Answer:
2
Step-by-step explanation:
There are four giraffes that equal 32. That means the four of them equal 32, and since they are all giraffes, they are the same amount.
32/4 = 8
Girrafe = 8
Two tigers times a giraffe equals 32. We already know that a girrafe equals 8.
32/8 = 4.
Therefore the two tigers equal 4. Since there are two tigers, and they equal 4, each tiger equals 2.
Now we know girrafes equal 8, and tigers equal 2.
A girrafe - A tiger x 3 = 2
PEMDAS says that you multiply first. So 2 x 3 equals 6. Take away 6 from 8 and you get 2.
First of all, you should know/notice that
You should also know how negative exponents work:
So, if you wanted
the answer would be x=3, but since you want 125 to be at the denominator, the answer is x=-3:
2x-3y=7
-3y = -2x+7
y= 2x/3-7/3
slope of 2/3 (rise 2, run 3)
y-intercept of -7/3
Would be a positive line, starting low on left and rising towards right
Just make the equations equal to each other. -0.5x+5=3x-2. Solve for x and find that it is 2, via simple algebra. Since you know x is 2, sub it in in either equation to find y. y should be 4. So the point that fits both equation is (2,4). This shows that the two graphs of these lines will intersect at this exact point.
If you were to graph these two lines, you ould see that the point of intersection is at (2,4) like we solved for.
