for a field trip the school bought 47 sandwiches for $4.60 each and 39 bags of chips for $1.25 each. How much did the school spend in all?

To get to your final sum you will have to calculate the sum of both items: the sandwiches and the chips. Then you will get the total sum of all what they spend.

Step 1:

Sum of  one sandwich= 4.60 dollar

sum of 47 sandwiches= 47×4.60 =216.2dollars

Step 2:

Sum of one chip=1.25 dollar

sum of 39 bags of chips=39×1.25= 48.75dollars

step 3: sum up the sum of sandwiches and that of the chips

216.2 + 48.75 =264.95dollars

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

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
