Find the measure of the unlabeled angles 1) 129 degrees 2) 57 degrees 3) 51 degrees 4) 155 degrees

x=15 from the previous problem that I answered for you

Since (x+10) and that one blank angle are supplementary, they add up to 180 degrees.

x+10+y=180

15+10+y=180

25+y=180

y=155

Both unlabeled angles, due to the fact that they are vertical to each other, equal 155 degrees.

We also could figure this out by just taking 25 (the angle measurement of the labeled angles) and subtracting that from 180 without doing all of the fancy equation stuff.

Great question!! :)

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
