Answer:

1) 380,000 and 59,000

2) 657,000

Step-by-step explanation:

631,000 + 26,000

631000 = 600000 + 30000 + 1000 + 0 + 0 + 0

26000 = 0 + 20000 + 6000 + 0 + 0 + 0

600000 + 50000 + 7000 + 0 + 0 + 0 = 657000

1-7x-7=15 Solve Please I don't know.

DIA [1.3K]

Answer:

Step-by-step explanation:

So first we combine like terms on the left

1-7=-6

then we have

-7x-6=15

next we add 6 both sides

-7x-6=15

+6 +6

-7x=21

then we divide -7 each side

we get

x=-3

What are the coordinates of the orthocenter of △JKL with vertices at J(−4, −1) , K(−4, 8) , and L(2, 8) ?

kompoz [17]

Answer:

K(-4,8) is the ortho center.

Step-by-step explanation:

In a right angled triangle, The vertex of the right angle is the ortho center.

Here we are given

J(-4,-1), K(-4,8) & L(2,8)

Using distance formula we get

$JK^{2}= (-4+4)^{2}+ (8+1)^{2}=0+81=81$

$KL^{2}= (-4-2)^{2}+ (8+-8)^{2}=36+0=36$

$JL^{2}= (-4-2)^{2}+ (8+1)^{2}=36+81=117$

So we can say that

$JK^2 + KL^2=JL^2$

By converse of pythagorean theorem we get

Hence the Vertex of the right angle is K(-4,8)

K(-4,8) is the ortho center.

The express the expression 6×10 to the -7÷3×10 to the -3rd is equivalent to what?

vlabodo [156]

$(6\times10^{-7})\div(3\times10^{-3})=\dfrac{6\times10^{-7}}{3\times10^{-3}}=\dfrac{6}{3}\times10^{-7-(-3)}=2\times10^{-7+3}\\\\=\boxed{2\times10^{-4}}\\\\Used:\\\\\dfrac{a^n}{a^m}=a^{n-m}$
