How would u solve this liner system?

1 answer:

8 0

We can solve it by substitution: y = - 3 x - 1.
So the 2nd equation becomes:
4 x + 3 * ( - 3 x - 1 ) = 2
4 x - 9 x - 3 = 2
- 5 x = 2 + 3
- 5 x = 5
x = 5 : ( - 5 ) = - 1
y = - 3 * ( - 1 ) - 1 = 3 - 1 = 2
Answer: x = - 1, y = 2.

How do I draw a visual model using 1/6 of 18? Please help. I'm asking for my 5th grader. Thank you!

svp [43]

Answer:

Theory

Step-by-step explanation:

Take any 18 objects

For example in this case

Take 18 chocolates

$\frac{1}{6}$ means one sixth , which practically means how many groups of 6 can be formed

So, Try to divide 18 into groups of 6

Count how many such groups are formed(it will be 3)

So one sixth of 18 is 3

That is, 18 comprises of 3 groups, each group containing 6 chocolates

Wirte a decimal for each of the following 9x100+2x10+3x0.1+7x0.001

borishaifa [10]

We need to perform multiplication and addition property for this problem to represent the final result in decimal form. So, the expression is,

9x100+2x10+3x0.1+7x0.001 .

Now 9 x 100= 900

2 x= 10= 20

3x0.1= 0.3

7x 0.001=0.007

Now we can all the numbers. Hence,

900+20+0.3+0.007=920.307

So, the decimal number is 930.307.

7(1 - 76) - 2b = -197

noname [10]

Answer:

b= -164

Step-by-step explanation:

calculate the difference

7x(-75)-2b= -197

multiply the numbers

-525-2b= -197

move the constant to the right- hand side and change the sign

-2b= -197+525

add

-2b=328

divide

b= -164
