The Jones family traveled 314 miles each day until they reached their destination, which is 1,256 miles away from their starting
Flura [38]
It took them 4 days until they arrived at their destination.

314 × 4 = 1256

Another way of solving it:

Total amount of miles ÷ miles per day = The amount of days.

1256 ÷ 314 = 4

Before going to school, Eudora ran from her home to a secret laboratory at an average speed of 12 km. Since she was running late
Brrunno [24]

Answer:

Eudora spent 0.5 hours in running and 1.5 hours flying using her jet-pack.

Step-by-step explanation:

Let x represent time spent in running.

We have been given that the entire trip took 2 hours, so time spent in flying the jet-packs would be 2-x.

We know that distance is equal to speed times time.

\text{Distance}=\text{Speed}\times\text{Time}

Eudora ran from her home to a secret laboratory at an average speed of 12 km, so distance traveled by running would be 12x.

Eudora took one of her jet-packs and flew to her school at an average speed of 76 km, so distance covered by jet-packs would be 76(2-x).

We are told that Eudora traveled a total distance of 120 km. We can represent this information in an equation as:

12x+76(2-x)=120

12x+152-76x=120

Combine like terms:

-64x+152=120

-64x+152-152=120-152

-64x=-32

Divide both sides by -64:

\frac{-64x}{-64}=\frac{-32}{-64}

x=0.5

Therefore, Eudora spent 0.5 hours in running.

Upon substituting x=0.5 in expression for time spent in flying jet-packs, we will get:

2-x\Rightarrow 2-0.5=1.5

Therefore, Eudora spent 1.5 hours flying using her jet-pack.

PLS HELP !!! I need this question done quick
NeX [460]

Answer:

a. 17  b. 51

Step-by-step explanation:

Follow Order of Operations (PEMDAS):

Parentheses, Exponents, Multiplication/Division, Addition/Subtraction

a.  9 + 4² - (4-2) • 4

9 + 4² - (4-2) • 4 –––Start with (4-2) = 2 (parentheses)

9 + 4² - 2 • 4 ––– 4² (exponents)

9 + 16 - 2 • 4 ––– 2 • 4 (multiplication)

9 + 16 - 8 ––– 9 + 16 (addition)

25 - 8 ––– 25 - 8 (subtraction)

17

b. 15 - 4 + 2(7-3) • 5

15 - 4 + 2(7-3) • 5 ––– Start with 2(7-3)

~ Note: this can be done using distributive property (2•7 - 2•3) OR solving the parentheses first and then multiplying 2(4). Both get 8 and same end result.

15 - 4 + 8 • 5 ––– 8 • 5 (multiplication)

15 - 4 + 40 ––– 15 - 4 (subtraction) *Note: Subtraction and addition are interchangeable in the order because you do it left to right*

11 + 40 ––– 11 + 40 (addition)
