Answer:

x=34

Step-by-step explanation:

x+(x+12)+100=180

2x+12=80

2x=68

x=34

Answer:

\boxed{x \degree =  34\degree}

Step-by-step explanation:

=  > (x + 12) \degree + 100 \degree + x \degree = 180 \\  \\  =  > x \degree + 12 \degree + 100 \degree + x \degree = 180 \degree \\  \\  =  > 2x \degree + 112 \degree = 180 \degree \\  \\  =  > 2x \degree = 180 \degree - 112 \degree \\  \\  =  > 2x \degree = 68 \degree \\  \\  =  > x \degree =  \frac{68}{2} \degree  \\  \\  =  > x \degree =  34\degree

Triangle MNO is isosceles. Find the value of y and the measure of Angle O.
Andrews [41]

Answer:

y = 14

Angle O is 41 degrees

Step-by-step explanation:

From the question, since we have an isosceles triangle, then the base angles are equal

This means that the angle at M is (4y-15) too

Mathematically, the sum of the angles in a triangle is 180 degrees

Thus;

7y + 4y-15 + 4y-15 = 180

15y-30 = 180

15y = 180+ 30

15y = 210

y = 210/15

y = 14

Angle O is 4y-15

= 4(14) -15 = 56-15 = 41 degrees

Simplify by combining like terms: -4\left(2x-y\right)+y+5\left(x+y\right)−4(2−)++5(+) − 4 ( 2 x − y ) + y + 5 ( x + y ) ; use NO
netineya [11]

Answer:

<em>-3x+10y</em>

Step-by-step explanation:

Given the expression -4\left(2x-y\right)+y+5\left(x+y\right), we are to simplify by combining the like terms. On simplification we have;

= -4\left(2x-y\right)+y+5\left(x+y\right)

Open the parenthesis:

= -4(2x)-4(-y)+y+5(x)+5(y)\\\\= -8x+4y+y+5x+5y

Collect the like terms:

= -8x+5x+4y+y+5y

Sum up the resulting expression

= -8x+5x+4y+y+5y\\= -3x+10y

<em>Hence the required expression on simplification is -3x+10y</em>

If \$1000 is deposited into an account that earns 3.25\% simple interest per year, how much money will be in the account after 7
Andrei [34K]
<h3>Answer: 1227.50 dollars</h3>

======================================================

Explanation:

The simple interest formula to use is

A = P*(1+r*t)

where,

A = account value after t years (original deposit + interest)

P = 1000 = amount deposited (principal)

r = 0.0325 = annual interest rate in decimal form

t = 7 = number of years

So,

A = P*(1+r*t)

A = 1000*(1+0.0325*7)

A = 1227.50

Side note: you've earned A-P = 1227.50-1000 = 277.50 dollars in total interest
