<h3>What is the greatest common factor for 60 and 45 ?</h3>
<em>The greatest common factor (GCF) is also known as greatest common divisor (GCD).</em>
<em>First we have to find the prime factorization of 60</em>
60 = 2² × 3 × 5
<em>Then we have to find the prime factorization of 45</em>
45 = 3² × 5
<em>Now we have to multiply the common factors to both numbers with a lower exponent</em>
GCF = 3 × 5 = 15
Answer : GCF(60,45) = 15
Hope this helps!
4^5 * 4^3
This can also be written as:
(4*4*4*4*4)(4*4*4)
Solve brackets first.
(1024)(64)
Multiply.
65536.

Answer:
96 points
Step-by-step explanation:
Ratio problems can be solved like this:
Let x equal an unknown value.
Now, we can write an equation.
7x + 10x +12x = 232
We want to find 12x, so we have to find x first. We can simplify our equation to:
29x = 232
Now, divide both sides by 29.
x=8
We then solve for 12x by multiplying 8 and 12, and get 96 points.
Answer:
The required expression is y = 1.4 - 0.05x
Step-by-step explanation:
Consider the provided information.
Food mix A contains 2% fat and food mix B contains 7% fat.
Let x kilograms of food A are used, in a 20-kilogram mixture.
Thus, 20 - x kilograms of food B are used, in a 20-kilogram mixture.
Now It is given that A contains 2% fat and food mix B contains 7% fat.
2% and 7% can be written as 0.02 and 0.07 respectively. Let represent the total fat with y.
Thus, the required expression is:
y = 2% (x) + 7% (20 - x)
y = 0.02 (x) + 0.07 (20 - x)
y = 0.02x + 1.4 - 0.07x
y = 1.4 - 0.05x
Hence, the required expression is y = 1.4 - 0.05x
