Answer:
x = 40
Step-by-step explanation:
If you add the total of 3 angles in a STRAIGHT line, you have to get 180 in total.
So, x = 180 - ( 80 + 60 )
= 180 - 140
= 40
Answer:
x=4
Step-by-step explanation:
3(x+2) = 2(x+5)
Distribute
3x+6 = 2x+10
Subtract 2x from each side
3x-2x+6 = 2x-2x+10
x +6 = 10
Subtract 6 from each side
x+6-6 = 10-6
x = 4
Answer:
337
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Total number of boxes bought = 8
Total amount spent = 2,696
So, we can calculate the cost of 1 box by using following formula
Cost of 1 box = Total amount spent ÷ Total number of boxes bought
By putting the value, we get
Cost of 1 box = 2,696 ÷ 8
= 337
Hence, the cost of 1 box is 337.
$4.30
Do ten times $3.57 and subtract it from $40
