Note that if we add each side of the 2 equations, y will cancel out:

-12x-y+(17x+y)=6+4

5x=10

x=2


Substituting x=2 in either of the equations, we find the value of y.

Let's use the first equation:

-12x-y=6

-24-y=6

-y=24+6

-y=30, so y=-30.

Thus, the solution is (2, -30)

Answer: C

A box turtle marcos found is 0.115 of a meter long.what is this length in expanded form
castortr0y [4]

We are given length of turtle marcos = 0.115 of a meter.

We need to write this length in expanded form.

We know we have, first digit on left side of decimal is the value of ones in place value chart.

On the right side of decmal we read numbers as Tenths, Hundredths, Thousandths, Ten Thousandths.

We have

0 at Ones place, then decimal, then 1 at tenths place, again 1 at hundredths place and then 5 at thousandths place.

0.115 = 0 + 1 tenth + 1 hundredth + 5 thousandths.

Or 0.115 = 0 + 0.1 + 0.01 + 0.005.

Therefore, final expanded form is 0 + 0.1 + 0.01 + 0.005.

Please answer. I have attached the picture of the question and I promise I will give brainliest.
Vaselesa [24]

Answer:

first is the chart so for the time row its 4, 8, 12, 16, 20 & distance is 3, 6, 9, 12, 15

I added the complete graph down below, basically what i did wasplot the points from the chart so (4,3), (8,6), (12,9), (16, 12), and (20,15)

so for example for (4,3) you would first find 4 on the x-axis or the time line and then find 3 on the y-axis and so on let me know if you can see the picture:)

(Multiple choice/ Most Brainly will be rewarded)
GaryK [48]

Answer:

3

Step-by-step explanation

you have to do (2^3)(a^4*3)(b^2*3) which gets you 8a^12b^6

then you have (8a^12b^6)*(3ab^4) so you do (8*3)(a^12+1)(b^6+4)

which equals 24a^13b^10

and therefore the answer is 3
