Scott needs to fill a 3-gallon pitcher with water, but it won't fit under the faucet. He fills a 1-quart container with water from the faucet and then pours the water into the pitcher. How many times will he need to fill the 1-quart container to fill the pitcher?How would you solve this?
Change the 0.2 into a fraction 2/10 Add the 2 to 2/10 to get 2 2/10, amixed number. To get a improper fraction, just multiply whole numberby denominator value plus the numerator value to get the improper fraction, which is 2*10+2/10= 22/10 The fraction for 0.625 would be would be 5/8, a proper fraction.

1) Solve using elimination Multiply the first equation by 2 and the second by 5 so you can figure out x 10x-6y=-18 10x-25y=20 Subtract the two equations 19y=-28 y=-2 Plug y into the equation and you get x=-3 (-3, -2) 2. C Just model the equation 3. B Again, it's all about turning the word problem into equations 4. D. Use substitution and plug the x into the first equation. 5. Multiply the whole first equation by 2. You can see that because 4*2=8 8x+10y=16 Hope this helps.
coinciedent equations are the same equations but indifferent forms example 2x+3y=2 is coincident with 4x+6=4 (multilied by 2)
so we have 4x+5y=8 next one was have 8x we see that 4 times 2=8 so we just double the numbers 5 times 2=10 8 times 2=16 answer is 8x+10y=16 missing numbers are 10 and 16
subsitution meathod absicalyy since you have x=y+2, then subsitue y+2 for x in the equaiton x+y=6 so (y+2)+y=6 there fro the answer is D
d=desmond g=george
d is 3 less than g d=-3+g d=g-3 combinded scores equals 187 d+g=187
the equations are d=g-3 and d+g=187 the answer is B
child tikcet is 2 dollars so number of children times cost per child=cost c times 2=cost=2c
adult tickets are same but differenc cost 6 times a=6a
so number of adults+number of kids=total number of people c+a=38
cost of adults+cost of kids=total cost 2c+6a=148
the equations are c+a=38 and 2c+6a=148 the answer is A
the solution is in the form (x,y) so solv for x and y 5x-3y=-9 2x-5y=4 multily the first equation by -2 and the second equaiton by 5
-10x+6y=18 10x-25y=20 add them together
-10x+6y=18 10x-25y=20 + 0x-19y=38 -19y=38 divide both sides by -19 y=-2 subsitute 5x-3y=-9 5x-3(-2)=-9 5x+6=-9 subtract 6 from both sides 5x=-15 dvide by 5 x=-3
x=-3 y=-2 solution is (-3,-2)
ANSWERS missing numbers are 10 and 16 D B A (-3,-2)

Suzanne bought 50 apples at the apple Orchard. She bought 4 times as many red apples. How many more red apples than green apples did Suzanne buy?
Answers
50 times 4 is 200 then you would subtract 50 from 200 and the answer is 150 more apples.
Since Suzanna bought 50 apples and bought 4 times as many red apples you would do 50x4 to get 200 then to find how many more you would subtract 50 from 200 to get 150
What can be added to -1 so it can be a positive 1?
Answers
so represent missing number with x x means unknown so x+-1=+1 adding a negative means subtraction x-1=1 you can do anything to an equation as long as you do it to both sides add 1 to both sides x+1-1=1+1 x+0=2 x=2
