Step-by-step explanation:

10X+ 180= 500

10X= 500-180

10X= 320. .....divine both sides by 10 to solve for X

X = 32.

check

10(32)+180 = 500

320+180 =500

500 =500...confirmed

Choose the correct proportions.

cestrela7 [59]

Answer:

Options A, B and C are CORRECT PROPORTIONS

Step-by-step explanation:

Option A

3:5 = 6:10

The LHS must equal the RHS

3:5 is in it's lowest term.

6/10 will be in it's lowest term by dividing the numerator and denominator by 2.

6/10 = 3/5

Option B

3/6 and 5/10.

Diving 3/6 fractions by 3

= 1/2

Dividing 5/10 fraction by 5

= 1/2

Option C

Dividing 6/3 by 3 = 2

Dividing 10/5 by 5 = 2

Thats how you work through equivalent proportional fractions

A cooking show currently has about 223,00 regular viewers. The number of regular viewers has been decreasing at a rate of 4.7% p

Mazyrski [523]

The best prediction for the number of regular spectators that the program will have in 6 years is obtained with the following formula:
Pf = Po×(1-b) ^ t
Where:
Pf = final population
Po = initial population
b = decrease rate
t = timpo in years
So:
Pf = 223.00×(1-0.047) ^ 6
Pf = 167,056
The answer is the last option.

Discrete Math - Find X

Snezhnost [94]

Answer:

x = 70°

Step-by-step explanation:

Clockwise from top, call the three tangent points A, B, and C. Central angle AXC is the supplement of the marked external angle, so is 140°. Arc AB is bisected by the upper ray of angle x; and arc BC is bisected by the lower ray of angle x. That is to say x is half the measure of arc AC, so is 70°.

Attached is the output of a geometry program. The angle at lower left is 40° as in the given figure. The central angle α (70°) remains the same as tangent point C is moved around, which is to say that the measure of the angle α does not depend on the dimensions of the triangle containing α. It just depends on the fact that the triangle is tangent to the circle.

PLS, HELP WILL GIVE BRAINIEST THX AND 30 POINTS 4 BEST ANSWER Jenna just opened a checking account at the bank. Within the first

nadya68 [22]

A) Deposits: +34.98; +51.02; +51.22
Withdrawals: -5.23; -5.22; -7.89
B) -7.89, -5.23, -5.22, +34.98, +51.02, +51.22
The smallest amount will be the largest withdrawal, as it takes away from the account; the largest amount will be the largest deposit, as it adds to the account.
C) She would have $216.88.

98 + 34.98 = 132.98 + 51.02 = 184.00 + 51.22 = 235.22 - 7.89 = 227.33 - 5.23 = 222.10 - 5.22 = 216.88

A line contains the points (-26, -37) and (32, -61)

Slav-nsk [51]

The slope of line through given points is -12/29

Step-by-step explanation:

Given points are:

(-26, -37) and (32, -61)

Let

(x1,y1) =(-26, -37)

And

(x2,y2) = (32, -61)

Slope (steepness) of a line, denoted by m, is given by the formula

$m = \frac{y_2-y_1}{x_2-x_1}$

Putting the values

$m = \frac{-61-(-37)}{32-(-26)}\\\\=\frac{-61+37}{32+26}\\\\=\frac{-24}{58}\\\\=-\frac{12}{29}$

Hence,

The slope of line through given points is -12/29
