How does " 7 less than three-fifths of a is b" look

1 answer:

3 0

Let's do it step by step:
"three-fifths of a" would be 3/5 multiplied by a, as that is how you find fractions of numbers, so we can write that as (3/5)a
"7 less" means we have to subtract 7 from (3/5)a, so we get (3/5)a - 7
Now all we need to do is make it equal to B, so your final answer is
(3/5)a - 7 = b

I hope this helps! I put the 3/5 in brackets just so you didn't mistake it as 3/(5a) :)

2. Three points of a parallelogram are (4, 3), (-4, 3), and (2, 3). Find the coordinates of the 4th point to complete the parall

antiseptic1488 [7]

Parallelograms have equal and parallel opposite sides

<em>The coordinates of the 4th point is (-2,3)</em>

Let the parallelogram be ABCD, such that:

$A = (4,3)$

$B =(-4,3)$

$C = (2,3)$

A and B have the same y-coordinates, while their x-coordinates are additive inverse

This means that:

The y-coordinates of point C and point D will be the same, while their x-coordinates will be additive inverse.

<u>For point C</u>

We have:

$x = 2$

$y = 3$

<u>For point D</u>

The coordinates would be:

$x =- 2$

$y = 3$

Hence, the coordinates of D is (-2,3)

Answer:

$36

Step-by-step explanation:

ok so first you want to find out how much she makes per hour and to do that you would take $27 / 3hrs = $9. So now we know that Kayla makes $9 per hour. If she babysits for 4 hours you would then do $9 x 4hr = $36.

Simplify (34)−1.

elena55 [62]

The simplified form of the expression; (3/4)-¹ as given in the task content is; 4/3.

<h3>What is the simplified form of the expression as given in the task content?</h3>

It follows from the task content that the expression in discuss can be simplified as follows by the laws of indices;

(3/4)-¹

Hence, due to negative exponent, the result is;

= 1 ÷ (3/4)¹

= 1 × (4/3)

= 4/3.
