This will be solved by solving for x first. Firstly you multiply the top equation by 2 and the bottom by -3. This will change both equation to (top)-10x+6y=-54 and (bottom) 27x-6y=-57. Now when you add the factors the y-values cancel out leaving you with; 17x=-3. now you have to divide by 17 on both sides giving you x=-0.17647058823 (not the prettiest solution but you can round if you want to). After that pick an equation to solve for y (I'm picking the top); the equation will be 5(-0.17647058823)+3y=-27. multiply the negative decimal and 5 to get -0.88235294117 (again not the prettiest). Add that to both sides which will give you 3y=-26.1176470588. After this divide both sides by 3 which will give you y=-8.70588235294. Your answer is (-0.17647058823,-8.70588235294) You can divide to the second or third decimal if needed-----remember that as you round from left to right on a decimal if it's below five you leave it and if it's above 5 then round up 1. I hope this help :)
Answer:
160g
Step-by-step explanation:
150 gr/100 =3/2
to find the sugar needed you inverse the fraction
240(2/3) =160
OR you can do cross multiplication
150--------------100
240---------------x
(240*100) / 150 x
24000/150 = 160
Or you can think that 150 i 100 plus half of 100 (100 + 50) = 150
and 240 is 160 plus half of 160 (160+80)=240
Answer:
y-6 = 2 (x-5)
Step-by-step explanation:
point slope form
y-y1 = m(x-x1)
y-6 = 2 (x-5)
Given
1. 4 x 1/7
2. 12 x 2 5/6
procedure
1. The answer is 4 x 1/7 is less than 4
2. The answer is 12 x 2 5/6 is greater than 12
