Answer:you need to write them as fractions so 36.22/x=2374/1 then cross multiply to get 2374x/2374=36.22 /2374
Then cancel out 2374 since the numerator and denominator are the same which means it’s equal to 1x and you get x=36.22/2374

Answer:
6+n/8=2
Step-by-step explanation:
* More Than = (+) or in some cases (>)
* Quotient of a (#) = Any letter that represents a number, so in this case "n", because we do not know that number yet. We divide this with "8" because it says "and 8".
* Equal = <---
Answer:
Step-by-step explanation:
l = length
b = breadth
We know the length is twice the breadth, therefore l = 2b
We also know that the perimeter p = 60m and can also be expressed as a sum of its sides where p = l + l + b + b = 60 which simplified is:
60 = 2l + 2b
Now we have 2 variables, but thankfully we were given a ratio (l = 2b) relating the two. Substituting 2b in for l gives us:
60 = 2(2b) + 2b = 4b + 2b = 6b
60 = 6b
b = 10 m
Now that we know the breadth we can find the length:
l = 2b → l = 2(10) = 20 → l = 20 m
With a breadth of 10 m and a length of 20 m
Answer:
x=2 and y=-1. The steps--
Step-by-step explanation:
<em>FIRST STEP: </em>SUBSTITUTE -4y with the definition in y=2x-5. This makes the first equation -3x-4(2x-5)=-2
<em>SECOND STEP: </em>DISTRIBUTE -4 throughout the parenthesis, making the equation -3x-8x+20=-2.
<em>LAST STEP: </em>SOLVE by combining like terms, -3x-8x, to make -11x, and subtracting 20 from each side, to make -11x=-22. Then divide both sides by -11, making x=2. From there, you solve that y=2(2)-5, solving that y=4-5, y=-1.
Therefore, x=2 and y=-1
