Step-by-step explanation:
1. put into heavy fraction
7⅓ is 22/3 (7*3 +1)
2 2/9 is 20/9 (2*9 then add 2)
so 22/3 divide by 20/9
Use keep change flip
Flip 22/3 to 3/22
change divide into multiply symbol
2nd fraction is the same
so
3/22*20/9 is 60/198
60/188 simplify to 15/47
Hope this helps !!!!
Have a nice day :)
To find total number of girls multiply total students by the fraction of girls:
360 x 4/9 = 360 x 4 = 1440/9 = 160 total girls.
If 3/5 are below the age of ten, that means 2/5 are above the age of ten.
Multiply the total number of girls by 2/5:
160 x 2/5 = 320/5 = 64
There are 64 girls above the age of ten.
First, you distribute the 3 into the brackets,
<span>3(x - 2) + 5x
=</span><span>3(x) + 3(-2) + 5x
=3x - 6 + 5x
Adding the like terms, 3x and 5x, gives you
=8x - 6</span>
Answer:
D
Step-by-step explanation:
This is called "implication". So if A (is true), then B MUST be true. If B is false, the implication is false. In all other cases, the implication is true. Suppose A is false, then it doesn't matter what B is, the implication is true, since we don't care what B is.
It's a bit confusing I suppose. Below is a truth table using P and Q in stead of A and B.
Answer:
Step-by-step explanation:
Let x and y represent the cost of a cupcake and cookie respectively.
Given that;
Five cupcakes and two cookies cost $19.75.
Two cupcakes and four cookies cost $17.50.
Let's solve the simultaneous equation by elimination;
Multiply equation 1 by 2;
Subtract equation 2 from equation 3;
divide both sides by 8
Since we have the value of x, let substitute into equation 1 to get y;
therefore , the cost of cupcakes and cookies are;
