Find 2 consecutive integers that the sum is 149?

Write an equation. To do this, make one integer equal to x, and the other equal to x+1. Set these equal to 149. Your equation should read x+(x+1)=149. Solve. To do this, add the two x's together. Your equation is now 2x+1=149. Get your x's alone. First, subtract 1 from both sides. Now the equation is 148=2x. Divide both sides by 2 to get x alone. You now have x=74. Plug this value back into the original equation to find your value for the other integer, and you have the two integers as 74 and 75. Hope this helps!

First you have to find the slope with the equation y2 - y1 / x2 - x1 , then once you have found the slope (slope = -2) you simply plug it into the point slope formula. y-0 = -2(x-5) solving it algebraically you should arrive at Y=-2x+10. (the 5 and 0 were plugged in are two of the X and Y points of the line which is why we plugged them into the X and Y values of the equation)

zheka24 [161]

Answer:

FV= $4,948.16

Step-by-step explanation:

Giving the following information:

Number of periods (n)= 10

Interest rate (i)= 2.15% compound interest annually

Present value (PV)= 4,000

<u>To calculate the future value, we need to use the following formula:</u>

FV= PV*(1+i)^n

FV= 4,000*(1.0215^10)

FV= $4,948.16

George walked on a treadmill 16 3/4 miles over 4
slamgirl [31]

Answer:

4 3/16 miles a day

Step-by-step explanation:

16 3/4 miles in 4 days

Divide 16 3/4 by 4

16 3/4 = 67/4

4 = 4/1

To divide you multiply by the reciprocal(flip of the numerator and denominator)

67/4 ÷ 4 = 67/4 x 1/4 = 67/16

67/16 = 4 3/16

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

Find the sum of 34x+6 and −(14)x−9
Semmy [17]

Answer:

20x - 3

Step-by-step explanation:

<em>Finding the sum means adding the two together; combining like-terms.</em>

34x + 6 - 14x - 9

<em>34x</em><em> and </em><em>-14x</em><em> both have the variable </em><em>x</em><em> with them so we can combine those terms. Since </em><em>6</em><em> and </em><em>-9</em><em> have no variables with them, we can combine them.</em>

20x - 3
