Answer:

119

Step-by-step explanation:

Find 10% by dividing by 10, then halve it to get 5%. The answers are 14 and 7 accordingly.

Add them together to get 15%, which is now 21.

Take 21 off of 140 to get the answer, which is 119.

ALTERNATIVE METHOD - CALCULATOR

To solve the question using a calculator and with only one equation, multiply the number by 0.85 to find 85% of the number, and there's your answer.

SOMEONE HELPPP THANKYOUU
Eduardwww [97]

Answer:

5(8 - 2t) = 2 + 16(4 + t)

open the brackets;

use 5 to mulitiply (8 - 2t) = 40 - 10t

use 16 to mulitiply (4 + t) = 64 + 16t

then we have 40 - 10t = 2 + 64 + 16t

collect like terms

40 - 2 - 64 = 16t + 10t

-26 = 26t

divide both sides by 26

t = -1
