How we gonna show our work

Answer:

R=51

Step-by-step explanation:

6x-9+7x=121

add like terms:6x+7x=13x

13x-9=121

to cancel out (-9) and to isolate x, add on both sides

13x=130

divide into both sides

x=10

to solve for angle R

substitute 10 for x

6(10)-9

R=51

Which expression is equivalent to (4.5x10^2) + (6.0x10^3) and written in scientific notation?

A. 1.05 x 10^6
B 2.7 x 10^6
C. 6.45 x 10^3
D. 10.5 x 10^5

Answers

Your answer for this problem is c

The value of the expression (4.5 x 10²) + (6.0x10³) is 6.45 x 10³. Therefore, the correct option is C.

Scientific notation:

The given expression is the sum of two numbers written in scientific notation.

[tex](4.5\times 10^2)+(6.0\times 10^3)[/tex]

It can be written as:

[tex](0.45\times 10\times 10^2)+(6.0\times 10^3)[/tex]

[tex]=(0.45\times 10^3)+(6.0\times 10^3)[/tex]

[tex]=(0.45+6.0)\times 10^3[/tex]

[tex]=6.45\times 10^3[/tex]

The required expression in scientific notation is [tex]6.45\times 10^3[/tex].

Therefore, the correct option is C.

Answers

Answer:

16 square units

Step-by-step explanation:

The formula for the area of a right triangle is ab/2 (a and b both being legs).

First, we find the legs' length which is MK and JK.

Since both points J and K are on the same y level, we look at the X coordinates and see how far apart they are.

Since both points M and K are on the same x level, we look at the Y coordinate.

M is 4 points away from K, so the leg MK is 4 units long.

J is 8 points away from K, so the leg JK is 8 units long.

Plug this into the formula and we get

[tex]\frac{4*8}{2}[/tex]

[tex]\frac{32}{2} = 16[/tex]
