notes:

c= Colin

s=Sara

g=Gordon

c=g+36 (1)

c : g

5 : 1

c/g=5

c=g*5 (2)

=> from statement (1) => g*5=g+36

5g-g=36

4g=36

g=36/4=9 g=9 sweets

=> from statement (2)=>c=5*9=45 c=45 sweets

s : g

2 : 1

=>s/g=2/1

=> s=2g

s=2*9 s=18 sweets

sum=c+s+g

sum=45+18+9=72 sweets

What’s the hypotenuse?
Karolina [17]

Answer:

c = 10 feet

Step-by-step explanation:

Use the Pythagorean theorem:  a^2 + b^2 = c^2

<u>Step 1:  Plug in the information</u>

(6)^2 + (8)^2 = c^2

36 + 64 = c^2

100 = c^2

sqrt(100) = sqrt(c^2)

<em>10 = c</em>

<em />

Answer: c = 10 feet

4a+6b=10<br> 2a-4b=12<br><br> what does 12a =?
Usimov [2.4K]
If you have at least as many equations as your have unknown variables, the 'system' is solvable (unless the equations are copies of eachother).

In this case, isolate one letter and plug it in the other. I'm going for the 2a in the bottom one (it doesn't matter)

2a - 4b = 12 => (divide by two and move the b's to the other side)

a = 6 + 2b. (plug this one into the top equation)

4(6+2b) + 6b = 10 => 24+8b+6b = 10 => 24 + 14b = 10 => 14b = -14 => b=-1

a = 6 + -2 = 4.

So a=4 and b=-1.

2x+4y=24<br> -12x+8y=-16
EleoNora [17]
Dividing the first equation by 2
X + 2y = 12
Dividing the equation 2 by 4
-3x + 2y = -4
subtracting both equations
4x = 16
X = 4
Also 4 + 2y = 12
2y = 8
Y = 4
