Answer:

Step-by-step explanation:

x - 8/5 = 2/4

x = 2/4 + 8/5

x = 2*5/4*5 + 8*4 / 5*4

= 10/20 +  32 / 20

= ( 10+32 ) / 20

= 42 /20

=  21/10 = 2 1/10

Answer:

x = 2.1

Step-by-step explanation:

  1. Calculate 8/5 and 2/4 into numbers: 8/5 = 1.6, 2/4 = 0.5
  2. Add 1.6 to 0.5: 1.6 + 0.5 = <u>2.1</u>

Which of the following sets of numbers could represent the three sides of a right triangle
MissTica

Answer:

The pythagorean theorum states that the longest side of the right triangle (hypotenuse), squared, is equal to the sum of the squares of the 2 other sides

Its expressed as so:

c^2=a^2+b^2

Therefore,

{36, 48, 60} is correct

Can someone please do this for me?
katrin [286]

Answer:

x= 105

y= 40

Step-by-step explanation:

3y=4y-40 because they are alternate interior

Solve for y.

y=40

4y-40=x+15 because they are vertical angles.

Substitute 40 in for y.

4(40)-40=x+15

Solve.

x=105

Find the solutions to the system of equations. Select all that apply. Y=x^2-1 y=2x-2
Sliva [168]

Answer:

Option C (1, 0)

Step-by-step explanation:

We have a system with the following equations:

y = x ^ 2-1\\\\y = 2x-2

The first equation is a parabola.

The second equation is a straight line

To solve the system, substitute the second equation in the first and solve for x.

2x-2 = x ^ 2 -1

Simplify

x ^ 2-2x + 1 = 0

You must search for two numbers that when you add them, obtain as a result -2 and multiplying both results in 1.

These numbers are -1 and -1

Therefore

x ^ 2-2x + 1= (x-1)(x-1)\\\\x ^ 2-2x + 1= (x-1)^2=0

Finally the solutions are

x = 1\\y =0

Find a point-slope form for the line that satisfies the stated conditions. Slope , passing through (-5,4)

I really need this question answered

By:

I don't see a value for the slope. We need that to set the equation, otherwise I can write an unlimited number of equations that pass through (-5,4).

I'll assume a slope so that you can see how the procedure would work. I like 6, so we'll assume a slope of 6.

The equation for a straight line has the form y = mx + b, where m is the slope and y is the y-intercept, the value of y when x = 0. We want a line that has slope 6, so:

y = 6x + b

We need to find b, so substitute the point (-5,4) that we know is on the line:

4 = 6*(-5) + b and solve for b

4 = -30 + b

b = 34

The line is y = 6x + 34

When a number x is divided by 24 the remainder is 23 and when it is divided by 36 the remainder is 35. Find the least number tha
Snezhnost [94]

Answer:

7 is the answer. If a number can be divided by 36 then it can also be divided by 12 which is 3*12 therefor the remainder will be 19-12 which is 7. When 19 is divided by 36, the remainder is 19 and so 19 must be a number. When 19 is divided by 12 the remainder is 7.
