Answer:

340

Step-by-step explanation:

$730 - $50 = $680

$680 / 2 = 340

they both have an equal of 340 and then mike adds in 50 more so:

340 + 340 = 680 + mike's $50 = $730.

It takes Carl 45 minutes to drive to work using two roads. She drives 32 mph on a small road for 1/2 hour. Then she drives 56 mp

Ksivusya [100]

Answer:

The Total distance she travel fro work is 30 miles .

Step-by-step explanation:

Given as :

the total time taken to cover distance = 45 minutes

Let The total distance cover = D miles

The distance cover at the speed of 32 mph = $D_1$ miles

The time taken to cover $D_1$ miles distance = $\frac{1}{2}$ hour

Distance = Speed × Time

∴ $D_1$ = 32 mph × $\frac{1}{2}$ h

or, $D_1$ = 16 miles

Again ,

The distance cover at the speed of 56 mph = $D_2$ miles

The time taken to cover $D_2$ miles distance = $\frac{1}{4}$ hour

∴ $D_2$ = 56 mph × $\frac{1}{4}$ h

or, $D_2$ = 14 miles

So , The total distance she travel for work = $D_1$ + $D_2$

Or, The total distance she travel for work = 16 miles + 14 miles = 30 miles

Hence The Total distance she travel fro work is 30 miles . Answer

The cost of 5 squash and 2 zucchini is $1.32. Three squash and 1 zucchini cost $0.75. Find the cost of each vegetable.

jonny [76]

Answer:

The cost of 1 squash = $0. 18

The coat if 1 zucchini = $ 0.21

Step-by-step explanation:

Here,Let us assume the cost of 1 squash = $ m

Cost of 1 zucchini = $ n

Now, the cost of 5 squash = 5 x ( cost of 1 squash) = 5 x ($ m) = 5 m

Now, the cost of 2 zucchini = 2 x ( cost of 1 zucchini) = 2 x ($ n) = 2 n

So, the total cost of 5 squash and 2 zucchini = Cost of (5 squash + 2 zucchini)

⇒ $ 1. 32 = 5 m + 2 n ........ (1)

Similarly,

The cost of 3 squash = 3 x ( cost of 1 squash) = 3 x ($ m) = 3 m

And, the cost of 1 zucchini = $ n

So, the total cost of 3 squash and 1 zucchini = Cost of (3 squash + 1 zucchini)

⇒ $ 0. 75 = 3 m + n ........ (2)

or, n = 0.75 - 3 m

Substitute this value in (1) , we get

1. 32 = 5 m + 2 n ⇒ 1.32 = 5 m + 2 (0.75 - 3 m)

or, 1. 32 = 5 m + 2(0.75) - 2(3 m)

or, 1 . 32 = 5 m + 1.5 - 6m

⇒ m = 1. 5 - 1. 32 = 0.18

or, m = 0. 18

So, the cost of 1 squash = $0. 18

And,the cost of 1 zucchini = n = 0.75 - 3 m = 0.75 - 3 (0.18) = 0.21

or, the cost if 1 zucchini = $ 0.21
