Step-by-step explanation:

Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).

Answer:

[tex]x(x - 1) - {x}^{2} + 2x = 5 \\ {x}^{2} - x - {x}^{2} + 2x = 5 \\ \therefore \: x \: = 5[/tex]

Answer:

x=5

Step-by-step explanation:

[tex]x(x-1)-x^2+2x=5[/tex]

expand by using distributive property

[tex]x^2-x-x^2+2x=5[/tex]

simplify

x=5

check work by substituting 5 into the original equation and simplify

use PEMDAS

[tex]5(5-1)-5^2+2(5)=5[/tex]

[tex]5(4)-25+10=5[/tex]

add and subtract  (left to right)

20-25+10=5

5=5

The equation is true, thus x=5

Step-by-step explanation:

63+36+X = 180 (interior angles of a triangle equal 180)

X = 180-99

X= 81

X+Z= 180(angles on a straight line adds up to 180)

81+y= 180

Z=180-81

Z =99

13+Z+Y=180

13+99+Y=180

Y=180-112

Y=68

5x^3 + 6x^2 - 45x - 54

x^2( 5x + 6) -9(5x-6)

(5x+6)(x^2 - 9)

5x+6=0 x^2-9=0

5x= -6 x^2= 9

x= -6/5 x= -3 or 3

Answer:

Step-by-step explanation:

So first of all, you can rearrange your equations:

4x + 7x = 11 can be rearranged and simplified to x = 11/7

x = y + 1 can be rearranged to y = x - 1

Then you can graph them like normal by plugging in points. It should look like the following picture

Answer: (a.) 32x-20  4*8-4*5        (b.) 22y    11y+11y

(0.05)²

CHANGE 0.05 INTO SCIENTIFIC NOTATION

= (5 × 10^-2)²

SQUARE IT OFF EACH NUMBER

= 5² × (10^-2)²

=25 × 10^-4

=0.025

Answer:

.05×.05=.0025 because it is squared

19 (questions right) / 28 (total) = 0.67857142857

Round to the tenth, 67.9.

Answer:

Kanisha's test score is approximately 67.8571 percent.

Step-by-step explanation:

19/28 is about 67.8571, just under the 68 percent passing score. However, if her test score is rounded up, it will exactly meet the lowest passing score.

Answer:

63.55

Step-by-step explanation:

1. Given that Javier's pay rate is $10.25 per hour, let's find the combined amount he earned from Monday and Tuesday by multiplying the hours worked by 10.25.

2. Now, let's add 24.6 and 38.95 to get how much he earned:

Therefore, Javier earned 63.55 dollars and cents on those two days.

Answer:

rearrange the question

y - 5x = 8.................(1)

y - 8x = 9..................(2)

make y the subject formula in eqn. (1)

y = 8 + 5x................(3)

substitute

8 + 5x - 8x = 9

-3x = 1

x = -⅓

y = 8 + 5x

y = 8 + (-⅓)

y = 23/3

Answer:

Answer: Option D

Answer: Option DStep-by-step explanation:

• In distributive property, we multiply the factor to each term in the bracket. So that the reverse is true.

Take an example;

[tex] \dashrightarrow \: { \rm{x(y + z)}}[/tex]

• To apply distributive property, mulyiply both y and z by x following the addition operation.

summary:

[tex] \dashrightarrow \: { \rm{xy + xz}}[/tex]

→ The expression above is the expansion using distributive property.

• Back to the question, we are given a factorised expression;

[tex]{ \rm{6(8 - \frac{1}{3} )}} \\ [/tex]

• To apply the distributive property, multiply 8 and ⅓ by 6:

[tex] \dashrightarrow \: { \boxed{ \boxed{ \rm{ \: (6 \: • \: 8 - 6 \: • \: \frac{1}{3}) }}}} \\ [/tex]

Step-by-step explanation:

look at the graph

for 47. it's asking when the input (aka the X) is equal to 1, what is the output (aka the Y). so just go to the graph where X=1 and read the Y
