Answer:
10/21=30/63
4/9=28/63
Step-by-step explanation:
Find the lcm (least common multiple) of 21 an 9, which is 63. Then divide 21 and 9 separately by 63. The multiply that number by the numerator.
Answer:
its 6.75
Step-by-step explanation:
3/10 = 0.3
2/5 = 0.4
0.3 / 0.4 = 0.75
0.75 x 9 = 6.75
hope i helped
Answer:
y=11
x=8
Step-by-step explanation:
This is Elimination
2x+2y=38
Subtract 2x on both sides 2y=-2x+38
Then Multiply 2(y=x+3) which equals 2y=2x+6
Solve by Elimination
2y=-2x+38
2y=2x+6
add the y's and since the x's are different those cancel out, then add 38 and 6.
then you do the equation 4y=44
divide both by 4
y=11
then you do 11=x+3
subtract 3 on both sides
x=8
and there you go
I hope this is how you wanted it solved
6xy+32
You multiply 8x by each number and get
24/4xy+32 You can simplify the 24/4 to get six. so your answer is
6xy+32
