Answer:
x=13
Step-by-step explanation:
all triangles add up to 180 so set equal to 180
77+90+x=180
solve for x
x=13
Alright, so since you can't multiply 2/9 into 1 super easily, we could divide it by 2 and multiply it by 9 then to get 1, so that's what we'll do. Since 3+3/5 is
15/5+3/5=18/5 (since 5 goes into 15 3 times), we can divide that by 2 to get 18/2/5=9/5. Multiplying that by 9, we get 9*9/5=81/5=the amount of minutes it would take to iron 1 shirt. Since 5 goes into 80 16 times, we can write 81/5 as 80/5+1/5=16+1/5. In addition, we need to find how long it would take to iron 5 shirts, and to do that we can multiply 1 shirt's time by 5, getting
81*5/5=405/5=81 minutes since 5 goes into 405 81 times.
Answer:
$91
Step-by-step explanation:
They bought 7 backpacks each costing $8. Multiply them together to get $56. They filled each with $5 worth of supplies. 7 * 5 = 35. $56 + $35 = $91
10/16
5 x 2 = 10
8 x 2 = 16
there for the answer is 10 / 16
