STEP 1
calculate total ounces
= 16 oz/lb * 3 lbs
= 48 ounces
STEP 2
calculate number of bolts; divide total weight (48 ounces) by ounces per bolt
x= number of bolts purchased
x= 48 ounces ÷ 1/15 oz per bolt
x= 48 ÷ 1/15
to divide by fraction; multiply by reciprocal of 1/15
x= 48 * 15/1
x= 720 bolts
ANSWER: He purchased 720 bolts
Hope this helps! :)
Answer:
x=-2
Step-by-step explanation:
2x+1=(-3)
-1 on both sides
2x=-4
÷2 on both sides
x=-2

Answer:
6.53
Step-by-step explanation:
cos(theta)= adjacent/hypotenuse
cos(40)= 5/h
H= 5/cos(40)
=6.527
Rounded to the nearest hundredth will be 6.53
But D In The Plot Then divide
Answer: x=9
Explanation: All 3 angles of a triangle add up to 180, so basically the equation is (3x-5)+(7x+5)+90=180.
Then you add your like terms, so 3x+ 7x=10x and -5+5=0, which cancels out. Now we have 10x+90=180, we subtract the 90 from 180 to see what 10x is equal to and we get 90. So 10x=90. We divide 10 from 90 and we get the value of X, which is 9.
