Mathematics
1 answer:
Art [367]2 years ago
3 0

Answer:

no solution

Step-by-step explanation:

4(9x + 4) = 36x - 7 ← distribute parenthesis on left by 4

36x + 16 = 36x - 7  ( subtract 16 from both sides )

36x = 36x - 23 ( subtract 36x from both sides )

0 = - 23 ← False statement

This indicates the equation has no solution

A formula is expressed as D= a(2+kt). Express k in terms of D,a, and t.
Yuri [45]
This is just rearranging terms, it gets kind of ugly though. Start by dividing both sides by a to get D/a=2+kt, next move the 2 over to the left to get (D/a)-2=kt, finally divide the whole expression by t to get ((D/a)-2)/t=k

sergeinik [125]

Isaiah will mow 9 lawns in 3 hours at the given rate.

Step-by-step explanation:

Given,

Lawns mowed in 25 hours = 75 lawns

We will find unit rate in terms of lawns;

75 lawns = 25 hours

1 lawn = \frac{25}{75}=\frac{1}{3}\ hour

9 lawns = \frac{1}{3}*9

9 lawns = 3 hours

Isaiah will mow 9 lawns in 3 hours at the given rate.

A square and a rectangle have the same perimeter is the length of the side of the square is 4X minusone the score of the rectang
Assoli18 [71]

Square Perimeter = 4(4x-1)

Rectangle Perimeter = 2(2x+1) + 2(x+2)

Square Perimeter = Rectangle Perimeter

4(4x-1) = 2(2x+1) + 2(x+2)

16x - 4 = 4x + 2 + 2x + 4

16x - 4 = 6x + 6

-6x +4 -6x +4

10x = 10

x = 1
