The estimate of 3630 is 4000. because the hundreds place is higher than 5, so you would go a number higher

You can round 396 to 400 and 71 to 70. then you just multiply them and get 28,000. :))

Given that R= 9x + 8y<br> Find y when x = 3 and R= 27

Amiraneli [1.4K]

Answer:

1/3 or 0.3 (recurring)

Step-by-step explanation:

Let's substitute our numbers into the equation.

27 = 9x + 24 I multipled 8 by 3 in order to get 24, because x equals 3.

Now take away 24 leaving 9x on its own.

3 = 9x

Divide 9 to separate it from x.

3/9 = x

Simplify the fraction.

1/3 = x

Factor completely 4xy − 7x + 20y − 35.

kati45 [8]

Answer:

A) $(x+5)(4y-7)$

Step-by-step explanation:

Given expression:

$4xy-7x+20y-35$

To factor the given expression completely.

Solution:

In order to factor the expression, we will factor in pairs.

$(4xy-7x)+(20y-35)$

We will factor the G.C.F of the terms in the pairs.

G.C.F. of $4xy$ and $7x$ can be given as:

$4xy=4.x.y$

$-7x=7.x$

Thus, G.C.F. = $x$

G.C.F. of $20y$ and $35$ can be given as:

$20y=2\times 2 \times 5.y$

$35=5\times 7$

Thus, G.C.F. = $5$

The expression after factoring the G.C.F. pairs is given as:

$x(4y-7)+5(4y-7)$

Taking G.C.F. of the whole expression as $(4y-7)$ is a common term.

$(x+5)(4y-7)$

The expression is completely factored.
