3x+1=10 solve each equation. check your soultion

-3+8n=-5

4h-6=22

➷ 3x + 1 = 10

Subtract 1 from both sides:

3x = 9

Divide both sides by 3:

x = 3

To check this, substitute this value back in:

3(3) + 1 = 10

b) -3 + 8n = -5

Add 3 to both sides:

8n = -2

Divide both sides by 8:

x = -0.25

To check, substitute it back in:

-3 + 8(-0.25) = -5

c) 4h - 6 = 22

Add 6 to both sides:

4h = 28

Divide both sides by 4:

h = 7

To check, substitute it back in:

4(7) - 6 = 22

➶ Good Luck (:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
