3x+11 in a right angle

1 answer:

Anna11 [10]2 years ago

To find the x value...
First of all, we know that all angles in the triangle total up to 180 degrees.
Also, we know that because it is a right angle, there is a little square that means 90 degrees.
we are given one of the angles as 25 degrees

Let's make an equation to solve for the value x then the angle measure
3x + 11 + 25 + 90 = 180
combine like terms
3x + 126 = 180
subtract 126 from both sides to start isolating the variable x
3x = 54
now we will divide both sides by 3 to isolate the variable x
x = 18

Now we aren't done
plug in the value of x into the angle we have to solve for
3x + 11
3 ( 18) + 11
54 + 11
65
The missing angle measure is 65 degrees

Hope this helps :)

200+12m= 644
subtract 200 from both sides
12m= 444
divide both sides by 12
m= 37

What is the ratio of quarters to nickels in a dollar

sleet_krkn [62]

For quarters we have:

$0.25x = 1$

Where,

x: number of quarters

Clearing x we have:

$x = \frac{1}{0.25}\\x = 4$

For nickels we have:

$0.05y = 1$

Where,

y: number of nickels

Clearing y we have:

$y = \frac{1}{0.05}\\y = 20$

Then, the ratio of quarters to nickels is:

$\frac{x}{y}= \frac{4}{20}$

Simplifying we have:

$\frac{x}{y} = \frac{1}{5}$

Answer:

The ratio of quarters to nickels in a dollar is:

$\frac{x}{y}= \frac{1}{5}$

A 40% sugar solution is added to an 85% sugar solution to create 1800 mL of a 60% solution. How much of each solution is used? (

denis-greek [22]

Answer:

Number of ml of 40% sugar = x = 1000mL

Number of ml of 85% sugar used = y = 800mL

Step-by-step explanation:

Let the

Number of ml of 40% sugar = x

Number of ml of 85% sugar used = y

From the above question, our system of equations is given as:

x + y = 1800mL ....... Equation 1

x = 1800 - y

40% × x + 85% × y = 60% × 1800mL

0.4x + 0.85y = 1080.... Equation 2

We substitute 1800 - y for x in Equation 2

0.4(1800 - y) + 0.85y = 1080

720 - 0.4y + 0.85y = 1080

- 0.4y + 0.85y = 1080 - 720

0.45y = 360

y = 360/0.45

y = 800mL

Solving for x

x = 1800 - y

x = 1800 - 800

x = 1000mL

Therefore,

Number of ml of 40% sugar = x = 1000mL

Number of ml of 85% sugar used = y = 800mL
