Answer:

<em>Conner's work is correct</em>

Step-by-step explanation:

<u>Operations With Exponents</u>

We need to use the rule to find the product of two or more exponential expressions:

$x^m\cdot x^n\cdot x^p = x^{m+n+p}$

We need to multiply:

$(3^5 6^8)(3^9 6^{10})$

Base 3 is treated independently from base 6, so we have two groups of operations:

$(3^5 6^8)(3^9 6^{10})=3^{5+9} 6^{8+10}$

Adding the exponents:

$(3^5 6^8)(3^9 6^{10})=3^{14} 6^{18}$

Thus, Conner's work is correct

At a particular restaurant each mozzarella stick has 90 cal in each pizza roll has 80 cal. A combination meal with the mozzarell

serious [3.7K]

Answer:

The meal consist 11 mozzarella sticks and 6 pizza rolls.

Step-by-step explanation:

We are given the following in the question:

Calories in mozzarella stick = 90

Calories in pizza roll = 80

Let x be the number of a mozzarella stick and y be the number of pizza rolls.

Total calories in meal = 1470

Thus, we can write the equation:

$90x + 80y = 1470$

There are five more mozzarella sticks than pizza roll.

Thus, we can write the equation:

$x = y + 5\\x-y = 5$

Solving the two equations, we get,

$90x+80y+80x-80y = 1470 + 400\\170x = 1870\\x = 11\\y = 11-5 = 6$

Thus, the meal consist 11 mozzarella sticks and 6 pizza rolls.
