Step-by-step explanation:

you could think that 22% is close to 25% , so one forth of it, 1/4

78 percent is close to 80

1/4 of 80 is 20

actually 78*22/100=17.16

FP!!!!!!!!!!!!!!!!!!! if ur up<br><br> ( 10 x 8 ) + 150
taurus [48]

Answer:

220

Step-by-step explanation:

<u>first we have by Bracket of BODMAS rule then we have to multiply 10 *8 = 80</u>

<u>first we have by Bracket of BODMAS rule then we have to multiply 10 *8 = 80then we have to open bracket 80 +150</u>

<u>first we have by Bracket of BODMAS rule then we have to multiply 10 *8 = 80then we have to open bracket 80 +150 = 220</u>

<u> (10*8) +15</u>

<u>Solution</u>

<u>Solution= (80) +150</u>

<u>Solution= (80) +150= 80+150</u>

<u>Solution= (80) +150= 80+150=. 220</u>

<u>Solution= (80) +150= 80+150=. 220 </u>

The graph of a line passes through the points (0, -2) and (6, 0). What is the equation of the line? 1. y = -2x + 6
densk [106]

Answer:

The Answer is: y = 1/3x - 2

Step-by-step explanation:

Giving points: (0, -2) and (6, 0).

First find the slope:

m = y - y1/(x - x1)

m = -2 - 0/0 - 6

m = -2/-6 = 1/3

Use the point slope form of the equation with point (0, -2) and solve for y:

y - y1 = m(x - x1)

y - (-2) = 1/3(x - 0)

y + 2 = 1/3x

y = 1/3x - 2

Hope this helps! Have an Awesome day!! :-)
