True.

You can't simplify this any further. y=-x is the equation of a line.

x1/5

Please note that there are infinitely many solutions. The slopes of two perpendicular lines have a product of minus 1. The line is in slope-intercept form, so it is easy to read off the slope: -5. The line perpendicular to it must have a slope of -1 / -5, or 1/5. In other words, the equation of the perpendicular line is y = (1/5)x + c; you can replace c with any number you want.

There appears to be no equation in the question: only some disjoint expressions. Expressions cannot be solved.

well you divide by ten

that's it

the answer is 0.33333

-7

7/100

11(eleven)

49/16 = (7^2)/(4^2) = (7/4)^2 = ((4/7)^-1)^2 = (4/7)^-2

Thus as (4/7)^2 = 49/16 and 49/16 = (4/7)^-2

(4/7)^x = (4/7)^-2

Therefore x = -2.

Hint: to multiply by 10, just add a zero...

You use volume measurement to measure water and other liquids such as cooking or pouring a cup of water.

You measure the house temperature with a thermometer.

You measure weight (or mass) with a scale to weigh yourself or your food.

You measure velocity (and acceleration) while driving.

You measure distance, length or size with a ruler, or a meter stick or any other measurement tool.

Five divided by two equals 2.5.

24,000,000 cc

It is [4m-1, (4m-2)/3]

Without knowing the plus or minus values of many of the given terms it is difficult to formulate an answer and whether or not the question should include any equality signs.

Is simply 2x + 5, nothing more, nothing less.

F- x - - band - was created in 2009.

5x+5 = 20

Subtract 5 from both sides:

5x = 15

Divide both sides by 5 to find the value of x:

x = 3
