3 + 7 > 10 - 2
10 > 8...correct
Answer:
25.375 ounces
Step-by-step explanation:
To find the weight of the largest shirt size, we need to find the value that is 1 3/4 times as much as the smallest shirt size. To do this, we need to multiply the two numbers (14.5 x 1 3/4). In order to make this process easier, we can convert 1 3/4 into a decimal, which would be 1.75. After that, we just multiply; 14.5 x 1.75 = 25.375. Your answer is 25.375 ounces.
Answer:
x=133 y=-25
Step-by-step explanation:
I'll do both ways for you. So let's start with Substitution:
With the sub method, you have to set both equations equal to each other by setting them equal to the same variable. Since there is no coefficient in front of both x's in both equations, that variable will be easiest to solve for.
x + 2y = 83 & x + 5y = 8
Solve for x.
x = 83 - 2y & x = 8 - 5y
Once you have solved for x, set each equation equal to one another and solve for y now.
83 - 2y = 8 - 5y
Isolate all variables to one side:
83 = 8 - 3y
Now subtract the 8 to fully isolate the y variable:
75 = -3y
Divide by -3:
-25 = y Now that you have your first variable, plug it into one of the original equations and solve for x.
x + 2(-25) = 83
x - 50 = 83
x = 133
Now for the Elimination method. For this method you need to get rid of a variable by either subtracting/adding each equation together. Again, since you can subtract and x from both equations, you will be left with only the y variable to solve:
Put each equation on top of one another and subtract:
x + 2y = 83
- (x + 5y = 8)
The x's will cancel out:
(x - x) + (2y - 5y) = (83 - 8)
Simplify:
-3y = 75
Solve for y
y = -25
Then, plug y = -25 into one of the original equations:
x + 5(-25) = 8
Solve for x:
x - 125 = 8
x = 133
Hope this helps!
Divide 3/4 by 1/8 and you should get 6 hurdles.
There are no decimal points, and there are 2 numbers. Therefore, the first number will be a "10s" number, and the second will be a "1s" number.
