Regroup to express the number differently.

I think the answer is 19 tens since u take away a hundred, which is 10 tens and 10 tens + 9 tens equals 19 tens

What is the system linear equations?<br> y= -2x+19<br> y=x+17

tester [92]

First set them equal to each other

x+17=-2x+19

Solve the equation then...

3x=2

...and you would find x as 2/3

Plug that answer back in and you will find y=53/3

Hope this helps :-)

{(5²)} ³×5⁴}÷5⁷ simplify and express the following as exponent

Stels [109]

Answer:

The answer is 5³.

Step-by-step explanation:

You have to apply Indices Law :

${a}^{m} \times {a}^{n} ⇒ {a}^{m + n}$

${a}^{m} \div {a}^{n}⇒ {a}^{m - n}$

${ ({a}^{m} )}^{n} = {a}^{mn}$

So for this question :

$( {( {5}^{2}) }^{3} \times {5}^{4} ) \div {5}^{7}$

$= ( {5}^{6} \times {5}^{4} ) \div {5}^{7}$

$= {5}^{10} \div {5}^{7}$

$= {5}^{3}$

Tell whether the given value is a solution of the inequality.<br> 5x - 17 > 62; x = 13

andrezito [222]

Answer:

the given value x=13 is not a solution of the inequality

Step-by-step explanation:

we first need to solve this inequality (can treat the inequality like a normal equation to solve it)

5x-17 > 62

5x > 79

x>(79/5)

keep in mind that (79/5)=15.8

so x needs to be bigger than 15.8 in order to satisfy this inequality.

since 13<15.8 when x=13 it does not satisfy the inequality

therefore the given value x=13 is not a solution of the inequality
