$\frac{x}{2}$ = $\frac{6}{1.5}$

The 2 right triangles are similar and so the ratios of corresponding sides are equal

The corresponding sides are x and 2, 6 and 1.5, hence

$\frac{x}{2}$ = $\frac{6}{1.5}$

This equation basically says that a number plus 3/5 equals 2 so we can simply:

2 - 3/5 = x

Therefore x equals 1 & 2/5 or 1.4

Writey=1/8 x+7 in standard form using integers.

sineoko [7]

Answer:

x - 8y = - 56

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

y = $\frac{1}{8}$ x + 7

Multiply through by 8 to clear the fraction

8y = x + 56 ( subtract 8y from both sides )

0 = x - 8y + 56 ( subtract 56 from both sides )

- 56 = x - 8y, that is

x - 8y = - 56 ← in standard form

Tricia got a 6% raise on her weekly salary. The raise was $30 per week. What was her original weekly salary in dollars per week?

serious [3.7K]

Answer: Original salary = $500

Step-by-step explanation: Tricia got a 6% raise on her weekly salary. The

raise was $30 per week.

Let x be the original salary

x times the raise percentage = raise amount

6%= 6/100=0.06, raise amount = 30

Now we solve for x

Divide by 0.06 on both sides

Original salary = $500
