15x + 12(10 - x) = 1417 and 3

Step-by-step explanation:

The number of people who have two-course meal is (10 - x)

Correct equation is:

15x + 12(10 - x) = 141

Solving for x:

15x + 120 - 12x = 1413x = 141 - 1203x = 21x = 7

Answer:

Number who have three-course meal = 7Number who have two-course meal = 3

Answers:

1) 15x + 12(10 - x) = 141

2) 7 and 3

15x + 12(10 - x) = 141

15x + 120 - 12x = 141

3x = 141 - 120

3x = 21

x = 7

can you tell me how to solve this problem using substitution step by step?

y = -2x - 9 and 6x - 5y = - 19

Answers

Answer:

x = -4

Step-by-step explanation:

The first equation tells us what y is equal to. We then substitute wherever there is a y with what y equals.

y = -2x - 9

6x - 5y = -19

6x - 5(-2x-9) = -19

6x + 10x + 45 = -19

16x + 45 = -19

16x = -64

x = -4

help me answer this please!!!

Answers

Answer:

39.6 ft.

Step-by-step explanation:

Height of the top of the goal post would be x + 5.5

So for we need to calculate x first,

For x:

[tex]tan\ \theta = \frac{perpendicular}{base}\\\\tan\ 61=\frac{x}{20}\\\\20*tan61=x\\\\x=20*1.732\\\\x=34.64\ ft[/tex]

So height of the top of the goal post would be 34.64 + 5.5 which is

39.64 ft. rounding it to nearest tenth would be 39.6ft.

Answer:

7.436 × 10 ^6

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
