Mathematics

NNADVOKAT [17]3 years ago

Answer:

The number is 5

Step-by-step explanation:

If we need to find the hidden number, Which for simplicity's sake we will denote as "n", lets first write out the equation.

"2 x [n + (-3)] = 4"

We can work through this problem backwards. if we need two times the sum of "n" and (-3) to get to 4, the only number that can be multiplied by 2 to get a product of 4 is 2, so "n" + (-3) must equal 2. so, From here, we can figure out that since 5 + (-3) equals 2, "n" Must equal 5. so, if we plug in 5 for "n" the equation looks like this:

"2 x [5 + (-3)] = 4"

So, since the equation makes sense, the answer is, "n = 5"

Animal y=5.4x+34<br> person y=12x+8.5 y is weight x is years. when is the weight the same
I am Lyosha [343]

Answer:

Step-by-step explanation:

Animal                 Person

y = 5.4x + 34       y = 12x + 8.5; where y - weight, x - years

looking for when weight (y) is the same, so we need

animal weight (y) = person weight (y)

            5.4x + 34 = 12x + 8.5

        <u>   -5.4x           -5.4x</u>

                      34 = 6.6x + 8.5

                  <u>  -8.5             -8.5</u>

                   25.5  = 6.6x     divide both sides by 6.6

                         x = 3.86  years

not sure if you need your answer in decimal or what, but you can adjust accordingly.

As a nurse, part of your daily duties is to mix medications in the proper proportions for your patients. For one of your regular
spayn [35]

Answer:

10 milligrams of Medication A

Step-by-step explanation:

We'll write proportions/ratios for this:

20:16 is the usual proportion, and x:8 is this week's dose. The ratio from A to B has to be equal, so

20/16 = x/8

Cross-multiply:

(20)(8) = (16)(x)

160 = 16x

divide both sides by 16

x = 10

Please let me know if you have questions about this answer.

-4-x=6 so what does x equal
Elza [17]

Answer:

x=-10

Step-by-step explanation:

Add 4 to both sides to work towards isolating x: -x=10

Multiply both sides by -1 to isolate x: x=-10

Coincidentally, that's your answer. Therefore x=-10.
