For each expression, write an equivalent expression that only uses addition a. 20 - 9 + 8 -7 b. 4x - 7y - 5z + 6 c. -3x - 8y - 4
Genrish500 [490]

Answer:

a. =11+ 1

b. =4x+ (-7y) + (-5z) +6

c. (-3x) + (-8y) +(-4)+(-8/7z)

Step-by-step explanation:

a. 20 - 9 + 8 -7

=11+ 1  ( this is obtained by solving)

b. 4x - 7y - 5z + 6

=4x+ (-7y) + (-5z) +6

We multiply the negative sign with the positive sign to get a minus so the answer remains the same and the expression is written as an addition sum.

c. -3x - 8y - 4 - 8/7z

-[ 3x+8y+4+8/7z]

or

(-3x) + (-8y) +(-4) +(-8/7z)

The minus sign is taken as common leaving the expression with the plus only.

It can be written in the same manner as above, adding the negative terms so that the expression is written as a sum.

HELP DUE IN 15 MINS!<br><br> x=??
ad-work [718]

Answer:

Step-by-step explanation:

Remark

The angle formed by the intersection of a tangent to a circle and an intersecting secant is 1/2 (Arc PS - arc PR)

PS = 208

PR = 74

Solution

x = 1/2 (208 - 74)

x = 1/2 (134)

x = 67

Plot the line for the equation on the graph. y−4=−1/4(x−5)
icang [17]
You just need two points to graph a line.

When x = 1 

y - 4 = -1/4(1 - 5)
y - 4 = -1/4(-4)
y - 4 = 4/4
y - 4 = 1
y = 5

So, we have our first point, (1,5)

When x = 2

y - 4 = -1/4(2 - 5)
y - 4 = -1/4(-3)
y - 4 = 3/4
y = 4 3/4

Now we have the point (2, 4 3/4)

Now just run a line through the two points and you're done!

Solve the equation: n + 32 = 60.
Digiron [165]
N + 32 = 60

First, so basically, we are trying to find a number that can add up with 32 to equal 60. The easiest route to solve this is to simply take 32 and subtract it from 60.
n = 60 - 32

Second, once we subtract, we will be given the answer and know what 'n' is. Subtract 60 - 32 to get your answer. 60 - 32 = 28
n = 28

Third, know that we know that the answer to 'n' is 28, we can check it by adding 28 + 32. Your answer should be 60, and 28 is the correct answer.

Answer: \fbox {n = 28}
