Jack skateboarded for 60 minutes on Saturday, 35 minutes each on Monday and Tuesday, and 40 minutes each on Wednesday and
Sunday. Write an expression that shows the total amount of time
the spent skateboarding that week. Then evaluate the expression.

tangent

step-by-step explanation:

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14

triangle eg 7.5 × cos "a" or 7.5 × sin "b" or 6 tan"a"
