How do I solve (5x-7)(3x-8)?
nataly862011 [7]

(5x-7)(3x-8)

Expand using FOIL (multiply the firsts, then outers, then inners, then lasts):

Firsts: 5x * 3x = 15x²

Outers: 5x * -8 = -40x

Inners: -7 * 3x = -21x

Lasts: -7 * -8 = 56

Combine them all together:

15x² - 40x - 21x + 56

15x^2 - 61x + 56

Every week, Judy goes to the supermarket and buys the following: $5$ carrots at $\$1$ each, $3$ bottles of milk at $\$3$ each, $
Flauer [41]

Answer:

She spends $30 in total.

Step-by-step explanation:

Suppose that you buy X units of a given product with a price Y, then the total cost here is X*Y, with this we can solve our problem:

Every week Judy buys:

5 carrots, at $1 each, so she spends 5*$1 = $5 in carrots.

3 bottles of milk at $3, so she spends 3*$3 = $9 in milk bottles.

2 pineapples at $4 each (but the pineapples are at half price, so this week the pineapples cost $4/2 = $2), so she spends 2*$2 = $4 in pineapples.

2 bags of flour at $5 each, so she spends 2*$5 = $10 in flour.

1 giant container of ice cream, she spends $7 on it.

So the total money that she speends is:

$5 + $9 + $4 + $10 + $7 = $35

And she has a coupon for $5 in any order equal to or larger than $25, his order is larger than $25, so she can use the coupon.

So she will spend a total of $35 - $5 = $30

She spends $30 in total.

Anita divides 1438 by a multiple of 10. Her answer has a 3 in the tenths column. what number did she divide by?
Ede4ka [16]
<span> For this case, the first thing we are going to do is define a variable.
 We have then:
 x: unknown number and multiplo of 10
 We then have the following number:
 1438
 Dividing between the unknown number we have:
</span> 1438 / x&#10;
<span> As your answer "have a 3 in the tenths column" we have then:
</span> 1438 / x = 14.38&#10;
<span> Clearing x we have:
</span> x = 1438 / 14.38&#10;&#10;x = 100<span>
 Answer:
 Anita divided between the following multiple number of 10:
 x = 100</span>
