x - 2} = 625\times625}$

$\mathsf{5^{x - 2} =390,625}$

$\large\textsf{Solving for the exponent:}$

$\mathsf{5^{x - 2} =390,625}$

$\large\textsf{Take the log (logarithm) to both of the sides:}$

$\mathsf{log(5^{x - 2} \rightarrow log(390,625)}$

$\large\textsf{Simplify it:}$

$\mathsf{(x - 2) \times(log (5)) \rightarrow log(390,625)}$

$\large\textsf{Simplify that as well:}$

$\mathsf{x - 2 = \dfrac{log(390,625)}{log(5)}}$

$\large\textsf{You get it: }\mathsf{x - 2 = 8}$

$\large\textsf{ADD by 2 to BOTH of the SIDES:}$

$\mathsf{x - 2 + 2 = 8 + 2}$

$\large\textsf{Simplify it:}$

$\mathsf{x = 8 + 2}$

$\mathsf{x = 10}$

$\huge\textsf{Therefore, your answer should be:}$

$\huge\boxed{\mathsf{x =} \frak{10}}\huge\checkmark$

△ACD∼△GHD , m∠ADC=23∘ , and m∠C=31∘ . Two similar triangles. The first triangle has vertices DAC. Angle A is an obtuse angle. Th

iVinArrow [24]

Answer:

126°

Step-by-step explanation:

The sum of angles in a triangle is 180°. Corresponding angles C and H of the similar triangles have the same measure, so you have ...

... ∠G + ∠H + ∠D = 180°

... ∠G + 31° +23° = 180° . . . . . . . subtract the numbers on the left to find ∠G

... 180° -54° = ∠G = 126°
