1) Eliot and William went hiking. They went at the same speed. Eliot's hike was 8 miles, and William's hike was 12 miles. It too

Vitek1552 [10]

Answer:

1) 2 hours

2) 96 miles

Step-by-step explanation:

1) Eliot and William went hiking. They went at the same speed. Let x mph be their speed.

Elliot:

Distance = 8 miles

Speed = x mph

Time $=\dfrac{8}{x}$ hours

William:

Distance = 12 miles

Speed = x mph

Time $=\dfrac{12}{x}$ hours

It took Eliot $40\ min=\dfrac{40}{60}\ hour=\dfrac{2}{3}\ hour$ less than William, then

$\dfrac{8}{x}+\dfrac{2}{3}=\dfrac{12}{x}\\ \\\dfrac{2}{3}=\dfrac{12}{x}-\dfrac{8}{x}\\ \\\dfrac{2}{3}=\dfrac{4}{x}\\ \\2x=3\cdot 4\ \ [\text{Cross multiply}]\\ \\2x=12\\ \\x=6\ mph$

So, William's hike was

$\dfrac{12}{6}=2$

hours long.

2) Initially:

Distance = 120 miles

Speed = 55 mph

Time $=\dfrac{120}{55}=2\dfrac{10}{55}=2\dfrac{2}{11}\$ hours

Final:

Speed = 44 mph

Time $=2\dfrac{2}{11}$ hours

Distance $=44\cdot 2\dfrac{2}{11}=44\cdot \dfrac{24}{11}=4\cdot 24=96\ miles$

Simplify the expression. Write the answer using scientific notation. (9 x 10)^2(2 x 10)^10

Valentin [98]

Answer:

Step-by-step explanation:

To multiply scientific notation, multiply each part of the number.

(9 x 10)^2(2 x 10)^10 = (9*2) * (10^ 2 + 10) = 18 * 10 ^ 12

Since scientific notation can only have a digit in the ones place from 1-9. 18*10^12 becomes 1.8*10^13.

The solution is B.

What is the solution for the system of equations?

SIZIF [17.4K]

Substitute value of y from equation (1) in equation (2),

5x-4(5-3x) = -3

5x-20+12x = -3

17x=17

x = 1

Substitute it in equation (1),

y = 5-3(1)

y = 5-3 = 2

So, the values (x,y) = (1,2)
