Answer:

Yvette cleared 10 large driveways

Step-by-step explanation:

small driveway = x

big driveway = y

x+y = 25

15x + 25y = 475

y = 25-x

15x + 25(25-x) = 475

-10x + 625 = 475

10x = 150

x= 15

15 + y = 25

y =10

10 large driveways, 1 5 small driveways

One and one over seventh times three fifths
andreyandreev [35.5K]

Answer:

24/35

Step-by-step explanation:

1) Convert your mixed number (1 and 1/7) to an improper fraction by multiplying your whole number (1) and your denominator (7) which gives you 7. Then add your numerator (1) to that which gets you 8. Then take the original denominator (7) and turn it into improper where your new numerator is 8 and your denominator stays 7. (If that doesn't make much sense then you can look up how to change mixed numbers into improper fractions.)

2) Multiply your numbers straight across.

8/7 * 3/5

8*3= 24

7*5= 35

24/35  you can't simplify this, so 24/35 is your answer

(2*2)^2-(3+(2*2)/(6-4) EXPLAINED PLEASE
Eva8 [605]

PEMDAS is an acronym that refers to the sequence of operations to be employed when solving equations with multiple operations. The solution of the given expression (2×2)² - [3+(2×2)]/(6-4) is 14.

<h3>What is PEMDAS?</h3>

PEMDAS is an acronym that refers to the sequence of operations to be employed when solving equations with multiple operations. PEMDAS is an acronym that stands for P-Parenthesis, E-Exponents, M-Multiplication, D-Division, A-Addition, and S-Subtraction.

As per the rule of PEMDAS, the given expression can be simplified as shown below.

(2×2)² - [3+(2×2)]/(6-4)

Step 1: Solving Parenthesis,

= 4² - (3+4) / (2)

= 4² - 4/2

Step 2: Solving exponents,

= 16 - 4/2

Step 3: Solving Divisions,

= 16 - 2

Step 4: Solving Subtraction,

= 14

Hence, the solution of the given expression (2×2)² - [3+(2×2)]/(6-4) is 14.
