Answer:

$7.50

Step-by-step explanation:

Thus, a product that normally costs $30 with a 25 percent discount will cost you $22.50, and you saved $7.50. You can also calculate how much you save by simply moving the period in 25.00 percent two spaces to the left, and then multiply the result by $30 as follows: $30 x .25 = $7.50 savings.

Asanji left the science museum and drove toward the lake at an average speed of 45 km/h. Sometime later Huong left driving in th
Cloud [144]

Answer:

Asanji drove for 5 hours before Huong caught up

Step-by-step explanation:

Let the time for which Asanji drove alone is "X" hours

Asanji and Huong met after three hours of driving of Huong.

Total time for which Asanji drove = X+3 hours

Thus, distance travelled by Asanji in X+3 hours is equal to distance travelled by Huong in 3 hours

45 ( X+3) = 75 (3)\\

On solving the above equation, we get -

45 X + (45 *3) = 75 *3\\45 X = (75-45)*3\\45 X = 30 *3 \\X = \frac{30 *3}{45} \\X = 2

Asanji drove for 3 + 2 = 5 hours before Huong caught up

Write and solve an equation to find the unknown side length x (in feet).
Setler79 [48]

Answer:

11.9 feet

Step-by-step explanation:

We want to find the value of 'x' and we are asked to set up an equation to find the value of x. In equation we must remember to get all the numerical values to one side and all the non-numerical values to the other while remembering to keep the equation balanced for example if we add 4 on one side we must do it to the other side to keep the equation balanced so,

→ x + 5.2 + 11.1 + 6.4 = 34.6

⇒ Simplify equation

→ x + 22.7 = 34.6

⇒ Minus 22.7 from both sides to isolate x

→ x = 11.9 feet

Question 2 (5 points)
IrinaK [193]

Answer:

x - y + 5 = 0

Step-by-step explanation:

Given:

  • Line passes through (-2,3) and (2,7)

Required:

  • Find the equation of the line

The equation of the line passing through two points is given by

\frac{y-y_{1} }{y_{2}- y_{1} } =\frac{x_{}- x_{1} }{x_{2} -x_{1} }

So, \frac{y-3}{7-3} =\frac{x-(-2))}{2-(-2)}

\frac{y-3}{4} =\frac{x+2}{2+2}

\frac{y-3}{4} =\frac{x+2}{4}

Now, y-3 = x+2

On rearranging,

x - y + 3 + 2 = 0x - y + 5 = 0

Therefore, the equation of the line is x - y + 5 = 0.
