Answer:
1) 
2) 
Step-by-step explanation:
You can convert he mixed numbers to improper fractions:
1. Multiply the whole number part by the denominator of the fraction.
2. Add the product obtained to the numerator.
3. The denominator does not change.
Then:
Observe that, in each subtraction, the denominators are equal, then you can rewrite the denominator and subtract the numerators:
Divide 15 by 4. The quotient will be 3 and the remainder 3.
Then:
11c-8
11c is the product of both 11 and c, and the 8 less than the product is shown with -8
Answer:
The clown has 363 yellow balloons
Step-by-step explanation:
The clown has 165 red balloons.
Let us say the clown has x yellow balloons
The question tells us that this value is 198 balloons less than the yellow ones.
This means that if we add 198 to the number of red balloons we should get x - the number of yellow ones.
x = 165 +198 = 363 balloons
Therefore, the clown has 363 yellow balloons
The answer is true, and let me explain this to you like this:
<span>F(x) = 4x - 6
when x = 1, F(x) = 4 * 1 - 6 = -2
when x = 2, F(x) = 4 * 2 - 6 = 2
when x = 3, F(x) = 4 * 3 - 6 = 6
when x = 4, F(x) = 4 * 4 - 6 = 10
</span><span>second row is: -2, 2, 6, 10
</span><span>differences are: 2 - (-2) = 4; 6 - 2 = 4; 10 - 6 = 4
</span>So, the <span>second row is in arithmetic progression.
Hope this is what you were looking for</span>
