Answer:

1.25x-0.7

Step-by-step explanation:

0.5x−0.6+0.75x−0.1

=0.5x+−0.6+0.75x+−0.1 Combine Like Terms:

=0.5x+−0.6+0.75x+−0.1

=(0.5x+0.75x)+(−0.6+−0.1)

=1.25x+−0.7

Answer:

Step-by-step explanation:

x + 31 equals 2x - 8 because both pair of expressions must add up to 180

Answer:

54 hours

Step-by-step explanation:

So, first of all subtract the money she has from the total amount.

540-60=480 She still needs $480. So divide this number by the amount she gets in an hour. (9)

480/9 =53.33333 since she can't work half hours, i rounded up.

Answer:

The answer is 81°

Step-by-step explaination:

To start, the top right angle and the bottom left angle are alternate interior angles, making them congruent. The same justification goes for the angles in the top left and bottom right. With this in mind, 37° + 44° = 81°. Every triangle's angles always add up to 180°, meaning that 180° - 81° = 99°. Because angle n and the angle we just found to be 99° are supplementary, they also add up to 180°, therefore 180° - 99° = 81° which is the value of angle n.

Answer:

7/10 *10/10 is 70/100 or 7/10 so equal

Step-by-step explanation:

the product is 7/10.

it is 10/10which simplifies to 1(divide by 10)

so it wouldn't change

I don't really know what your question is asking for but I can tell you there's a quadratic formula that solves for x-ints. There's a quadratic equation which is Ax + bx + c = 0.

Answer:

(228.663 ; 241.337)

Step-by-step explanation:

Given that:

Mean (m) = 235

Standard deviation (s) = 28

α = 95%

Zcritical at 95% = 1.96

Sample size (n) = 75

The confidence interval of the population mean can be obtained using the relation :

Mean ± Error

Error = Zcritical * (s/sqrt(n))

Error = 1.96 * (28/sqrt(75))

Error = 1.96 * 3.2331615

Error = 6.33699654

Error = 6.337

Lower boundary = 235 - 6.337 = 228.663

Upper boundary = 235 + 6.337 = 241.337

(228.663 ; 241.337)

Answer:

Inequality: c + 3 > -27

Answer:

x-axis = (2, -3)

y-axis = (-2, 3)

y = x (3, 2)

y= -x (-3, -2)

Step-by-step explanation:

x-axis = (2, -3) The point is below the x-axis.

y-axis = (-2, 3)  The point is left of the y-axis

y = x (3, 2) Plot the line y = x. The point is on the other side of the line.

y= -x (-3, -2) Plot the line y = -x. The point is on the other side of the line.

Answer:

D

Step-by-step explanation:

The given equation  (x – 1)² + (y + 1)² = 9 represents a circle with the center (1, -1) and a radius of 3.

The circumference, which is the distance around the object, the diameter, which is the length of a circle measured from one end to the other and passing through its center, and the radius, which is equal to half of the diameter, are the three key characteristics.

Given an equation  (x – 1)² + (y + 1)² = 9

The general coordinate equation of a circle is:

(x-h)² + (y - k)² = r²

Where,

(h, k) is the center of a circle,

"r" is the radius of the circle.

Comparing with the general equation of a circle:

h = 1,

k = -1

r² = 9

r = 3

thus, the given equation  (x – 1)² + (y + 1)² = 9 represents a circle with the centre (1, -1) and the radius of 3.

Answer:

Step-by-step explanation:

Hi!

We're given that the perimeter is 76. A triangle's perimeter is given by the sum of all of the sides. So, we'll find the lengths of the sides of the triangle and add them.

This is an isosceles triangle. The legs of an isosceles triangle are equal. In this problem, we're given the length of one leg: 3x-4. That means that the length of the other leg is also 3x-4. Now, the last side of the triangle is x ("base is x).

2(3x-4) + x = 76

6x-8+x=76

7x-8=76

7x=84

x=12

Let's check our answer.

3(12) - 4 =36-4 = 32

32 times 2 = 64 +12 =76

Correct!

2.) smaller number

11, 16, 12, 15

Step-by-step explanation:

Given two numbers in each as follows :

A.) 18 ____ 12 ; 18 > 12

B.) 11 _____14 ; 14 > 11

C.) 15 ____ 17 ; 17 > 15

D.) 19 ____ 11 ; 19 > 11

Color the smaller number ::

20 ____ 11 ; 11 < 20

16 ____ 19 ; 16 < 19

12 ____ 13 ; 12 < 13

15 ____ 20 ; 15 < 20

Answer:

−1<x<2 or 2<x<3

Step-by-step explanation:

You need to find the critical points of the inequality first. Factor must be at left side of equation. Then set factors to 0. Be sure to check intervals in between critical points (test the intervals to see if they work/fit).
