Answer:

7/6

Step-by-step explanation:

So first you want to find the common denominator. Which would be 6. Then you want to multiply 3x3 and 1x2. So it would now be, 9/6-2/6=7/6

S=Steve. S+4=Kevin. S+s+4=26. Combine: 2s+4=26. Subtract 4: 2s=22. Divide by 2: s=11. Steve ran 11 miles. :)

The diagonals of rectangle ABCD intersect at point E. If AE = 2x + 5, and BD = 5x + 2, what is AC?

Mkey [24]

C. 42 units

Step-by-step explanation:

I have attached a diagram to help you understand this problem. By looking at the diagram you can see that AE is half of BD, and that BD will be equal to AC. So we need to figure out the length of line BD to get AC.

To do this, you will multiply the length of AE by 2 and set it equal to BD.

$2(2x+5)=5x+2$

Then distribute, multiply what is in the parentheses by 2.

$4x+10=5x+2\\\\$

Subtract 4x from both sides.

$10=1x+2$

Subtract 2 from both sides.

$8=1x$

x = 8

Now that we have x, we can plug it into the equation to find BD.

$5 * 8 + 2=42$

BD is equal to 42 units, so we know...

AC = 42 units

Can you help me? the first who does and get it right gets brainlest

Hunter-Best [27]

Answer: y=2/3x-5

Explanation: The first thing I do is look for the y-intercept which is where the line goes through the y-axis, for this equation it's -5; then the slope the point goes up one and goes right 1.5, then put it into whole numbers so I'll times them by 2 so the slope is 2/3

With those you can put it into slope-intercept form: y=2/3x-5
