Use the given set to determine the solution for each equation. 7t + 26 = 61 {3, 5, 7, 9}

t=

5

Step-by-step explanation:

you have to subtract 26 on both sides.

so then the equation turns into 7t = 35

then you dive both sides by 7, leaving the equation as t=5

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
