Answer:

Answer:

-3x+5y=20

Step-by-step explanation:

Standard form is given by ax+by=c

where a , b and c are integers

here we have an equation

so we first multiply the complete equation by 5 to get rid of the fraction

Now subtract 3x from both side to get the required standard form

-3x+5y=20

Step-by-step explanation:

just move y to the side with x and move 4 to the other end

Tammy drove 871 miles in 13 hours.
Evgen [1.6K]

Answer:

Tammy takes 5 hours to drive 335 miles.

Step-by-step explanation:

Given that :-

  • Tammy drove 871 miles in 13 hours.

To find :-

How long would it take her to drive 335 miles ?

Solution :-

Let us assume that it take her to drive 335 miles in x hours.

To find x, we need to find it in ratios.

871 miles = 13 hours

335 miles = x hours

Using cross multiplication method

871 × x = 335 × 13

multiply to get

871 x = 4, 355

divide each side by 871

871 x / 871 = 4,355 / 871

x = 5

hence, Tammy takes 5 hours to drive 335 miles.

What is the value of s and the length of side BC if ABCD is a rhombus?
Natali5045456 [20]

Step 1

<u>Find the value of s</u>

we know that

In a Rhombus all sides are congruent

so

AB=BC=CD=DA

AB=9s+29\\CD=10s-16

equate AB and CD

9s+29=10s-16\\

Combine like term

10s-9s=29+16\\

s=45\ units

<u>The answer Part a) is</u>

the value of s is 45\ units

Step 2

<u>Find the value of side AB</u>

AB=9s+29

substitute the value of s

AB=9*45+29=434\ units

Remember that the sides are congruent

AB=BC=CD=DA

therefore

<u>the answer Part b) is</u>

The length of the side BC is 434\ units
