Answer:

You are subtracting 15 from both side to isolate 10 a it would look like this afterwards:

10a=65-15

And you continue to solve

You subtracted 15 from both sides so you can isolate 10a.

What's the distance between the points (–9,2) and (–4,2)?
algol [13]

If you are asking for the slope it is a zero slope because...

2-2 equals 0 and you don't need to solve the bottom because the top is a zero

but a horizontal slope is when the zero is on the bottom.

btw- I guarantee I am right because i am a Indian. My wisdom comes from God. Jesus Christ!!!!:):):)

(PLEASE HELP!!!!)Mario has money in savings. He also has a job with hourly pay. After
Olin [163]

Answer:

X = savings, p= pay per hour

X+4p = 86 - - - - (1)

X+6p=104 - - - - - (2)

Re arrange equation (1)

X=86-4p-----(3)

Substitute (3) in (2)

86-4p +6p=104

86+2p=104. (subtract 86 from both side)

2p = 18. (divide by 2 from both side)

Then p =$9

By substitute in equation (1)

X = $50

An antelope can run a speed of 61 miles per hour. What is this speed in yards per second? Round to the nearest hundredth
DochEvi [55]

Answer:

= 29.82 yards/second

Step-by-step explanation:

The speed is given in the problem.  We just need to convert its units.  The multiplicative identity (that is, 1) may be used to change the units without changing the value.  (note:  do you know what the additive identity is?)

     61 miles per hour

    (61 miles) / (1 hour)

   (61 miles)/(1 hour)*1

   ((61 miles)/(1 hour))*((5280 feet)/(1 mile))

   ((61 miles)/(1 hour))*((5280 feet)/(1 mile))*((1 yard)/(3 feet))*((1 hour)/(60 minutes))*((1 minute)/(60 seconds))

      note:  miles, feet, hours, minutes cancel out; leaving yards per second

    (61/1)*(5280/1)*(1/3)*(1/60)*(1/60)   yards/second          (note: I write that way to paste into Excel)
