Hey there,

148 = 2x + 6(x + 10)

148 = 2x + 6x + 60

148 = 8x + 60
-60 - 60

88 = 8x
/8 /8

11 = x


6x + 4(-x - 14) = -42

6x -4x - 56 = -42

2x - 56 = -42
+ 56 + 56

2x = 14
/2 /2

x = 7


-101 = 7x -4(-3x - 8)

-101 = 7x + 12x + 32

-101 = 19x + 32
- 32 - 32

-133 = 19x
/19 /19

-7 = x

Hope I helped :)

Solve the system of equations algebraically.<br><br> {Y=(x-2)^2+2<br> {Y+4=3x
nikdorinn [45]

Answer:

(5, 11) and (2, 2)

Step-by-step explanation:

y = (x-2)² + 2

y + 4 = 3x

(x-2)² + 2 + 4 = 3x

x² - 4x + 4 + 6 = 3x

x² - 7x + 10 = 0

(x - 5)(x - 2) = 0

x - 5 = 0, x = 5

x - 2 = 0, x = 2

y = (5-2)² + 2 = 11

(5, 11)

y = (2-2)² + 2 = 2

(2, 2)

Hey can anyone help find the missing measurement pls
Komok [63]

Answer:

? ≈ 6.5 yd

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

here A = 13.3 and h = 4.1 , then

\frac{1}{2} × 4.1b = 13.3 ( multiply both sides by 2 to clear the fraction )

4.1b = 26.6 ( divide both sides by 4.1 )

b = ? ≈ 6.5 yd ( to the nearest tenth )

A bag contains 5 blue marbles, 3 red marbles, and 2 yellow marbles. You select a marble at random. What is P(yellow) ?
Tasya [4]
There are a total of 10 marbles. Out of those 2 are yellow.

So, the probability of picking a yellow marble is 2/10, or 1/5 simplified.


As a percentage, this is 20%

Hope this helps :)

Answer:

The number would be 9!

Step-by-step explanation:

If you divided the new number, 17259, by 11, you would get 1569! If you added any other number 1-10, other than 9, to the original number, you would get a decimal in the end.
