Example
3 ÷ 93
first, how many times does three go into nine
then,subtract that from nine
after that how many times does three go into three
Step-by-step explanation:
Option 1 and 4 are correct for sure
There are 187 nickels and 66 dimes in the jar.
Step-by-step explanation:
Given,
Total coins = 253
Value of coins = $15.95 = 15.95*100 = 1595 cents
Value of each nickel = 5 cents
Value of each dime = 10 cents
According to given statement;
x+y=253 Eqn 1
5x+10y=1595 Eqn 2
Multiplying Eqn 1 by 5
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 5
Putting y=66 in Eqn 1
There are 187 nickels and 66 dimes in the jar.

Answer:
x=7,3
Step-by-step explanation:
x^2-8x+14=2x-7
Add 8x to both sides.
x^2+14=10x-7
Add 7 to both sides.
x^2+21=10x
x^2+7*3=10x
(x*7)+(x*3)=10x
x=7,3
Hope this helps plz hit the crown :D
10x⁴ and 6w³
1) We see no the same letters in both expressions, so we will need to include all letters in the final answer. x⁴w³
2) number part
10 = 2*5
6=3*2
We need 2*3*5=30 (we need 2 only one times, because we have 2 only one time in each of the numbers).
3)The least common multiple
2*3*5x⁴w³ = 30x⁴w³
Answer is 30x⁴w³.
