Answer:
480 bread rolls
Step-by-step explanation:
For 8 muffins, 6 bread rolls are sold.
This implies for every muffin, bread rolls are sold.
Hence for 640 muffins, they sold 640 ×
= 480 bread rolls.
Multiplicative inverse makes the numver 1 so it multiplies by 1 which cancles the number
examle
1/3x=10
to make 1/3 into 1
we multiplyu it by its mutlipcative invers which is 3/1
1/3 times 3/1=3/3=1
1/3x times 3/1=3/1 times 10
1x=30
additive inverse makes the number 0 to cancel it out
so example
x+3=10
add the inverse of 3 to make it 0
inverse of 3 is -3
3+-3=0
so x+3-3=10-3
x+0=7
x=7
Answer:
18
Step-by-step explanation:
90/5=18
(-6+k)/2=-9
Step 1: Simplify both sides of the equation.
(−6+k)/2=−9, 1/2k-3=−9
Step 2: Add 3 to both sides.
1/2k=-6
Step 3: Multiply both sides by 2.
k=12
