Answer:

The value of x = 7

Step-by-step explanation:

To solve this, we will have to fist of all know that the sum of all the angles in a right-angled triangle is 180 degrees.

In addition to that, since the triangle is a right-angled triangle, automatically, one of the angles is = 90 degrees

The next thing to do is to add all the angles together and equate them to 180 degrees.

Angle WXZ + Angle ZXY + 90 = 180 degrees

7x+8 + 5x-2 + 90 = 180

12x + 96 = 180

12x = 84

x = 7

Answer:

B. 200 doses

Step-by-step explanation:

Given,

1 dose is required for 100 mg,

Since, 1 mg = 0.001 g,

⇒ 100 mg = 0.1 g

⇒ 1 dost is required for 0.1 g,

Thus, the ratio of doses and quantity ( in gram ) is $\frac{1}{0.1}=10$

Let x be the doses required for 20 grams,

So, the ratio of doses and quantity is $\frac{x}{20}$

$\implies \frac{x}{20}=10$

$\implies x=200$

Hence, 200 doses can be obtained from 20 grams of the drug.

Option 'B' is correct.

A box of 36 candles cost $27.00 at that price per candle, how much would 5 candles cost?

erma4kov [3.2K]

Answer:

$3.75

Step-by-step explanation:

Candles = C

36C = $27.00

Divide both sides of the equation by 36

C = 0.75

The cost per candle is $0.75

Multiply by 5 to get the cost of 5 candles

$3.75

A linear function has a slope of Negative StartFraction 7 Over 9 EndFraction and a y-intercept of 3. How does this function comp

dem82 [27]

It has the same slope and the same y-intercept, that is, option a is the right choice.

A linear function in the slope-intercept is written as y = mx + b, where m represents the slope of the line and b represents the y-intercept.

We are given two linear functions and are asked to compare them.

First linear function:

Slope (m) = -7/9.

y-intercept (b) = 3.

Therefore, the linear function is: y = (-7/9)x + 3.

Second linear function:

Function given: y + 11 = (-7/9)(x - 18)

or, y + 11 = (-7/9)x + (-7/9)(-18)

or, y = (-7/9)x + 14 - 11 = (-7/9)x + 3.

Therefore, slope (m) = (-7/9)

y-intercept (b) = 3.

Therefore, we can say that it has the same slope and the same y-intercept, that is, option a is the right choice.
