The product is 7/2. Hope that helps
Answer:
DIVIDING 9 AND 5 = 23.8
9/5 FRACTION = 0.04
Step-by-step explanation:
If 9/5 means 9 divided by 5
FLIP THE EQUATION
9/5C + 32 = 75
9/5C + 32 - 32 = 75 -32
9/5C = 43
9/5 = 1.8
1.8C = 43
1.8C/1.8 = 4
If 9/5 means 9/5ths fraction
FLIP THE EQUATION
9/5C + 32 = 75
9/5C + 32 - 32 = 75 -32
9/5C = 43
9/5C / 9/5 = 43 / 9/5
C = 0.04
Hope this helps i thought 9/5 was 9 divide by 5. If it was 9/5 as a fraction i also made that equation too.
OK first convert one of the equations into Y=MX+b form
Y-2x = 3
Add 2X
Y = 2x +3
Now substitute this equation in the other one.
So it would be
3X - 2Y = 5
3X-2(2x+3) = 5
Now solve for y
3X - 4X - 6 = 5
-1X - 6 = 5
Add 6
-1X = 11
X = -11
Now substitute this into one of the equations
Y - 2X = 3
Y -2(-11) = 3
Y +22 = 3
y = 3-22
y = -19
So for number 3, so for every 15 he earns, he saves 6 so
15:6=5:2
then he earns 75 and saves x
5 times what=75
5 times 15=75
2 times 15=30
so the ration is 75:30
he saved $30
then
write a real life proportion
so rob has a pattern to make,
for every 5 blue tiles, he puts down, he must put down 7 green tiles,
he needs to fill a sqare area that is 12 feet in legnth and width
each tile is 1 foot
how many blue tiles will he need
so 5+7=12
area=12 times 12
area=144
so the number of tiles is 144
so blue=5/12
so 144 times 5/12=60 blue tiles
