Answer:

x=4, y=-2

Step-by-step explanation:

x = 3y + 10 \\ x =  - 8y -12\\ now \\ 3y  + 10 =  - 8y - 12 \\ 3y + 8y =  - 12 - 10 \\ 11y =  - 22 \\ y =  \frac{ - 22}{11}  \\ y =  - 2 \\ again \: putting \: the \: value \:of \: y \\ x = 3y + 10 \\ x = 3( - 2) + 10 \\ x =  - 6 + 10 \\ x = 4

*IGNORE THE ANSWERS*<br> This is 2nd grade math. I forgot how to solve these equations. Help:)
Mazyrski [523]

Answer:

a. 14

b. 7

Step-by-step explanation:

a. First we must add all the animals together,

Total Animals:

Birds: 6

Fish: 5

Mammals: 11

Reptiles: 3

Therefore our equation is:

6 + 5 + 11 +3 = 25.

Now, we must subtract by the number of mammals:

25 - 11 = 14

So our answer for a. is 14!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

b. So for this problem we must compute mammals + fish and than birds + reptiles. After we figure that out we must subtract them!

Mammals + Fish =

11 + 5 =

16

Next,

Birds + Reptiles =

6 + 3 =

9

Now, let us subtract them,

16 - 9 =

7

So our answer for b. is 7 more animals!

Simply this expression. Which like terms can she combine 12-4x+3
prohojiy [21]

like terms include terms that you can add/sub/mult/div - certain terms..

for example 23 and 7 are like terms, 4x and 56x are like terms....


here-> 12 and 3 are like terms so you can put them together:

12 + 3 - 4x

then you can simplify it:

15 - 4x is your answer (most simplified)

PLEASE HELP! THIS IS DUE TOMORROW! Much appreciated.
denis23 [38]

Answer:

Step-by-step explanation:

1a) angle x and angle y are corresponding angles. Both angles lie on the same side of the transversal. Since the lines are parallel, the angles are equal.

1b) angle x and angle y are interior angles on the same side of the transversal. Since the lines are parallel, the angles are equal supplementary.

1c) angle x and angle y are corresponding angles. Both angles lie on the same side of the transversal. Since the lines are parallel, the angles are equal.

1d) angle x and angle y are alternate interior angles. They are between the parallel lines and alternate sides of the transversal. Since the lines are parallel, the angles are equal.
